  The present invention relates to an imaging apparatus, an imaging control method, and a program including a light emitting unit that illuminates a subject.

  Conventionally, in an imaging apparatus such as a digital camera, when the imaging apparatus (self camera) and another imaging apparatus (other camera) capture the same subject synchronously, Japanese Patent Application Laid-Open No. 2003-324649 (Patent Document 1).

  However, in the technique of the above-mentioned Patent Document 1, regarding the light emission control at the time of synchronized shooting by a plurality of cameras, whether or not to emit light is determined according to the number of shots, or depending on whether or not charging is complete. Only the setting condition is determined, and no consideration is given to the influence of the light emission of one camera on the exposure condition on another camera, and the light emission may overlap due to synchronous shooting. In the above-mentioned Patent Documents 2 and 3, the influence of the light emission of one camera on the exposure condition given to another camera is considered, but the influence of each other is simply shifted by the shooting timing (light emission timing). I just lost it.

  An object of the present invention is to influence an exposure condition including a light emission condition of a plurality of imaging devices on an exposure condition that light emission of each imaging device gives to each other when the same subject is photographed synchronously with a plurality of imaging devices.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram showing an imaging system in which a plurality of imaging devices (cameras) are connected to each other in order to capture the same subject synchronously from different positions.
The imaging device (camera) is, for example, a compact digital camera or a single-lens reflex digital camera that uses a battery as a power source, and can capture still images as well as moving images. It has a synchronous photographing function for photographing synchronously.

  The illustrated example shows a state in which a plurality of (two) cameras perform synchronous shooting of the same subject (for example, a golfer who is practicing) from different positions. This is a case where two cameras are installed. That is, the case where the subject is synchronously photographed from the left oblique direction and the right oblique direction is shown. The camera A installed in the left oblique direction and the camera B installed in the right oblique direction have a master-slave relationship, and the shutter operation is performed. One of the performed cameras functions as a master-side camera, and the other camera functions as a slave-side camera.

  Camera A and camera B are connected for communication via short-range wireless communication, for example, wireless LAN (Local Area Network) or Bluetooth (registered trademark) communication. Camera A and camera B are connected via this short-range wireless communication. The synchronous shooting between the camera A and the camera B is controlled. By reproducing each image (still image or moving image) synchronously photographed by the camera A and camera B in synchronization with the same screen, the subject can be viewed in a multi-dimensional or three-dimensional manner. It is effective for analyzing golf forms. The flash emission function is, for example, a strobe (registered trademark) emission function that illuminates a subject by emitting an intense flash using an electronic flash as a light source. The flash emission function emits light in response to a user operation or the brightness of the subject. It is configured to automatically emit light. Note that the light source of the flash light emitting function is arbitrary, and it does not matter whether it is a built-in type or an external device type.

  In the first embodiment, when the same subject is synchronously photographed by a plurality of cameras, only the light emission of one camera is turned on (set to emit light) so that the light emission does not overlap on the subject. The light emission control is performed to turn off the light emission of other cameras (set to no light emission). For example, as shown in the figure, when the subject A is synchronously photographed from the left oblique direction and the right oblique direction, if the camera A and the camera B emit light at the same time, the light emission overlaps on the subject, and the light emission of one camera emits light. For example, when only the light emission of the camera A is turned on, the light emission of the camera B is turned off. On the contrary, only the light emission of the camera B is turned on. In such a case, the light emission control for turning off the light emission of the camera B is performed.

FIG. 2 is a block diagram illustrating basic components of the imaging apparatus (camera).
The control unit 1 operates by supplying power from the power source unit (secondary battery) 2 and has a central processing unit, a memory, and the like that control the overall operation of the camera according to various programs in the storage unit 3. ing. The power supply unit 2 is a main body power source that supplies power to the camera body (the control unit 1, the storage unit 3, and the like). The storage unit 3 has a configuration including, for example, a ROM, a flash memory, and the like, and a program memory in which a program and various applications for realizing the present embodiment are stored according to an operation procedure illustrated in FIG. 3a.

  Furthermore, the storage unit 3 records and saves a work memory 3b that temporarily stores various types of information (for example, information such as counter values and flags) necessary for the operation of the camera, and each captured image. It has an image memory 3c and the like. The storage unit 3 may include a removable portable memory (recording medium) such as an SD card or an IC card, and is connected to a network via a communication function (not shown). The state may include a storage area on a predetermined server device side. The control unit 1 is connected with an operation unit 4, a display unit 5, an imaging unit 6, a wireless communication unit 7, a flash light emitting unit 8, an electronic compass 9 and the like as its input / output devices, and controls their input / output operations. . The electronic azimuth meter 9 will be described in other embodiments described later.

