For example, since the magnitude of the second output signal is increased, a code value (or data) corresponding to the second output signal V2 of the second position sensing unit 72 may be increased, and the third lens assembly 624 may be It is possible to improve the sensitivity of the second position sensing unit 72 with respect to motion, thereby improving the resolution of the camera device. In this case, the code value may be a code value (or data) preset through calibration.

21 illustrates an arrangement relationship between the first magnet 130A and the first position sensing unit 71 .

Referring to FIG. 21 , as the second lens assembly 622 moves in the first direction, the relative position between the first position sensing unit 71 and the first magnet 130A may change.

The first sensor 71A and the second sensor 71B may be arranged in a first direction or parallel to a first surface of the first magnet 130A. In this case, the first surface of the first magnet 130 may include an N pole and an S pole.

For example, when the second lens assembly 622 is positioned at the center point of the movement range (or stroke section) in the first direction, the center line 401 of the first magnet 130A (or the boundary line between the N pole and the S pole) ), the first sensor 71A may be located opposite the second sensor 71B. For example, the center line 401 may be a straight line parallel to the third direction and passing through the boundary line between the N pole and the S pole. For example, the first sensor 71A and the second sensor 71B may be symmetrically disposed with respect to the center line 401 of the first magnet 130A. In another embodiment, the first sensor 71A and the second sensor 71B may not be symmetrically disposed with respect to the center line 401 of the first magnet 130A.

Or, for example, when the second lens assembly 622 is located at the front end point or the rear end point of the movement range (or stroke section), the first sensor 71A and the first sensor 71A with respect to the center line 401 of the first magnet 130A. The second sensors 71B may be located on the same side.

The first distance d1 between the first sensor 71A and the second sensor 71B in the first direction, and the first magnet 71A (or the second sensor 71B) and the first magnet in the third direction The second distance d2 between the first magnets 130A is related to the linearity of the output signal V1 of the first position sensing unit 71 and the intensity of the output according to the displacement of the first magnet 130A. In this case, in order to increase the accuracy of the position sensing of the second lens assembly, linearity should be good.

22 shows simulation results for the output of the first position sensing unit 71 for three cases (CASE1 to CASE3).

In the graph of FIG. 22 , the X-axis represents the movement range, displacement, or stroke range of the second lens assembly 622 (or the first magnet 130A), and the Y-axis represents the first magnet 130A detected by the first position sensing unit. Indicates the strength of the magnetic field.

CASE1 is the simulation result under the condition that d1 is 1 [mm], CASE2 is the simulation result under the condition that d1 is 1.1 [mm], and CASE3 is the simulation result under the condition that d1 is 1.2 [mm].

When the first position sensing unit includes only one Hall sensor, g1 represents a code value corresponding to an output of the single Hall sensor. g2 denotes a code value corresponding to an output of any one (eg, 71A) of the first and second sensors 71A and 71B of the first position sensing unit 71 , and g3 denotes a code value corresponding to the output of the first position sensing unit 71 . ) represents a code value corresponding to the output of the other one (eg, 71B) of the first and second sensors 71A and 71B, and g4 is the serial connection of the first and second sensors 71A and 71B. Code values corresponding to the first output signals at both ends of the output terminals ( 94A and 92B in FIG. 19A ) are indicated.

Referring to FIG. 22 , in order to accurately detect the position of the second lens assembly 622 , the linearity of the slope of the output (or code value) of the Hall sensor in the movement range of the second lens assembly 622 or the entire stroke section is should be good For example, the entire stroke section of the second lens assembly 622 may be a section in which the second lens assembly can be physically or mechanically moved. Alternatively, for example, the full stroke section of the second lens assembly 622 may be a driving section for the zooming operation, which may be narrower than the physical or mechanical full stroke section.

In particular, linearity in the vicinity of the first point PO1 (hereinafter, referred to as a “first section”) and near the second point PO2 (hereinafter referred to as a “second section”) should be good.

The first point PO1 may be a front end position (0.0 [mm]), and the second point PO2 may be a rear end position (3.0 [mm]). For example, the first section may range from the first point PO1 to the first point PO1 + K1 [mm]. The second section may range from the second point PO2 to the second point PO2 - K2 [mm].

