[Description of attention information setting]
In the digital camera of the present embodiment, the degree of the photographer's attention to the shooting scene and subject (important) based on the camera operation at the time of shooting, for example, the zoom operation by the zoom button 102 or the half-press operation of the release button 100 Degree of interest) is automatically calculated, and an attention information setting mode for assigning it to the captured image data as attention degree information is provided. The attention information setting mode is set on a menu screen, for example.

(Automatic setting of importance by zooming)
When the importance is automatically set by a zoom operation, the importance is given according to the zoom amount. For example, if the optical zoom magnification is 3 times at the maximum, they are divided into two stages, the importance is 1 for the zoom magnification 1 to 1.5, and the importance is for the zoom magnification 1.5 to 3. Is 2. Furthermore, when the pressing of the operation unit T is continued even after the zoom magnification reaches three times, the importance is set to 3.

  In the case of a digital camera that has an optical zoom function and a digital zoom function and seamlessly shifts from the optical zoom to the digital zoom, if the operation unit W continues to be pressed even after the optical zoom reaches the maximum magnification, the digital zoom Furthermore, the magnification is enlarged. In that case, the overall magnification including the optical zoom and the digital zoom may be divided into several stages, and importance may be assigned in order from the smallest magnification. As described above, in this embodiment, the higher the zoom magnification, the higher the importance is determined by determining that the photographer is paying attention to the subject. Note that importance may be added when zooming to the telephoto end, not the zoom amount.

(Automatic setting of importance by half-press operation)
In addition to the zoom operation, the importance may be set according to the number of half-press operations until the release button 100 is fully pressed. That is, in a situation where the half-press operation is performed a plurality of times, it is determined that the half-press operation has been performed several times in order to perform careful photographing, and the importance is increased. For example, if the half-press operation is performed once before the release button 100 is fully pressed, the importance is added by +1 each time.

  In addition, the importance of the first operation may be zero, and +1 may be sequentially added after the second operation. Furthermore, the importance level setting by the zoom operation described above and the importance level setting by a half-press operation may be used in combination. The importance level data set here is stored in the DRAM 6 of FIG. 1, and when the release button 100 is fully pressed and shooting is performed, the stored importance level data is cleared.

  The attention information may include the following information in addition to the importance described above. There are the camera posture (azimuth and elevation angle) detected by the posture detection device 13 at the end of the zoom operation, the current position of the camera detected by the GPS device 14, the current date and time, the current time, and a reference image. The reference image is an image based on images (referred to as through images) sequentially taken from the image sensor 2. For example, processing such as lowering the resolution of the captured image data or cutting out the image at the center of the screen is used as the reference image. Such attention information is temporarily stored in the DRAM 6 in association with the above-described importance.

  The captured image data is stored in the memory card 12 as an Exif (Exchangeable image file format) format image file. In an Exif format image file (for example, a JPEG file), additional data such as shooting conditions and thumbnail data is stored as Exif data together with the image data. For example, attention information is stored as one of the Exif data.

  FIG. 3 shows a display example of attention information, which can be displayed on an LCD 8 provided on the camera or a monitor of a PC (personal computer). The example shown in FIG. 3A is a display example when an image is displayed on the LCD 8 or the monitor, and the importance of the attention information is indicated by a star mark at the right corner of the display area of the image. Here, the degree of importance is 2, and two star marks are displayed. Even when a plurality of thumbnail images are displayed, a star mark may be displayed.

  FIG. 3B is a display example when only attention information is displayed in detail. The attention information includes date, position, angle of view, azimuth, elevation angle, reference image, and importance. In this case, since the reference image is attached to the attention information, the photographic scene itself can be easily understood from the reference image as well as the image classification and the search only by the attention information.

(Intentional importance setting)
In setting the importance according to the zoom operation or the half-press operation described above, the importance is automatically set based on the operation amount and the number of operations even if the photographer does not intend. However, the importance level is not only automatically set in this way, but the importance level may be intentionally set for a shooting scene (captured image) to which the photographer should pay attention. As an intentional setting method in a scene to which attention information is to be added, such as a shooting scene that remains in an impression or a shooting scene that is desired to be referred to after shooting, for example, there are the following methods. The photographer once zooms up to the limit of the zoom operation, that is, the tele end of the optical zoom or the tele end including the digital zoom, and further presses the operation unit T. This is not the purpose of zooming up, but an operation performed for adding importance.