  Although not shown, the operation unit 4 switches between an operation mode (shooting mode) in which shooting can be performed and an operation mode (playback mode) in which a captured image (saved image) is played back. In addition to the mode change button for switching to the synchronous shooting mode of the camera and the shutter button for instructing the start of shooting, various shooting parameters such as shutter speed, aperture, ISO sensitivity, flash emission, zoom magnification, focus, etc. It has buttons to set. The control unit 1 performs, for example, a mode change process, a shooting control process, a shooting parameter setting process, and the like as a process according to the input operation signal from the operation unit 4. The display unit 5 is a high-definition liquid crystal display or an organic EL (Electro Luminescence) display, and serves as a monitor screen (live view screen) for displaying a captured image (live view image) or a playback screen for reproducing a captured image. It becomes.

  The imaging unit 6 constitutes a camera unit that can photograph a subject with high definition. The lens unit 6A includes a zoom lens 6B, a focus lens (focusing lens) 6C, an aperture / shutter 6D, and an imaging device (CCD or CCD). CMOS) 6E. The imaging unit 6 drives the zoom lens 6B, the focus lens 6C, and the aperture / shutter 6D in accordance with a control signal from the control unit 1 to perform zoom adjustment, focus adjustment, automatic exposure adjustment (AE), and start / end of shooting. I try to control it. This automatic exposure adjustment (AE) process is a process of automatically determining the presence or absence of flash light emission and exposure conditions (shutter speed, aperture, ISO sensitivity) other than the light emission by measuring the brightness of the subject. When a subject image from an optical lens system such as the zoom lens 6B and the focus lens 6C is formed on the image sensor 6E, an image signal (analog value signal) read out by photoelectric conversion is converted into digital value data. The image is converted and displayed on the display unit 5 in real time as a live view image.

  The flash light emitting unit 8 constitutes the above-described flash light emitting function, and is configured to illuminate a subject by emitting intense flash light using an electronic flash as a light source. When the same subject is photographed synchronously by a plurality of cameras, the control unit 1 acquires a light emission condition automatically determined by automatic exposure adjustment (AE) on the other camera side, and according to the acquired light emission condition. Thus, control (readjustment) is performed to change again the exposure condition automatically determined by automatic exposure adjustment (AE) on the own camera side. In this case, of the cameras A and B, the flash emission on one camera side is turned on (set to have light emission) and the flash emission on the other camera side is turned off (set to have no light emission). The light emission does not overlap. Note that the exposure conditions of the own camera include a flash emission condition on the own camera side (in the first embodiment, whether light is emitted) and other exposure conditions (shutter speed, aperture, ISO sensitivity) other than the emission. I mean.

  Next, the operation concept of the camera in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. The same applies to other embodiments described later. In addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium. FIG. 3 is a flowchart showing an outline of the operation of the characteristic part of the present embodiment in the overall operation of the camera. When the flow of FIG. 3 is exited, the main flow of the overall operation (not shown). Return to.

FIG. 3 shows a synchronous shooting mode that is started when a menu item of “synchronous shooting” by a plurality of cameras is selected and designated from the menu screen in a state where various shooting modes are displayed as menus. It is the flowchart which showed the operation | movement of each camera.
First, the control unit 1 of each camera (for example, camera A and camera B) performs processing (step A1) for initializing predetermined information and the like, and then performs a half-shutter operation (release) as a two-step push-in shutter operation. It is checked whether half-pressing operation (one-step pressing operation) has been performed (step A2).

  Here, when the half-shutter operation is performed (YES in step A2), a radiographing preparation instruction signal (signal for instructing execution of an imaging preparatory process such as automatic focus adjustment and automatic exposure adjustment) is sent from the wireless communication unit 7 to the other. Although wireless transmission is performed to the camera (step A3), if the half shutter operation is not performed (NO in step A2), it is checked whether a shooting preparation signal is received from another camera via the wireless communication unit 7 (step A4). . In this case, the camera on which the shutter operation has been performed functions as a master-side camera, and the camera that receives a shooting preparation signal from the master camera functions as a slave-side camera.

  When a half shutter operation is performed (YES in step A2), or when a shooting preparation signal is received from another camera (YES in step A4), automatic focus adjustment (AF) is started (step A5). , Automatic exposure adjustment (AE) processing that automatically determines the presence / absence of flash emission (on / off) and other exposure conditions (shutter speed, aperture, ISO sensitivity) by measuring the brightness of the subject. Processing for determining camera exposure conditions (including flash emission) is performed (step A6).

