  This electronic still camera 1 has an operation mode (scene selection mode) that enables setting of photographing conditions by selecting a sample image described in the prior art, and includes a fixed lens 4 and a rear surface on the front side of the main body. On the side, a TFT liquid crystal monitor 15 is disposed, and an optical finder 51 and a strobe 16 are provided. Further, a power switch 52, a shutter key 53, a zoom operation switch 54, an operation mode switching switch 55 for switching between a recording mode (REC mode) and a playback mode (PLAY mode), a liquid crystal monitor, Various switches such as a switch 56, a flash key 57, a self-timer key 58, and a menu key 59 are provided.

  FIG. 2 is a block diagram showing an outline of the electrical configuration of the electronic still camera 1. The electronic still camera 1 compresses and expands an image picked up by the CCD 2 as an image pickup means, and a predetermined format, for example, a unified standard. The MPU 3 is mainly configured with an image processing function that generates and reproduces an image file in a format that conforms to DCF (Design Rule for Camera File system) and JPEG (Joint Photographic Expert Group). 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 made 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 light quantity 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 unit circuit 12. The unit circuit 12 includes a CDS that holds an imaging signal output from the CCD 2, a gain adjustment amplifier (AGC) that is an analog amplifier that is supplied with the imaging signal from the CDS, and an analog imaging that is amplified and adjusted by the gain adjustment amplifier. An A / D converter (AD) that converts the signal into a digital signal is used. The output signal of the CCD 2 is sampled with the black level matched and sent to the MPU 3 as a digital signal.

  The MPU 3 is connected to the power supply circuit 13 and the operation key unit 14 including the various switch groups shown in FIG. 1, the TFT liquid crystal monitor 15, the strobe 16, the DRAM 17, the MROM 18, the card drive 19, and the clock circuit 20. The card drive 19 is loaded with a CF (Compact Flash (registered trademark)) card 21. The clock circuit 20 has a calendar function, and functions as reference information acquisition means of the present invention in the present embodiment by outputting the current date data, day of the week data, and time data to the MPU 3. The DRAM 17 is a working memory, and the CF card 21 is a detachable recording medium for image recording. A digital signal (imaging signal) sent from the CCD 2 to the MPU 3 is temporarily stored in the DRAM 17 and various images are also stored by the MPU 3. After the processing, it is finally recorded on the CF card 21 as a compressed video signal. The recorded video signal is read out to the MPU 3 as necessary, and is generated into a digital video signal or an analog video signal through processes such as expansion processing, addition of a luminance signal and a color signal, and is displayed on the TFT liquid crystal monitor 15. The That is, on the TFT liquid crystal monitor 15, images sequentially captured are displayed as through images in the recording mode, and images based on the image data recorded on the CF card 21 are displayed in the reproduction mode.

  The MROM 18 is a recording medium of the present invention, and is a program ROM in which various operation programs necessary for control of each unit and data processing in the MPU 3 are recorded. The MROM 18 stores various data such as program AE data constituting a program diagram showing a combination of an aperture value (F) corresponding to an appropriate exposure value (EV) at the time of shooting and a shutter speed. Then, according to the program diagram, the MPU 3 performs AE control such as the charge accumulation time of the CCD 2, which is the shutter speed, the degree of opening of the diaphragm 6, and the gain setting of the gain adjustment amplifier (AGC) of the unit circuit 12. Then, AF (auto focus) control and AWB (auto white balance) control for driving the focus lens 5 are performed according to a predetermined program. Further, when the shutter key 53 is operated (during shooting), the flash auxiliary light emission by the strobe 16 and the light emission amount thereof are controlled as necessary, and functions as the control means of the present invention. Control related to setting of shooting conditions in select mode is performed.

  The MROM 18 includes data of a plurality of sample images constituting the shooting mode table 101 including scenes (sample images) having the contents shown in FIGS. 3 and 4 and shooting conditions, and shooting condition data corresponding to each sample image, and Data constituting the display control table 102 shown in FIG. 5 is stored.

