  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block configuration diagram showing an outline of an electrical configuration of a digital camera 1 according to the present invention.

  The digital camera 1 has the best shot photographing function described above, compresses and expands an image picked up by the CCD 2 as an image pickup means, and has a predetermined format such as a unified standard DCF (Design rule for Camera File system). ) And JPEG (Joint Photographic Expert Group), and an image processing function for generating and reproducing an image file having a format matching the JPEG (Joint Photographic Expert Group), and an MPU 3 including a clock having a calendar function.

  An optical image of the subject is formed on the light receiving surface of the CCD 2 through the fixed lens 4, the focus lens 5, and the diaphragm 6. The focus lens 5 is held by a drive mechanism 7 composed of an AF motor or the like, and moves forward and backward on the optical axis when a drive signal output from the AF driver 8 is supplied to the drive mechanism 7 by a control signal from the MPU 3. Perform focusing operation. The diaphragm 6 is driven by a drive signal generated by the diaphragm drive unit 9 based on a control signal from the MPU 3 and adjusts the amount of light of the subject image incident on the CCD 2.

  Further, a TG (Timing Generator) 10 that generates a timing signal is connected to the MPU 3, and a V driver 11 (vertical driver) drives the CCD 2 based on the timing signal generated by the TG 10. An analog imaging signal corresponding to the luminance of the image is output and sent to the analog signal processing unit 12. The analog signal processing unit 12 includes a CDS (Correlated Double Sampling) that holds an imaging signal output from the CCD 2, and a gain adjustment amplifier (AGC) that is an analog amplifier that is supplied with the imaging signal from the CDS. And an A / D converter (AD) that converts the analog imaging signal amplified and adjusted by the gain adjustment amplifier into a digital signal, and the output signal of the CCD 2 is sampled in accordance with the black level as a digital signal. Sent to MPU3.

  The MPU 3 is connected with a power supply circuit 13, an operation key unit 14 including various switch groups, a TFT liquid crystal monitor 15, a strobe 16, a DRAM 17, an MROM 18, and a card drive 19. A card 20 is installed. The operation key unit 14 is a mode switching key for switching between a recording (REC) mode for shooting and a playback (PLAY) mode for displaying a recorded image, an up / down key used for various setting operations. It consists of a plurality of operation keys such as a composite key in which left and right direction keys and a decision key are integrated, and sends an operation signal to the MPU 3 according to the user's key operation.

  The DRAM 17 is a working memory, and a digital signal (imaging signal) sent from the CCD 2 to the MPU 3 is temporarily stored in the DRAM 17 and subjected to various image processing by the MPU 3 and finally compressed. The image data is recorded on the memory card 20. The image data recorded on the memory card 20 is read out to the MPU 3 as necessary, and is generated into a digital video signal or an analog video signal through processing such as expansion processing, addition of a luminance signal and a color signal, and then liquid crystal Displayed by the monitor 15. On the liquid crystal monitor 15, an image periodically picked up in the recording mode is thinned to a predetermined number of pixels and then displayed as a through image. Further, the TFT liquid crystal monitor 15 functions as a display unit of the present invention, and displays a sample image and a selection screen, which will be described later, as necessary.

  The MROM 18 is a photographing condition storage unit, correspondence information storage unit, and history information storage unit of the present invention, and is a rewritable nonvolatile memory such as an EEPROM or a flash memory. In the memory space of the MROM 18, as shown in FIG. 2, a program data area 18a in which various control programs necessary for control of each unit and data processing in the MPU 3 are stored, and an appropriate exposure value (EV) at the time of photographing. The program AE data constituting the program diagram showing the combination of the shutter speed, aperture value, and sensitivity for obtaining the image, various data areas 18b storing other data to be described later, and the scene data area 18c are secured. Yes.

  The scene data area 18c is used in the best shot mode, which is a lower mode of the recording (REC) mode, and in an operation state in which the best shot notification function is valid in the recording mode (hereinafter referred to as the best shot notification mode). The scene data 101 is composed of sample image data 102, shooting condition data 103, and explanatory text data 104. The sample image data 102 corresponds to each of a plurality of selectable shooting scenes prepared in advance and is sample image data displayed on the display screen of the TFT liquid crystal monitor 15 as necessary. The explanatory text data 104 is character string data of explanatory text indicating the contents of the plurality of shooting scenes displayed together with the sample image in the best shot mode.

