  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a perspective view of the camera 100 as viewed obliquely from the front. The camera 100 includes a front and rear thin cubic housing 151, a lens barrel 153 and a light emitting window 155 disposed on the front surface of the housing 151, a release button 152 disposed on the upper surface of the housing 151, a power switch 154, An operation unit 156 is provided.

  The lens barrel 153 holds an optical system that forms a subject image on an image sensor disposed inside the housing 151. The light emission window 155 illuminates the subject by generating a flash according to an instruction from a photographing control unit described later.

  The release button 152 enables a focus detection sensor, a photometric sensor, and the like, which will be described later, when the user half-presses. As a result, the camera 100 prepares for shooting a subject image. When the release button 152 is fully pressed, the shutter is opened and a subject image is taken. In addition, the light emission window 155 may generate a flash in accordance with the shooting timing.

  The power switch 154 intermittently operates the entire camera 100 each time it is pressed by the user. The operation unit 156 includes other buttons, levers, and dial type switches. In this drawing, a seesaw lever type zoom switch appears.

  FIG. 2 is a perspective view of the camera 100 as viewed obliquely from the rear. Elements that are the same as those in FIG. 1 are given the same reference numerals, and redundant descriptions are omitted.

  An operation unit 156 including a plurality of switches and a rear display unit 212 are arranged on the rear surface of the housing 151. The operation unit 156 is operated when various settings are input to the camera 100, when the operation mode of the camera 100 is switched, or when changing the magnification of the lens barrel or the like in real time. The rear display unit 212 is formed of a liquid crystal display panel or the like, and occupies many areas on the rear surface of the casing 151.

  When the camera 100 as described above is in the shooting mode, the subject image incident on the lens barrel 153 is continuously photoelectrically converted by the image sensor and displayed on the rear display unit 212 as a through image. The user can know the effective shooting range by observing the through image displayed on the rear display unit 212. The rear display unit 212 also displays the state of the camera 100 such as the remaining battery level and the remaining capacity of the storage medium. Further, when the camera 100 operates in the playback mode, a playback image is displayed on the rear display unit 212.

  FIG. 3 is a block diagram schematically showing the functional structure of the camera 100. Elements common to those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted. The camera 100 includes a control unit 201, an imaging unit 202, an audio processing unit 203, and a communication unit 204.

  The control unit 201 includes a CPU 190, a display driving unit 210, an attitude sensor 220, a program memory 230, and a main memory 240. The CPU 190 comprehensively controls the operation of the camera 100 using the main memory 240 as a work area.

  Further, the CPU 190 forms a photographing control unit 192 according to firmware. The imaging control unit 192 changes the imaging magnification, the focal position, the aperture opening, the shutter speed, the sensitivity of the image sensor 112, and the like in the camera 100. In addition, an image is displayed on the rear display unit 212 through the display driving unit 210.

  The display driving unit 210 generates a display image according to an instruction from the CPU 190 and displays it on the rear display unit 212. Further, the image displayed on the rear display unit 212 is rotated according to the posture of the camera 100 detected by the posture sensor 220. Thereby, even when the camera 100 is in the vertical position, an upright image can be observed on the rear display unit 212.

  The imaging unit 202 includes an imaging element driving circuit 110, an imaging element 112, an analog / digital conversion circuit 120, an image processing circuit 130, a secondary storage medium 132, a contrast autofocus circuit 140, and a photometric sensor 150. As the imaging element 112, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), or the like can be used.

  The image sensor driving circuit 110 drives the image sensor 112 to convert the subject image formed on the surface of the image sensor 112 into an electric signal. The output signal of the image sensor 112 is discretized by the analog / digital conversion circuit 120 and converted into captured image data by the image processing circuit 130. The image processing circuit 130 adjusts the white balance, sharpness, gamma, gradation correction, compression, and the like of the image in the process of generating captured image data.

  The captured image data generated by the image processing circuit 130 is stored in a secondary storage medium 132 such as a flash memory card. At least a part of the secondary storage medium 132 can be attached to and detached from the camera 100.

  The contrast autofocus circuit 140 determines that the lens barrel 153 is in focus when the contrast of the image is the highest in the focus area of the through image generated for the purpose of displaying on the rear display unit 212. The contrast autofocus circuit 140 is also used when shooting a moving image with the camera 100.

  The audio processing unit 203 includes a microphone 260 and a speaker 270. The microphone 260 is used when recording audio together with video during moving image shooting. Moreover, it is used also when recording a user's voice as a voice memo. The speaker 270 generates an operation sound, a warning sound, and the like when the camera 100 operates. It is also used when playing back moving images shot with sound.