For example, 0.3 [mm] ≤ K1, K2 ≤ 1 [mm] may be. Or, for example, 0.4 [mm] ≤ K1, K2 ≤ 0.6 [mm] may be.

An important point in determining the linearity may be the first section and the second section. In this embodiment, in the first section or the second section, the ratio (code) of the position or stroke distance of the second lens assembly 622 to the first output signal of the first position sensing unit 71 (code) When the stroke/code) is 1 micrometer/unit code (1 [㎛/code] or less, it can be said that the linearity is good.

When d1 is 1.0 [mm] (CASE 1 of FIG. 22 ), a ratio (stroke/code) of a code value corresponding to the first output signal of the first position sensing unit 71 is 0.5 micrometer/unit Code (1 [㎛/code] may be or less. However, if the ratio is 0.5 micrometer/unit code (1 [㎛/code] or less), the sensitivity or resolution of the first position sensing unit 71 is too low, The second lens assembly 622 may hardly move, so in consideration of the sensitivity or resolution of the first position sensing unit 71, d1 may be set to be greater than or equal to 1.02 [mm] in the embodiment. .

When d1 is 1.1 [mm] (CASE 2 in FIG. 22 ), in the first section or between the second stations, the ratio of the code value (code) corresponding to the first output signal of the first position sensing unit 71 (stroke) /code) can be 1 micrometer/unit code (1 [㎛/code] or less. Therefore, when d1 is 1.1 [mm], linearity may be good.

When d1 is 1.2 [mm] (CASE 3 of FIG. 22 ), the ratio of the code value (code) corresponding to the first output signal of the first position sensing unit 71 in the first section or the second section code) may be greater than 1 micrometer/unit code (1 [㎛/code]. Therefore, in an embodiment, d1 may be set to be less than 1.2 [mm] in order to obtain good linearity.

When combining CASE 1 to CASE 3, it may be 1.02 [mm] ≤ d1 ≤ 1.18 [mm]. That is, in order to secure stable linearity, d1 may be set to be less than or equal to 1.18 [mm]. Alternatively, for example, 1.05 mm ≤ d1 ≤ 1.15 mm, 1.05 mm < d1 ≤ 1.1 mm, or 1.1 mm ≤ d1 < 1.15 mm to ensure more stable linearity.

Also, in CASE 2, g4 may have good linearity in the entire stroke section including the first section and the second section when compared to g1 to g3.

Referring to FIG. 21 , the second distance d2 between the first sensor 71A (or the second sensor 71B) and the first magnet 130A in the third direction is 0.4 [mm] to 1.5 [mm] can be

Or, for example, d2 may be 0.4 [mm] to 1.1 [mm]. Or, for example, d2 may be 0.8 [mm] to 1.05 [mm].

When d2 is less than 0.5 mm, the strength of the first output signal of the first position sensing unit 71 or the strength of the magnetic field of the first magnet 130A sensed by the first position sensing unit 71 is very strong, but 2 The linearity of the slope of the graph of the movement range (or stroke section) of the lens assembly 622 and the data output from the first position sensing unit 17 may deteriorate, and thus the accuracy of the AF operation may be deteriorated.

In addition, when d2 is greater than 1.5 mm, the strength of the first output signal of the first position sensing unit 71 or the strength of the magnetic field of the first magnet 130A detected by the first position sensing unit 71 is very small, It is difficult to accurately sense the position of the second lens assembly 622 , and the sensitivity of the position sensing may be lowered.

The result of d1 of FIG. 22 may be applied or applied mutatis mutandis to the correlation between the second position sensing unit 72 and the second magnet 130B. Also, the description of d2 between the first position sensing unit 71 and the first magnet 130A may be applied or applied mutatis mutandis to the correlation between the second position sensing unit 72 and the second magnet 130B.

For example, the movement range of the second lens assembly 622 or the length of the entire stroke section may be smaller than the movement range of the third lens assembly 624 or the length of the entire stroke section. In another embodiment, the former may be the same as or less than the latter.