  FIG. 3 shows the configuration of the shooting condition data 103. The shooting condition data 103 includes a scene name 103a which is a name of a plurality of shooting scenes and shooting of the digital camera 1 set in advance corresponding thereto. Data indicating conditions, that is, imaging parameters 103b indicating the contents of a plurality of control items that can be controlled in the digital camera 1 such as focus control, shutter speed, aperture, EV shift amount, sensitivity,...

  The various data area 18b stores the data constituting the scene search table T1 shown in FIG. 4 together with the program AE data described above, and the data constituting the scene learning table T2 shown in FIG. Is stored.

  The scene search table T1 (FIG. 4) is used in a shooting operation in the best shot notification mode to be described later, and includes a scene name 103a indicating a predetermined shooting scene and predetermined shooting parameter information 201 corresponding thereto. And an information table showing other information 202. The scene name 103 a is a part of what is included in the shooting condition data 103. The shooting parameter information 201 is data indicating setting contents of shooting parameters that are automatically set appropriately following the change of the subject in the digital camera 1 even if the user does not intend. In this example, the shooting parameter information 201 is AWB (auto white balance) and The setting content of AE (automatic exposure) is shown. It should be noted that “bright” and “dark” shown as AE setting contents in the figure more specifically indicate the brightness (EV of the subject corresponding to the combination of the shutter speed, aperture value, and sensitivity set by the AE control. Value). Other information 202 is sequentially acquired in the system information (in the figure, time, city name of the place of use, language used) stored in the digital camera 1 regardless of the operation mode, and in the shooting standby state. This is predetermined image information (color distribution in the figure) in the image data. In the present embodiment, the system information and the predetermined image information are the predetermined condition information in the present invention.

  The scene learning table T2 (FIG. 5) is history information of the present invention that is rewritten as needed when shooting in the best shot notification mode, which will be described later, and is one or a plurality of shootings set manually. It is table information which shows the priority of the some imaging | photography scene with respect to the setting content of a parameter. The priority depends on the number of selections when the setting contents of one or a plurality of shooting parameters are the same.

  The MPU 3 performs AE (automatic exposure) control, AF (autofocus) control, and AWB (auto white balance) control by operating based on the control program stored in the MROM 18. Further, in the above-described best shot mode, display control of a sample image or the like according to a user's operation and control regarding setting of shooting conditions corresponding to a sample image (shooting scene) selected by the user are performed. Furthermore, in the best shot notification mode, the detection means, search means, deletion means, acquisition means, second search means, setting means, designation control means, priority order setting means, display control means of the present invention are performed by performing the processing described later. , Function as setting control means.

  Next, the operation of the digital camera 1 having the above configuration will be described. 6 and 7 are flowcharts showing the procedure of the imaging process executed by the MPU 3 in the best shot notification mode.

  Upon shooting processing, the MPU 3 immediately starts displaying a through image on the TFT liquid crystal monitor 15 (step S1), and immediately checks whether the user has manually set shooting parameters. If there is no setting (NO in step S2), the MPU 3 continues. Proceed to step S18. Then, if the user presses the shutter key or there is no instruction to end shooting by the mode switching operation (NO in both steps S18 and S21), the process returns to step S2.

  On the other hand, if there is a manual setting of the shooting parameter while displaying the through image (YES in step S2), the setting parameter list 401 as shown in FIG. 8 stored in the DRAM 17 is updated (step S3). The setting parameter list 401 is list data indicating setting contents for a plurality of shooting parameters, focus, shutter speed, aperture, EV shift amount, sensitivity, white balance, etc. that can be manually set by the user. FIG. 8 shows an example in which the manually set shooting parameter is only focus and it is set to macro.

  Subsequently, the photographic scene corresponding to the photographic condition data 103 including one or a plurality of photographic parameter settings existing in the updated setting parameter list 401 is searched from the photographic scenes prepared in advance (step S4). If there is no corresponding shooting scene (“not applicable” in step S5), the process immediately proceeds to step S18 to check whether or not the shutter key has been pressed.

  If there is only one search result (“1” in step S5), it is further checked whether the automatic scene setting function is valid (step S6). The scene automatic setting function is a function that allows the user to set in advance whether or not to use the scene. If the function is valid (YES in step S6), the shooting conditions indicated in the shooting condition data 103 of the searched shooting scene are immediately set as shooting conditions at the time of shooting (step S7). As a result, shooting conditions suitable for a shooting scene similar to the shooting scene at that time are automatically set. Thereafter, the process proceeds to step S18 to confirm whether or not the shutter key is pressed.