  Communication unit 204 includes a transmission unit 170 and a reception unit 180. The transmission unit 170 converts the data into a wireless signal in response to an instruction from the CPU 190 and transmits the data. The receiving unit 180 receives a radio signal, demodulates data included in the radio signal, and transmits the demodulated data to the CPU 190.

  The camera 100 includes an input unit 160 and a magnification driving unit 250 in addition to the control unit 201, the imaging unit 202, the sound processing unit 203, and the communication unit 204. When the release button 152, the power switch 154, the operation unit 156, or the like is operated, the input unit 160 transmits an operation instruction corresponding to the operation to the CPU 190. Further, the setting value input from the user through the operation unit 156 is held.

  The magnification changing unit 250 moves a part of the optical system of the lens barrel 153 according to an instruction from the CPU 190. As a result, the magnification of the lens barrel 153 changes, and the angle of view of the captured image changes.

  FIG. 4 is a block diagram schematically showing a functional structure of the photographing assisting device 300. As shown in FIG. The imaging assistance apparatus 300 includes a communication unit 301, a CPU 310, a program memory 340, a main memory 350, a storage unit 360, a photometric sensor 370, and a camera position detection unit 380.

  The communication unit 301 includes a reception unit 320 and a transmission unit 330 and can exchange data with the communication unit 204 of the camera 100. The CPU 310 executes processing using the main memory 350 as a work area according to the firmware read from the program memory 340. As a result, the CPU 310 also operates as the calculation unit 312.

  The storage unit 360 stores auxiliary shooting information that is referred to when the calculation unit 312 calculates shooting conditions. The imaging assistance information stores an image of what is likely to be a subject in the place where the imaging assistance apparatus 300 is installed. Further, the photographing assistance information also stores light source information in a photographing environment where the photographing assistance apparatus 300 is installed. Further, the storage unit 360 may acquire and store information such as weather and date / time of the shooting environment through communication with the outside.

  The photometric sensor 370 includes a spectrophotometer that performs spectroscopic measurement of incident light in an imaging environment in which the imaging assistance apparatus 300 is installed, an illuminometer that detects the illuminance of a subject or a building, and the like. These photometric sensors 370 are different from small ones that can be built in the camera 100 and can perform precise measurements at high speed. Note that a plurality of light receiving units of the photometric sensor 370 may be arranged in the shooting environment of the shooting assistance device 300 and linked to the shooting assistance device 300.

  The camera position detection unit 380 detects the position of the camera 100 in the shooting environment where the shooting assistance device 300 is installed. The position of the camera 100 is detected by a method of detecting a light emitting element, a barcode, a QR code (Quick Response code: a registered trademark of Denso Wave Co., Ltd.), an RFID (Radio Frequency IDentification) tag, etc. An indoor positioning method using radio waves such as a wireless LAN or IMES (Indoor Messaging System) may be used.

  FIG. 5 is a diagram illustrating the positional relationship between the camera 100 and the photographing assisting device 300 in the building 410 of the gymnasium. The main floor 411 in which a competition or the like is performed inside the building 410 is illuminated by a plurality of lighting fixtures 422 suspended from the ceiling. In addition, a lighting window 412 and a catwalk 414 are provided on the side wall of the building 410. Further, a small room 413 illuminated by another lighting device 424 is provided near the entrance of the building 410.

  The photographing assisting device 300 is installed at a high side wall in the indoor 401 of the building 410. On the other hand, the photographers 442, 444, 446, and 448 holding the camera 100 shoot from various positions such as the outdoor 402 of the building 410, the main floor 411, the inside of the small room 413, and the catwalk 414. .

  The subject to be photographed by the photographers 442, 444, 446, and 448 is not limited to the player 430 playing a game on the main floor 411. The player 430 may be photographed at a place other than the main floor 411, or the building 410 itself, the scenery of the outdoor 402, or the like may be photographed. Therefore, the photographing environment related to the photographing assisting device 300 includes the outdoor 402 around the building 410 as long as the communication unit 204 of the camera 100 and the communication unit 301 of the photographing assisting device 300 can communicate with each other.

  FIG. 6 is a flowchart mainly showing an operation procedure of the transmission unit 170 in the communication unit 204. When the camera 100 is activated, the CPU 190 of the camera 100 first checks whether the operation mode is the shooting mode or the playback mode (step S101).

  When the operation mode of the camera 100 is the playback mode (step S101: NO), the CPU 190 causes the communication unit 204 to wait as it is because communication with the imaging assistance apparatus 300 is unnecessary. When the operation mode of the camera 100 is the shooting mode (step S101: YES), the CPU 190 activates the communication unit 204 to establish communication with the shooting assisting apparatus 300 (step S102).

