[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing a basic configuration of a camera having a self-timer according to a first embodiment of the present invention.

As shown in the figure, the camera of this embodiment
A camera body 5 having a normal photographing function and having a CPU 10 for controlling each unit provided in the camera is provided. A screw 1 of a tripod 13 is provided at the bottom of the camera body 5.
An engagement hole 5a screwed with 3a is formed.
A tripod detection switch 15 that is activated when the screw 13a of the tripod 13 is screwed is provided at the deepest portion of the engagement hole 5a.

A release button 6 and a photographing mode (self-mode) setting button 7 using a self-timer are provided on the upper surface of the camera body 5, respectively. ing.

The CPU 10 is an arithmetic control circuit constituted by, for example, a one-chip microcomputer. If the tripod detection switch 15 is operated, it is determined that the camera is fixed to the tripod, and the self-control is performed even after the photographing is completed. The control unit controls predetermined units so as to continue the mode.

Next, the operation of the camera of this embodiment will be described.

FIG. 2 is a flowchart showing a photographing operation of the camera according to the first embodiment.

First, the CPU 10 detects the operation state of the release button 6 (step S1), and upon detecting the ON signal of the release button 6, determines whether the self mode setting button 7 is operated next. (Step S
2). Here, when the self mode setting button 7 is not turned on and the self mode is not set, normal photographing is performed (step S3).

On the other hand, if the self mode is selected in step S2, a timer built in the CPU 10 for making a waiting time for the self mode is operated, and photographing is performed when the waiting time elapses (step S5).

Thereafter, it is detected by the tripod detection switch 15 whether or not the camera body 5 is fixed to the tripod 13 (step S6), and if it is determined that the switch 15 is turned on and fixed (step S6). Step S7), the self mode photographing is continued (step S9), and when the release button 6 is turned on thereafter, preparation for photographing in the self mode is started again. Therefore, when the release button 6 is operated again,
An image is taken after a predetermined waiting time.

On the other hand, if the camera is not fixed with a tripod in step S7, the self mode is canceled (step S8).

That is, in the camera of the present embodiment, a tripod attachment determination switch is provided in the tripod mounting screw hole of the camera body, and the presence or absence of the tripod is determined by this switch. When shooting in the self mode, the self mode is continued when the camera body is fixed to the tripod, and the shooting in the self mode is canceled only once when the camera body is not fixed to the tripod.

As described above, according to the camera of the first embodiment, when the camera is fixed to the tripod, the photographing in the self mode can be continuously performed. Therefore, it is not necessary to set the self mode every time, so that it is possible to perform comfortable shooting.

Next, a camera according to a second embodiment of the present invention will be described.

In the first embodiment, the tripod mounting determination switch is provided in the tripod mounting screw hole of the camera body, and the presence or absence of the tripod is determined by this switch. Using the results of existing distance measuring means and photometric means, the camera body is fixed to a tripod. Therefore, the tripod detection switch 15 in the first embodiment is not provided.

FIG. 3 is a block diagram showing a basic configuration of a camera having a self-timer according to a second embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 3, the camera according to the second embodiment has two light receiving lenses 1a and 1b and a passive light receiving means for receiving luminance distribution information of a subject received through the light receiving lenses 1a and 1b, respectively. Auto-focus sensor arrays 2a and 2b, an A / D conversion circuit 3 for A / D converting signal outputs of the sensor arrays 2a and 2b, and an A / D
A so-called external light passive autofocus module (a distance measuring device) which is configured with an arithmetic circuit 4 for performing a predetermined operation on the converted signal and obtains a subject distance to the subject based on a deviation amount of luminance distribution information of the received subject. ) 16 is provided.

The A / D conversion circuit 3 and the arithmetic circuit 4 are connected to a CPU 10 having an internal memory. This C
The PU 10 is a control unit that controls the sequence of the entire camera. In addition to the auto-focusing (AF) distance measuring device 16, a focusing lens circuit 8 for a photographic lens, a photometric circuit stage 9 for dew control, a shutter The control circuit 17 and the like are connected and controlled.

Other configurations are the same as those of the first embodiment, and a detailed description thereof will be omitted.