  Further, when the determination result of the above-described step S5 is “plurality” and there are a plurality of the above-described search results, the search results (a plurality of shooting scenes) are obtained using the scene search table T1 (FIG. 4). Further narrowing down (step S8). In other words, other than manually set shooting parameters, the setting details of shooting parameters set by AE control, AWB control, etc., system information such as item data, and image information such as color distribution obtained from image data as a through image Narrow down the shooting scene. Even when narrowing down is successful at this stage (YES in step S9), it is confirmed whether or not the automatic scene setting function is valid, and if it is valid (YES in step S6), the searched shooting scene is searched. The shooting condition indicated in the shooting condition data 103 is immediately set as the shooting condition at the time of shooting (step S7).

  Further, when the scene search table T1 is used and the number of shooting scenes cannot be narrowed down to one and there are a plurality of shooting scenes (NO in Step S9), the scene learning table T2 ( The priority order is set using FIG. 5) (step S10). Thereafter, the sample image data of a plurality of narrowed shooting scenes are read out and displayed on the through image being displayed according to the set priority order to prompt the user to select one of the sample images (step S11). That is, a shooting scene having shooting conditions similar to the shooting conditions set or changed (hereinafter simply referred to as setting) manually or automatically is selected from shooting scenes prepared in advance for setting (selecting) shooting conditions. Display as a candidate.

  FIG. 9 shows an example of a display method of a plurality of sample images at that time. FIG. 5A selectively displays one sample image 502 on the through image 501. In this case, a selection button 503 such as “1: set”, “2: display next”, and “3: cancel” that can be selected by a predetermined key operation is displayed together with the sample image 502 to display the user. In accordance with a predetermined key operation (feed operation) in a state where “2: display next” is selected, the sample images 502 are sequentially switched and displayed according to the priority order, while “1: set” is selected. If a predetermined key operation (confirmation operation) is performed in this state, the sample image 102 displayed at that time is set as the sample image selected by the user. FIG. 5B shows a case where all the sample images 502 are collectively displayed on the through image 501 in the arrangement order according to the priority order. In this case, a cursor for selecting a sample image (selection frame or the like) is separately displayed and moved according to a predetermined key operation to allow the user to select an arbitrary sample image and perform a predetermined confirmation operation. Accordingly, any one of the sample images indicated by the cursor is set as the sample image selected by the user. A cancel button 504 is also displayed on the through image 501.

  Subsequently, when a plurality of sample images 502 are selectively or collectively displayed by the above-described method and the user gives an instruction to select one of the sample images 502 (setting or confirming operation) (step S12). YES), the shooting parameter 103b indicated by the shooting condition data 103 stored corresponding to the selected sample image is set as a shooting parameter to be used when shooting the recorded image (step S13). Further, the scene learning table T2 is updated (step S14). In other words, shooting parameters newly set by the user and selected shooting scenes are added, the number of times of selection of shooting scenes already stored in correspondence with the shooting parameters is updated, and the same required as a result. The priority order in the shooting scene corresponding to the shooting parameter is changed. Then, the sample image 102 being displayed is erased (step S15).

  Further, when the user performs a cancel operation in a state where a plurality of sample images 102 are selectively or collectively displayed by the method as described above (YES in step S16), the setting parameters stored at that time are stored. The stored contents of the list 401 (FIG. 8) are cleared (step S17), and the sample image 102 being displayed is deleted (step S15).

  Thereafter, the processes in steps S2 to S17 described above are repeated until the user presses the shutter key or there is an instruction to end shooting by the mode switching operation (both NO in steps S18 and S21). In other words, each time one of the shooting parameters is set (changed) by the user, the shooting scene at that time is simply determined based on the contents of the set one or more shooting parameters, and the determined shooting scene and The user is informed that a similar shooting scene is already prepared for setting the shooting conditions, and at the same time, if the user desires, the shooting conditions corresponding to the similar shooting scene are set.

