Description

The present invention relates to a display control device that controls to display an erase menu for image erasure.

In recent years, in image pickup devices including cameras and the like, a large number of images have been generated in one shooting due to an improvement in the processing speed of continuous shooting. In addition, with the increase in the capacity of media such as memory cards, it has become possible to store a large amount of captured images on the media.

Since there are many failed images and unnecessary images in a large number of images in the media, it is common for the user to perform an operation of discarding unnecessary images from the media (erasing images). In order to erase an image, the user switches to a mode for viewing the image (reproduction mode) in the image pickup apparatus, and then selects the image to be erased. Then, press the operation button (erase button) for giving an erase instruction, and when the confirmation screen (erase menu) as to whether or not to erase is displayed, the decision operation (for example, select "erase" on the confirmation screen). Will be done. In the case of an image pickup device, in the erase menu, "do not erase" is often the initial focus, and it is necessary to move the options in order to select "erase", which requires an extra operation turn. Performing this operation for each image is not preferable because it increases the time and the number of operations. To solve this, there is a method to set the initial focus of the erase menu to the "erase" side in advance. With this setting, when the menu is displayed by pressing the erase button, the focus is on "erase", so after pressing the erase button, you can erase the image by pressing the enter button once. It will be possible. On the other hand, in recent image pickup devices, it is possible to simultaneously store JPEG image data and RAW image data before JPEG compression in a medium with a single shooting operation. That is, it is possible to save a plurality of images in different formats (formats) for the same scene. Further, in these image pickup devices, when viewing an image in the playback mode, since it is an image of the same scene, it is common to display only one image (in the case of a RAW + JPEG image, only the JPRG image is displayed). It is a target. Here, there may be a use case where you want to erase only the image in one format in order to save the media capacity. At that time, when the erase button is pressed, a menu with a plurality of options such as "erase only the image in one format" or "erase the image in both formats" is displayed. Then, there is known a method of erasing an image in a target format by performing a determination operation on the menu (Patent Document 1).

Japanese Unexamined Patent Publication No. 2005-8050

However, in the case of the method described in Patent Document 1, it is difficult to say that the operability is good because the number of turns of the operation of moving the options in the erase menu increases. In order to solve this, there is also a method of setting the option to be selected as the initial focus in advance. If a similar erase menu is displayed for an image recorded in multiple formats and an image recorded only in a single format, or if the initial focus is determined in the same way, the image is erased unintentionally by the user. May be done.

Therefore, according to the present invention, when erasing an image recorded in a plurality of formats, it is possible to quickly erase the image in the desired format by setting the initial selection, and further, it is possible to prevent the image from being erased by mistake. The purpose is to provide a possible device.

Therefore, the display control device of the present invention is used.
A means for selecting an image from a plurality of images recorded on a recording medium, including images recorded in both the first format and the second format, or images recorded only in the first format. , The image selected by the selection means is selected according to the reception means for receiving the deletion instruction, the display control means for controlling the display of the deletion menu in response to the deletion instruction, and the item selected in the deletion menu. Both the first format image and the second format image are erased by the erasing means for erasing the image selected by the means from the recording medium and the item initially selected in the erasing menu displayed in response to the erasing instruction. The display control means has an item for erasing, an item for erasing the image of the first format, and a setting means for setting from a plurality of items including an item for canceling the erasure, and the display control means erases according to the erasing instruction. When the menu is displayed, if the image selected by the selection means is an image recorded only in the first format, the item for erasing the image in the first format is set as the initial selection item by the setting means. Even if it is, the feature is that the item for canceling the erasure is controlled to display the initially selected erasure menu, not the item for erasing the image of the first format.

According to the present invention, when erasing an image recorded in a plurality of formats, it is possible to quickly erase the image in the desired format by setting the initial selection, and further prevent the image from being erased by mistake. Is possible.

In FIG. 2, the photographing lens 103 is a lens group including a zoom lens and a focus lens. The shutter 101 is a shutter having an aperture function. The image pickup unit 22 is an image pickup device composed of a CCD, a CMOS element, or the like that converts an optical image into an electric signal. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the image pickup unit 22 into a digital signal. The barrier 102 covers the imaging system including the photographing lens 103 of the digital camera 100 to prevent the imaging system including the photographing lens 103, the shutter 101, and the imaging unit 22 from being soiled or damaged.

The image processing unit 24 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 23 or the data from the memory control unit 15. Further, in the image processing unit 24, a predetermined calculation process is performed using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result. As a result, TTL (through-the-lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-flash) processing are performed. Further, the image processing unit 24 performs a predetermined calculation process using the captured image data, and also performs a TTL method AWB (auto white balance) process based on the obtained calculation result.

