Hereinafter, a digital camera, an image processing apparatus, and an image control program according to embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram of a digital camera 101 according to the first embodiment. The camera 101 operates according to a program stored in advance in the CPU 102 and controls each unit of the camera 101 via a system bus 104. The user gives an operation instruction to the CPU 102 by pressing an operation button on the operation panel 103.

  The camera 101 of the present embodiment has three types of image modes. The image mode is the image quality obtained by changing the compression ratio and the three image quality preset by combining the image size parameters (high quality (FINE), standard (NORMAL), economy (ECONOMY)) Thus, the number of images that can be stored in the memory card 114 differs depending on the setting. For example, when the storage capacity of the memory card 114 is 256 MB (megabytes), it is possible to store about 70 images in the high image quality mode, 195 images to be burned in the standard mode, and about 305 images in the economy mode. When the above-mentioned number of shots is converted into the required storage capacity per image, it is about 3.66 MB in the high image quality mode, about 1.31 MB in the standard mode, and about 0.84 MB in the economy mode. However, it differs slightly depending on the image to be taken.

  Light from the subject incident from the lens 105 forms an image on the image sensor 106 and is converted into an electrical signal. The analog image signal converted into an electrical signal is subjected to noise removal and amplification by an analog front end (AFE) 107 and converted to digital image data by an analog / digital conversion unit (A / D) 108. The image data converted by the A / D 108 is temporarily stored in the RAW memory 109 as RGB raw data (RAW data) of the captured image.

The image processing circuit 110 reads RAW data from the RAW memory 109, performs interpolation processing, conversion processing from RGB data to luminance color difference (YCrCb) data, and the like, and temporarily stores them in the memory 111. The image temporarily stored in the memory 111 is output to the display circuit 115 and displayed on the liquid crystal monitor 116.
The image compression circuit 112 reads YCrCb data from the memory 111 and performs image compression processing such as JPEG standard. At this time, the compression rate is varied according to a preset image mode.

  The image data processed by the image compression circuit 112 is stored in the memory card 114 connected via the memory card IF 113. Note that data input / output between the RAW memory 109, the memory 111, the image processing circuit 110, and the image compression circuit 112 is performed via the system bus 104 and controlled by the CPU. Hereinafter, unless otherwise specified, the CPU 102 performs input / output of each data and control of each circuit, and description of the data via the system bus 104 when inputting / outputting data between these circuits is omitted.

  When the user operates the operation panel 103 to instruct the CPU 102 to display the compressed image data stored in the memory card 114, the CPU 102 reads the image data from the memory card 114 via the memory card IF 113. The image data compressed by the image compression circuit 112 is decompressed and converted into YCrCb data or RGB data, and is temporarily stored in the memory 111. The image temporarily stored in the memory 111 is output to the display circuit 115 and displayed on the liquid crystal monitor 116.

  In addition, the digital camera 101 according to the present embodiment adds information indicating importance to a captured image and stores the information in the memory card 114. For example, as shown in FIG. 2A, three types of importance A, B and C are set and stored together with the image data. Here, the importance level A indicates that deletion is impossible, and the importance level C indicates that deletion is possible. The importance B indicates that the image mode can be changed. For example, an image shot in the high quality mode is changed to the standard mode or the economy mode, or an image shot in the standard mode is changed to the economy mode. Indicates that it may be changed.