  Then, the light emitting condition (presence / absence of light emission) of the own camera determined as described above is wirelessly transmitted from the wireless communication unit 7 to another camera (step A7). That is, the light emission condition transmission process is performed in order to adjust the light emission condition automatically determined on the other camera side according to the light emission condition of the own camera. Next, it is checked whether or not “with light emission” is received as the light emission condition on the other camera side (step A8). Here, if “flash emission” is not received from another camera (NO in step A8), that is, if the flash is not emitted on the other camera side, whether or not the flash is emitted on the own camera side is determined. Regardless, the process proceeds to the next step A10. When “with light emission” is received from another camera (YES in step A8), an exposure condition redetermination process (step A9) is executed in order to consider the influence of light emission by the other camera. Thereafter, the process proceeds to the next step A10, where it is checked whether or not a full shutter operation (release full-press operation) has been performed.

FIG. 4 is a flowchart for explaining the exposure condition redetermination process (step A9 in FIG. 3) in detail.
First, the control unit 1 checks whether or not the light emission condition on the own camera side is “with light emission (light emission on)” (step B1), and when it is “no light emission (light emission off)” (NO in step B1). Since the overlap of the light emission does not occur even if the synchronous shooting is performed, the exposure condition redetermination process in FIG. 4 is skipped. However, in the case of “with light emission” (YES in Step B1), the overlap of the light emission by the synchronous shooting is performed. Therefore, the process proceeds to the next step B2, and it is checked in advance whether or not the own camera is designated as the priority camera.

  Here, the priority camera refers to which camera, for example, the camera installed near the front of the subject is set as the priority camera when the flash of the camera and other cameras overlaps during synchronous shooting. The camera is arbitrarily set in advance by user operation (predetermined key operation on the operation unit 4) with priority on the side light emission. If the current camera is the priority camera (NO in step B2), the process exits the flow of FIG. 4 in order to validate the “with light emission” on the own camera side, but the own camera is not the priority camera ( “YES” at step B2), “with light emission” on the camera side is determined again as “without light emission” (step B3). In this case, since the other camera (priority camera) emits light, other exposure conditions (shutter speed, aperture, ISO sensitivity) other than the light emission determined in step A5 in FIG. And

  When the exposure condition redetermination process (step A9) is completed, the process proceeds to the next step A10 to check whether the full shutter operation has been performed. If the full shutter operation has been performed (YES in step A10 in FIG. 3). ) The wireless communication unit 7 wirelessly transmits a shooting start instruction signal for instructing the timing of synchronous shooting to another camera (step A11), but if the full shutter operation is not performed (NO in step A10), the other camera It is checked whether or not an imaging start instruction signal has been received via the wireless communication unit 7 (step A12). Here, when a full shutter operation is performed (YES in step A10), or when a shooting start instruction signal is received from another camera (YES in step A12), flash control and shooting processing are executed. In the case of “with light emission” on the camera side, the flash light emitting unit 8 is activated to emit the flash, and when shooting is performed with shooting parameters set according to other exposure conditions other than the light emission, After the captured image is acquired and subjected to processing such as development and image compression, it is recorded and stored in the image memory 3c (step A13).

  As described above, in the first embodiment, the control unit 1 acquires the automatically determined light emission condition on the other camera side when the same subject is photographed synchronously with a plurality of cameras, and the acquired light emission condition is acquired. The exposure conditions automatically determined by the camera itself are controlled accordingly, so the exposure conditions including the flash conditions of multiple cameras are adjusted to take into account the effects on the exposure conditions that each camera's flash emits to each other. Therefore, the subject can be photographed synchronously under appropriate exposure conditions. In this case, even if the captured images of each camera are reproduced in synchronization, each image is captured with an appropriate exposure considering the influence of mutual light emission. For example, the golf form should be analyzed accurately. Is possible.

  The own camera acquires the lighting conditions automatically determined by the other cameras when performing synchronous shooting, and adjusts the exposure conditions determined by the own camera according to the acquired lighting conditions of the other cameras. Since the exposure conditions automatically determined on the other camera side are adjusted by sending the lighting conditions determined by the own camera to the other cameras, the influence of the light emitted by the other cameras between each camera Can be adjusted.

  When the camera's own camera and the other camera's lighting conditions are both flashing, the flashing condition on the camera's own side has been changed from "flashing" to "no flashing". Illumination is performed by flash emission from one camera, and overlapping of flash emission on the subject can be prevented.

  When the camera's own camera and other cameras also emit light, the camera determines whether to give priority to the camera or to give priority to the other camera. Since the condition is changed to “no light emission”, the user can select in advance which camera has priority.