The light receiving lenses 1a and 1b are light receiving lenses for observing an image of the subject 11, and guide the sensor 11 to the sensor arrays 2a and 2b with parallax and the luminance distribution of the subject 11. In the luminance distribution obtained in this manner, a relative displacement is caused by the principle of triangulation based on the parallax, but the sensor outputs constituting the sensor arrays 2a and 2b are output from the A / D converter.
A / D conversion is performed by the conversion circuit 3, and two pieces of digital image information obtained from the output distribution are compared by the calculation circuit 4 to obtain a relative image shift amount X. From the distance f, the subject distance L is obtained by the CPU 10 as L = B · f / X.

As described above, the distance measuring device 16 performs a normal distance measurement operation, and the second embodiment is characterized in that the tripod fixation is detected based on a time change of the distance measurement result. And

Next, the photographing operation in the self mode in the second embodiment will be described. Also in the second embodiment, the photographing operation in the self mode is basically the same as that in the first embodiment (see FIG. 2), and only the tripod fixing detection operation in step S6 is different. FIG. 4 is a flowchart showing a camera fixation detection method (corresponding to the subroutine of tripod fixation detection shown in step S6) in the camera of the second embodiment having the distance measuring device for obtaining the subject distance based on the above-described principle. This will be described with reference to FIG.

First, the CPU 10 resets the number n of times of distance measurement (step S11), and then continues for a predetermined time t.
A timer t for measuring the distance is operated for each one (step S12). Next, it is determined whether or not the time t has reached t1 (step S13), and when it has reached, the distance is measured (step S14). Note that the distance measurement result in this step S14 is Ln.

After step S14, the number n of distance measurement is incremented (step S15), and the number n of distance measurement is compared with a predetermined number n1 (step S16). And
The previous distance measurement result Ln-1 is compared with Ln until n becomes n1 (step S17). Here, Lo is the distance measurement result at the time of shooting.

The absolute value of the difference between Ln and Ln-1 is represented by ΔL
Then, the ΔL is compared with a predetermined value ΔL1 (step S18). Here, if ΔL is smaller than ΔL1, it is determined that the distance measurement result has not changed, that is, the camera is fixed, and the fixed state flag is set (“H” level).
(Step S22).

On the other hand, in step S18, ΔL
Is larger than ΔL1, it is determined that the camera is not fixed, and the fixed state flag is set to “L” level (step S
19).

Thereafter, t = 0 is set again (step S2).
0), the release button 6 is detected (step S21),
If not detected, the process returns to step S12 to repeat the comparison of the distance data.

As described above, in the camera of the second embodiment, the result of the distance measuring device originally mounted on the camera is used without disposing the tripod detection switch as in the first embodiment. This makes it possible to detect the fixed state of the camera.

Next, a third embodiment of the present invention will be described.

The basic configuration of the camera of the third embodiment is the same as that of the second embodiment (see FIG. 3).
However, the second embodiment is characterized in that the fixed state of the camera is detected using the distance measurement result of the distance measurement device 16, whereas the camera of the third embodiment is characterized in that the data of the sensor array is The camera is used to detect the fixed state of the camera.

That is, in the present embodiment, the process of detecting an image shift is omitted, and a higher-speed determination can be performed. In addition, fixed detection can be performed even in a scene where the subject has no contrast and the image shift amount cannot be calculated. It is characterized by the following.

Next, the photographing operation in the self mode in the third embodiment will be described. Also in the third embodiment, the photographing operation in the self mode is basically the same as that in the first embodiment (see FIG. 2), and only the tripod fixing detection operation in step S6 is different. FIG. 6 is a flowchart showing a camera fixing detection method (corresponding to the tripod fixing detection subroutine shown in step S6) in the camera of the third embodiment having the distance measuring device for obtaining the subject distance based on the above-described principle. This will be described with reference to FIG.

FIG. 5 is a diagram showing the output of each sensor of the sensor arrays 2a and 2b for autofocus in the third embodiment. The horizontal axis indicates the arrangement of the sensors, and the vertical axis indicates the A / D conversion result of the sensor output.

In FIG. 6, Steps S31 to S33 are the same as Steps S11 to S13, and a description thereof will be omitted.

In step S33, it is determined whether or not the timer count t has reached t1, and when it has reached, A / D conversion of each sensor of the sensor arrays 2a and 2b is performed (step S34). Thereafter, Steps S35 and S36 are the same as Steps S15 and S16, and a description thereof will be omitted.