For example, the ratio (LK1/d1) of the movement range of the second lens assembly 622 or the length of the entire stroke section (LK1) to d1 (LK1/d1) may be 1.5 to 3. Alternatively, for example, the ratio (LK1/d1) of the length LK1 of the entire stroke section of the second lens assembly 622 to the ratio d1 may be 2 to 2.2. Alternatively, the ratio (LK1/d1) may be 1.96 to 2.26.

When the ratio (LK1/d1) is less than 1.5, the linearity of the correlation between the output (or code value) of the first position sensing unit 71 with respect to the movement range (or stroke) of the second lens assembly 622 is deteriorated, so that an accurate Zooming cannot be performed. In addition, when the ratio (LK1/d1) is greater than 3, the linearity may deteriorate and the sensitivity of the first position sensing unit 71 may decrease.

For example, the ratio (LK2/d1) of the length LK2 of the movement range (or stroke) of the third lens assembly 624 and d1 may be 2.3 to 3.5. Alternatively, LK2/d1 may be 2.5 to 3. Alternatively, LK2/d1 may be 2.92 to 3.38.

When the ratio (LK2/d1) is less than 2.3, the linearity of the correlation between the output (or code value) of the second position sensing unit 72 with respect to the movement range (or stroke) of the third lens assembly 624 is deteriorated, so that an accurate Focusing cannot be performed. Also, when the ratio (LK2/d1) is greater than 3.5, the linearity may deteriorate and the sensitivity of the second position sensing unit 72 may decrease.

In the second driving unit 70 , a path of light incident to the optical member 40 by the movement of the holder 30 coupled to the optical member 40 is perpendicular to the first axis (optical axis or Z axis) (eg, XY plane), thereby moving the image formed on the image sensor 540 in the X-axis direction and/or the Y-axis direction. That is, by controlling the movement of the holder 30 , the embodiment can correct blurring of an image or shake of a moving picture caused by shaking in a camera device when taking an image or a video due to a user's hand shake.

The first position sensor unit 170 receives the first driving signal DI1 and supplies the received first driving signal DI1 to the first sensor 71A and the second sensor 71B. The first position sensor unit 170 receives the second driving signal DI2 and supplies the received second driving signal DI2 to the third sensor 72A and the fourth sensor 72B.

In addition, each of the first sensor 240A and the second sensor 240B may detect a displacement of the holder 30 in the third axis direction, and may output an output signal according to the sensed result.

Alternatively, in another embodiment, the input terminals of the first and second sensors 240A and 240B may be connected in parallel to the first sensor 240A and the second sensor 240B as described with reference to FIG. 19A , and the first and second sensors 240A and 240B may be connected in parallel. Output terminals of the two sensors 240A and 240B may be serially connected, and one output signal may be output from both ends of the serially connected output terminals.

The second OIS position sensor 240C may detect the displacement of the holder 30 in the second axis direction, and may output an output signal according to the sensed result.

The storage unit 180 stores data necessary to operate the camera device 200 . The storage unit 180 may be expressed by replacing it with “memory”. For example, the storage unit 180 may store information on a zoom position and a focus position for each distance from a subject.

For example, the storage unit 180 stores the first reference code for the first output signal V1 of the first position sensing unit 71 corresponding to the movement range (or stroke range or displacement) of the second lens assembly 622 . It can store values (or data). Also, the storage unit 180 stores a second reference code value for the second output signal V2 of the second position sensing unit 72 corresponding to the movement range (or stroke range or displacement) of the third lens assembly 624 . (or data) can be stored. The first and second reference code values may be values previously stored in the storage unit 180 through calibration.

The storage unit 180 may be configured separately from the control unit 810 , but is not limited thereto, and may be included in the control unit 810 in another embodiment. For example, the storage unit 180 may be included in at least one of the first driver 542 and the second driver 260 .

For example, the camera apparatus 200 may be accurately focused based on the target position of the second lens assembly 622 and the target position of the third lens assembly 624 .

