  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a concept of an advice screen displayed to a photographer by the advice display device of the present embodiment. In the advice screen of the present embodiment, the photographing equipment and the photographing settings are presented not in independent but in a combined condition.

  In the advice screen, the combined conditions are arranged on a two-dimensional coordinate in which the horizontal axis represents the burden of photographing settings and the vertical axis represents the burden of photographing equipment. On the vertical axis, the burden of the shooting equipment (purchase cost) increases as the cost increases. Photography equipment includes interchangeable lenses, flashes, and tripods.

  As for the degree of burden of shooting setting on the horizontal axis, the operation load after setting or setting becomes higher as going to the right. Note that specific photographing equipment and photographing settings are selected and displayed according to the photographing environment. That is, not all shooting equipment and shooting settings are displayed regardless of the subject. Here, the display is simplified by vertical and horizontal biaxial display so that it can be easily expressed on a general display panel. Of course, when a large panel or 3D panel is adopted, there may be an application in which the operation burden is further divided into three axes by dividing the operation burden into time burden and labor burden.

  Each square area is an area that indicates a combination condition of photographing equipment and photographing settings. AC1 in the lower left corner is a basic condition, the photographing equipment is the basic system, and the photographing setting is auto. In the basic system, for example, the lens is a standard lens.

  AC2 is a case where the photographing equipment is the basic system and the photographing setting is changed by one. For example, this is a case where exposure correction is set as a shooting setting. AC3 is a case where the photographing equipment is a basic system and two photographing settings are changed. For example, when aperture priority is set in addition to exposure correction.

  AC4 is a case where the standard lens of the photographing equipment is replaced with a new lens a (less than 50,000 yen). Shooting settings remain auto. AC5 is a case where the photographic equipment is changed from a standard lens to a new lens b (50 to 100,000 yen). Shooting settings remain auto.

  In the following, an actual example of the advice screen shown in the above concept and an advice display device for displaying it will be specifically described. Here, the advice is changed in various ways to step up the photographer, but it goes without saying that either or both logics can be used when changing according to the shooting situation or when changing according to the photographer's experience. Yes.

<First Embodiment>
The first embodiment is an example in which an advice display device is realized by a single camera. FIG. 2 is a block diagram of the camera 1 on which the advice display device of the first embodiment is mounted. The camera 1 is an interchangeable lens type camera, and includes a camera body (also referred to as a camera body) 10 and a lens 300 connected to the camera body 10. A flash 310 can be additionally connected to the camera body 10.

  The camera body 10 includes a control unit 20, a storage unit 30, an imaging unit 40, an image processing unit 42, an operation unit 44, a touch panel 46, a clock 48, a position detection unit 50, a microphone 52, a display unit 54, and the like.

  The control unit 20 is a control unit that comprehensively controls the entire camera 1. The control unit 20 includes a CPU and a control program, and executes each control process by software processing by the CPU that has read the control program.

  The storage unit 30 stores the image data 30a, the burden degree table 30b, and other data in a nonvolatile manner. The storage unit 30 is, for example, a flash memory. The image data 30a is image data captured by the camera 1.

  The burden degree table 30b is a table in which the burden degree of the photographing equipment and the burden degree of the photographing setting are respectively described. The degree of burden of photographing equipment indicates the kind of photographing equipment that can be attached to the camera body 10 and the purchase burden cost. The degree of burden of shooting settings indicates the type of shooting settings prepared in the camera body 10 and the time and effort of the settings. Details will be described with reference to FIGS.

  The imaging unit 40 includes an imaging element (not shown) and an imaging circuit, photoelectrically converts the subject image formed by the lens 300, and outputs it as image data. The image processing unit 42 performs various processes such as an interpolation process, a γ process, a white balance process, and a compression process on the image data. The compressed image data is stored in the storage unit 30 as image data 30a.

  The operation unit 44 accepts a photographer's input operation using buttons and dials provided on the camera body 10 and notifies the control unit 20 of the input operation. When information of a photographer to be used at present is input from the operation unit 44, the photographer information is notified to the control unit 20. This is because there is a possibility that the camera 1 is used by a plurality of people, and the content of advice needs to be different for each photographer.

The touch panel 46 is provided integrally with the display unit 54, accepts a photographer's input operation on the screen, and notifies the control unit 20. The operation unit 44 and the touch panel 46 give an instruction for shooting setting from the photographer.

