  Further, the camera body CPU 27 performs an AF operation by controlling the operation of the focus lens constituting the photographing lens 3 according to the output of the focus detection sensor 11 in cooperation with the lens CPU 7. Furthermore, the camera body CPU 27 stores the state (focal length) of the zoom lens constituting the photographing lens 3 and information on the photographing lens 3 itself (for example, lens types such as a wide-angle lens, a telephoto lens, a macro lens, etc.). Can be obtained through.

  As described above, the photometric sensor 15 measures the luminance distribution of the object scene by measuring the luminous flux incident on the photographing lens 3 for each of a plurality of areas, and outputs the measurement result to the camera body CPU 27.

Yes. Further, the user guide for guiding the user with respect to the functions provided in the camera system 1 is also classified into a plurality of types according to the type, and is managed in a hierarchical manner in a tree structure within each category. Yes. Further, the flash ROM 29 stores a usage history for a predetermined number of times of the menu setting screen and the user guide screen. The flash ROM 29 stores map information, and the camera body CPU 27 obtains current position information from latitude, longitude, altitude information obtained as an output of the GPS module 16 and map information stored in the flash ROM 29. Can be acquired.

  The RAM 30 is a high-speed RAM such as a DRAM in which a program stored in the flash ROM 29 is expanded and the camera body CPU 27 can access at high speed. In particular, various adjustment values and setting values that are frequently referred to are also copied from the flash ROM 29 to facilitate access from the camera body CPU 27.

  The rear monitor control circuit 28 performs display control for displaying the menu setting screen and the user guide screen read from the flash ROM 29 on the rear monitor 21 in addition to the image processed as described above. Further, a touch panel sensor is stacked on the surface of the rear monitor 21, and when the user operates the touch panel sensor while visually recognizing the menu items of the rear monitor 21, the coordinates and the coordinates are displayed.

  The attitude sensor 22 is an attitude detection unit that detects the attitude of the camera system 1 as described above. The posture sensor 22 is configured by combining a sensor that detects the posture in a uniaxial direction depending on whether a small sphere moving due to gravity blocks the infrared light of the photo interrupter. When it is desired to detect an accurate angle as the posture of the camera system 1, a triaxial acceleration sensor or the like is used. In particular, in the present embodiment, any configuration may be used as long as it is detected whether the user is in the forward tilt posture in which the user can easily view the rear monitor 21.

  The tripod determination unit 35 is a holding state detection unit that determines whether or not the camera body 2 is attached to a tripod and detects the holding state. The tripod determination unit 35 outputs the angular velocity sensor 6 and the camera body 2. Whether the camera body 2 is in the tripod fixed state is determined from the sensor switch etc. of the tripod fixed position.

  The event information acquisition unit 31 is an event detection unit that detects and acquires event information held at a specific facility via a network. The event information acquisition unit 31 includes a network connection unit such as a wireless LAN (not shown) and a program that acquires event information in a specific facility from the network. Note that the event information acquisition unit 31 is not limited to accessing information published on the network, but may be configured to access a database related to event information constructed in advance by the user. Further, the event information acquisition unit 31 can be internally configured so that the user accesses a database stored in the flash ROM 29 as schedule information, for example, instead of being connected to a network.

  The release SW 32 is a two-stage switch. When the user half-presses the release SW 32, shooting preparation operations such as autofocus and photometry are performed. Further, when the user fully presses the release SW 32, the camera body CPU 27 starts a still image / moving image shooting operation.

  The flash control circuit 52 of the flash device 50 controls the light emission amount and the light emission time of each color light emitting diode 51 (R-LED, G-LED, B-LED) in cooperation with a camera body CPU 27 described later. At this time, the camera body CPU 27 controls the entire camera system 1 in cooperation with the lens CPU 7 and the flash device 50.

  The photographing operation of the camera system 1 configured as described above will be described below along the flowchart of FIG. This flowchart is assumed to be in a state where a power supply (not shown) is turned on. Also, this flowchart is as described above. It is assumed that the camera body CPU 27 executes the program stored in the flash ROM 29 and developed in the RAM 30. That is, based on this flowchart, the camera body CPU 27 captures an image using the information on the photographing lens 3 and the environment information from the environment detection unit including the GPS module 16, the microphone 17, the calendar unit 38, the pyroelectric sensor 36, and the like. It operates as a setting unit for setting (shooting assist).