Next, an example of a method for setting the importance will be described with reference to FIGS. FIG. 3 is a flowchart of importance setting, and a series of these processes is performed according to a program stored in advance in the CPU 102.
(Step S201) A subroutine for importance setting processing is started. This subroutine is periodically called from the main routine, for example.
(Step S202) It is determined whether or not the shutter has been pressed, that is, whether or not an image has been shot. If an image has been shot, the process proceeds to step S203. If no image has been shot, the process proceeds to step S214. To return to the main routine.
(Step S <b> 203) When a new image is taken, an importance setting screen is displayed on the liquid crystal monitor 116. FIG. 4 shows this state, and the captured image and the importance (A, B, C) are displayed on the screen 116 a of the liquid crystal monitor 116 of the digital camera 101.
(Step S204) Importance is selected. In FIG. 4, one of the importance levels (A, B, C) displayed on the screen 116a is selected with the cursor 203. The importance level A is selected on the screen 116a. Reference numeral 201 denotes a power button, and 202 denotes a shutter button.
(Step S205) The cursor 203 is moved to select other than the importance level A. For example, the state where the importance level B is selected is as shown in the screen 116b, and the state where the importance level C is selected is as shown in the screen 116c.
(Step S206) When determining the selected importance, the OK button on the screen is selected with the cursor 203 and determined. If the OK button is not selected, the process returns to step S205 to repeat the importance selection process.
(Step S207) When the importance of the photographed image is determined, the importance setting processing is terminated.

In the above description, the importance level is set every time an image is captured. However, for example, the captured image can be displayed on the screen 116a in FIG. May be set, or the importance of an image to which importance has already been added may be changed.
In this embodiment, the importance is set manually by the user. However, for example, as shown in FIG. 4A, when the photographed image is a camera shake image, the importance is automatically set. The importance may be set to C. Whether or not the image is a camera shake image can be detected by a camera shake sensor used in a general camera.

  Note that, as shown in FIG. 2B, four types of importance A, B, C, and D may be set. In this case, the reduction of the image capacity can be set in two stages, and is the same as FIG. 2A except that the importance is four types. All you need to do is select the type. Even when the types of importance are further increased, the same can be realized.

As described above, the digital camera 101 according to the present embodiment adds information indicating importance to a captured image and stores the information in the memory card 114.
Next, processing when the storage capacity of the memory card 114 is insufficient will be described with reference to the flowchart of FIG. Note that the series of processing is performed by the CPU 102 according to a program stored in advance.
(Step S301) The processing when the storage capacity of the memory card 114 is insufficient is started. This process may be performed automatically, for example, when the digital camera 101 is turned on, before shooting, or after shooting, or may be performed manually by the user. It doesn't matter.
(Step S302) It is determined whether or not the storage capacity of the memory card 114 is sufficient when shooting is performed in the current image mode. For example, when the current image mode is the high image quality mode, approximately 3.66 MB is required to capture one image. Therefore, for example, when the remaining storage capacity of the memory card 114 is 2 MB, the image is captured in the high image quality mode. I can't. If the storage capacity is insufficient, the process proceeds to step S313, and if the storage capacity is insufficient, the process proceeds to step S303. It should be noted that it is preferable that the criterion (predetermined value) for determining whether or not the storage capacity is sufficient has some margin with respect to the standard capacity per one image mode to be photographed. For example, when the set image mode is the high image quality mode, 3.8 MB with a margin is set as a predetermined value, and when the remaining storage capacity is equal to or less than the predetermined value, it is determined that the storage capacity is insufficient. In the above case, it is determined that the storage capacity is sufficient.

In this step, the user may be informed of the captured image mode, the number of images that can be captured, the remaining memory capacity, and the like set in the digital camera 101. For example, as shown in FIG. 6A, the user looks at the screen of the liquid crystal monitor 116 and confirms that the set captured image mode is FINE, the number of shootable images is 3, and the remaining memory capacity is 12 MB. You can know before shooting.
(Step S303) A processing mode is selected. The digital camera 101 has two processing modes: priority of the captured image mode and reduction of the captured image mode capacity. Priority is given to the shot image mode, which means that if the storage capacity is insufficient, an image with a low importance is deleted from the image stored in the memory card 114 or the capacity is reduced, and a new image is set. In this mode, a process for securing a capacity that can be photographed in the mode is performed. In addition, the reduced captured image mode is a mode in which when the storage capacity is insufficient, the captured image mode is changed to the reduced capacity mode so that a new image can be captured with the current remaining storage capacity. is there. For example, when the remaining storage capacity is 2 MB, shooting is not possible in the high image quality mode, but shooting can be performed by changing to the standard mode or economy mode.