  The clock 48 is for recording the display of the current time, the shooting date and time, etc., and the shooting date and time is recorded as part of the tag data in the image data 30a. The position detection unit 50 specifies the shooting position by GPS and notifies the control unit 20 of the shooting position. The shooting position is recorded as part of the tag data in the image data 30a.

  The microphone 52 is for voice recording, and the recorded voice is recorded in the storage unit 30 along with the image data 30a when recording a moving image. The microphone 52 also records audio for shooting environment determination, which will be described later, to assist in subject determination.

  The display unit 54 is an image display unit configured by an LCD or the like. At the time of shooting, a live view is displayed on the display unit 54, and at the time of reproduction, an image based on the image data 30a is displayed. At the time of shooting, an advice screen is displayed on the display unit 54 based on the instruction.

  The control unit 20 includes a shooting control unit 100, a recording control unit 102, a shooting environment determination unit 110, an advice content determination unit 120, and a display control unit 122 as processing functions of the CPU described above. The imaging control unit 100 has an AE function and an AF function, and controls the lens 300, the imaging unit 40, the image processing unit 42, and the like during imaging. In addition, the shooting control unit 100 controls the lens 300, the imaging unit 40, the image processing unit 42, and the like according to shooting settings input from the operation unit 44 and the touch panel 46.

  The recording control unit 102 performs control to record the image data output from the image processing unit 42 in a predetermined area of the storage unit 30. The shooting environment determination unit 110 includes a device determination unit 112, a shooting setting determination unit 114, and a subject determination unit 116, and determines the current shooting environment.

  The equipment determination unit 112 determines the imaging equipment connected to the camera 1, for example, the type of the lens 300, the type of the flash 310, and the like based on a signal notified from each imaging equipment to the camera body 10. The equipment determination unit 112 determines the type of the connected photographing equipment based on the code indicating the type notified from the lens 300 or the flash 310 connected to the camera body 10. Note that a device such as a tripod for which no signal is notified to the camera body 10 is connected on a predetermined screen by a photographer, and the device determination unit 112 registers input information.

  Then, the equipment determination unit 112 records information about the photographer and the imaging equipment in the storage unit 30. In the storage unit 30, the photographic equipment information used corresponding to the photographer input from the operation unit 44 described above is sequentially stored. This is to change the handling of photographic equipment used in the past in order to display the photographic equipment unused for the current photographer as advice content described later.

  The shooting setting determination unit 114 determines the contents of shooting settings input from the operation unit 44 and the touch panel 46. The shooting setting determination unit 114 records the photographer and shooting settings in the storage unit 30. The storage unit 30 sequentially stores shooting setting information used corresponding to the photographer. Note that the shooting setting information includes the shooting equipment information at that time. This is for changing the handling of the experienced shooting setting in order to display the inexperienced shooting setting as the advice content in the same manner as the above-described shooting equipment. Of course, it is possible to apply not only the display order but also the advice priority such as size and timing.

  The subject determination unit 116 determines the type of subject and the shooting scene based on the image data. The subject determination unit 116 includes a face detection unit and determines the presence or absence of a person in the image. Further, the subject determination unit 116 determines, for example, a sports day or the sea if there is a voice or wave sound of a child recorded by the microphone 52. The subject determination unit 116 may use the shooting date and time as a determination material when determining the shooting scene as a night view.

  Based on each determination of the shooting environment determination unit 110, the advice content determination unit 120 selects a recommended shooting device and shooting setting from the shooting device and shooting settings of the burden degree table 30b, and recommends the recommended contents (hereinafter, advice). Content or content).

  Specifically, the advice content determination unit 120 is based on the current shooting environment determined by the shooting environment determination unit 110, based on the load degree table 30b, in the order of less burden based on the current shooting equipment and shooting settings. Determine one or more recommended photographic equipment and settings.

  The advice content determination unit 120 reads out the used equipment and the experienced shooting settings by the current photographer from the storage unit 30 when determining the photographing equipment and the shooting settings, For experienced shooting settings, reduce the burden. Note that the degree of burden may be reduced only for imaging equipment and shooting settings that have been used more than once.

  Further, the advice content determination unit 120 may exclude the combination of actually performed shooting equipment and shooting settings from the advice content. This is because there is little meaning to give advice about the combination of actual shooting equipment and shooting settings. Conversely, the advice content determination unit 120 may be set in advance so as not to reduce the burden of used equipment and experienced shooting settings, or to exclude combinations thereof.