The image sensing unit 330 may include an image sensor 540 that converts light reflected from the subject into an electrical signal. For example, the image sensor 540 may include a light receiving unit that receives light and converts it into an electrical signal, and an analog-to-digital converter that converts the converted electrical signal into a digital signal. Also, for example, the image sensor 540 may further include an image signal processor that performs signal processing on a digital signal.

The controller 810 controls the overall operation of the camera device 200 . For example, the control unit 200 may control the first position sensor unit 170 and the second position sensor unit 240 to provide an anti-shake function, an auto focus function, and a magnification adjustment function, and the first driving unit ( 630 ) and the second driving unit 70 may be driven. For example, the controller 810 may include a first driver 542 and a second driver 260 . For example, each of the first driver 542 and the second driver 260 may include at least one of an analog-to-digital converter, an amplifier, a PID controller, or a memory.

The first driver 542 includes the first output signal V1 of the first position sensing unit 71 of the first position sensor unit 170 and the second position sensing unit 72 of the first position sensor unit 170 . may receive the second output signal V2 of

The first driver 542 generates a first code value according to a result of analog-to-digital conversion of the received first output signal V1, and based on a result of comparing the generated first code value with a first target value The first driving signal applied to the first coil 120A of the first driving unit 630 may be controlled. For example, the first target value may be a reference code value corresponding to a target zoom position of the second lens assembly 622 .

In addition, the first driver 542 generates a second code value according to a result of analog-digital conversion of the received second output signal V2 and compares the generated second code value with a second target value based on the result Thus, the second driving signal applied to the second coil 120B of the first driving unit 630 may be controlled. For example, the second target value may be a reference code value corresponding to a target focus position of the third lens assembly 624 .

The second driver 260 may receive a first output signal of the first OIS position sensors 240A and 240B of the second position sensor unit 240 and a second output signal of the second OIS position sensor 240C. .

The second driver 260 generates a third code value according to the analog-digital conversion result of the first output signal of the received first OIS position sensors 240A and 240B, and the generated third code value and the third target The first driving signal applied to the first OIS coils 230A and 230B of the second driving unit 70 may be controlled based on the result of comparing the values.

In addition, the second driver 260 generates a fourth code value according to the analog-digital conversion result of the second output signal of the received second OIS position sensor 240C, and generates the fourth code value and the fourth target value. A second driving signal applied to the second OIS coil 230C of the second driving unit 70 may be controlled based on a result of comparing .

For example, the third target value is a reference code value related to the output of the first OIS position sensors 240A and 240B corresponding to the target second axis (X axis) tilting position of the OIS movable part of the second actuator 320 (or data) can be Also, for example, the fourth target value is a reference code value (or data) related to the output of the second OIS position sensor 240C corresponding to the target third-axis (Y-axis) tilting position of the OIS movable part of the second actuator 320 . ) can be The reference code value (or data) related to the output of each of the first OIS position sensors 240A and 240B and the second OIS position sensor 240C may be preset through calibration and stored in the storage unit 180 .

The camera device 200 may further include a temperature sensor 566 for temperature compensation. The temperature sensor 566 may output temperature information according to a result of measuring the temperature of the camera device 200 .

The temperature information of the temperature sensor 566 may be used for temperature compensation for the focusing operation of the third lens assembly 624 . For example, the storage unit 180 may store a compensation value corresponding to the temperature information.

For example, since the second lens assembly 622 in charge of zooming moves according to the magnification set by the user, in a state (or condition) in which the position of the second lens assembly 622 is fixed (or condition), the third lens assembly 622 in charge of autofocusing Temperature compensation may be performed on the lens assembly 624 .

24 shows simulation results for temperature compensation. 24 shows simulation results for four samples. The four samples may be third lens assemblies of different camera devices, and FIG. 24 may be a simulation result at a preset zoom position and a corresponding one focus position. In another embodiment, the number of samples may be one or two or more.

The X-axis represents the temperature measured by the temperature sensor, the left Y-axis value represents a code value corresponding to the output of the position sensing unit (eg, the second position sensing unit 72 ), and the right Y-axis value corresponds to the sharpness can be a value.