The output data from the A / D converter 23 is written directly to the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the image pickup unit 22 and converted into digital data by the A / D converter 23, and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, moving images for a predetermined time, and audio.

Further, the memory 32 also serves as a memory (video memory) for displaying an image. The D / A converter 13 converts the image display data stored in the memory 32 into an analog signal and supplies it to the display unit 28. In this way, the image data for display written in the memory 32 is displayed by the display unit 28 via the D / A converter 13. The display unit 28 displays on a display such as an LCD according to the analog signal from the D / A converter 13.

It functions and can display through images (live view display).

The non-volatile memory 56 is a memory as a recording medium that can be electrically erased and recorded, and for example, EEPROM or the like is used. The non-volatile memory 56 stores constants, programs, and the like for the operation of the system control unit 50. The program referred to here is a computer program for executing various flowcharts described later in this embodiment.

The system control unit 50 is a control unit having at least one processor and controls the entire digital camera 100. By reading the program recorded in the non-volatile memory 56 described above and executing the program, each process of the present embodiment described later is realized. RAM is used for the system memory 52. In the system memory 52, constants and variables for the operation of the system control unit 50, a program read from the non-volatile memory 56, and the like are expanded. The system control unit 50 also controls the display by controlling the memory 32, the D / A converter 13, the display unit 28, and the like.

The system timer 53 is a time measuring unit that measures the time used for various controls and the time of the built-in clock.

The mode changeover switch 60, the shutter button 61, and the operation unit 70 are operation means for inputting various operation instructions to the system control unit 50.

The mode changeover switch 60 switches the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image shooting mode, a playback mode, and the like. The modes included in the still image recording mode include an auto shooting mode, an auto scene discrimination mode, a manual mode, an aperture priority mode (Av mode), and a shutter speed priority mode (Tv mode). In addition, there are various scene modes, program AE modes, custom modes, etc. that are shooting settings for each shooting scene. The mode changeover switch 60 directly switches to any of these modes. Alternatively, after switching to the shooting mode list screen once with the mode changeover switch 60, one of the displayed plurality of modes may be selected and switched using another operating member. Similarly, the moving image shooting mode may include a plurality of modes.

The first shutter switch 62 is turned on by a so-called half-pressing (shooting preparation instruction) during the operation of the shutter button 61 provided in the digital camera 100, and the first shutter switch signal SW1 is generated. The first shutter switch signal SW1 starts operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-flash) processing.

The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, that is, when the shutter button 61 is fully pressed (shooting instruction), and the second shutter switch signal SW2 is generated. The system control unit 50 starts a series of shooting processes from reading the signal from the image pickup unit 22 to writing the image data to the recording medium 200 by the second shutter switch signal SW2.

Each operation member of the operation unit 70 is assigned a function as appropriate for each scene by selecting and operating various function icons displayed on the display unit 28, and acts as various function buttons. Examples of the function button include an end button, a back button, an image feed button, a jump button, a narrowing down button, an attribute change button, and the like. For example, when the menu button is pressed, various configurable menu screens are displayed on the display unit 28. The user can intuitively make various settings by using the menu screen displayed on the display unit 28 and the up / down / left / right four-direction buttons and the SET button 145. The four-way button includes an up button 141, a down button 142, a left button 143, and a right button 144.

The controller wheel 73 is a rotation-operable operation member included in the operation unit 70, and is used when instructing a selection item together with a direction button. When the controller wheel 73 is rotated, an electrical pulse signal is generated according to the amount of operation, and the system control unit 50 controls each unit of the digital camera 100 based on this pulse signal. From this pulse signal, it is possible to determine the angle at which the controller wheel 73 is rotated, the number of rotations, and the like. The controller wheel 73 may be any operation member as long as it can detect the rotation operation. For example, the controller wheel 73 itself may be a dial operation member that rotates in response to a user's rotation operation to generate a pulse signal. Further, the operation member including the touch sensor may be one that does not rotate the controller wheel 73 itself and detects the rotational movement of the user's finger on the controller wheel 73 (so-called touch wheel).

The power supply control unit 80 includes a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power supply control unit 80 controls the DC-DC converter based on the detection result and the instruction of the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period.

The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F18 is an interface with a recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and is composed of a semiconductor memory, an optical disk, a magnetic disk, or the like.