  Further, the advice content determination unit 120 generates an expected sample image when the determined shooting equipment and shooting settings are applied to the current shot image. For example, when the recommended photographing equipment (advice content) is a lens having a different angle of view, the advice content determination unit 120 generates an image in which a range of a different angle of view is superimposed on the current photographed image as a sample image. .

  The advice content determination unit 120 generates an advice image using the generated sample image as advice content. The advice content determination unit is also abbreviated as an advice determination unit. The display control unit 122 performs control so that the generated advice image is displayed on the display unit 54 as an advice screen.

  FIG. 3 is a diagram illustrating an example of a shooting scene. This is a scene where a photographer photographs a still life (vase) placed on a desk as a subject in a room. FIG. 4A is a live view displayed on the display unit 54. On the upper right of the live view screen, a “contrivance” button for instructing the advice content screen display is displayed.

  FIG. 4B is an advice screen in which the “contrivance” button is pressed and advice content is displayed. The content SC1 is the current basic form, live view. This corresponds to AC1 in FIG.

  The content SC3 is a sample image by the macro lens a determined as the photographing equipment. This is an image obtained by superimposing a shooting range P on a live view when close-up shooting is performed with the macro lens a. This corresponds to AC4 in FIG. The advice content determination unit 120 determines that the subject is an indoor still-life shooting, and recommends the macro lens a as a low-priced device among shooting devices suitable for close-up shooting.

  The content SC2 is a sample image in which exposure correction is set as a shooting setting. This corresponds to AC2 in FIG. Based on each determination of the shooting environment determination unit 110, the advice content determination unit 120 determines exposure correction as a recommended shooting setting from the shooting setting in the burden degree table 30b. The advice content determination unit 120 determines that exposure correction is simple and useful as a shooting setting in indoor still life shooting. The content SC2 is an image in which the gain of the live view is lowered so that exposure correction is performed by −1 stage.

  FIG. 4C is a screen showing a state where the content SC3 is touched and selected on the screen of FIG. 4B. FIG. 4D is a screen on which the detailed advice content that is the detailed content of the selected content SC3 is displayed. When one advice content is selected on the advice screen, details of the advice content are displayed. An advice screen showing specific shooting advice, lens information, how to obtain the lens, and the like is displayed. Detailed content data of the advice content is stored in the storage unit 30.

  FIG. 5 is a flowchart for explaining a procedure of advice screen display processing in the first embodiment. The control unit 20 determines whether the shooting mode is set (step S10). If the control unit 20 determines that the shooting mode is not set (No in step S10), the control unit 20 executes a reproduction process (step S12). Description of the reproduction process is omitted.

  When the control unit 20 determines that the shooting mode is set (step S10 Yes), it starts imaging / sound collection (step S14). The control unit 20 displays the live view on the display unit 54 (step S16).

  The equipment determination unit 112 determines the photographing equipment currently mounted on the camera body 10 and its type (step S18). The subject determination unit 116 determines the shooting situation (step S20). The subject determination unit 116 determines the shooting situation from information such as the shooting date and time, the shooting location, and the sound in order to be used for specifying the subject.

  The subject determination unit 116 determines the type of the subject currently being captured from the determination result of the shooting situation and the live view image (step S22). Examples of the types of subjects include “indoor still life”, “flower / plant”, “person”, “landscape / nature”, “sports”, and the like.

  The control unit 20 determines the photographer (step S24). The equipment determination unit 112 reads out information on the used photography equipment by the current photographer from the information stored in the storage unit 30 (step S26). The shooting setting determination unit 114 reads out the shooting setting information experienced by the current photographer from the information stored in the storage unit 30 (step S28). Here, the experienced shooting setting information includes information on the corresponding shooting equipment.

  The shooting setting determination unit 114 determines whether or not there has been a control switching by operation (step S30). It is determined whether or not the shooting setting is changed by the photographer using the operation unit 44 or the touch panel 46 as described above. If the shooting setting determination unit 114 determines that there is no control switching by operation (No in step S30), the process proceeds to step S34.

  If the shooting setting determination unit 114 determines that there has been a control switch due to an operation (Yes in step S30), the shooting setting determination unit 114 determines the specific content of the shooting setting (step S32). Specific contents of the shooting setting are “exposure correction”, “aperture priority”, “SS (shutter speed) priority”, “MF (manual focus)”, and the like.