First, for calibration for temperature compensation, a plurality of temperatures (hereinafter, referred to as “sampling temperature”) are set. For example, in FIG. 24, five temperatures (eg, -20 degrees Celsius (°C), 0 degrees, 20 degrees, 40 degrees, and 60 degrees) may be sampled and set, but the present invention is not limited thereto, and in another embodiment Two or more temperatures may be selected and set.

Next, at a preset zoom position (eg, 1x zoom, or N (a rational number, N > 1) times zoom) of the second lens assembly 622 of each of the samples, each of the samples at each sampling temperature is 3 An optimal focus position of the lens assembly 624 is detected.

In FIG. 24 , a square (■) denotes a second output signal of the second position sensing unit 72 of the third lens assembly 624 corresponding to an optimal focus position of the third lens assembly 524 at each sampling temperature. may be a code value corresponding to . Here, the code value may be a value obtained by analog-digital conversion of the second output signal.

In FIG. 24 , a diamond (♦) may be an optimal spatial frequency response (SFR) value at an optimal focus position of the third lens assembly 624 . In an embodiment, the SFR value may be used to determine the optimal focus position. SFR is a measurement method made based on the MTF (Modulation Transfer Function) theory, and the resolution of a digital camera can be analyzed using SFR.

For example, the square (■) may be a code value corresponding to the second output signal of the second position sensing unit 72 of the third lens assembly 624 having the highest SFR value at each sampling temperature.

For example, the SFR may be measured for at least one pixel in the active area of the image sensor 540 . For example, the measurement may be performed with respect to a pixel located at the exact center of the active area of the image sensor 540 .

Next, code values corresponding to the sampling temperatures are interpolated by interpolation, and an interpolation formula or interpolated data is obtained based on the interpolation result. For example, the interpolation method may include at least one of various interpolation methods. For example, the interpolation method is linear interpolation, polynomial interpolation, spline interpolation, exponential interpolation, log_linear interpolation, Lagrange interpolation, Newton Interpolation (Newton Interpolation) and two-dimensional interpolation (Bilinear Interpolation) may be included.

For example, an interpolation equation or interpolation data corresponding to each of a plurality of samples may be obtained. For example, four interpolation equations (eg, Y1, Y2, Y3, Y4) corresponding to four samples may be obtained.

Next, an average of slopes of interpolation equations (or interpolation data) of samples may be calculated or calculated, and the calculated average may be set as a slope of a new interpolation equation for each sample. For example, the y-intercept value of the new interpolation equation for each sample may be the y-intercept value of the original interpolation equation (Y1, Y2, Y3, Y4).

Next, a compensation value is calculated using a new interpolation equation (eg, the slope of the new interpolation equation), and the calculated compensation value is stored in the storage unit 180 or the control unit 810 (eg, the first driver 542 ). can be

For example, the reference code value (or reference data) of the second position sensing unit 72 according to the focus position of the AF lens unit may be set at a preset temperature (eg, room temperature) through calibration, and the reference code value (or reference) data) may be stored in the storage unit 180 .

For example, FIG. 24 may be an optimal code value (or data) regarding an output of the second position sensing unit corresponding to an optimal focus position according to temperature. For example, the compensation value may be a difference between the optimal code value of FIG. 24 and the reference code value.

For example, the controller 810 (eg, the first driver 542 ) may generate a compensation value for temperature compensation at a preset temperature based on the new interpolation equation. In this case, the compensation value for temperature compensation may be a difference between an optimal code value generated by an interpolation equation and a reference code value.

Also, for example, the controller 810 receives temperature information from the temperature sensor 566, obtains a compensation value for temperature compensation corresponding to the received temperature information, and based on the obtained compensation value, the third lens assembly 624 ) to control the driving signal of the second coil 120B. For this reason, in the embodiment, an accurate auto-focusing operation reflecting the temperature compensation may be performed.

For example, compensation values at all zoom positions and corresponding focus positions of the second lens assembly 622 may be set as described above, but are not limited thereto. In another embodiment, interpolation equations are obtained as described above with respect to two or more other preset zoom positions of the second lens assembly 622 and two or more focus positions corresponding thereto, and using the obtained interpolation equations Interpolation equations for zoom positions other than the preset two or more other zoom positions and other focus positions corresponding thereto may be obtained, calculated, or generated, and the obtained interpolation equations may be stored in a storage unit. . In addition, compensation values for other zoom positions and other focus positions corresponding thereto may be obtained, calculated, or generated using the obtained interpolation equations.