Now, the sensor that looks at the center of the screen changes from Sx to S
In the case of x + w (w + 1) sensors, the CPU 10 inputs the sensor outputs in this section in time series and detects the fixed state of the camera by the amount ΔS obtained by adding the absolute value of the difference (step S37). . Thereafter, the ΔS is compared with a predetermined value ΔS1 (step S38).

Here, when ΔS is larger than ΔS 1, it is considered that the scene viewed by the sensor array has changed.
The camera is considered to be moved and not fixed. Therefore, the fixed state flag is set to "L" level (step S40). On the other hand, if ΔS is smaller than ΔS1, it is determined that the camera is fixed, and the fixed state flag is set to “H” level (step S39). Subsequent step S4
Steps S1 and S42 are the same as steps S20 and S21, and a description thereof will be omitted.

As described above, according to the camera of the third embodiment, the result of the distance measuring device originally mounted on the camera is used without disposing the tripod detection switch as in the first embodiment. This makes it possible to detect the fixed state of the camera.

As described above, according to the cameras of the second and third embodiments, a fixed state of the camera can be detected based on a result of distance measurement or a change in image data. When such a method is applied to the first embodiment, the self mode is automatically extended in a scene in which shooting in the self mode is repeatedly performed, and a mode in which self shooting is unnecessary is detected. Since the cancellation is performed, self-timer shooting without failure becomes possible.

Next, a fourth embodiment of the present invention will be described.

The first to third embodiments are similar to those shown in FIG.
As shown in FIG. 7, a scene in which the photographer 12 enters the photo screen together with the subject 11 is assumed. However, the camera of the fourth embodiment can correctly perform the self-photographing even in a situation where only the photographer wants to enter the photo screen. It is characterized in that automatic setting can be performed.

The camera according to the fourth embodiment has basically the same configuration as that of the second and third embodiments, and a detailed description thereof will be omitted.

In the second and third embodiments, the fixed camera is detected based on the result of the distance measurement or the sensor data as described above. It is assumed that a subject other than exists. In the fourth embodiment, there is no subject other than the photographer, and the photographer is assumed to perform photographing in a self mode in which the photographer himself enters a photograph screen. Hereinafter, a situation in such a self-mode shooting will be briefly described with reference to FIG.

In FIG. 7, first, it is assumed that the photographer 12 is operating the camera 5 at the timing of T1 in the upper stage. Next, in the middle stage, the photographer 12 sets the photographing in the camera 5 in the self mode, presses the release button, and performs photographing at the timing of T2. At this time, there is a failure, and the photographer 12 tries to photograph again in the self mode at the timing of T3 (lower part). At this time, the photographer 12 has returned near the camera 5.

In such a scene, since the distance measurement results or sensor data of T2 and T3 are changed, the self mode may be canceled. The camera of the fourth embodiment has been made in view of such circumstances, and addresses such problems.

Hereinafter, the photographing operation in the self mode according to the fourth embodiment will be described with reference to the flowchart shown in FIG.

First, as in the first embodiment, the release switch and the self mode are determined (step S).
51, step S52), when not in the self mode, normal distance measurement and photographing are performed (steps S53, S5).
4).

On the other hand, if the photographing in the self mode is set in step S52, the distance measurement (the timing of T1 in FIG. 7) is immediately performed (step S61), and the timer is counted (step S6).
2) After a predetermined time of the self-timer, the distance measurement (the timing of T2 in FIG. 7) is performed again (step S6).
3). Then, focusing is performed based on the distance measurement result (LT2), and photographing is performed (step S64). Next, a timer count for repeated distance measurement after photographing is performed (step S65), and then distance measurement is again performed (T3 in FIG. 7).
Is performed (step S66). The distance measurement result LT3 is compared with the distance measurement result LT1 at the timing of T1, and a difference is obtained (step S67).

The difference ΔL of the distance measurement result obtained in this manner is the distance measurement result of T1 and T3 in the scene shown in FIG. 7, and is the difference between the results of distance measurement of the background. Instead, moving the camera will cause a difference if the background or subject is changing.

Based on the above concept, ΔL and the predetermined value Δ
L1 is compared with the predetermined value ΔL1 (step S68). If the above-mentioned ΔL is smaller than the predetermined value ΔL1, it is considered that the camera body is still fixed to the tripod, and the self mode is continued (step S70). Releases the self mode assuming that the camera has been moved (step S6).
9). This control is performed by the CPU 10.

As described above, in the fourth embodiment, even if only the photographer himself has the subject, the self-timer mode is automatically continued and canceled correctly, so that self-timer shooting without failure can be performed. It becomes possible.