For example, as shown in FIG. 6B, the user views the screen of the liquid crystal monitor 116 and selects a processing mode with the cursor 203. Alternatively, as shown in FIG. 6C, a change button for reducing the captured image mode capacity may be displayed on the screen of the liquid crystal monitor 116 and selected with the cursor 203.
In addition, in the case of having an auto mode for automating the settings of the digital camera 101, selection of a setting for giving priority to the image mode to be photographed and a setting for reducing the capacity of the image mode to be photographed is based on a preset image mode for photographing. Since either the priority setting or the image mode to be photographed is automatically selected as the setting for reducing the capacity, the process proceeds to step S304 without executing step S303.
(Step S304) It is determined whether or not the photographed image mode priority is selected in step S303. If the processing mode is priority to the captured image mode, the process proceeds to step S307, and if the captured image mode has a small capacity, the process proceeds to step S305.
(Step S305) If the image mode is set to the standard mode, it is determined whether or not photographing is possible. For example, when the remaining storage capacity of the memory card 114 is 2 MB, shooting is possible in the standard mode, but shooting is not possible when it is 1 MB. If shooting is possible, the process proceeds to step S314, and if shooting is not possible, the process proceeds to step S306.
(Step S306) If the image mode is set to the economy mode, it is determined whether or not photographing is possible. For example, if the remaining storage capacity of the memory card 114 is 1 MB, shooting can be performed in the economy mode, but if 0.5 MB, shooting cannot be performed. If shooting is possible, the process proceeds to step S314. If shooting is not possible, the process proceeds to step S307.
(Step S307) It is determined whether there is image data that can be compressed (reduced in capacity) in the captured image stored in the memory card 114. In other words, the determination is made by looking at the importance added to the image data and stored. For example, the image data to which the importance level B that can change the image mode is added is searched. If there is image data to which importance B is added, the process proceeds to step S308, and if not, the process proceeds to step S310.
(Step S308) If there is an image with importance B added to the memory card 114, if the image data is reduced in capacity, it is possible to secure a storage capacity capable of capturing a new image in the current captured image mode. Determine whether. For example, if the image to which the importance level B is added is an image in the high quality mode, the storage capacity of about 2.32 MB is increased by reducing the capacity to the standard mode. However, even if the capacity is reduced, if the remaining capacity of the memory card 114 is only 1 MB, the total amount is only about 3.32 MB, and shooting in the high image quality mode is not possible. If the photographing capacity can be secured by reducing the capacity, the process proceeds to step S309, and if not, the process proceeds to step S310. In this case, if there are a plurality of images to which the importance level B is added, the free space may be increased by reducing the capacity of the plurality of images to the standard mode.
(Step S309) The capacity of the image with the importance B is reduced. That is, the capacity is reduced to the standard mode in the high image quality mode, and the capacity is reduced to the economy mode in the standard mode. For example, when images as shown in FIG. 7 are stored, the images c and f of importance B are reduced in capacity. At this time, if it is possible to shoot only by reducing the volume of either the image c or the image f, for example, even if the importance B is the same, the image f having a large volume is preferentially reduced in volume. You may make it carry out, and you may make it reduce the capacity | capacitance of the image c of an old date preferentially.