The communication unit 54 is connected by a wireless or wired cable to transmit and receive video signals, audio signals, and the like. The communication unit 54 can also be connected to a wireless LAN (Local Area Network) or the Internet. The communication unit 54 can transmit an image (including a through image) captured by the image pickup unit 22 and an image recorded on the recording medium 200, and can also receive image data and other various information from an external device. can.

The posture detection unit 55 detects the posture of the digital camera 100 with respect to the direction of gravity. Based on the posture detected by the posture detection unit 55, whether the image taken by the image pickup unit 22 is an image taken by holding the digital camera 100 horizontally or an image taken by holding the digital camera 100 vertically. It is possible to distinguish. The system control unit 50 can add orientation information according to the posture detected by the posture detection unit 55 to the image file of the image captured by the image pickup unit 22, or can rotate and record the image. As the posture detection unit 55, an acceleration sensor, a gyro sensor, or the like can be used.

As one of the operation units 70, there is a touch panel 70a capable of detecting contact with the display unit 28. The touch panel 70a and the display unit 28 can be integrally configured. For example, the touch panel 70a is configured so that the light transmittance does not interfere with the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel 70a and the display coordinates on the display unit 28 are associated with each other. This makes it possible to configure a GUI (graphical user interface) as if the user can directly operate the screen displayed on the display unit 28. The system control unit 50 can detect the following operations or states on the touch panel 70a.
-A finger or pen that has not touched the touch panel 70a has newly touched the touch panel 70a. That is, the start of touch (hereinafter referred to as touch-down).
-The touch panel 70a is in a state of being touched with a finger or a pen (hereinafter referred to as touch-on).
-Movement while touching the touch panel 70a with a finger or a pen (hereinafter referred to as Touch-Move).
-The finger or pen that was touching the touch panel 70a was released. That is, the end of touch (hereinafter referred to as touch-up (Touch-Up)).
-A state in which nothing is touched on the touch panel 70a (hereinafter referred to as touch-off).

When touchdown is detected, it is also detected that it is touch-on. After touchdown, touch-on usually continues to be detected unless touch-up is detected. Touch move is also detected when touch on is detected. Even if touch-on is detected, touch move is not detected unless the touch position is moved. After it is detected that all the fingers and pens that have been touched are touched up, the touch off is performed.

These operations / states and the position coordinates that the finger or pen is touching on the touch panel 70a are notified to the system control unit 50 through the internal bus, and the system control unit 50 determines which on the touch panel 70a based on the notified information. It is determined whether such a touch operation has been performed. Regarding the touch move, the moving direction of the finger or pen moving on the touch panel 70a can also be determined for each vertical component / horizontal component on the touch panel 70a based on the change in the position coordinates. When it is detected that the touch move is performed for a predetermined distance or more, it is determined that the slide operation has been performed. An operation such as touching a finger on the touch panel, moving it quickly for a certain distance, and then releasing it is called flicking. In other words, flicking is an operation of swiftly tracing on the touch panel 70a as if flicking with a finger. It can be determined that a flick has been performed when it is detected that the touch move is performed at a predetermined speed or more over a predetermined distance and the touch-up is detected as it is (it can be determined that there was a flick following the slide operation). Further, a touch operation in which a plurality of points (for example, two points) are touched at the same time to bring the touch positions closer to each other is called a pinch-in, and a touch operation to move the touch positions away from each other is called a pinch-out. Pinch out and pinch in are collectively called pinch operation (or simply pinch). The touch panel 70a may be any of various touch panels such as a resistance film method, a capacitance method, a surface acoustic wave method, an infrared ray method, an electromagnetic induction method, an image recognition method, and an optical sensor method. good. Depending on the method, there are a method of detecting that there is a touch due to contact with the touch panel and a method of detecting that there is a touch due to the approach of a finger or a pen to the touch panel, but any method may be used.

As the touch panel, any of various touch panels such as a resistance film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method may be used. ..

FIG. 3 is a flow chart showing the basic flow from the start to the end of the digital camera.

After starting the camera, proceed to S301. In S301, it is determined whether or not the shooting mode is set based on the position of the mode changeover switch 60. If it is determined that the shooting mode is set, the process proceeds to S303, and if it is determined that the shooting mode is not set, the process proceeds to S302. In S302, it is determined whether or not the reproduction mode is set based on the position of the mode changeover switch 60. If it is determined that the mode is the reproduction mode, the process proceeds to S304, and if it is determined that the mode is not the reproduction mode, the process proceeds to S305. In S303, the shooting mode is processed. The shooting mode processing referred to here includes still image shooting, moving image shooting, and the like. In S304, the reproduction mode is processed. In the playback mode process, the still images and videos taken are mainly viewed, deleted, and edited. The details of the reproduction mode processing will be described later. In S305, other processing is performed. Other processing referred to here includes processing in the clock display mode that only displays the current time, processing for setting various menus, and the like. When each mode process is completed, the process proceeds to S306, and it is determined whether or not to shut down the camera operation. If it is determined to shut down, the camera operation is terminated, and if it is not shut down, the process proceeds to S301.