For accurate zooming and autofocus operations, the zoom position of the second lens assembly 622 and the focus position of the third lens assembly 624 must be set in consideration of the distance (or separation distance) between the subject and the camera device (or lens). do. This setting process is called "calibration" or "zoom calibration". The distance to the subject may be obtained using a range finder (eg, a laser diode) provided in the camera device.

For example, when the distance between the camera device (or the user) and the subject is long, the zoom magnification may be set to a high magnification or changed to a high magnification. On the other hand, when the distance between the camera device and the subject is short, the zoom magnification may be set to a low magnification or changed to a low magnification.

A stroke or displacement of the second lens assembly 622 may be set or changed based on the zoom magnification. A position at which the second lens assembly 622 should be located or moved so as to realize an accurate zoom magnification as described above is referred to as a “zoom position”.

In addition, the position, displacement, or stroke of the third lens assembly 624 for accurately focusing the subject at the “zoom position” of the second lens assembly 622 is referred to as a “focus position”. Accordingly, the focus position may change according to the “zoom position” and distance information from the subject.

25 shows a zoom calibration method according to an embodiment, FIG. 26 shows the sampling points of FIG. 25 , and FIG. 27 shows the sampling points of FIG. 25 and interpolation data obtained based on the sampling points.

25 to 27 , the number of distances between the subject and the camera device is set ( S110 ). For example, the number of distances may be set to two to include a first distance (infinity) and a second distance (eg, macro), otherwise three or more including infinity and a distance between macros may be set to include

Although it is illustrated in the drawings as including only data on the zoom position and the focus position corresponding to the first distance and the second distance, the present invention is not limited thereto. For example, the distance between the subject and the camera device may further include at least one distance positioned between the first distance and the second distance.

That is, there is a model in which the camera device requires only data on the zoom position and the focus position for the first and second distances as described above, and differently, data on the zoom position and the focus position for three or more distances Some models require Accordingly, the number of distances may be set differently depending on the model of the camera device.

Next, sampling points regarding the zoom position of the second lens assembly 622, which are zoom lenses, are set at the set number of distances (S120).

Referring to FIG. 26 , the sampling points may include a plurality of zoom positions (eg, ZP1 to ZP5).

For example, the sampling points may be set in a range from a wide position (eg, 1x or 3x) to a high magnification position (eg, 5x).

For example, an interval between two neighboring sampling points may be equal to each other. For example, the interval between sampling points may be set as a default value. For example, five sampling points may be set.

Although it is illustrated that the same sampling point or the same sampling interval is set for each of the first distance (Infinity) and the second distance (Macro), the sampling interval may be set differently according to each distance.

Next, data on a position (eg, a zoom position) of the second lens assembly 622 that is a zoom lens is acquired at each of the sampling points ZP1 to ZP5 ( S130 ).

For example, data regarding the position of the second lens assembly 622 at the sampling points ZP1 to ZP5 may be acquired using preset data regarding the stroke or position of the second lens assembly 622 .

or the position of the second lens assembly 622 at the sampling points ZP1 to ZP5 using, for example, at least one of the first position ZP1, the second position ZP5, and the spacing between the sampling points ( For example, data (ZC[0] to ZC[4]) regarding the zoom position) may be acquired.

Next, data on an optimal position (eg, a focus position) of the third lens assembly 624 is acquired at each of the sampling points ZP1 to ZP5 .

For example, data regarding the optimal position of the third lens assembly 624 at each of the sampling points ZP1 to ZP5 may be acquired for each of a set number of distances (eg, infinity and macro).

For example, after positioning the second lens assembly 622 at the set sampling points ZP1 to ZP5 , the second lens assembly 624 is moved and the SFR value is measured, so that the focus position of the second lens assembly 622 is data can be obtained.