  When the CPU 5 detects a further zoom-up operation (depression of the operation unit W) after reaching the tele end, the CPU 5 sets the importance and acquires the above-described attention information. In this case, the frequency (size) of importance is set according to the number of times of pressing and the duration of pressing. For example, the number of times of pressing is the frequency of importance. And the attention information mentioned above with importance is memorize | stored in DRAM6.

  When the importance level is set by pressing down the operation unit T at the tele end, the photographer operates the zoom button 102 to set the zoom magnification according to the shooting scene. Also in this case, +1 may be added to the importance according to the number of half-press operations. Thus, when the importance level is intentionally set, the zoom amount itself is not related to the importance level. Therefore, the importance level may be set by detecting the wide end instead of the tele end.

  Here, the importance is set when the zoom button 102 is further excessively operated at the limit (tele end or wide end) in the zoom operation, but instead of the excessive operation of the zoom button 102, the release button 100 is set. The attention information including the importance may be set when the half-pressed state is continued for a predetermined time or more. In that case, the degree of importance is set by the number of half-press operations.

  Moreover, you may make it perform the intentional setting of the importance using the limit in another operation. In a mode in which the AF area can be manually selected at the time of shooting, the AF area selection operation function is assigned to the select button 104. However, the importance may be set by operating the select button 104. As a setting method in this case, for example, the operation 104a to 104d of the select button 104 is operated to move the selected state of the AF area to one of the upper, lower, left and right AF areas. That is, the selected area of the AF area is moved by the limit. For example, the AF area 80c is selected by operating the operation unit 104b.

  Further, the operation unit 104b is pressed in that state. When the CPU 5 detects further pressing of the operation unit 104b, the CPU 5 sets the importance level. Also in this case, the degree of importance is set according to the number of times of pressing. Then, the CPU 6 temporarily stores other attention information in the DRAM 6 together with the set importance. After that, if a photographing operation is performed, the CPU 5 adds attention information (including importance) to the image data acquired by photographing and records it in the flash memory 7 or the memory card 12.

(Set importance to partial area)
In the above-described importance setting, the importance is set for the entire image. However, the importance may be added to a specific partial region of one image. For example, a case will be described where importance is added to a person and a background mountain in a shooting scene as shown in FIG. First, the person is zoomed up to the telephoto end, and the operation unit T is pressed as many times as the degree of importance. As a result, attention information (1) as shown in FIG. 4A is set and stored in the DRAM 5.

  Next, after the zoom is once moved to the wide side, the background mountain is zoomed up to the telephoto end, and the operation unit T is pressed the number of times corresponding to the importance. As a result, attention information (2) as shown in FIG. 4B is set and stored in the DRAM 5. Thereafter, when shooting is performed with the zoom amount returned to the state of FIG. 3A, attention information shown in FIGS. 4A and 4B is added to the image data and recorded in the flash memory 7 or the memory card 12. The That is, two pieces of attention information are embedded in the tag information of the image file. By referring to the reference images shown in FIGS. 4A and 4B, it can be easily understood which region in the captured image has the importance.

  Further, when an image is displayed on a monitor such as the LCD 8, as shown by broken lines L1 and L2 in FIG. 5, the frame shape of the reference image may be displayed superimposed on the display image. With this frame, the attention area can be seen at a glance. You may make it display the star mark which shows importance at the upper right of the frames L1 and L2.

  In setting the importance level for the partial area, the importance level may be set by detecting the wide end instead of the tele end. Also, the importance may be set by detecting the limit (up / down / left / right ends) of AF area selection by the operation of the select button 104 instead of the zoom operation.

(Description of attention information setting operation)
FIG. 6 is a flowchart for explaining an example of attention information setting accompanying the photographing operation. Here, a case where importance is set and attention information is given when a tele end or a wide end is detected by a zoom operation will be described as an example. A processing program for this operation is stored in advance in the ROM 16 and is executed by the CPU 5. The process shown in FIG. 6 starts when the camera is set to a shooting mode for shooting an image. In general, in a digital camera, when the power is turned on, the camera is ready to shoot (shooting mode). Therefore, the process of FIG.

  In step S1, the CPU 5 detects the zoom position and acquires the detection data. In step S2, it is determined whether or not the detected zoom position is at the tele end or the wide end. If it determines with YES in step S2, it will progress to step S3, and if it determines with NO, it will progress to step S6. In step S3, the importance is set according to the number of operations of the operation units T and W at the tele end or the wide end. Next, in step S4, various attention information is acquired. In step S5, attention information including importance is stored in the DRAM 5.