Next, the processing of the reproduction mode will be described in detail.

FIG. 5 is a flowchart of processing in the reproduction mode in the present embodiment. Each process in this flowchart is realized by the system control unit 50 reading a program stored in the non-volatile memory 56, expanding the program in the memory 32, and executing the program.

In S501, the system control unit 50 reads an image from the recording medium 200 and displays the read image on the entire display unit 28 as shown in FIGS. 4 (a), 4 (c), and 4 (e). And proceed to S502. A plurality of images taken in the shooting mode are recorded on the recording medium 200. In the shooting mode, a JPEG recording mode for recording a JPEG image, a RAW recording mode for recording a RAW image, and a RAW + JPEG recording mode for recording both a RAW image and a JPEG image can be selected. Recorded. In the JPEG recording mode, the captured image data is compressed into a JPEG format and recorded as a JPEG image file. In the RAW recording mode, the undeveloped RAW image data of the captured image is losslessly compressed and recorded as a RAW image file. In the RAW + JPEG recording mode, both a JPEG image file and a RAW image file are generated and recorded from the captured image. Since the RAW image data cannot be displayed without development processing, the RAW image file includes a JPEG image for display. Therefore, the RAW image file and the JPEG image file are recorded in the recording medium 200, and the RAW image file and the JPEG image file include those generated based on the same image. Since the RAW image file and the JPEG image file generated based on the same image are treated as one image, management information is recorded, and the display is performed based on one of the image files at the time of reproduction. It may be managed that the same image is shown by using common characters in the file name instead of the management information. Hereinafter, the image in which the RAW image file and the JPEG image file are recorded is referred to as a RAW + JPEG image, the image in which only the RAW image file is recorded is referred to as a RAW image, and the image in which only the JPEG image file is recorded is referred to as a JPEG image file.

4 (a) is a display example when a JPEG image is read from the recording medium 200, FIG. 4 (c) is a display example when a RAW image is read from the recording medium 200, and FIG. 4 (e) is recording. A display example when a RAW + JPEG image is read from the medium 200 is shown. In FIG. 4A, an image 400 based on a JPEG image and an icon 401 indicating that the image being displayed is a JPEG image are displayed on the display unit 28. Further, the display unit 28 also displays the number of images recorded in the recording medium 200 and the image number information display 402 indicating the number of the image currently being displayed. In the image number information display 402 of FIG. 4A, 100 images are recorded on the recording medium 200, and it is shown that the 50th image is currently displayed. In FIG. 4C, an image 430 based on a RAW image and an icon 431 indicating that the displayed image is a RAW image are displayed on the display unit 28. In FIG. 4 (e), an image 450 based on a RAW + JPEG image and an icon 451 indicating that the image being displayed is a RAW + JPEG image are displayed on the display unit 28. Further, also in FIGS. 4 (c) and 4 (e), the image number information displays 432 and 452 are displayed as in the image number information display 402 of FIG. 4 (a), respectively. By displaying any of the icon 401, the icon 431, and the icon 451 the user can grasp whether the currently displayed image is a JPEG image, a RAW image, or a RAW + JPEG image.

In S502, the system control unit 50 determines whether or not the erase button for receiving the erase instruction is pressed. If the erase button is pressed and the erase instruction is received, the process proceeds to the initial focus determination process of S503, and if the erase button is not pressed, the process proceeds to S506. When the initial focus selection process is completed, the process proceeds to the erase menu display process of S504, and the erase menu display process (S504) for displaying the erase menu based on the initial focus determined in S503 is executed. In this way, the erase menu is displayed together with the displayed image in response to the pressing of the erase button, but the item for displaying the initial focus in the displayed erase menu is determined by the initial focus determination process. After displaying the erase menu in the erase menu display process of S504, the process proceeds to the image erase process (S505) with the currently displayed image as the image to be erased. Details of the initial focus determination process (S503), the erase menu display process (S504), and the image erase process (S505) will be described later. When the image erasing process is completed, the process proceeds to S510.