  Subsequently, the CPU 190 executes initial communication with the imaging assistance device 300 (step S103). In the initial communication, the photographing auxiliary device 300 is notified of the function, performance, individual identification information, and the like of the camera 100. Thereafter, the CPU 190 waits until the release button 152 is half-pressed and photographing with the camera 100 is started (step S104: NO).

  When the release button 152 is pressed halfway in the camera 100 (step S104: YES), the CPU 190 extracts the last frame from the through image captured by the image sensor 112 and captures it as a pre-captured image (CPU 105). Next, the captured preliminary photographed image is transmitted to the photographing assisting apparatus 300 as specific information (step S106). Therefore, the specific information includes a subject to be photographed.

  Further, the CPU 190 confirms whether or not the received auxiliary photographed image is received by the auxiliary photographing device 300 by checking whether or not the reception confirmation transmitted from the auxiliary photographing device 300 has been received (step S107). Here, when the reception confirmation from the imaging assistance apparatus 300 has not been received after a certain time has elapsed (step S107: NO), the CPU 190 attempts to retransmit the preliminary captured image. When the reception confirmation by the photographing assistance device 300 is received (step S107: YES), the CPU 190 waits until the release button 152 is half-pressed again.

  Note that the specific information transmitted from the camera 100 to the photographing assistance device 300 is not limited to the image extracted from the through image. The specific information may be an image captured separately as a pre-captured image, or may be information of an EXIF (EXCHANGE IMAGE FORMAT FORMAT) file format including shooting condition information in the camera 100 or a part thereof, as will be described later. May be.

  FIG. 7 is a flowchart showing the execution procedure of processing in the imaging assistance apparatus 300. When the camera 100 enters the range in which the communication unit 301 can communicate, the imaging assistance device 300 requests the camera 100 to start communication and establishes communication (step S201).

  When communication with the camera 100 is established, the imaging assistance device 300 performs initial communication with the camera 100 (step S202). In the initial communication, in addition to the identification information of the model and the individual of the camera 100, the performance and function of the camera 100 are transmitted to the photographing assisting device 300. Thereby, the imaging assistance device 300 can provide imaging conditions that can be executed by the camera 100.

  Subsequently, the photographing assistance apparatus 300 waits until the camera 100 starts photographing and the release button 152 is half-pressed (step S203: NO). When the release button 152 of the camera 100 is half-pressed (step S203: YES), since the specific information is transmitted from the camera 100, the photographing assisting apparatus 300 acquires the specific information (step S204). The imaging assistance apparatus 300 that has acquired the valid specific information returns a reception confirmation to the camera 100 (step S205). Thereby, the imaging assistance device 300 can detect the imaging target of the camera 100.

  FIG. 8 is a diagram illustrating an example of the preliminary photographed image 501 acquired by the photographing assisting device 300. The pre-photographed image 501 reflects one corner of the main floor 411 in the indoor 401 of the building 410.

  Since the entrance to the small room 413 is reflected in the preliminary image 501, the corner of the main floor 411 is reflected, and the player 430 is looked down, the preliminary image 501 is shown in FIG. 5, the image is taken from the position of the photographer 448 standing on the catwalk 414.

  The auxiliary photographing apparatus 300 matches the pre-photographed image 501 as described above with a known video in the photographing environment stored in the storage unit 360. Thereby, the imaging assistance apparatus 300 can know what imaging object the camera 100 is suitable for. Furthermore, the distance between the camera 100 and the subject can be calculated from the position of the camera 100 detected by the camera position detection unit 380. Furthermore, the magnification set in the lens barrel 153 of the camera 100 can be calculated. As described above, the specifying information includes information that can be used when specifying the current position of the camera 100.

  FIG. 9 is a diagram illustrating an example of another preliminary photographed image 502 acquired by the photographing assisting device 300. The pre-captured image 502 reflects the outer wall of the small room 413 of the building 410 and the entrance / exit of the small room 413 from the outdoor 402. The photographing assisting apparatus 300 that has acquired the preliminary photographed image 502 matches the known video in the photographing environment stored in the storage unit 360 stored in the storage unit 360. Thereby, the imaging assistance apparatus 300 can know what imaging object the camera 100 is suitable for.