  The control unit 20 determines whether an instruction screen display instruction has been issued by the photographer (step S34). The advice screen display instruction is, for example, a touch operation on the “ingenuity” button shown in FIG. 4A described above.

  If the control unit 20 determines that no advice screen display instruction is issued from the photographer (No in step S34), the process proceeds to step S38. When the control unit 20 determines that an advice screen display instruction has been issued from the photographer (step S34 Yes), the control unit 20 performs an advice screen display process (step S36).

  FIG. 6 is a subroutine for explaining the procedure for displaying the advice screen. The advice content determination unit 120 reads the burden degree table 30b from the storage unit 30 (step S50). The advice content determination unit 120 determines the recommended photographic equipment by reducing the degree of the photographic equipment used by the current photographer from the photographic equipment table of the burden degree table 30b (step S52). The burden is lowered because the photographer is likely to own the used photographic equipment.

  FIG. 7 is an example of a burden degree table for photographing equipment. The photographic equipment burden degree table describes the price, the equipment burden degree calculated from the price, and the subject suitable for the photographic equipment for each of the photographic equipment. The equipment burden is an integer value of the unit price of 10,000 yen. The camera body b is a high-priced body on which an image sensor having a higher pixel than that of the current camera body 10 is mounted. It should be noted that the used photographic equipment may be uniformly set with the degree of equipment burden = 0 regardless of the purchase price, and since the cost burden is eliminated, the use of the equipment may be taken as the burden of shooting settings. When the degree of equipment burden is 0, it is excluded from the advice content.

  The advice content determination unit 120 is a table of photographic equipment as shown in FIG. 7, and selects from the photographic equipment suitable for the current subject, based on the equipment of the current camera 1, in ascending order of burden. Determine the recommended shooting equipment. For example, if the current camera 1 has only a standard lens and the subject is determined to be an indoor still life, the advice content determination unit 120 recommends the recommended camera in the order of the macro lens a, the ring flash, and the macro lens b. To decide. If the macro lens b corresponds to a used photographic equipment, it will be easy for the user and the burden level will be reduced (for example, 1). Degrees are excluded as 0.

  For example, when a ring flash is attached to the current camera 1, the advice content determination unit 120 determines recommended photographing equipment in the order of the macro lens a, the macro lens b, and the camera body.

  Next, the advice content determination unit 120 determines the recommended shooting setting by reducing the burden level of the shooting settings that have been experienced by the current photographer, from the shooting degree load level table of the load level table 30b (step S1). S54). The reason for lowering the burden is to display advice content that has never been experienced.

  FIG. 8 shows an example of a shooting setting burden degree table. The shooting setting burden degree table is a table showing setting burden degrees and suitable subjects in various shooting settings.

  The setting burden degree is an integer indicating the degree of burden on the operation, and the numerical value becomes larger as the burden is increased. For example, since the exposure correction only sets correction values such as +1 and −1, the operation is not time-consuming and the setting burden is 1.

  For aperture priority and SS (shutter speed) priority, an appropriate aperture value and shutter speed must be input, and it takes a little time and effort, so the setting burden is set to 2. Furthermore, since MF (manual focus) has to operate the lens while watching the live view, the operation is laborious, so the setting burden is set to 3. Note that the experienced shooting setting is excluded when the burden level is reduced to 0 when the experience level is lowered.

  Also, the various shooting settings have suitability according to the subject as with the shooting equipment. For example, exposure correction is recommended for subjects such as “indoor still life”, “flower / plant”, “person”, “landscape / nature”. Special image processing is processing for processing an image into a monochrome image, an illustration-like image, a watercolor-like image, or the like. Special image processing is recommended for subjects such as “flowers / plants”, “persons”, and “landscapes / nature”.

  Then, the advice content determination unit 120 uses the shooting setting burden degree table shown in FIG. 8 in the order of least burdening, based on the shooting settings of the current camera 1, from the shooting settings suitable for the current subject. To determine some recommended shooting settings.

  The advice content determination unit 120 creates an advice image based on the determined shooting equipment and shooting settings (step S56). The advice content determination unit 120 may exclude only content that matches the combination of the experienced shooting setting and the used shooting device from the determined shooting device and shooting setting.

  The display control unit 122 displays an advice screen based on the advice image on the display unit 54 (step S58). The advice screen shown in FIG. 4B is displayed.

  The advice content determination unit 120 determines whether any advice content has been selected on the advice screen (step S60). If the advice content determination unit 120 determines that no advice content has been selected (step S60 No), the advice content determination unit 120 proceeds to step S64.