Note that the capacity may be suddenly reduced from the high quality mode to the economy mode. However, in this case, as shown in FIG. 2 (b), it is preferable to set how far the capacity can be reduced by dividing the importance B and C.
In addition, as shown in FIG. 8 (a), when the volume is reduced, the user can confirm the image to be reduced in capacity, as shown in FIG. The mode may be displayed so that an image to be reduced in capacity can be selected. In this way, if the user's mind changes and the image is not desired to be reduced in size, it is not necessary to reduce the size. If there are many candidate images, click the selection mark below each image while pressing the previous image button or the next image button with the cursor 203 in FIG. 6 or press the all selection button to determine the image to be reduced in capacity. And press the small capacity execution button. However, when the image to be reduced in volume is changed in this way, it is necessary to return to step S308 in order to reconfirm whether or not the shooting capacity can be secured.
(Step S310) It is determined whether there is image data that can be deleted in the captured images stored in the memory card 114. At this time, determination is made based on the importance level information added to and stored in the image data, and for example, it is searched whether there is image data to which the importance level C is added. If there is image data to which importance C is added, the process proceeds to step S311; otherwise, the process proceeds to step S312.
(Step S311) If there is an image to which importance C is added to the memory card 114, it is determined whether or not the image can be deleted to secure a storage capacity for taking a new image in the current image mode. . For example, if the image to which importance C is added is an image in the high quality mode, the storage capacity of about 3.66 MB can be secured by deleting the image. However, in the case of an economy mode image, even if it is deleted, only about 0.84 MB is increased. Therefore, if the remaining capacity of the memory card 114 is only 2 MB, shooting in the high image quality mode cannot be performed. If it can be deleted and the shooting capacity can be secured, the process proceeds to step S313; otherwise, the process proceeds to step S312. In this case, if there is an image to which a plurality of importance levels C are added, the free space may be increased by deleting the plurality of images.
(Step S 312) If the shooting capacity cannot be secured by any processing, “insufficient shooting capacity” is displayed on the liquid crystal monitor 116, and the user can secure free space manually or replace the memory card 114. Prompt.
(Step S313) The image to which importance C is added is deleted. For example, when images as shown in FIG. 7 are stored, the image a and the image d having the importance C are deleted. At this time, if it is possible to shoot only by deleting either the image a or the image d, for example, the image a having a large capacity is preferentially deleted even at the same importance level C. Alternatively, the image d with an old date may be deleted preferentially.

In addition, when deleting an image, as shown in FIG. 8B, an image to be deleted is displayed by displaying a deletion candidate image on the screen of the LCD monitor 116 so that the user can confirm the image to be deleted. May be selected. In this way, if the user changes his mind and the image is not desired to be deleted, the image is not deleted. If there are many candidate images, click the selection mark below each image while pressing the previous image button or the next image button with the cursor 203 in FIG. 6 or press the select all button to determine the image to be deleted. Press the delete execution button. However, when the image to be deleted is changed in this way, it is necessary to return to step S311 in order to reconfirm whether or not the photographing capacity can be secured.
(Step S314) Since the photographing capacity is secured, “capturing possible” is displayed on the liquid crystal monitor 116 to notify the user that photographing is possible.
(Step S315) The captured image processing mode is terminated.

  In the present embodiment, the captured image is processed when the storage capacity of the memory card 114 is insufficient. However, only when the captured image processing mode is provided and this setting is turned ON, the processing shown in FIG. A process may be executed, and if it is OFF, the process may not be performed. In this embodiment, the importance level is set for all captured images regardless of whether the captured image processing mode is ON or OFF. However, when the captured image processing mode is OFF, the importance level is set. It is also possible not to perform the setting. In this case, there is image data for which the importance level is not set. However, when the captured image processing mode is turned on later, the image data for which the importance level is not set is the same as that cannot be deleted. By considering the importance level, it is possible to perform the same processing.

  In the present embodiment, when no image can be shot in the image mode in which the remaining capacity of the memory card 114 is set, the setting of the image mode to be shot is changed or the captured image is reduced in capacity. Alternatively, the processing is performed to secure a storage capacity capable of capturing at least one image by deleting, but the image is captured when the number of images that can be captured with the remaining capacity of the memory card 114 is two or three. The number of images that can be captured may always be ensured by a certain amount or more by changing the setting of the image mode, or by reducing or deleting the captured image.