In S506, the system control unit 50 determines whether the image feed button has been pressed. Specifically, it is determined whether or not the left button 143 and the right button 144 of the operation unit 70 are pressed. If the button assigned for image feed is pressed, the process proceeds to S507, and if the image feed button is not pressed, the process proceeds to S508.

In S507, the system control unit 50 performs image feed processing. When the left button 143 is pressed, the image before the currently displayed image is read, and when the right button 144 is pressed, the image next to the currently displayed image is read. Then, based on the read image, the display is performed in the same manner as in S501. For example, when the right button 144 is pressed in the state of FIG. 4A described above, the next image of the image 400 (the 51st image out of a total of 100 images) is displayed. Then proceed to S510. The image to be displayed can be switched by the image feed of S506 and S507, and the user can select the image to be processed by operating the left button 143 and the right button 144.

In S508, the system control unit 50 determines whether or not to perform other processing. Then, in S509, the system control unit 50 performs other processing according to the operation determined in S508. For example, when the menu button is pressed, various configurable menu screens are displayed on the display unit 28. The user can intuitively make various settings by using the menu screen displayed on the display unit 28 and the up / down / left / right four-direction buttons and the SET button. In the present embodiment, the user can set an item for displaying the initial focus when displaying the erase menu on the menu screen. The initial focus setting of the erase menu will be described in detail later. After executing other processing, the process proceeds to S510.

In S510, the system control unit 50 determines whether or not to end the reproduction mode. If it is determined that the reproduction mode is terminated, the reproduction mode is terminated, and if it is determined that the reproduction mode is not terminated, the process returns to S502 and the processes of S502 to S510 are repeated until the reproduction mode is terminated.

Next, the initial focus setting of the erase menu will be described.

FIG. 6 is a diagram showing an initial focus setting screen 600 that allows the user to set which item the initial focus should be displayed when the erase menu is displayed. The initial focus setting screen 600 is a part of the menu screen, and the initial focus setting is displayed on the display unit 28 according to the selection of the initial focus setting on the menu screen. On the initial focus setting screen 600, any one of 601 to 604 can be selected to set an item for displaying the initial focus in the erase menu.

Selecting "Cancel" 601 is a setting item for setting the display position of the initial focus to be the "Cancel" item for canceling the erasure of the image when the erase menu is displayed.

Select "Erase / RAW + JPEG Erase" 602 is a setting item for setting the display position of the initial focus to the item of "Erase" or "RAW + JPEG Erase" when the erase menu is displayed. When the image to be erased is a RAW + JPEG image, the item of "RAW + JPEG erase" for erasing both the RAW image file and the JPEG image file is initially focused. Then, when the image to be erased is not a RAW + PEG image, the item of "erase" is initially focused. That is, 602 is a setting item for initial focus display of an item for erasing an image file of all formats related to an image selected as an erasure target.

Selecting "RAW Erase" 603 is a setting item for setting the display position of the initial focus to be the item of "RAW Erase" for erasing only the RAW image file when the erase menu is displayed.

Reference numeral 604 is a setting item for setting the display position of the initial focus to be the item of "JPEG erasure" for erasing only the JPEG image when the erase menu is displayed.

Further, 620 indicates the focus on the initial focus setting screen 600, and is for indicating which item of 601 to 604 is selected. The system control unit 50 detects an operation on the upper button 141 and the lower button 142 by the user while displaying the initial focus setting screen 600, and sets the focus 620 to 601 in response to the operation on the upper button 141 and the lower button 142. Move to ~ 604. Further, when the system control unit 50 detects that the SET button 145 is pressed while the initial focus setting screen 600 is being displayed, the system control unit 50 selects the setting item from 601 to 604 in which the focus 620 is currently displayed at the initial stage of the erase menu. Confirm as the focus setting. Then, the information of the confirmed setting item is stored in the non-volatile memory 56 as the initial focus setting of the erase menu.

In this way, on the initial focus setting screen 600 in the menu screen, it is possible to set an item that is initially selected and the focus is displayed when the erase menu is displayed.

Next, the initial focus determination process (S503) and the erase menu display process (S504) will be described in detail, but first, the erase menu display process (S504) will be described first.

FIG. 8 is a flowchart showing the details of the erase menu display process. Each process in this flowchart is realized by the system control unit 50 expanding the program stored in the non-volatile memory 56 into the memory 32 and executing the program.