  In the first embodiment described above, when the light emission conditions on the own camera and the other camera side are “with light emission”, the light emission condition on the own camera side is changed to “no light emission”. Control to change the light emission condition on the camera side to “no light emission” may be performed. In this case, when the own camera side is the priority camera, it is only necessary to transmit a light emission presence / absence change signal instructing other cameras to change from “with light emission” to “without light emission”. Even in this case, the own camera functions as a master and the other cameras function as slaves.

  In the first embodiment described above, which of the own camera and the other camera is selected as the priority camera is selected and specified in advance by a user operation. For example, the electronic azimuth meter 9 is used to approximately A camera facing the side may be specified, and the specified camera may be set as the priority camera. In this case, by comparing the photographing direction (azimuth) of the camera with respect to the subject measured by the electronic azimuth meter 9 with a predetermined front direction (azimuth) of the subject, the direction is directed substantially to the front side of the subject. What is necessary is just to specify a camera.

  In the first embodiment described above, the case of performing synchronous shooting with two cameras has been exemplified. However, when synchronous shooting is performed with three or more cameras, basically, synchronous shooting with two cameras is used. Similarly, if the own camera is a priority camera, only the own camera may be controlled to be “with light emission”.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
Note that in the first embodiment described above, when the same subject is synchronously photographed by a plurality of cameras, the light emission that turns off only the light emission of one camera in order to prevent the light emission from overlapping on the subject. In this second embodiment, when the light emission from a plurality of cameras overlaps on the subject, the light emission conditions (the presence / absence of light emission, the amount of light emission) are controlled, or other exposure is performed. The conditions (shutter speed, aperture, ISO sensitivity) are controlled. Further, in the first embodiment described above, although not particularly mentioned, in the second embodiment, the arrangement state of the own camera and the other camera with respect to the subject is specified, and the own camera is determined according to the arrangement state. The exposure condition is adjusted, and the distance from the own camera to the subject and the distance from the other camera to the subject are specified as the arrangement state of the own camera and the other camera with respect to the subject. Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

5 and 6 show the operation of each camera that is started when the “synchronous shooting” menu item is selected and designated, as in FIG. 3 (the operation outline of the characteristic part of the second embodiment). It is a flowchart.
First, the control unit 1 of each camera (for example, camera A and camera B) performs an initialization process (step C1 in FIG. 5) as in the first embodiment in FIG. Processing such as clearing the value of a counter (not shown) is also performed. Thereafter, the presence / absence of the half shutter operation is checked (step C2). When the half shutter operation is performed (YES in step C2), an imaging preparation signal is wirelessly transmitted to another camera (step C3). If not (NO in step C2), it is checked whether a shooting preparation signal has been received from another camera (step C4).

  When the half shutter operation is performed (YES in step C2), or when a shooting preparation signal is received from another camera (YES in step C4), automatic focus adjustment (AF) is started (step C5). This automatic focus adjustment process includes a process of measuring the distance from the camera to the subject. Next, a process for measuring the brightness of the subject and automatically determining the presence or absence of flash emission (on / off) and other exposure conditions (shutter speed, aperture, ISO sensitivity) according to the measured value (Step C6). Then, the determined light emission condition (presence / absence of light emission) of the own camera is wirelessly transmitted to another camera (step C7).

  Next, the flow proceeds to the flow of FIG. 6, and it is checked whether or not “with light emission” is received as the exposure condition on the other camera side (step C8). Here, if “flash emission” is not received from another camera, the process proceeds to the next step C16 regardless of whether or not the flash is emitted on the own camera side, and a full shutter operation (release full-press operation) is performed. However, when “with light emission” is received from another camera (YES in step C8), the process proceeds to execution of an exposure condition redetermination process in order to consider the influence of light emission by the other camera (step S8). C9).

FIG. 7 is a flowchart for explaining the exposure condition redetermination process (step C9 in FIG. 6) in detail.
First, the control unit 1 acquires the brightness of the subject measured by the exposure condition determination process (step C6 in FIG. 5) on the own camera side (step D1), and the automatic focus adjustment process (step C5 in FIG. 5). The distance to the subject measured by is acquired (step D2). Then, the light emission amount of the own camera and the distance to the subject are transmitted / received to / from other cameras (step D3). Based on the received light emission amount of the other camera and the distance from the subject to the other camera, the brightness increase amount (brightness change) on the subject due to the light emission of the other camera side is calculated (step D4). In this case, the larger the light emission amount of the other camera and the closer the distance from the subject to the other camera, the greater the brightness increase amount on the subject due to the light emission of the other camera.