  The camera body CPU 27 acquires information on the taking lens 3 (step S1). In the present embodiment, the camera body CPU 27 acquires focal length information of the photographing lens 3 and confirms that the macro lens has a focal length of 60 mm, for example. Note that the information on the photographing lens 3 may be acquired at the timing when the photographing lens 3 is attached to the camera body 2.

  Next, the camera body CPU 27 acquires environment information (step S2). In the present embodiment, the camera body CPU 27 acquires the current position information from the latitude, longitude, altitude information obtained as the output of the GPS module 16 and the map information stored in the flash ROM 29, and from the calendar unit 38 the season Get date and time information such as month, time. In addition, when the positioning by the GPS module 16 is impossible, such as when indoors, the current position information may be estimated from the position information acquired when the positioning is possible. The camera main body CPU 27 detects event information (event content, event start time, event end time) at the current position and its surroundings from the event information acquisition unit 31. Further, the camera body CPU 27 performs voice identification on the voice input by the microphone 17 by the voice identification unit 34, and as described above, the input voice is classified or input as a child voice, a pet cry, or the like. Perform voice word recognition.

  The camera body CPU 27 does not have to acquire all the information described above, and may acquire information that can be used for shooting assistance as appropriate.

  The camera body CPU 27 acquires environmental information such as position information, date and time information, event information, and audio information as described above, and determines whether or not shooting assistance is possible based on the information of the shooting lens 3 acquired in step S1. (Step S3). Specifically, the camera body CPU 27 acquires the event information regarding the aquarium from the event information acquisition unit 31 from the event information acquisition unit 31 where the information of the photographing lens 3 acquired in step S1 is a macro lens, the position information acquired in step S2 is an aquarium. In this case, it is determined that the user performs macro shooting in the aquarium, it is determined that shooting assistance is possible, and the process proceeds to step S4. Here, whether or not the camera system 1 is in the aquarium building can be determined to be in the building when positioning by the GPS module 16 is not possible, for example.

  In step S4, the camera main body CPU 27 executes assist for macro shooting in the aquarium. Specifically, the camera body CPU 27 sets flash photography prohibition because flash photography is prohibited in an aquarium, sets the ISO sensitivity between 800 and 1600, and photographs organisms in the water. Therefore, set the white balance to underwater (specify the blue band correction to underwater). Further, since the aquarium is generally dark, the camera body CPU 27 sets the aperture 5 near the open position and performs an AF operation based on the output of the focus detection sensor 11 in order to perform AF in the phase difference method. In addition to this, the camera main body CPU 27 sets a continuous AF mode in which AF is continuously executed because shooting of moving objects is expected.

  In addition, when the user selects moving image shooting, the camera body CPU 27 does not perform aperture control because the attached lens is a macro lens. Furthermore, the camera body CPU 27 changes the exposure value calculated from the output of the photometric sensor 15 when it is determined from the output of the photometric sensor 15 that the backlight is in a backlit state (a state where the user is surrounded by a water tank). At the same time, gradation correction is performed on the obtained image (this process is also called “active D lighting”).

  In addition, the camera body CPU 27 prohibits flash photography in step S4 as the photography of the caterpillar when the information acquired in step S2 is photographing outdoors (suburbs) in the summer night.

  The camera body CPU 27 determines whether or not the release SW 32 is fully pressed in step S5. If the release SW 32 is fully pressed, the camera main body CPU 27 performs shooting in step S6 and ends this flowchart. The camera body CPU 27 repeats step S5 when the release SW 32 is not fully pressed, but may end this flowchart when the release SW 32 is not fully pressed for a predetermined time.

  On the other hand, the camera body CPU 27 proceeds to step S7 when there is insufficient information for assisting shooting in step S3. An example of when there is not enough information to assist shooting is when shooting a macro object during the daytime outdoors, such as shooting a moving object such as a child or a pet, or a stationary subject such as a flower. It may not be possible to determine whether to shoot. Even if the voice identification unit 34 identifies a pet cry from the voice collected by the microphone 17 in step S2, it is not necessarily a macro photography of the pet.

