[0002]

2. Description of the Related Art Conventionally, in photographing using a remote controller, when a push button of the remote controller is pressed, the closest distance among the distances to the subject obtained by a plurality of ranging areas is detected. The subject is focused on, and the subject is photographed by regarding the subject as a person using a remote control.

However, in such conventional remote-control photographing, a photographer using the remote control is required to determine whether the photographer is in focus or not, and how far the photographer is focused. I couldn't tell if he was there, so I had to do the shooting with the camera. By the way, when shooting with a remote control, if the person using the remote control can know the in-focus or out-of-focus state, or if it can know how far the focused distance is, it will fail. It is very convenient for remote-less shooting without any.

[0004]

The control means, as the focusing distance of the subject by the focusing means becomes long,
The lighting of each of the distance indicating lamps may be controlled so that the number of lighting of the distance indicating lamps is increased. further,
The control means controls the lighting of each of the distance display lamps so that all the distance display lamps blink when the focusing means cannot focus on the subject. Further, the distance indicating lamps may be arranged in a line in front of a camera body.

[0006]

The auxiliary light projecting unit 20 is a part that emits auxiliary light for assisting the distance measurement when the passive AF sensor unit 18 cannot measure the distance to the subject because the surrounding area is dark. The strobe light emitting unit 22 is a unit that emits strobe light to assist shooting when the surroundings are dark.

The seven distance display lamps 23 use LEDs, and display an approximate focusing distance according to the number of lighted LEDs. When the subject cannot be focused, all the distance display lamps 23 blink. Therefore, by looking at the lighting and blinking states of the distance display lamp 23, the person using the remote controller can know the in-focus state and the out-of-focus state, and how long is the focused distance. Will be able to know.

Then, remote control shooting of the subject is performed.

FIG. 3 is a block diagram showing a specific configuration of the camera control device according to the present invention. A power switch 50 in the figure is a main switch (the ON / OFF switch in FIG. 1C) for causing the camera 10 to function. The mode switch 26 is the switch shown in FIG. The photometric switch 24A and the release switch 24B
These switches are turned on when the release button 24 is half-pressed or fully pressed.

The remote control receiving circuit 52 is a circuit for detecting a remote control signal (ranging signal or release signal) by infrared rays emitted from the remote controller 40 based on a signal from an infrared sensor (not shown). This is a circuit for measuring the brightness of the subject based on the light incident on ten photometric windows 13 (see FIG. 1A).

The distance measuring circuit 56 includes a passive AF sensor 1
8 is a circuit for measuring a distance to a subject in each of a plurality of divided distance measurement areas based on a signal from an AF sensor (not shown) provided in 8. This circuit is
Functions as distance measuring means. The strobe circuit 58 is a circuit that causes the strobe light emitting section 22 (see FIG. 1A) of the camera 10 to emit light. AF auxiliary light projecting unit 20 ((A) in FIG. 1)
Is emitted by a signal from the CPU 100.

The focus lens driving circuit 60 is a circuit for rotating the focus motor 62 in accordance with the distance to the object measured by the distance measuring circuit 56 and driving the focus adjusting lens of the camera 10 to focus on the object. is there. The shutter drive circuit 64 is connected to the release switch S of the camera 10.
This circuit rotates the shutter motor 66 to release the shutter when the WR is turned on (when the release button is fully pressed) or when the release button 42 of the remote controller 40 is pressed. The focus lens driving circuit 60 functions as focusing means.

The green lamp 30 and the red lamp 32 are provided on the right side of the finder 28 of the camera 10 (see FIG. 1C). Is a lamp that functions as an indicator that indicates This lamp is turned on by a signal from the CPU 100.

The self-lamp 16 has a function as an indicator (FIG. 1) for displaying whether the measured subject distance is within the range of the remote control signal or outside the range.
(A). As schematically shown in FIG.
The distance to the subject measured by the distance measurement circuit 56 is
If the distance is farther than the reachable distance of the remote control signal sent from the remote controller, which is stored in advance in the EEPROM 102 (outside the reachable range of the remote control signal), it flashes or the distance to the subject measured by the distance measuring circuit 56 Lights when the distance is shorter than the reachable distance of the remote control signal sent from the remote control (within the range of the remote control signal reachable distance). The self-lamp 16 is also turned on and off according to a signal from the CPU 100.

The distance display lamp 23 is a lamp which is turned on during remote control photographing, and in this embodiment, comprises seven lamps. The distance display lamp 23 is a lamp whose lighting is controlled in accordance with the distance to the subject measured by the distance measuring circuit 56. In other words, it is a lamp that is turned on in accordance with the focusing distance to the subject (the lighting is turned on more when the focusing distance is longer). For example, it can be seen that when two distance display lamps are on, the focusing distance is shorter than when four distance display lamps are on.