  Then, it is checked whether or not the light emission on the own camera side is necessary with the brightness taking into account the brightness increase amount on the subject by the light emission on the other camera side (step D5). In this case, if the brightness of the subject measured by the camera and the brightness increase by the light emission of the other camera is not sufficient as the brightness at the time of shooting by the camera, Although it is determined that the light emission is necessary, if the brightness including the brightness increase amount is sufficient, it is determined that the light emission on the own camera side is not necessary.

  If light emission on the own camera side is required (YES in step D5), the light emission condition on the own camera side is set to “with light emission” (step D6), and according to the distance from the own camera to the subject. Then, the degree of influence on the exposure condition on the own camera side is obtained, and a process of changing the light emission amount of the own camera in accordance with the degree of influence and redetermining is performed (step D7). In this case, the light emission amount is reduced as the distance to the subject is shorter. Furthermore, the degree of influence on the exposure condition on the own camera side is obtained based on the brightness change on the subject due to light emission of the own camera and the other camera, and other exposure conditions other than the light emission in the own camera are determined according to the degree of influence. A process of changing (shutter speed, aperture, ISO sensitivity) and redetermining is performed (step D8). In this case, as the amount of light emitted from the other camera is larger, the distance from the subject to the other camera is closer, or the distance from the subject to the own camera is closer, the brightness change of the subject due to light emission from the other camera side is more likely. The degree of influence is obtained so that the degree of influence on the exposure condition on the camera side becomes high, and the larger the degree of influence, the other exposure conditions other than light emission are changed in a direction of darkening and redetermined. Thereafter, the flow of FIG.

  On the other hand, when light emission on the own camera side is not required (NO in step D5), the light emission condition on the own camera side is set to “no light emission” (step D9), and the subject caused by light emission of another camera is set. Based on the above brightness change, a process for changing again the exposure conditions (shutter speed, aperture, ISO sensitivity) other than the light emission in the own camera is performed (step D10). Thereafter, the flow of FIG.

  When such an exposure condition redetermination process (step C9 in FIG. 5) ends, “1” is added to the above-described number counter that counts the number of executions of the exposure condition redetermination process, and the value is updated. (Step C10). In this case, since the value of the number counter is initialized to “0” before the exposure condition redetermination process is executed, the value is updated to “1” in the first exposure condition redetermination process. Next, it is checked whether or not the light emission condition of the camera itself has changed due to the execution of the above exposure condition redetermination process (step C11). If the light emission condition has not changed (NO in step C11), the process proceeds to step C13, and others. Check if the changed lighting conditions were received from the camera. Further, when there is a change in the light emission condition of the own camera (YES in step C11), a process of transmitting the changed light emission condition of the own camera to another camera (step C12) is performed, and then the process proceeds to step C14. It is checked whether the value of the number counter is greater than or equal to the maximum value (for example, “3”).

  If the light emission condition after change is not received from another camera (NO in step C13), the process proceeds to step C16 to check whether or not a full shutter operation (release full-press operation) has been performed. When the changed light emission condition is received from the camera (YES in step C13), the process proceeds to step C14, and it is checked whether or not the value of the above-mentioned number counter is not less than the maximum value (for example, “3”). If it is less than the maximum value (NO in step C14), the process returns to step C9 described above, and the exposure condition redetermination process is executed again. By this re-execution, “1” is added to the above-mentioned number counter and the value is updated to “2” (step C10). Even if this second exposure condition redetermination process is executed, the light emission condition of the camera itself Is changed (YES in step C11), or when the light emission conditions of other cameras are changed (YES in step C13), the condition is that the number counter value is less than the maximum value “3” (step NO at C14), the process returns to step C9 described above, and the exposure condition redetermination process is executed again (step C9).

  By repeatedly executing the exposure condition redetermination process in this manner, when it is detected that the light emission condition of the own camera does not change (NO in step C11) and the light emission conditions of other cameras do not change (step C13). NO), the process proceeds to step C16 to check whether or not the full shutter operation has been performed. Now, when a full shutter operation is performed (YES in step C16), after performing processing (step C17) for wirelessly transmitting a shooting start instruction signal for instructing the timing of synchronous shooting from the wireless communication unit 7 to another camera. Then, the process proceeds to flash control and photographing processing (step C18).