  In step S6, the CPU 5 determines whether or not a photographing operation, that is, a full pressing operation of the release button 100 by the photographer has been performed. If it is determined in step S6 that a photographing operation has been performed, the process proceeds to step S7, and if it is determined NO, the process returns to step S1. When returning to step S1, the processes from step S1 to step S6 are performed again. When the operation to the telephoto or wide end is performed, the second attention information (2) as described with reference to FIG.

  On the other hand, when the process proceeds from step S6 to step S7, the CPU 5 reads the attitude and position detected by the attitude detection device 13 and the GPS device 14. In step S8, the position and orientation data of the attention information is compared with the position and orientation data detected in step S7. When there is attention information whose position difference is smaller than a predetermined position threshold and whose posture (for example, elevation angle) is smaller than the predetermined posture threshold, the process proceeds from step S8 to step S9. On the other hand, if it is determined that the detected value is larger than the threshold value for any attention information, the process proceeds from step S8 to step S10.

  In the processing in steps S7 and S8 described above, when the change in the position or orientation of the camera is smaller than the threshold value, the attention information acquired in the processing in steps S3 to S5 is related to the captured image. It was judged. In other words, if the position and orientation at the time of shooting have changed significantly compared to those at the time of attention acquisition, it is determined that the shooting scene at the time of attention acquisition is different from that at the time of shooting and attention information is given. I didn't do it.

  Here, both the position and the posture are compared, but the determination may be made by comparing only the position. Even if there is no position or orientation item in the attention information, the position or orientation detection value is acquired in step S4 for determination in step S8. Further, instead of comparing the position and orientation, the elapsed time from the acquisition of each piece of attention information to the time of shooting may be compared with a threshold value, and the attention information within the threshold value may be added to the image file.

  When the process proceeds to step S9, an image file to which only attention information within the threshold is added is generated, and the data is recorded in the flash memory 7 or the memory card 12 in step S11. Although not shown, attention information (including importance) stored in the DRAM 5 is cleared after recording in step S11. On the other hand, if the process proceeds to step S10, a normal image file without attention information is generated, and the process proceeds to step S11 to record the data in the memory card 12.

  In step S <b> 12, the CPU 5 determines whether or not the shooting mode has been detected as being ended. When the camera is switched from the shooting mode to the playback mode or the power switch is turned off to end the shooting mode, the series of processing shown in FIG. 6 ends. On the other hand, if NO is determined in step S12, the process returns to step S1.

(Add attention information during image playback)
In the flowchart shown in FIG. 6, attention information is set before the photographing operation. However, attention information may be added when the image is reproduced after photographing. For example, importance may be set at the time of preview immediately after shooting, or an image may be reproduced and displayed on the LCD 8 after shooting to add attention information. Since the preview time is short, the importance may be set only by pressing the operation unit 104e of the select button 104 instead of the zoom button 102 so that the importance can be set quickly.

  When setting the importance after shooting, the user zooms up to the maximum magnification that is the limit of zoom display. When the CPU 5 recognizes that the maximum magnification has been reached, it sets the importance for the image and records it. Also in this case, the degree of importance is set by the number of times the operation unit T of the zoom button 102 is pressed after the maximum magnification.

  When the image is reproduced and displayed on the LCD 8 and the importance level is set, the time and position may have changed greatly from the time of shooting, so the items of attention information include shooting date and time, shooting position, importance level, reference The current date and time when attention information is set is added to the image. In addition, when setting importance by zoom display, a plurality of attention information is added by performing zoom display in different areas, and images of different areas that have been zoomed up are cut out for each reference image. Become. That is, the importance is added to the partial area.

As described above, in this embodiment, the degree of importance can be added to an image by operating the zoom button 102, the select button 104, or the like. This addition of importance may be automatically performed according to the zoom amount or may be performed by a user's conscious operation. When it is automatically performed, the photographer adds importance by performing the same photographing operation as before, and does not bother the photographer. On the other hand, when the importance level is added consciously, the photographer's intention regarding the attention level can be sufficiently reflected. In any case, by adding the attention information including the above-mentioned importance to the image file, this attention information is very useful when classifying or searching for images at a later date, and if necessary, the image is quickly found. be able to.
Further, only the attention information may be recorded as one independent file in the same manner as the captured image file. At this time, a reference image is used as the image data.

  In the above-described embodiment, a lens-integrated digital camera has been described as an example. However, the present invention can be similarly applied to a single-lens reflex digital camera. In that case, importance may be set by operating a zoom ring provided in the lens barrel. Furthermore, the present invention is not limited to a camera, but can be applied to any device having an imaging function such as a camera-equipped mobile phone, a digital field scope, or digital binoculars. In addition, the present invention is not limited to the above embodiment as long as the characteristics of the present invention are not impaired.