  If the shutter key is pressed during that time (YES in step S18), recording for recording and recording processing of the captured subject image are executed (step S19). That is, if step S7 or step S13 has been executed immediately before, shooting is performed using shooting conditions prepared in correspondence with any of a plurality of shooting scenes prepared in advance, otherwise In this case, shooting is performed using the same shooting conditions as in the previous shooting, or shooting conditions in which a part of the shooting conditions in the previous shooting is changed by the user. Thereafter, the setting parameter list 401 is cleared (step S20), and one shooting process is terminated. If step S17 has been executed immediately before the shutter key is pressed, such processing is skipped. Thereafter, when there is an instruction to end shooting by the mode switching operation (YES in step S21), all the processes are ended.

  As described above, in the digital camera 1 according to the present embodiment, in the shooting standby state in the best shot notification mode, when any shooting parameter is manually set by the user, the shooting condition is set (selected) in advance. Of the prepared shooting scenes, a sample image 502 of a shooting scene having shooting conditions similar to the shooting conditions set manually or automatically is displayed as a selection candidate on a part of the through image 501. Therefore, the user can know when there is a shooting scene that matches or resembles the actual shooting scene while performing the work of determining the subject and the composition without selecting the shooting scene using the best shot function. it can. Therefore, it is possible to perform the setting operation of the shooting conditions suitable for the shooting scene more easily than in the past. This is particularly convenient when shooting continuously with different subjects and compositions. In addition, by selecting a sample image displayed on a part of the through image as a selection candidate, it is possible to immediately set a shooting condition suitable for a shooting scene that matches or resembles an actual shooting scene. This also makes it easier to set the shooting conditions suitable for the shooting scene than before.

  Further, in the present embodiment, the setting contents of all the shooting parameters set manually are stored in the setting parameter list 401, and the shooting conditions of the setting candidates are searched based on the setting contents of these shooting parameters. Therefore, every time the types of shooting parameters that are manually set increase, the accuracy of adaptation of the shooting scene that is a selection candidate for the actual shooting scene can be automatically increased. At the same time, the number of shooting scenes that are selection candidates can be reduced. In addition, since the user can delete the setting contents of the shooting parameters stored before that at an arbitrary time as needed, it is convenient.

  Further, when there are a plurality of search results of setting condition shooting conditions based on manually set shooting parameter settings, the above-described scene search table T1 is used to manually set the shooting parameters. Since the search is narrowed down based on the settings of the shooting parameters other than automatically set and other information 202, it is possible to increase the accuracy of matching the shooting scene that is a selection candidate for the actual shooting scene and to select the selection. It is possible to reduce the number of candidate shooting scenes.

  In addition, when there are a plurality of selection candidate shooting scenes, the above-described scene learning table T2 is used, that is, a shooting scene selected from the selection candidates in the past, and one or more when the selection scene is selected. Priorities are assigned based on the history information of the shooting parameter settings, and sample images of each shooting scene are displayed in accordance with the priority, so even if there are a large number of shooting scenes as selection candidates, actual shooting is performed. A shooting scene that matches or is similar to the scene can be easily selected. When there are multiple selection candidate shooting scenes, the shooting conditions of the shooting scene with the highest priority described above are automatically set as shooting conditions at the time of shooting, for example, on condition that the automatic scene setting function described above is effective. It may be set automatically.

  Further, in this embodiment, if the automatic scene setting function is enabled in advance, if there is only one candidate shooting scene, shooting conditions suitable for the shooting scene can be automatically set. Easy to use. In the present embodiment, when there is one selection candidate shooting scene, the sample image 502 indicating the shooting scene is not displayed, but it is displayed only for a certain period of time. May be.

  On the other hand, in the present embodiment, the automatically set shooting parameter setting information and other information 202 are used for a narrowing search after an initial search based on the manually set shooting parameter setting content. However, both or any one of them may be used together with the setting contents of the shooting parameters set manually in the initial search.

  Further, in the present embodiment, the search timing of the above-described setting candidate shooting conditions is set to the time when the shooting parameters are manually set by the user, but instead of or in parallel with this, the shooting parameters are set by automatic control. It can also be a point in time.

  Further, although the sample image 502 is displayed as a part of the through image 501 as the scene information of the present invention, the scene name 103a may be displayed instead of or together with the sample image 502.

  In the present embodiment, the present invention is applied to a digital camera. However, the present invention is not limited to this, and the present invention is applied to other camera devices such as a camera built in a portable information terminal such as a mobile phone. Can also be adopted.