  For this reason, the camera body CPU 27 obtains information regarding the posture of the camera (step S7). Specifically, the camera body CPU 27 detects the posture of the camera system 1 from the posture sensor 22. In addition to this, the camera body CPU 27 may confirm whether or not a tripod is attached to the camera system 1 from the tripod determination unit 35.

  The camera body CPU 27 determines again whether or not shooting assistance is possible (step S8). The camera main body CPU 27 determines whether or not the posture of the camera system 1 is tilted forward from the posture sensor 22, and when the camera system 1 is tilted forward with the release SW 32 being pressed halfway, a stationary flower or the like in the field. It is determined that the subject is a subject, and it is determined that shooting assistance is possible. In this case, if the tripod determination unit 35 detects that a tripod is attached to the camera system 1, it is possible to recognize the shooting situation with higher accuracy.

  If the camera body CPU 27 determines in step S8 that shooting assistance is possible based on the environmental information currently acquired, in step S4, the camera body CPU 27 executes assistance in shooting flowers outdoors. Specifically, the camera body CPU 27 sets the aperture priority mode (set the aperture yourself, set the shutter speed to the brightness, and set the blur condition during macro shooting). The description of subsequent steps S5 and S6 is the same as that described above, and will be omitted.

  On the other hand, when the camera body CPU 27 determines again that the assist shooting is not possible only with the environmental information currently acquired in step S8, the process proceeds to step S9 and determines whether it is the shooting timing. If the release SW 32 is half-pressed, the camera body CPU 27 determines that it is the shooting timing, and performs the processing from step S5. On the other hand, if the camera body CPU 27 determines in step S9 that it is not the shooting timing, the process proceeds to step S10.

  Step S10 is not a shooting timing, and assumes a scene where the user seems to have time. Therefore, the camera body CPU 27 confirms the shooting scene with the user (inquires the user) in step S10. Specifically, the camera body CPU 27 generates a beep sound from the speaker 18 to alert the user, and displays a photographing scene confirmation mode (inquiry mode) on the rear monitor 21 as shown in FIG. For example, the camera body CPU 27 captures the daytime shooting outdoors using a macro lens from the environmental information acquired in steps S1, S2, and S7, and the voice identification unit 34 outputs a child's voice and pet's voice. In the case of identification, a display for inquiring whether to photograph a child or a pet is performed. The user can select whether to photograph a child or a pet by operating the cross switch 33. Note that, instead of the operation of the cross switch 33, either shooting may be selected by operating the touch panel sensor.

  Note that the camera main body CPU 27 ends this flowchart if the user does not show interest in the confirmation mode when there is no selection operation by the user for a predetermined time. Similarly, the camera main body CPU 27 also ends this flowchart when the user presses the release SW 32 halfway.

  The camera main body CPU 27 proceeds to step S4 when the user's photographing target can be confirmed in the confirmation mode in step S10, and executes photographing assistance. For example, when photographing of a pet is selected by the user, the camera main body CPU 27 sets the AF area for executing AF to a single point AF mode in which only one point is set, and causes the user to select an AF area. This is for focusing on the eyes of the dog, not on the nose of the dog nearby, when photographing a pet such as a dog. In addition, when shooting of the child is selected by the user, it is expected that the child moves fast because of shooting of the child outdoors. For this reason, the camera body CPU 27 prohibits flash photography and increases the shutter speed. The camera body CPU 27 sets continuous shooting and sets AF to multipoint AF.

[Modification]
In the above description, as shooting assistance executed by the camera body CPU 27, when the macro lens is attached, the camera body CPU 27 uses the environment information including information on the macro lens and various sensors and registered information. Although the case where the current situation is determined and shooting assistance suitable for the situation has been described, the shooting assistance according to the present embodiment is not limited to this description.

  For example, the camera body CPU 27 detects the moving speed from the information regarding the position acquired by the GPS module 16 in the determination of the photographing assist in steps S3 and S8, and when the moving speed is faster than a predetermined value, the camera system 1 It is determined that the vehicle is in a moving means such as a train or a car. If the camera body CPU 27 determines that the camera body is in the moving means, the camera shake correction sensitivity (or control mode) based on the detected value of the angular velocity sensor 6 is suitable for shooting in the moving means in step S4. Set to change to mode. At this time, if the position information acquired by the GPS module 16 and the map information stored in the flash ROM 29 are compared, and it is determined that the current position is on the track or on the road, it is determined that the user is in the moving means. Can be improved.