  When the advice content determination unit 120 determines that the advice content has been selected (step S60 Yes), it creates a detailed screen of the selected advice content, and the display control unit 122 displays it on the display unit 54 (step S62). A detail screen as described in FIG. 4D is displayed.

  The control unit 20 determines whether an instruction to delete the advice screen has been issued (step S64). The erase instruction is, for example, a touch operation instruction to an erase button (not shown) on the advice screen. Alternatively, the deletion instruction may be that the display time of the advice screen has passed a certain time.

  If the control unit 20 determines that the advice screen is not deleted (No in step S64), the process proceeds to step S32 in FIG. If the control unit 20 determines that an instruction to delete the advice screen has been issued (step S64 Yes), the control unit 20 deletes the advice screen of FIG. 4B or 4D (step S66), and proceeds to step S32 of FIG.

  Returning to FIG. The control unit 20 determines whether a shooting operation has been performed by pressing the release button of the operation unit 44 (step S38). If the control unit 20 determines that the photographing operation is not performed (No in step S38), the control unit 20 returns to step S10. When the control unit 20 determines that a shooting operation has been performed (Yes in step S38), the control unit 20 executes shooting (step S40).

  The control unit 20 determines whether or not the photographing mode end operation has been performed by operating the mode switching button of the operation unit 44 (step S42). When determining that the photographing mode end operation has been performed (Yes in step S42), the control unit 20 switches to the reproduction mode and performs a reproduction process (step S12).

  If the control unit 20 determines that the photographing mode end operation has not been performed (No in step S42), the control unit 20 determines whether the power-off operation has been performed (step S44). When determining that the power-off operation has not been performed (No at Step S44), the control unit 20 returns to Step S10. When determining that the power-off operation has been performed (Yes in step S44), the control unit 20 performs a power-off process. The camera control process ends.

  FIG. 9 shows advice contents based on the tables shown in FIGS. 7 and 8 arranged in two-dimensional coordinates as shown in FIG. 1 when the subject is an indoor still life. The vertical axis is the equipment burden, and the horizontal axis is the set burden. However, in FIG. 9, for the sake of explanation, each piece of advice content is expressed not by a sample image but by contents, and the upper part shows the photographing equipment and the lower part shows the type of photographing setting.

  D1 is a frame indicating a range displayed as an advice screen when a combination of a standard lens and auto is used as a reference. The contents AC11, AC12, and AC13 of D1 correspond to the contents SC1, SC2, and SC3 shown as sample images in FIG. 4B.

  When the current camera 1 is changed, the range displayed on the advice screen is moved accordingly. For example, when the camera 1 is changed from “combination of standard lens and auto” to “combination of macro lens a and exposure correction”, D2 is based on “combination of macro lens a and exposure correction”. The advice screen shown in the range is created. In the advice screen of D2, the content AC14 is the reference.

  As described above, according to the first embodiment, the recommended photographing equipment and photographing settings are provided as advice information for photographing a good work (photograph) as information in a combined form, not a single photographer. Can be used as more easily accessible information. This is because, in order to take a good picture, it is necessary to select both appropriate photography equipment according to the subject and to use photography technology.

  Furthermore, in the first embodiment, the photographing equipment is displayed in the order of low price, and the photographing settings are displayed in the order in which the operation is not troublesome, that is, the order in which the burden degree is low. Can be executed from various shooting settings, making it easier to approach.

  In the first embodiment, since the recommended photographing equipment and photographing settings are displayed as advice information in the form of a sample image that will be obtained, the photographing equipment is photographed as compared to simply displaying the photographing equipment by name. This is useful when selecting equipment and shooting settings.

  Further, since used photography equipment and experienced photography settings are stored and the burden is set low, it is possible to display more practical advice content tailored to the photographer. In addition, since the combination of the currently used photographic equipment and shooting settings is not displayed as advice content, it is possible to prevent unnecessary advice from being displayed.

Second Embodiment
The second embodiment is an example in which an image stored in an external server is used as advice content. Here, the external server is an image management server managed by a photo posting circle or the like. In the first embodiment described above, the recommended shooting equipment and shooting settings are displayed in the form of a sample image converted from the current live view. In the second embodiment, an advice screen is displayed in which an image actually taken with recommended shooting equipment and shooting settings is used as advice content.