  Further, the photographing assisting device 300 uses the camera position information detected by the camera position detecting unit 380 in the calculation unit 312 and the size and shape of the small room 413 reflected in the preliminary photographed image 502 to determine the position and direction of the camera 100. Then, the magnification and the like are calculated, and the optimum shooting conditions for shooting the subject outdoors 402 are calculated. Thus, the shooting conditions calculated by the shooting assistance device 300 may include both indoor shooting conditions and outdoor shooting conditions.

  Referring to FIG. 7 again, the calculation unit 312 of the imaging assistance apparatus 300 detects imaging related information including the imaging object of the camera 100 from known imaging assistance information regarding the shape and the like of the building 410 read from the storage unit 360 ( Step S206). Subsequently, the calculation unit 312 calculates shooting conditions suitable for the camera 100 based on the detected shooting-related information (step S207).

  Here, for example, a high pressure mercury lamp, a metal halide lamp, a high pressure sodium lamp, or the like is used as the lighting fixture 422 that illuminates the main floor 411 of the gymnasium. These luminaires 422 have a unique spectral distribution different from any of sunlight, tungsten lamps and fluorescent lamps. Therefore, depending on the auto white balance function of the camera 100, an appropriate white balance may not be obtained.

  However, the photographing assisting apparatus 300 reads out information about the characteristics and usage state of the lighting fixture 422 in the building 410 in which the photographing assisting apparatus 300 is installed from the storage unit 360 and grasps the information. Therefore, the calculation unit 312 can provide the camera 100 with white balance adapted to the lighting fixture 422 as a shooting condition. Further, when the subject to be photographed by the photographer 444 moves to the small room 413, a white balance suitable for the lighting fixture 424 is provided as a photographing condition.

  Furthermore, the imaging assistance apparatus 300 reads out the position and area of the daylighting window 412 and the position of the sun 450 according to the time from the storage unit 360 and grasps it. Therefore, an appropriate white balance can be calculated even in a state where the lighting fixture 422 and the light of the sun 450 are mixed. As described above, the shooting conditions provided to the camera 100 by the shooting assistance device 300 may include ambient light information of a shooting environment including white balance information.

  Still further, the photographing assisting device 300 grasps the position of the camera 100 by the camera position detection unit 380 and thickens it. Therefore, the contrast search range of the contrast autofocus circuit 140 can be limited by calculating the distance between the photographers 442, 444, 446, and 448 and the subject. Thereby, the camera 100 can be focused at high speed.

  In addition, for example, when the lighting apparatus 422 is directly reflected when the camera 100 widens the shooting angle of view, shooting information for limiting the zooming range in the camera 100 may be transmitted to the camera 100. As described above, the shooting conditions provided by the shooting assistance device 300 may include at least one of the shooting angle of view and the focal length.

  In this way, the CPU 310 transmits the shooting conditions calculated by the calculation unit 312 from the transmission unit 330 to the reception unit 180 of the camera 100 (step S208). Thereby, the camera 100 can acquire the optimal shooting condition in the building 410 and perform shooting under the shooting condition.

  Note that when the imaging condition is transmitted to the camera 100, the imaging assistance apparatus 300 confirms reception of the imaging condition by receiving a reception confirmation from the communication unit 204 of the camera 100 (step S209). If reception is confirmed, the imaging assistance device 300 ends a series of imaging assistance and waits (step S208: YES). If the reception of the imaging conditions cannot be confirmed (step S209: NO), the imaging auxiliary device 300 tries to transmit the imaging conditions again (step S207).

  When the shooting conditions are thus provided to the camera 100, the shooting assistance device 300 checks whether communication with the camera 100 continues (step S210). When the power of the camera 100 is turned off or when the camera 100 is moved out of the shooting environment of the shooting assistance device 300, communication between the shooting assistance device 300 and the camera 100 is interrupted (step S210: NO). The imaging assistance device 300 cancels imaging assistance for the camera 100.

  When the communication with the camera 100 is continued (step S210: YES), the photographing auxiliary device 300 waits until the release button 152 of the camera 100 is next half-pressed and the next specific information is transmitted (step S210). S203: NO). When release button 152 is half-pressed on camera 100 (step S203: YES), new specific information is transmitted from camera 100. Therefore, the imaging assistance device 300 starts imaging assistance again from the stage of acquiring the specific information (step S204).

  Note that the imaging assistance device 300 may increase the accuracy of the imaging conditions to be calculated with reference to the shade information, weather information, and the like acquired from the storage unit 360. In addition, the imaging assistance device 300 may acquire imaging information when the camera 100 captures a preliminary imaging image and use it for calculation of imaging conditions.

  FIG. 10 is a diagram illustrating a structure of an image file 500 generated when an image is captured by the camera 100. The image file 500 stores main image data 510, thumbnail image data 520, and tag data 530.