  Further, when the camera body CPU 27 compares the position information acquired by the GPS module 16 with the map information stored in the flash ROM 29 and determines that the camera body CPU 27 is at or near the sea, information on the attached photographic lens 3 is obtained. The information from the attitude sensor 22 and the angular velocity sensor 6 can be used to determine that the camera system 1 is in the sea. For example, a macro lens or a wide lens is attached as the photographic lens 3, vibration that continues at a constant cycle is detected by the angular velocity sensor 6, and the camera body 2 is detected by the attitude sensor 22 when the release SW 32 is half-pressed. Can be determined to be underwater (underwater) shooting. As described above, when it is determined that the shooting is underwater, the camera body CPU 27 sets the white balance to a mode suitable for shooting underwater or sets the shutter speed faster, for example. At this time, the camera body CPU 27 determines which area the sea is in, and acquires the weather information around the current position by the event information acquisition unit 31 via the network, so that the current area and the weather at that time can be obtained. Can be set for white balance and shutter speed. Alternatively, it is possible to determine the current season based on information from the calendar unit 38 and to perform shooting assistance suitable for the season.

  The sensor for acquiring the environmental information is not limited to a sensor built in or attached to the camera system 1, and an external sensor that can communicate with the camera body CPU 27 by a communication means (not shown) may be used. Is possible. For example, it is also possible to acquire information on the current depth or whether or not the subject is in the water by communication from a depth gauge worn by the diver, and perform the above-described photographing assist. The current position information can be configured not only to use the information of the GPS module 16 but also to directly specify (input) the photographer using the rear monitor 21 and the cross SW 33 (or touch panel).

  In addition, the camera system 1 is provided with a pyroelectric sensor (infrared detector) 36 connected to the camera main body CPU 27, and the camera main body CPU 27 has a movement like a child or a dog as a subject to be photographed now. It can also be configured to determine whether there is no movement like a plant. In this case, the pyroelectric sensor 36 has its detection area set in the field of view of the photographic lens 3 attached to the camera body 2 and detects infrared rays from an object in at least a part of the object field of the photographic lens 3. To do. As described above, the method of detecting the infrared rays emitted from the child or dog by the pyroelectric sensor 36 and performing the shooting assist is particularly effective when a macro lens for shooting a subject at a short distance is attached to the camera body 2. is there.

  In the camera system 1, when the camera body CPU 27 determines that the telephoto lens is attached to the camera body 2, the camera body CPU 27 assists in changing the camera shake correction mode. For example, the camera main body CPU 27 determines whether or not the camera main body 2 is fixed to the tripod by the tripod determination unit 35, and if it is fixed, the camera shake correction mode is corrected to the shake on the mechanism. If it is not fixed, it is set to correct hand shake. Further, when the release SW 32 is half-pressed, the camera body CPU 27 determines whether the zoom lens of the photographic lens (telephoto lens) 3 is on the telephoto side or the wide-angle side. Is set to be high and low when it is on the wide angle side.

  Further, when the camera system 1 is configured to be able to shoot a moving image in addition to a still image, the camera system 1 can be configured to set a camera shake correction mode according to the situation. For example, when determining that the camera body CPU 27 is in the still image shooting mode, the camera body CPU 27 is set to perform camera shake correction in consideration of high-frequency components among the shakes detected by the angular velocity sensor 6, and is in the moving image shooting mode. If it is determined, the camera shake correction is not performed or only the camera shake correction for the low frequency component is performed. In the case of moving image shooting, the sound at that time is stored in addition to the image, so that the operation sound due to camera shake correction is not recorded. Similarly, since the operation sound is generated when the aperture is controlled, it can be set so that the aperture is not controlled in moving image shooting.

  In the above-described embodiment, the camera system 1 which is a lens interchangeable single-lens reflex camera has been described as an example. However, the present invention can also be applied to a mirrorless single-lens camera in which the main mirror 10 and the pentaprism 14 are omitted. Also, in a camera system (compact camera, etc.) in which the lens cannot be exchanged, the same as when the above-mentioned macro lens, wide lens, and telephoto lens are attached by using the focal length and installation information of the lens.