In some cases, it is not possible to focus on the subject, but in such a case, all the distance display lamps 23 blink simultaneously. As a result, the person using the remote control can know that the camera is out of focus, and can perform remote control shooting without failure.
This lamp is also turned on by a signal from the CPU 100. The EEPROM 102 stores data such as which lamp should be turned on when the focusing distance is long, and the like.

As shown in FIG. 3, the CPU 100 inputs signals from all input devices (various sensors, switches, etc.) connected thereto and, based on a stored program, controls the connected individual devices. And controls the operation of output devices (such as various circuits and lamps), and functions as distance measuring means, focusing means, control means, and the like.

The schematic configuration of the camera control device according to the present invention is as described above. Next, the specific operation will be described in detail based on a flowchart. 4 and 5 are main flowcharts of the camera control device according to the present invention, and FIG. 6 is a flowchart showing a subroutine of the distance measurement process in the main flowchart of FIG. Note that these flowcharts are flowcharts processed in a mode in which the present invention functions, that is, in a state where the mode switch 26 is ON. Therefore, when the mode switch 26 is ON,
When the CPU 100 functions as control means and is turned off, it does not function as control means.

The photographing process shown by the main flowchart in FIG. 4 is started by half-pressing the release button 24 (turning on the photometric switch SWS) or half-pressing the push button 42 of the remote controller 40 (ranging operation). It is. When the flowchart of the photographing process starts, the photometric circuit 54 calculates the luminance of the subject based on a signal from the photometric sensor 53 that has received the subject light incident from the photometric window 13 of the camera 10 (S1). When the camera is set to the distant view mode (S2; Y), lens drive data (LL data) for moving the focusing lens group to the infinity in-focus position is set (S3), and the green lamp 30 is set. Is turned on (S4). By turning on the green lamp 30, the user can easily know that the distant view mode has been set while looking through the viewfinder 28.
When the distant view mode is selected as described above, the CP
U100 will no longer function as control means.

Next, AE calculation processing is performed to calculate the exposure amount of the subject (S14), a timer for measuring time is activated (S15), and a release signal (when the push button 42 is fully pressed) from the remote controller 40 Is not output, and the release switch SWR of the camera 10 is
If N has not been performed (S16; N), a release signal is output from the remote controller 40 or the release switch SWR is turned on until the time is up (S17;
N). When the time is up, the process exits this flowchart (S17; Y).

When a release signal is output from the remote controller 40 or the release switch SWR is turned on (S16;
Y), the CPU 100 turns off the green lamp 30 and the red lamp 32 and turns off the distance display lamp 23 (S1).
8) Perform exposure control processing. That is, the CPU 100
Moves the focus adjustment lens group through the focus lens drive circuit 60 and the focus motor 62 to focus on infinity, activates the shutter drive circuit 64 to move the shutter motor 66, and releases the shutter (S19). One film is wound up and the process returns (S20). If there is no remaining film in step S20, the entire film is rewound.

On the other hand, when the distant view mode is not set, a distance measuring process for measuring the distance to the subject is performed. The detailed processing of the distance measurement processing will be described with reference to the flowchart of FIG. 6, but the following processing is generally performed. That is, the closest distance measurement data is selected from the distance measurement data to the subject measured by the plurality of distance measurement areas, and is set as the distance to the subject (S5).

Next, in the processing in step S5,
If the distance to the subject could not be determined due to a failure in measuring the distance of the subject or the like and a distance measurement error occurred (S6; Y), the CPU 100 is disposed on the front of the camera 10. All of the displayed distance display lamps 23 are flashed simultaneously (S7). Thereby, the person using the remote controller can know that the camera is out of focus.

On the other hand, in the processing in step S5,
When the distance measurement of the subject is performed and no ranging error has occurred (S6; N), in the process in step S5, the distance to the subject regarded as the subject (ranging data).
However, it is determined whether the distance from the distance A to the distance G stored in the EEPROM 102 in advance as seven reference distances is larger or smaller.

If the distance measurement data is larger than the distance A, the distance display lamp A is turned on (S8, S9). If the distance measurement data is larger than the distance B, the distance display lamp B is turned on.
Is turned on (S10, S11), and a similar comparison is made. If the distance measurement data is larger than the distance G, the distance display lamp G is turned on (S12, S13). In other words, as the distance measurement data, that is, the distance to the subject or the focusing distance becomes longer, the number of lighting of the distance display lamp increases,
When the distance to the subject exceeds the distance G, all the distance display lamps are turned on. Thereby, the person using the remote controller can know the approximate focusing distance (the distance from the camera to the subject).