  The main image data 510 corresponds to captured image data captured by the imaging unit 202 of the camera 100. On the other hand, the thumbnail image data 520 has a lower resolution, color depth, and the like than the main image data 510. This facilitates handling when displaying a list of a plurality of main image data 510 stored by the camera 100 or the like.

  The tag data 530 stores specifications of the camera 100 that captured the main image data 510, imaging conditions, and the like. When the JPEG (Joint Photographic Experts Group) format is adopted as the file format of the image data 510, the image file with tag data includes information defined as an EXIF file.

  More specifically, in addition to basic information such as the manufacturer, specifications, firmware version number, open F value, etc. of the camera 100 that captured the main image data 510, the exposure time, F value, ISO value, focal length at the time of shooting Shooting information such as shooting date and time is recorded. Furthermore, for example, when the camera 100 has an additional function such as a GPS function, the GPS information of the place where the image was taken may be added to the tag data 530.

  In the camera 100, the tag data 530 is generated when the release button 152 is half-pressed and the photographing condition is fixed. In the camera 100, when the release button 152 is pressed halfway down to full press, the generated tag data 530 is stored in the image file 500 together with the main image data 510.

  At this point, when the release button is pressed halfway down and the last frame of the through image is a pre-captured image, tag data 530 is attached to the pre-captured image and shooting assistance is performed in a format compliant with the EXIF file. You may transmit to the apparatus 300. FIG. Accordingly, the calculation unit 312 can calculate the shooting condition more precisely with reference to the shooting condition calculated by another method. Further, by comparing the photographing condition calculated on the photographing auxiliary apparatus 300 side with the photographing condition included in the tag data 530, the reliability of the photographing condition calculated by the photographing auxiliary apparatus 300 can be increased.

  FIG. 11 is a flowchart mainly showing an operation procedure of the receiving unit 180 in the communication unit 204. The receiving unit 180 stands by until receiving a shooting condition from the transmission unit 330 of the shooting assisting apparatus 300 (step S301: NO).

  When the receiving unit 180 receives the shooting condition (step S301: YES), the CPU 190 checks whether or not the received shooting condition includes a prohibition item that restricts shooting (step S302). When the prohibited items are not included (step S302: NO), the shooting conditions are transferred to the shooting control unit 192 and reflected in shooting by the imaging unit 202 (step S303).

  If the received shooting condition includes a prohibited item (step S302: YES), the CPU 190 checks whether or not the prohibited item prohibits shooting itself (step S304). Here, when the prohibition item prohibits photographing itself (step S304: YES), the CPU 190 displays on the rear display unit 212 that photographing is prohibited in the photographing environment, and controls related to photographing. Exit. Alternatively, the power supply of the camera 100 may be forcibly shut off.

  When the prohibited item is not prohibition of photographing itself but prohibition of flash emission by the light emission window 155 (step S304: NO), the CPU 190 changes the operation mode of the camera 100 corresponding to the prohibition item. (Step S305). Thereby, the camera 100 enters, for example, a light emission inhibition mode.

  Thus, after the camera 100 responds to the prohibited items, the shooting conditions are transferred to the shooting control unit 192 within a range where the prohibited items can be avoided (step S303). As described above, the photographing assisting apparatus 300 can automatically prohibit the prohibited items for the camera 100.

  Note that when the photographing assistance device 300 transmits photographing prohibition, image information that has already been photographed in the photographing environment may be provided to the camera 100. Accordingly, an image of the shooting environment can be provided to the user instead of forcing the shooting prohibition.

  FIG. 12 is a flowchart illustrating an operation procedure of the imaging control unit 192 in the camera 100. The imaging control unit 192 to which the imaging conditions are transferred from the receiving unit 180 checks whether there are any overlapping condition items in the transferred imaging conditions (step S401).

  When the transferred shooting conditions have one value for each of items such as white balance, exposure time, aperture opening, etc. (step S401: YES), the imaging unit 202 is controlled according to the shooting conditions, and shooting is performed. (Step S402). However, when the transferred shooting conditions include, for example, two shooting conditions related to white balance (step S401: NO), the shooting control unit 192 sets the shooting condition value to one (step S403).

  In this case, a plurality of methods for combining a plurality of values can be exemplified. For example, there is a method of selecting one from a plurality of values. That is, by comparing the shooting conditions calculated by the camera 100 itself with the shooting conditions received from the shooting assistance device 300, one that is close to the shooting conditions of the camera 100 itself can be selected.

  Another method is to process a plurality of values together and calculate a new value. For example, a single value can be obtained by taking an average value of a plurality of values.