  FIG. 10 is a diagram illustrating a configuration of the camera 1 and a server 500 connected to the camera 1 via the network 600. In the camera 1 of the second embodiment, the configuration of the camera body 10a is partially different. The same parts as those of the camera body 10 of the first embodiment are denoted by the same reference numerals, and different parts of the camera body 10a will be mainly described.

  The camera body 10 a includes a communication unit 60 that communicates with the server 500 via the network 600. As will be described later, since the advice content is determined by the server 500, the advice content determination unit 120 is unnecessary from the control unit 20a of the camera body 10a. Similarly, the burden degree table 30b is not required from the storage unit 30.

  In addition, the display control unit 122 creates an advice screen based on the advice content transmitted from the server 500 and displays the advice screen on the display unit 54.

  As described above, the server 500 is a server operated by a photo posting circle, an SNS (Social Networking Site), and the like, and accumulates and manages images provided or applied by members. The server 500 includes a communication unit 502, an advice content determination unit 504, a content image storage unit 506, and a burden degree table 508. The communication unit 502 communicates image data and other information with the camera 1 which is a terminal connected via the network 600.

  The advice content determination unit 504 determines advice content from the image data stored in the content image storage unit 506, and outputs image data corresponding to the determined advice content to the communication unit 502. The content image storage unit 506 accumulates, as a content image for advice content, image data that is permitted to be distributed in advance as advice content by the photographer.

  The burden degree table 508 is the same table as the burden degree table 30b, and describes the degree of burden of the photographing equipment and the degree of burden of the shooting setting. Based on the shooting environment (subject type, shooting equipment, shooting settings) transmitted from the camera 1, the advice content determination unit 504 receives advice content with less burden from the content image storage unit 506 using the load degree table 508. decide.

  FIG. 11A is a live view screen of the second embodiment displayed on the display unit 54. The subject to be photographed is an indoor still life. In the upper right corner of the live view screen, a “contrivance button” for displaying the advice screen is displayed. FIG. 11B is an example in which the advice screen is displayed on the display unit 54 by touching the contrivance button in FIG. 11A. An advice screen based on the advice content transmitted from the server 500 is displayed.

  In FIG. 11B, the content SC10 at the lower left is a reduced image of the live view of FIG. 11A. Content SC11, content SC12, and content SC13 are content images transmitted from server 500. The subject of the content image is an indoor still life.

  The content SC11 on the right side of the content SC10 is, for example, an image shot with the same shooting equipment as the current camera 1 with the shooting setting set to exposure correction. The content SC12 above the content SC10 is, for example, an image in which the macro lens a is used as the lens 300 and the shooting setting is automatically set. The content SC13 on the upper right side of the content SC10 is, for example, an image obtained by using the macro lens a as the lens 300 and shooting settings with exposure correction.

  FIG. 12 is a flowchart for describing processing for displaying an advice screen according to the second embodiment. The advice screen display processing in the second embodiment includes processing that is common to the advice screen display processing in the first embodiment described in FIG. Processing common to the first embodiment will be briefly described.

  Steps S100 to S120 in FIG. 12 have the same contents as steps S10 to S32 in FIG. When an advice screen display instruction is given on the screen as shown in FIG. 11A (step S122), the advice screen is displayed (step S124).

  FIG. 13 is a sequence diagram for explaining processing performed between the camera 1 and the server 500 regarding the advice screen display. The processing by the camera 1 is shown in the left column, and the processing by the server 500 is shown in the right column.

  The control unit 20a performs shooting environment determination (step S160). The control unit 20a determines the above-described equipment determination (step S106), photographing state determination (step S108), subject determination (step S110), photographer determination (step S112), used photographing equipment determination (step S114), and experienced. The shooting environment is determined based on the shooting setting determination (step S116) and the shooting setting determination (step S120).

  The control unit 20a transmits the determination data regarding the determined imaging environment to the server 500 through the communication unit 60 (step S162). The shooting environment determination data includes data on subject type, shooting equipment, and shooting settings. The shooting environment determination data includes used shooting equipment information and experienced shooting setting information by the current photographer described in the first embodiment.

  The server 500 receives the shooting environment determination data from the camera 1 through the communication unit 502 (step S164). The advice content determination unit 504 reads the burden degree table 508 (step S166). The burden degree table 508 is the same as that shown in FIGS.

  The advice content determination unit 504 selects a content image corresponding to the camera 1 from the content image storage unit 506 based on the shooting environment determination data (step S168).