  If the full shutter operation is not performed (NO in step C16), it is checked whether a shooting start instruction signal is received from another camera via the wireless communication unit 7 (step C19). If a shooting start instruction signal is received (YES in step C19), the flash control is performed on the condition that a shooting timing delay signal (described later) has not been received from another camera (NO in step C20). Then, the process proceeds to the photographing process (step C18). This flash control and photographing process (step C18) activates the flash light emitting unit 8 and emits the flash with the light emission amount determined according to the distance to the subject when “flash light emission is present” on the own camera side. After that, the image captured with the imaging parameters set according to the exposure conditions other than the light emission is acquired, subjected to development processing and image compression processing, and recorded and stored in the image memory 3c.

  On the other hand, if the above-mentioned number counter value is equal to or greater than the maximum value “3” (YES in step C14), a radiographing timing delay signal is wirelessly transmitted to another camera (step C15). This shooting timing delay signal indicates the shooting timing of the other camera until a predetermined delay time (for example, a time until the influence of the afterglow of the flash is eliminated (for example, 0.1 second) from the shooting timing of the camera itself. Here, when a shooting start instruction signal is received from another camera (YES in step C19), it is checked whether a shooting timing delay signal has been received from the other camera (step S19). C20) If the delay signal has been received (YES in step C20), the process waits until a delay time (for example, 0.1 second) elapses (step C21), and when the elapsed time of the delay time is detected. (YES in step C21), the process proceeds to the above-described flash control and photographing process (step C18).

  As described above, in the second embodiment, when the control unit 1 performs the adjustment to change the light emission condition of the own camera according to the light emission condition on the other camera side, the changed light emission condition is changed to another one. By sending to the camera, the exposure conditions on the other cameras are adjusted again according to the changed lighting conditions, so that the influence of the light emission of each camera on the mutual exposure conditions must be taken into account. The exposure conditions on each camera side can be set to an appropriate state.

  When adjustment is made to change the lighting conditions on the other camera according to the lighting conditions on the own camera side, the changed lighting conditions are received again from the other camera. The camera's exposure conditions are adjusted again according to the camera's lighting conditions, so that the effects of each camera's light emission on each other's exposure conditions can be taken into account. Can be set to an appropriate state.

  If you change the lighting conditions on your camera according to the lighting conditions on the other camera, send the changed lighting conditions to the other camera again. If the camera's exposure conditions are adjusted again and the flash conditions on the other camera are changed according to the flash conditions on the camera's own camera side, the changed flash conditions are received again from the other camera. Therefore, the operation to adjust the exposure conditions on the own camera side again according to the lighting conditions on the other camera side after the change is repeated until the lighting conditions on the own camera side and the other camera side are not changed. The exposure conditions on each camera side can be finely adjusted as precisely as possible.

  Count the number of repetitions of readjustment of exposure conditions, and if the lighting conditions are changed even if the count reaches a predetermined value, shift the shooting timing between the camera and the other camera. Even if the exposure conditions on each camera side cannot be finely adjusted, it is possible to prevent overlapping of light emission on the subject by shifting (delaying) the shooting timing. .

  The flash emission conditions include the presence / absence of flash emission and the amount of light emitted, and the exposure conditions on the own camera side are adjusted according to the amount of light emitted on the other camera side. Even if they overlap each other, it is possible to adjust to an appropriate exposure condition in consideration of the light emission amount on the other camera side.

  Since the camera and other camera's placement status with respect to the subject is specified and the exposure conditions of the camera are adjusted according to this placement status, the influence on the mutual exposure conditions depending on the placement status of each camera In addition, it is possible to adjust to an appropriate exposure condition.

  The arrangement state of the own camera and other cameras with respect to the subject is the distance from the subject to the own camera and other cameras, and the exposure condition of the own camera is adjusted according to this distance. Therefore, it is possible to adjust to an appropriate exposure condition.

  Based on the amount of light emitted from the other camera, the distance from the subject to the other camera, and the distance from the subject to the camera, the change in brightness on the subject determines the degree of influence on the exposure conditions on the camera. Since the exposure conditions of the camera itself are adjusted according to the degree of influence, other exposure conditions (shutters other than the light emission of the camera itself) depending on the light emission amount on the other camera side and the distance from the subject to the other camera (Speed, aperture, ISO sensitivity) can be adjusted, and the light emission amount of the camera can be adjusted according to the distance from the camera to the subject. In this case, the greater the amount of light emitted by the other camera, the closer the distance from the subject to the other camera, the closer the distance from the subject to the camera, The degree of influence is obtained so that the degree of influence of the camera increases, and the larger the degree of influence, the darker the exposure condition of the camera is adjusted.