  As shown in FIGS. 3 and 4, sample image data constituting the shooting mode table 101 is a type of subject (shooting scene) that is expected to have a high shooting frequency, such as various portraits, two persons, and the like. Image data such as two-shots, people and landscapes, mountains in the sunset, amusement parks, and night views of the city. Each sample image data is used for identification with other image data, and “1” to “29” indicating the basic display order when the sample image is displayed in the scene select mode. Consecutive scene numbers are assigned.

  The shooting condition data is a parameter indicating the setting contents of a plurality of control items (focus, shutter speed, aperture, EV shift amount, sensitivity,..., Flash) that can be controlled when shooting with the shutter key 53 pressed. . More specifically, numerical data and switch flag data, which are data for setting shooting conditions for obtaining the same shooting results as the corresponding sample images in the electronic still camera 1, that is, This is setting data for a specific shooting mode.

  As shown in FIG. 5, the display control table 102 includes predetermined use conditions (conditions 1 and 2) relating to a predetermined time in a sample image (scene numbers “14 to 19”) related to a night shooting scene. When displaying a plurality of sample images as described above in the scene select mode, which is composed of data indicating the control contents indicating the order relationship (“first”, “tail”) of the display order with respect to other sample images Used to control the display order. The use conditions are set between 7 am and 5 pm (condition 1) and between 7 pm and 4 am (condition 2).

  Next, in the electronic still camera 1 having the above configuration, an operation when the scene select mode is selected by a photographer by a predetermined key operation will be described with reference to the flowchart of FIG.

  When the scene select mode is selected, the electronic still camera 1 first detects the current time (step SA1), and whether or not the current time matches any of the conditions indicated in the display control table 102 described above. Is determined (step SA2). If the current time does not match any of the conditions, the process immediately proceeds to step SA4 (NO in step SA2). If any of the conditions matches (YES in step SA2), the display control table 102 is displayed. The display order of the sample images is changed in accordance with the contents of (Step SA3). That is, as shown in FIG. 7, the normal display order indicated by the scene number (a in FIG. 7) matches “Condition 1”, for example, when the current time is 10:00 am. In some cases, the order position of the sample images of scene numbers “14-19” is changed to the display order that moves to the tail (b in the figure), and the condition of “condition 2” is met as when the current time is 9 pm. If it has been done, the order position of the sample images of the scene numbers “14 to 19” is changed to the display order for moving to the top (FIG. 3C). In this case, data indicating the display order after the change is stored in the DRAM 17.

  Subsequently, in step SA4, as shown in FIG. 8, a selection screen 202 including a sample image 201 based on the data stored in the MROM 18 is displayed on the TFT liquid crystal monitor 15 (step SA4), and in this state, the user selects it. When [+] or [-] of the selection key (zoom button 54) is pressed (YES in step SA5), according to the operation, the sample image 201 to be displayed follows the reference display order (scene number order), or When the display order after change is stored in the DRAM 17, the other sample images 201 are switched sequentially (in ascending order when [+] and descending order when [−]) according to the changed display order (step SA 6). This is repeated until the shutter key 53 (decision key) is pressed (NO in step SA7).

  That is, when the user sequentially switches the sample images 201 by operating the selection key, the selection screen 202 shows that the selection time in the scene selection mode does not match any of the above-described conditions and the processing in step SA3 is not performed. As shown in FIG. 8, a plurality of sample images are displayed in the order of scene numbers. On the other hand, if the time is from 7:00 am to 5:00 pm (condition 1), a plurality of sample images (scene numbers “14 to 19”) relating to the night scene are displayed last, and from 7:00 pm If it is until 4 am (condition 2), the sample images are displayed first. Thereby, in the former case, a plurality of sample images (scene numbers “14 to 19”) that cannot be selected at that time are displayed later, and as a result, other sample images can be selected ( Alternatively, the number of operations for displaying a plurality of sample images is highly likely. In the former case, the number of operations for displaying these sample images is reduced by displaying sample images that can be selected (or highly likely) at that time from the beginning.