  FIG. 14 is a diagram illustrating types of tag information attached to content images. Each content image is accompanied by data of “title / theme (corresponding to subject type), shooting location, shooting date / time, shooting equipment, shooting setting, photographer” as tag information.

  Furthermore, information related to the “acquisition difficulty” is also recorded in the tag information of each content image. The acquisition difficulty level is a value indicating that the subject itself or the shooting location is a special case. The acquisition difficulty indicates that the higher the value, the more difficult the subject is when the subject is a special object or a living thing or the shooting location is limited to overseas. The same applies when the shooting time is limited to a short period. The reason why the acquisition difficulty level is set is to prevent an image that is special and uncommon, such as a subject, from being easily selected as advice content, because the burden of shooting equipment and shooting settings is low. .

  When the server 500 registers an image in the content image storage unit 506, the acquisition difficulty level may be determined from the content of the tag information, or the posting member may acquire the image in advance in the image. May be numbered. An example of the advice screen including the difficulty level of acquisition will be described with reference to FIG.

  FIG. 15 is a table showing an example of each content image stored in the content image storage unit 506. No (1, 2,...) In the left column is the number of each content image. The contents based on the tag information as described in FIG. 13 are described for each content image. For example, the content image of No. 50 is “Shooting title: Indoor still life”, “Shooting place: Tokyo Hachioji”, “Shooting date and time: 12:00 on June 20, 2014”, “Shooting equipment: Camera a, Macro lens a” "," Shooting setting: exposure correction "," photographer: mm ", and" (acquisition) difficulty level: 1 ".

  Here, if the subject type of the shooting environment determination data transmitted from the camera 1 is an indoor still life, the advice content determination unit 504 first searches the content image storage unit 506 for No50, 51,.・ Select a content image such as

  Next, based on the burden degree table 508, the advice content determination unit 504 has previously described content images whose burden degree is one rank higher than the current photographing equipment and photographing settings of the camera 1 as described above. A content image (No. 50, 51...) Having the same subject type is selected. As in the first embodiment, the advice content determination unit 504 may reduce the burden level of the burden level table 508 for used shooting equipment and experienced shooting settings by the current photographer.

  Note that the advice content determination unit 504 may refer to the acquisition difficulty level and may not select a content image with a high difficulty level. Conversely, the advice content determination unit 504 may ignore the acquisition difficulty level in selecting a content image in step S168.

  If the current photographing equipment of the camera 1 is a standard lens and the current photographing setting is auto, the content image No. 51 corresponds to one rank higher in the photographing setting. Similarly, the content image of No. 53 corresponds to one rank higher than the shooting equipment, and the content image of No. 50 corresponds to higher rank by the shooting equipment and shooting setting. Note that the advice content determination unit 504 may uniformly exclude content that matches the combination of the experienced shooting setting and the used shooting device from the determined shooting device and shooting setting. This is because there is little meaning to give advice about the combination of actual shooting equipment and shooting settings.

  The advice content determination unit 504 reads the selected content image from the content image storage unit 506 (step S170). The server 500 transmits the selected content image to the camera 1 through the communication unit 502 (step S172).

  The camera 1 receives the transmitted content image through the communication unit 60 (step S174). The display control unit 122 creates an advice screen (step S176). The advice screen as described with reference to FIG. 11B is created. The content image of No. 51 corresponds to the content SC11, the content image of No. 53 corresponds to the content SC12, and the content image of No. 50 corresponds to the content SC13.

  The display control unit 122 displays the advice screen on the display unit 54 (step S178). Then, the process proceeds to step S126 in FIG.

  Returning to FIG. The control unit 20a determines whether or not a shooting operation has been performed (step S126). If it is determined that a shooting operation has not been performed (No in step S126), the control unit 20a returns to step S100. When determining that the photographing operation has been performed (Yes in step S126), the control unit 20a performs photographing (step S128).

  Here, the recording control unit 102 appends each tag information described with reference to FIG. 13 to the captured image and records the tag information in the storage unit 30 as image data 30a. Each tag information is information determined in steps S106 to S116 and step S120. This is because the captured image captured by the camera 1 is registered as a content image in the content image storage unit 506 of the server 500.

  Returning to step S100, when the control unit 20a determines that the shooting mode is not set (step S100: No), it starts the reproduction process (step S140). The control unit 20a displays a file list such as an index image in response to an instruction from the photographer (step S142). The control unit 20a determines whether a file is selected in the file list (step S144). If the control unit 20a determines that no file is selected in the file list (No in step S144), the process proceeds to step S152.