For example, by measuring an SFR value for at least one pixel (eg, a pixel located in the center) of the active area of the image sensor 540 , data regarding the position of the second lens assembly 624 when the SFR value is the highest It can be set with data about the "focus position".

For example, the data regarding the zoom position may be a code value according to a result of analog-to-digital conversion of the first output signal of the first position sensing unit 71 that detects the position of the second lens assembly 622 , and is located at the focus position. The related data may be a code value according to a result of analog-digital conversion of the second output signal of the second position sensing unit 72 that detects the position of the third lens assembly 624 .

Accordingly, in order to perform the zooming and AF operations, data on the zoom position and data on the focus position corresponding to the zoom position should be stored in the controller 810 or the storage unit 180 .

27 shows data Mac1 to Mac5 regarding the focus position of the third lens assembly 622 with respect to sampling points ZP1 to ZP5 at the macro position. Also shown is data InF1 to InF5 regarding the focus position of the third lens assembly 622 with respect to the sampling points ZP1 to ZP5 at the Infinity position.

Next, an interpolation formula or interpolation data for points other than the sampling points ZP1 to ZP5 is obtained by using the data about the zoom position and the data about the focus position for the sampling points ZP1 to ZP5. or calculate (S160). For example, interpolation expression or interpolation data may be obtained for a set number of distances (eg, infinity, macro).

For example, interpolation data for zoom positions and focus positions of points other than the sampling point may be obtained by applying any one of the above-described interpolation methods.

For example, by applying an interpolation method to two neighboring sampling points (ZP1 and ZP2, ZP2 and ZP3, ZP3 and ZP4, ZP4 and ZP5), an interpolation equation (eg, four interpolation equations) can be generated, and the generated Data (eg, Mac1 to Mac5, InF1 to Inf5) regarding the zoom position and the focus position may be obtained or calculated by the interpolation equation.

Next, the obtained interpolation data or interpolation expression may be stored in the storage unit 180 or the control unit 810 .

In an embodiment, data about the entire zoom position and the entire focus position may not be stored for each distance between the subject and the camera device, but only data regarding the zoom position and focus position for a specific sampling point set for each distance may be stored. For this reason, in the embodiment, the size of the memory can be minimized, and thus the manufacturing cost can be reduced.

28 illustrates a zooming and focusing operation method according to an embodiment.

For example, the distance information may be a distance between the subject and the third lens assembly of the camera device 200 .

Next, the controller 810 acquires zoom magnification information (S220). Here, the zoom magnification information may be information about a zoom position of the second lens assembly 622 provided by a user.

Next, by using the obtained distance information and interpolation data or interpolation equation regarding the zoom position and focus position obtained through the zoom calibration of FIGS. 25 to 27 , zoom position data and focus position data matching the zoom magnification are obtained do (S230).

For example, if the distance to the subject corresponds to a macro and the zoom magnification corresponds to the third zoom position ZP3 in FIG. 27 , interpolation data or data about the zoom position and focus position obtained using the interpolation equation are “Mac3 "It could be

Next, the movement of the second lens assembly 622, which is a zoom lens, is controlled based on the acquired data on the zoom position (S240), and the third lens assembly that is a focus lens based on the acquired data on the focus position (S240). 624) to control the movement.

In an embodiment, interpolation data is obtained using sampling data, and the zoom position and focus position can be adjusted according to the distance from the subject by applying the interpolation data.

That is, when distance information from a subject is obtained and the zoom position (or zoom magnification) is changed accordingly, the focus lens needs to be moved to a focus position corresponding to the distance information and the zoom position. At this time, according to the embodiment, the storage unit 180 stores the data regarding the zoom position and the focus position with respect to the movement range (or the full stroke range) of each of the second lens assembly 622 and the third lens assembly 624 . No, only sampling data for zoom positions and focus positions for specific sampling points are stored. In an embodiment, interpolation data regarding zoom positions and focus positions of other points located between sampling points are acquired using interpolation. In addition, when the interpolated data is obtained, accurate zooming and autofocusing operations may be performed by adjusting the focus position of the focus lens and the zoom position of the zoom lens using the obtained interpolation data.