In the second to fourth embodiments, the fixed state of the camera is detected based on the output signal from the distance measuring device 16. However, the present invention is not limited to this. It is also possible to detect the fixed state of the camera using a sensor for prevention.

Next, a fifth embodiment of the present invention will be described.

The camera of the fifth embodiment has the same basic configuration as the second to fourth embodiments, but the focusing accuracy of the autofocus camera is determined by repeatedly measuring the distance. The present invention focuses on improving the reliability of the camera, and provides a highly accurate autofocus camera. Therefore, only the difference will be mentioned here, and the other configuration and operation will be duplicated, and the description will be omitted.

Hereinafter, the photographing operation of the camera having the self-timer according to the fifth embodiment will be described with reference to the flowchart shown in FIG.

First, when sensor data is repeatedly acquired in steps S71 and S72, the same process as that of the third embodiment (see FIG. 6) is performed (see FIG. 6).
And the difference between the two sensor data input in S72
S (step S73), the ΔS is compared with a predetermined value ΔS1, and the degree of coincidence of these data is calculated.

If the degree of coincidence is high in step S74, the distance is calculated using the sensor data input in steps S71 and S72 (step S7).
5, S76). Next, the distance is averaged based on the result (step S77), the focusing distance is determined (step S78), and the image is taken (step S79).

On the other hand, if the coincidence is low in step S74, the focusing distance is calculated from the sensor data obtained in step S72 (steps S80 and S8).
1, S78), and photographing (step S79).

As described above, according to the camera of the fifth embodiment, if the relationship between the camera and the subject is fixed,
Since the focusing distance does not change during photographing, a camera having a more accurate autofocus function can be provided by performing distance measurement a plurality of times.

Next, a sixth embodiment of the present invention will be described.

The camera according to the sixth embodiment is similar to the camera according to the fifth embodiment.
As in the third embodiment, a more accurate autofocus function is obtained by performing distance measurement a plurality of times in a scene where the camera is fixed.

FIG. 10 is a block diagram showing a configuration of a distance measuring device in a camera having a self-timer according to a sixth embodiment of the present invention. Note that the same reference numerals are given to the same components as those in each of the above embodiments, and detailed description thereof will be omitted.

The camera of the sixth embodiment has the same basic configuration as that of the second embodiment, except for the configuration of the distance measuring device. Therefore, only the difference will be mentioned here, and the other configuration and operation will be duplicated, and the description will be omitted.

As shown in FIG. 10, in the distance measuring apparatus 20 of the sixth embodiment, the auto-focus sensor arrays 2a and 2b are connected to integrating circuits 18a and 18b, respectively. The output photocurrents are each integrated into the circuit. Further, the integration circuit 18
Both a and 18b are connected to an integration time determination circuit 19, and an output signal of the determination circuit 19 is input to the CPU 10.

The integration time determination circuit 19 also functions as the A / D conversion circuit in the second embodiment, and measures the time until the output signal levels from the integration circuits 18a and 18b reach a predetermined level. It is designed to convert to digital values.

FIG. 11 is a flowchart showing a self-mode photographing operation in the camera of the sixth embodiment.

Now, the result obtained by the integration time determination circuit 19 determining the timing at which the output of the sensor at the center of the screen reaches a predetermined level is defined as Ts. The integration time is measured a plurality of times (steps S91 and S92). If the result does not change (steps S93 and S94),
Since the relationship between the camera and the subject 11 is considered to be fixed, in that case, the distance measurement is performed a plurality of times with priority given to the accuracy of the distance measurement over the timing (step S95), and the average value is calculated (step S95). (Step S96), the focusing distance is determined (Step S98), and the image is taken (Step S9).
9). If the measurement result changes (steps S93 and S94), normal photographing is performed assuming that the relationship between the camera and the subject 11 is not fixed (step S97).
-Step S99).

As described above, according to the camera of the sixth embodiment, since the fixed state of the camera is determined by using only the integral value of a part of the sensor, the fixed state of the camera can be determined more simply and at higher speed. Becomes

As described above, according to each of the above-described embodiments, the camera has a function of determining whether or not to continue self-photographing when photographing with the self-timer. Photographing without failure becomes possible.

Further, the function of detecting the fixed state of the camera can be used to make it possible to design such that the distance measurement accuracy can be improved.