  In the second embodiment described above, when light emission on the own camera side is required (YES in step D5 in FIG. 7), the light emission amount on the own camera side is determined again according to the distance from the own camera to the subject. (Step D7), or another exposure condition other than the light emission in the own camera is re-determined based on the brightness change on the subject due to the light emission of the own camera and the other camera (step D8). Alternatively, only re-determination of the light emission amount on the own camera side may be re-determined, or only other exposure conditions other than light emission may be re-determined. Furthermore, even if the light emission level is changed and re-determined, if it is not possible to cope with it only by adjusting the light emission level, the exposure condition other than the light emission can be changed and re-determined. Even if the redevelopment is changed and redetermined, the light emission amount may be changed and redetermined if it cannot be dealt with only by adjusting the exposure conditions.

  In the second embodiment described above, the case of performing synchronous shooting with two cameras has been exemplified. However, when synchronous shooting is performed with three or more cameras, basically, synchronous shooting with two cameras is used. It is the same. In this case, since there are two or more other cameras with respect to the own camera, the distance to the subject is obtained for each of the other cameras, and the total amount of increase is calculated from the brightness increase amount on the subject. You can do it.

(Third embodiment)
A third embodiment of the present invention will be described below with reference to FIGS.
In the second embodiment described above, the distance from the camera to the subject and the distance from the other camera to the subject are measured and specified as the arrangement state of the camera and the other camera with respect to the subject. In the third embodiment, as the arrangement state of the own camera and the other camera with respect to the subject, the direction (azimuth) of the own camera with respect to the subject and the direction (azimuth) of the other camera are measured in addition to the distance to the subject. I try to identify. Here, in the first embodiment and the third embodiment, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the characteristic portions of the third embodiment will be mainly described below. It shall be explained in

FIG. 8 is a diagram for explaining an opening angle (azimuth angle) between the own camera and another camera with respect to a subject.
The electronic azimuth meter 9 measures the direction of the own camera with respect to the subject in response to the above-described half shutter operation or shooting preparation signal. The control unit 1 receives and acquires the orientation of the subject measured on the other camera side, and obtains the opening angle (azimuth angle) θ between the own camera and the other camera from the orientation of the own camera and the orientation of the other camera. Based on the opening angle (azimuth angle) θ, the exposure condition of the own camera is determined again. The controller 1 does not need to accurately determine the opening angle (azimuth angle) θ. For example, the control unit 1 specifies 16 directions from the directions measured by the electronic azimuth meter 9, and roughly determines the opening angle ( The azimuth angle θ is obtained. In the illustrated example, if the direction of the camera A is “south-southwest” and the direction of the other camera B is “east”, the opening angle (azimuth angle) θ with respect to the direction of the camera A is defined as each camera A, The opening angle of B (approximately 110 °) is obtained. In the drawing, La represents the distance from the subject to the camera A, and Lb represents the distance from the subject to the camera B.

FIG. 9 is a flowchart for explaining in detail the exposure condition redetermination process (step C9 in FIG. 6) in the third embodiment. In the third embodiment, the operation at the time of synchronous shooting is the same as that in FIG.
First, the control unit 1 obtains the orientation with respect to the subject measured by the electronic azimuth meter 9 (step E1), and the subject measured by the exposure condition determination process on the own camera side (step C6 in FIG. 5 described above). (Step E2), and the distance from the camera to the subject measured by the automatic focus adjustment process (step C5 in FIG. 5 described above) is acquired (step E3). Then, a process of transmitting and receiving the light emission amount of the own camera, the direction to the subject, and the distance to the subject to and from other cameras is performed (step E4).

  Then, an opening angle (azimuth angle) θ of each camera is obtained based on the azimuth of the own camera and the azimuth of the other camera (step E5), and the received light emission amount of the other camera, the azimuth of the other camera, and the subject Based on the distance from the camera to the other camera, a brightness increase amount (brightness change) on the subject is calculated by light emission on the other camera side (step E6). In this case, as the light emission amount of the other camera is larger, the distance from the subject to the other camera is closer, the opening angle (azimuth angle) θ of each camera is smaller, the brightness on the subject due to the light emission of the other camera is reduced. The amount of increase will be large.

  Similarly to the case of the second embodiment (FIG. 7), whether or not light emission on the own camera side is necessary with brightness that takes into account the brightness increase amount on the subject by light emission on the other camera side. (Step E7). As a result, when light emission on the own camera side is required (YES in step E7), the light emission condition on the self camera side is set to “with light emission” (step E8), and the distance from the camera to the subject is set. Accordingly, the degree of influence on the exposure condition on the own camera side is obtained, and a process of changing the light emission amount of the own camera in accordance with the degree of influence and redetermining is performed (step E9). Furthermore, the degree of influence on the exposure condition on the own camera side is obtained based on the brightness change on the subject due to light emission of the own camera and the other camera, and other exposure conditions other than the light emission in the own camera are determined according to the degree of influence. A process of changing (shutter speed, aperture, ISO sensitivity) and redetermining is performed (step E10). Thereafter, the flow of FIG. 9 is exited.