Next, AE calculation processing is performed to calculate the exposure amount of the subject (S14), a timer for measuring time is activated (S15), and a release signal (when the push button 42 is fully pressed) from the remote controller 40 Is not output and the release switch SWR is not turned on (S16; N), a release signal is output from the remote controller 40 until the time is up, or the release switch SWR is turned on. Wait for That is, the remote controller 40
When the push button 42 or the release button 24 is half-pressed, in other words, when the distance measurement signal is being output, the steps from S1 to S17 are repeatedly performed (S17).

When a release signal is output from the remote controller 40 or the release switch SWR is turned on (S16;
Y), the CPU 100 turns off the green lamp 30 and the red lamp 32 and turns off the distance display lamp 23 (S1).
8) Perform exposure control processing. That is, the CPU 100
Operates the focus lens drive circuit 60 based on the selected distance measurement data, moves the focus motor 62 to focus on the subject, activates the shutter drive circuit 64 to move the shutter motor 66, releases the shutter, and releases the film 1 Roll up. If there is no remaining film, the entire film is rewound (S19, S20).

Therefore, when photographing using the remote controller 40, the user of the remote controller can know the in-focus state and the out-of-focus state, and also know what the focusing distance is. It is possible to perform remote control shooting without failure.

Next, the distance measuring process in the main flowchart of FIG. 4 will be described with reference to the flowchart of FIG. The area measured through the passive AF sensor unit 18 is divided into, for example, six distance measurement areas, and the distance to the subject is independently recognized in each area. The luminance of the subject detected via the photometry window 13 is detected in each of a plurality of areas set so as to overlap the above-mentioned six distance measurement areas.

The CPU 100 reads preset setting data (emission data serving as a criterion for judging whether or not to perform auxiliary light emission from the AF auxiliary light emission unit 20) (S3).
1) Compare the setting data with the photometric value selected as the main (main photometric value) among the luminance of the subject detected in each of a plurality of areas (for example, two or three areas) and the setting data ( S32) If the main photometric value is larger than the set data, the brightness of the subject is sufficient for distance measurement, so that the auxiliary auxiliary light projecting unit 20 does not emit auxiliary light, and the main photometric value is smaller than the set data. if there is,
Auxiliary light is emitted from the AF auxiliary light emitting unit 20 (S33,
S34).

Next, the CPU 100 sets the value of the counter i to 0 (S35), and resets the AF sensor (S35).
36).

The CPU 100 sets a first ranging area among the above-described six ranging areas (S37), inputs sensor data of the area, and calculates a distance to the subject in the area (S38). , S39). The processing from S37 to S39 is performed for all ranging areas from the first ranging area to the sixth ranging area (S4).
0), the closest distance measurement data is selected from the distance measurement data to the object measured by the six distance measurement areas (S41).

Next, if the value of the counter 1 is 0 (S42), the CPU 100 increments the value of the counter i and sets it to 1 (S43). In the processing from S37 to S39, the first measurement is performed. If a ranging error occurs in all ranging areas from the ranging area to the sixth ranging area (the distance to the subject is not obtained), in other words, the ranging from the ranging area to the subject is not performed in any ranging area. If the distance is not determined (S44; Y), the AF auxiliary light projecting unit 20 emits auxiliary light (S45) and performs the processing from S36 to S42. That is, the distance to the subject is measured again by irradiating the auxiliary light.

In the first distance measurement (when i = 0), when the distance to the subject is determined in any of the distance measurement areas, or when the second distance measurement (when i = 1) is performed. If the distance to the subject has not been determined in all the distance measurement areas after the determination (S46; Y), a distance measurement error is set and the process returns to the main flowchart (S47).

On the other hand, when the distance to the subject is obtained in any of the distance measurement areas, the distance measurement data selected in step S41 is converted into lens drive data (LL data), and the CPU 100 drives the lens drive. The focus lens drive circuit 60 is operated based on the data, and the focus motor 62 is moved to focus on the subject.

In the above embodiment, the distance to the subject is displayed by the distance display lamp 23 having seven lamps, but the number of lamps may be eight or more or six or less. The arrangement is not limited to one row in the horizontal direction, but may be vertical or diagonal, or the lamps may be separated from each other.

[0042]

As is apparent from the above description, according to the first aspect of the present invention, when the distance measurement signal is output from the remote controller, the lighting of each distance display lamp is controlled according to the focusing distance of the subject. Therefore, when performing remote control shooting, it is possible to confirm that the person using the remote control is in focus. According to the second aspect of the present invention, the number of lighting of the distance display lamp is increased as the in-focus distance of the subject is increased. Can be known, and the distance to be focused can be adjusted while adjusting the standing position. According to the third aspect of the present invention, when the subject cannot be focused, all the distance display lamps are made to blink, so that the person using the remote control is out of focus. And you can shoot without mistakes. In the invention according to claim 4, a plurality of distance display lamps are arranged in a line in front of the camera body.
At a glance, the number of lights, the state of lighting, and the state of blinking can be confirmed.