  Thereafter, if any of the sample images 201 is displayed and the shutter key 53 (decision key) is pressed (YES in step SA7), that is, if any of the sample images 201 is selected, the sample image being displayed is displayed. Based on the photographing condition data stored in the MROM 18 corresponding to 201, the photographing condition at the time of photographing with the electronic still camera 1 is set, and the photographing standby state is set (step SA8). Thereafter, when the shutter key 53 is pressed (YES in step SA9), the image data is captured, and the captured image data is recorded on the CF card 21 (step SA10). As a result, it is possible to perform shooting under shooting conditions (shooting mode) suitable for shooting a subject simply by selecting a sample image 201 similar to the subject to be shot.

  In the above operation, as described above, when the shooting mode is set in the scene selection mode, a plurality of sample images (scene numbers “14 to 19”) related to the night scene are set according to the time at the time of the operation. By moving the order position to the head or tail, a plurality of sample images that can be selected (or highly likely) at that time are displayed at an early stage. Therefore, even if there are a large number of sample images and photographing condition data stored in advance in the MROM 18, the photographer can immediately display a desired sample image and select it. Therefore, it is possible to diversify the sample images without reducing the workability when selecting the sample images.

  In this embodiment, the display order of the sample images is controlled based on two types of usage conditions. However, control is performed based on a single usage condition, or three or more types of usage conditions are used. Control may be performed based on this. The same applies to the control content corresponding to each use condition. For example, the control content when the same use condition is matched may be different for each of a plurality of sample images to be controlled in the display order. . According to the present embodiment, in the case of performing control based on a single use condition, the sequence position of the sample images with scene numbers “14 to 19” is moved to the top within a predetermined time. A more remarkable effect can be obtained by performing the control.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. This embodiment has the same configuration as that shown in FIG. 1, and in particular, the notation language (menu language) of the menu screen displayed on the TFT liquid crystal monitor 15 is in Japanese or English at the initial setting. The present invention relates to an electronic still camera having a function that can be selected and set from types.

  In the present embodiment, the MROM 18 performs the same shooting mode table as that shown in FIGS. 3 and 4, the data constituting the display control table 302 shown in FIG. 9, and the operation shown in FIG. An operation program for storing the program is stored. The shooting mode table is composed of data related to a plurality of sample images (not shown) whose contents are different from those shown in FIGS. 3 and 4 although not shown. On the other hand, the display control table 302 is a predetermined sample image using the setting contents of the menu language as a use condition, that is, a sample image of scene numbers “11 to 16” in a plurality of sample images up to scene numbers “1 to n”. The content of the display control, that is, the data indicating the control content to prohibit the display under a specific condition.

  Here, the scene numbers “11 to 16” in the present embodiment will be described. Sample images with scene numbers “11” and “12”, sample images with scene numbers “13” and “14”, and scene number “15”. And “16” sample images are combined images each of which is a scene of the same kind, for example, a portrait or a night scene. The former (with an odd scene number) Sample images such as portraits with Japanese as a model are prepared, and the latter (even scene numbers) have sample images taken in English-speaking countries and portraits as models of Westerners. It is prepared.

  Hereinafter, in the electronic still camera having such a configuration, an operation when the scene select mode is selected by a photographer by a predetermined key operation will be described with reference to the flowchart of FIG.

  That is, when the scene select mode is selected, the electronic still camera checks the type of menu language set in advance (step SB1), and then refers to the display control table 302 to display a sample image to be hidden. The sample image to be displayed is specified in the subsequent processing. That is, when the menu language at that time is Japanese (condition 1), other sample images other than the sample images with the scene numbers “12”, “14”, and “16” are set as sample images to be displayed. When the menu language is English (condition 2), sample images other than the sample images with scene numbers “11”, “13”, and “15” are set as sample images to be displayed. Further, data indicating it is stored in the DRAM 17 (step SB2).