  When the control unit 20a determines that the file is selected in the file list (step S144 Yes), the control unit 20a reproduces the selected image (step S146). Furthermore, the control unit 20a determines whether an instruction to transmit the selected image as a content image has been given (step S148).

  The photographer can register his / her photographed image in the server 500 as a content image for the advice screen. If the control unit 20a determines that there is no instruction to transmit as a content image (No in step S148), the control unit 20a proceeds to step S152.

  When the control unit 20a determines that an instruction to transmit the selected image as a content image has been given (Yes in step S148), the control unit 20a transmits the selected image to the server 500 (step S150). The server 500 stores and registers the received image in the content image storage unit 506 as a content image.

  The control unit 20a determines whether an operation for ending reproduction has been performed (step S152). If the control unit 20a determines that the operation to end the reproduction has not been performed (No in step S152), the control unit 20a returns to step S140. When determining that the reproduction end operation has been performed (Yes in step S152), the control unit 20a returns to step S100.

  In addition, since step S130 and step S132 are the same as the process of step S42 and step S44, description is abbreviate | omitted.

  A configuration example other than FIG. 10 in the second embodiment will be briefly described. FIG. 16 is a diagram showing another system to which a mobile terminal is added. The mobile terminal is, for example, a smartphone. The camera 1 is connected to the portable terminal 610a by wire or wireless. The mobile terminal 610a is connected to the network 600 such as the Internet via the base station 620, and the server 500 is connected to the network 600.

  Thereby, the camera 1 is connected with the server 500 via the portable terminal 610a. An image taken by the camera 1 can be registered as a content image in the content image storage unit 506 of the server 500 via the portable terminal 610a. In addition, the content image selected by the server 500 according to the shooting environment of the camera 1 can be displayed by the camera 1 via another portable terminal 610 a connected to the network 600.

  In addition, the photographed image can be registered as a content image in the content image storage unit 506 of the server 500 from the portable terminal 610b.

  According to the second embodiment as described above, it is possible to more accurately present an image obtained by shooting equipment and shooting settings that are one rank higher by displaying an actual shot image, although it is taken by another person. it can. This is because there is a limit to the expression by the sample image. Further, since used photography equipment and experienced photography settings are stored and the burden is set low, it is possible to display more practical advice content tailored to the photographer. In addition, since the combination of the currently used photographic equipment and shooting settings is not displayed as advice content, it is possible to prevent unnecessary advice from being displayed.

<Other display forms such as advice screens>
FIG. 17 is an example of a subject type selection screen. So far, it has been described that the subject type is determined by the subject determination unit 116, but subject determination is not limited to this. For example, as shown in FIG. 18, a subject type input screen may be prepared in advance in the camera 1, and the subject type may be input on the screen prepared by the photographer.

In the advice screen shown in FIG. 19A, it is assumed that the content SC20 indicated by a thick frame in the display range R is selected by touch. FIG. 19B shows a changed advice screen. The display range R is changed so that the advice screen is switched and the content SC20 is arranged at the lower left corner of the screen.

  FIG. 20 is a screen in which a slider for moving the display position is added to the advice screen of FIG. The lever Lx is a lever that changes the display range in the direction of the X axis (setting burden). The lever Ly is a lever that changes the display range in the direction of the Y-axis (equipment burden level). For example, by moving the lever Lx to the right, it is possible to display advice content with a higher setting burden. Also, by moving the lever Ly to the right, it is possible to display advice content with a higher degree of equipment burden.

  FIG. 21 is an advice screen to which an axis of acquisition chance degree is added. The parameters of the advice screen are not limited to the setting burden level (X axis) and the equipment burden level (Y axis), and other elements may be added. As shown in FIG. 21, an acquisition chance degree that is the reverse of the acquisition difficulty described in FIG. 15 may be added as the Z axis.

  For example, when the subject can be photographed for several days throughout the year, it is usually difficult to obtain, but when the current time is within the photographable period, the content should be prominently displayed on the advice screen. To present. That is, the content SC30 is an advice content with a high degree of acquisition chance only during this period. Conversely, the content SC30 is not displayed except during this period.

  In the above embodiment, the control unit 20 (20a) has been described as being realized by software processing by the CPU that has read the control program. However, part or all of the control unit 20 (20a) may be configured by hardware.