  As described above, the digital camera 101 according to the present embodiment sets the importance of the captured image, and sets the priority to the image mode to be captured and the image to be captured when the memory card 114 has a small capacity. Since the mode can be selected to reduce the capacity, there is no chance of missing a photo opportunity. In addition, since the image to be deleted or compressed can be confirmed, it is possible to prevent regret after the image file is deleted or compressed.

  In step S304 in the flowchart of FIG. 5, if the captured image mode has priority, the captured image mode in steps S305 and S306 is not reduced in capacity. However, even if the captured image mode has priority, the captured image mode is captured. When the capacity becomes insufficient, the captured image mode may be set so that priority is not given, and the processing after step S304 may be executed again. In this case, if the shooting capacity is insufficient even if the process for prioritizing the captured image mode is performed, the captured image mode is changed to a setting that does not prioritize, and the captured image mode is reduced in capacity.

  In the flowchart of FIG. 5, first, a process for reducing the capacity of an image mode to be taken is performed (steps S305 and S306), and then, if there is a compressible image, a process for compressing and reducing the capacity (steps S308 and S309). ) Or when the capacity cannot be ensured even if the capacity is reduced, the process of deleting images that can be deleted (steps S311 and S313) is performed in order. First, reduce the capacity of the recorded image, then reduce the capacity of the image mode to shoot when the capacity is still insufficient, and then delete the image that can be deleted if the capacity is still insufficient You may perform each process in order. Alternatively, priority can be set in advance for three processes: a process for reducing the image mode to be captured, a process for compressing and reducing the capacity if there is a compressible image, and a process for deleting an image that can be deleted. It doesn't matter if you do. In this case, the processing is executed from the processing with higher priority, and when the capacity for photographing cannot be secured, the priority is lowered in order.

  Further, an intermediate setting mode (ambiguous setting mode) may be provided. This is a mode for securing a capacity by deleting or reducing the capacity of a less important image and also reducing the capacity of the image mode for capturing when the capacity for capturing is insufficient. For example, in the flowchart of FIG. 5, when the image mode to be captured can be captured by reducing the capacity to the economy mode, the recorded image is not compressed or deleted. On the other hand, in the ambiguous setting mode, the image mode to be shot is reduced in capacity from the high image quality mode to the standard mode, and the insufficient capacity is dealt with by compressing or deleting the recorded image. At this time, a process for reducing the image mode to be captured so that the capacity is closest to the shortage capacity, a process for compressing and reducing the capacity if there is a compressible image, and a deletion are possible. A combination of three processes for deleting an image may be selected and executed.

(Second Embodiment)
Although the digital camera has been described in the first embodiment, it may be an image processing apparatus that inputs image data and stores it in a recording medium or an image control program of a personal computer.
For example, the present invention can be applied to software for mounting an image stored in a memory card or the like on a personal computer and copying the image data on the memory card to a storage medium such as a hard disk of the personal computer. That is, when the image data of the memory card is input to the hard disk of the personal computer, importance is added to the image data. As described with reference to FIGS. 3 and 4, the addition of the importance can be realized in the same manner by a program of a personal computer.

  For example, when image data is copied from a number of memory cards to the hard disk of a personal computer, the remaining capacity of the hard disk becomes less than a predetermined value, but as with the digital camera 101, the image quality of the input image data The setting that gives priority to the image quality and the setting that reduces the volume of the input image data can be selected. In the setting that gives priority to the image quality of the input image data, it is important to select from among the image data stored on the hard disk. In the case of setting to reduce the capacity of the input image data by deleting the image or reducing the capacity of the low-frequency image, processing for reducing the capacity of the input image data is performed.

  By processing in this way, even when the remaining capacity of the hard disk is reduced, the image data on the memory card can be copied to the hard disk without remaining.