  On the other hand, when light emission on the own camera side is not required (NO in step E7), the light emission condition on the own camera side is set to “no light emission” (step E11), and the subject caused by light emission of another camera is set. Based on the above brightness change, a process of changing again the exposure conditions (shutter speed, aperture, ISO sensitivity) other than the light emission in the own camera is performed (step E12). Thereafter, the flow of FIG. 9 is exited.

  As described above, in the third embodiment, the arrangement state of the own camera and the other camera with respect to the subject is the direction (orientation) of the own camera and the other camera with respect to the subject, and the direction of the own camera and the other camera ( Since the exposure condition of the own camera is adjusted according to the (azimuth), it is possible to adjust the exposure condition from the azimuth (direction) of each camera to an appropriate exposure condition.

  The brightness change on the subject determines the degree of influence on the exposure condition on the own camera side according to the amount of light emitted on the other camera side, the opening angle formed by the direction of the own camera and the direction of the other camera. Since the exposure condition of the camera itself is adjusted according to the degree of influence, the light emission of the camera itself depends on the amount of light emitted from the other camera and the opening angle formed by the camera orientation relative to the subject and the camera orientation. Other exposure conditions (shutter speed, aperture, ISO sensitivity) can be adjusted, and the light emission amount of the own camera can be adjusted. In this case, the greater the amount of light emitted by the other camera, the smaller the opening angle formed by the direction of the camera and the direction of the camera, and the degree of influence of the brightness change on the subject on the exposure conditions on the camera The degree of influence is obtained so that the exposure is higher, and the exposure condition of the own camera is adjusted to be darker as the degree of influence is larger.

  In the third embodiment described above, the opening angle is obtained from the direction of the own camera and the direction of the other camera. However, the opening angle between the cameras is not limited to the direction, and each camera is arranged. You may make it obtain | require from the position which exists. For example, a GPS (Global Positioning System) positioning unit (not shown) may be provided, and an opening angle between the cameras may be obtained from position information (longitude / latitude information) measured by the GPS positioning unit. Furthermore, an arrangement state of each camera may be specified by analyzing an image captured by each camera, and an opening angle between the cameras may be obtained from the arrangement state.

  In the third embodiment described above, the case of performing synchronous shooting with two cameras has been exemplified. However, when synchronous shooting is performed with three or more cameras, basically, synchronous shooting with two cameras is used. It is the same. In this case, since there are two or more other cameras with respect to the own camera, the direction with respect to the subject is obtained for each other camera to obtain the opening angle with the own camera, and the brightness increase amount on the subject is also increased. What is necessary is just to obtain | require the total amount of increase for the number from the brightness increase amount for this number.

  Also in the third embodiment described above, the light emission amount on the own camera side is re-determined, and other exposure conditions other than the light emission are re-determined, but the light emission amount on the own camera side is re-determined. Only the exposure condition other than the light emission may be determined again. Furthermore, even if the light emission level is changed and re-determined, if it is not possible to cope with it only by adjusting the light emission level, the exposure condition other than the light emission can be changed and re-determined. Even if the redevelopment is changed and redetermined, the light emission amount may be changed and redetermined if it cannot be dealt with only by adjusting the exposure conditions.

  In the second and third embodiments described above, the light emission amount on the other camera side may be a value corresponding to the specification of the light source of the flash, but the other camera side actually emitted light toward the subject. At this time, the light emission amount on the other camera side may be calculated from the brightness change on the subject. This makes it possible to know the degree of influence of the light emission of the other camera on the exposure condition of the own camera without measuring the distance from the other camera to the subject or measuring the direction with respect to the subject.

  In each of the above-described embodiments, the light emission condition automatically determined by the other camera is received and acquired. However, the light emission condition acquired first from the other camera is arbitrarily manually operated by the user operation on the other camera side. It may be set. In addition, the light emission condition may be acquired from another camera before the exposure condition is automatically determined by the automatic exposure adjustment (AE) process.

  In each of the above-described embodiments, a case where the present invention is applied to a digital camera has been described. However, the present invention is not limited to this, and a mobile phone such as a personal computer with a camera function, a PDA (personal portable information communication device), a tablet terminal device, or a smartphone. -An electronic game or a music player may be used.

  Further, the “apparatus” and “unit” shown in each of the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.