  Then, the same operation as that of the first embodiment is performed, and a plurality of sample images specified in step SB2 are displayed on the selection screen 202 (see FIG. 8) displayed on the TFT liquid crystal monitor 15, and the sample is displayed to the user. The images are switched in order of the scene number, and a desired image is selected (steps SB3 to SB6). During this time, a plurality of sample images with scene numbers “1 to n” are displayed on the selection screen 202. When the menu language is Japanese (condition 1), as shown in FIG. Is displayed while skipping (jumping) sample images of “12”, “14”, and “16”, and the menu language is English (condition 2), as shown in FIG. Are displayed while skipping the sample images having the scene numbers “11”, “13”, and “15”. That is, by replacing the sample images in the sample images constituting each combined image in accordance with the menu language and displaying them, a sample image having no sense of incongruity according to the photographer and the shooting location is displayed.

  After any sample image 201 is selected by pressing the shutter key 53 (decision key) in a state where any sample image 201 is displayed (YES in step SB6), the first embodiment The same processing is performed (steps SB7 to S9). As a result, it is possible to perform shooting under shooting conditions (shooting mode) suitable for shooting a subject simply by selecting a sample image 201 similar to the subject to be shot.

  Here, in the above operation, when the shooting mode is set in the scene select mode as described above, the sample images in the sample images constituting each combined image are replaced and displayed according to the menu language at the time of the operation. By doing so, a sample image without a sense of incongruity according to the photographer and the shooting location is displayed. Therefore, compared with the case where all the combined images are displayed, the number of operations for displaying a sample image that can be selected (or highly likely) can be reduced. As a result, even if there are a large number of sample images and photographing condition data stored in advance in the MROM 18, the photographer can immediately display a desired sample image and select it. Therefore, it is possible to diversify the sample images without reducing the workability when selecting the sample images.

(Other embodiments)
In the first embodiment described above, based on the display control table 102 (FIG. 5), the order position of the display order in the specific sample image with respect to the other sample images is controlled under the use conditions regarding the time. In the second embodiment, based on the display control table 302 (FIG. 5), the presence / absence of display of a specific sample image is controlled under the use conditions regarding the type of menu language. You may make it control the order position of the display order with respect to the other sample image in a specific sample image, or the presence or absence of the display of a specific sample image under a several use condition.

  The usage conditions in this case include various reference information that can be acquired according to the configuration of the electronic still camera, such as the time information and calendar information described above, GPS information (latitude / longitude / altitude), AE control, AF control, This is a use condition that can be determined based on subject information that changes for each subject as obtained in AWB control. In that case, for example, the data constituting the display control table 402 as shown in FIG. 12 may be stored in the MROM 18. The display control table 402 shown in the figure includes, as specific usage conditions, usage conditions related to time (condition 1), usage conditions related to the month of the date (condition 2), usage conditions related to location (condition 3), and usage conditions related to temperature (condition 4). ), Usage conditions for white balance (condition n-1), usage conditions for subject distance (condition n), and the like.

  Even when such a display control table 402 is used, when a shooting mode is set in the scene select mode, a sample image that can be selected (or has a high possibility) is preferentially displayed under the usage conditions at that time. In other words, display of sample images that cannot be selected is prohibited, in other words, only sample images that can be selected (or highly likely) can be displayed. In other words, display of sample images (scene number “3”) in which cherry trees are photographed is prohibited in months other than March and April, or sample images (scene numbers “1”, “n” in winter) in the summer. ”) Is prohibited, sample images relating to the scenes (scene numbers“ 1, 2 ”) are preferentially displayed outdoors during the daytime, and sample images relating to the scenes (scene number“ n ”) during macro photography. -1 ") can be preferentially displayed.

  In the embodiment described above, data of a plurality of sample images constituting the above-described shooting mode tables (FIGS. 3 and 4), shooting condition data corresponding to each sample image, and display control table (FIG. 5, FIG. 9 and FIG. 12), and the case where the operation program for performing the operation related to the scene selection mode has been stored in the MROM 18; It may be configured to be recorded on a possible recording medium, or may be configured to be supplied from another device such as a personal computer or from another device via communication means using the Internet or the like.