In S801, the system control unit 50 determines whether the image displayed on the display unit 28 is a RAW + JPEG image. If a RAW + JPEG image is displayed on the display unit 28, the process proceeds to S802, and if other images, that is, a JPEG image, a RAW image, a moving image, or the like is displayed, the process proceeds to S803.

In S802, the system control unit 50 displays the erase menu 460 as shown in FIG. 4 (f). FIG. 4 (f) shows a display example of the screen of the display unit 28 when the erase button is pressed while the display of FIG. 4 (e) is being performed. When the displayed image, that is, the image to be erased is a RAW + JPEG image, the erase menu 460 including four items (461 to 464) as shown in FIG. 4 (f) is displayed. The erase menu 460 includes "Cancel" 461 for canceling image erasure, "RAW + JPEG erasure" 462 for erasing both RAW image files and JPEG image files, and "RAW" for erasing only RAW image files. Four items of "Erase" 463 and "JPEG Erase" 464 for erasing only the JPEG image file are displayed.

In S803, the system control unit 50 displays the erase menu 410 as shown in FIGS. 4 (b) and 4 (d). FIG. 4B shows a display example of the screen of the display unit 28 when the erase button is pressed while displaying the JPEG image of FIG. 4A. Further, FIG. 4D shows a display example of the screen of the display unit 28 when the erase button is pressed while the RAW image of FIG. 4C is being displayed. If the displayed image, that is, the image to be erased is not a RAW + JPEG image, the erase menu 410 including two items (411, 412) as shown in FIGS. 4 (b) and 4 (d) is displayed. do. In the erase menu 410, two items, "Cancel" 411 for canceling the erasure of the image and "Erase" 412 for erasing the selected image, are displayed.

In S804, the system control unit 50 displays the focus 420 indicating the currently selected item in the displayed erase menu (410 or 460). Here, the focus 420 is displayed in the item determined by the initial focus determination process executed before the erase menu display process. In this way, when the erase button is pressed in the playback mode, the erase menu is displayed with the focus 420 displayed and the item initially selected as the initial focus in the initial focus determination process (S503). Is displayed.

For the sake of explanation, the processing of the erase menu display (S802, S803) and the initial focus display (S804) are separated, but the system control unit 50 performs these processes at the same time, and the erase menu and the initial focus are performed at the same time. It is displayed on the display unit 28.

Next, the initial focus determination process will be described in detail.

FIG. 7 shows the flow of the initial focus determination process in the present embodiment. Each process in this flowchart is realized by the system control unit 50 expanding the program stored in the non-volatile memory 56 into the memory 32 and executing the program.

In S701, the system control unit 50 determines whether or not the image displayed on the display unit 28 is a RAW + JPEG image. If it is a RAW + JPEG image, the process proceeds to S702, and if it is not a RAW + JPEG image, the process proceeds to S707.

In S702, the system control unit 50 reads the information of the initial focus setting of the erase menu set on the initial focus setting screen 600 from the non-volatile memory 56. Then, based on the read information, it is determined whether the initial focus setting set on the initial focus setting screen 600 is "cancel", "erase / RAW + JPEG erase", "RAW erase", or "JPEG erase". do. The system control unit 50 executes any of the processes S703 to S706 according to the initial focus setting set on the initial focus setting screen 600 determined in S702.

When the initial focus setting set on the initial focus setting screen 600 is "cancel", the system control unit 50 determines the item to be initially focused to be "cancel" 461 (S703). When the initial focus setting set on the initial focus setting screen 600 is "erase / RAW + PEG erase", the system control unit 50 determines the item to be initially focused to be "RAW + PEG erase" 462 (S704). When the initial focus setting set on the initial focus setting screen 600 is "RAW erase", the system control unit 50 determines the item to be initially focused to be "RAW erase" 463 (S705). When the initial focus setting set on the initial focus setting screen 600 is "JPEG erase", the system control unit 50 determines the item to be initially focused to be "JPEG erase" 464 (S706).

In this way, when the RAW + JPEG image is selected as the erasure target, the item set on the initial focus setting screen 600 is determined as the item on which the initial focus is displayed in the erasure menu 460. This is because the items (461 to 464) displayed in the erase menu 460 and the setting items (601 to 604) that can be set in the initial focus setting screen 600 have a one-to-one correspondence.

In S707, the system control unit 50 determines whether or not the image displayed on the display unit 28 is a JPEG image. If it is a JPEG image, the process proceeds to S708, and if it is not a JPEG image, the process proceeds to S713.

In S708, similarly to S702, the system control unit 50 determines the initial focus setting of the erase menu set on the initial focus setting screen 600, and performs the processes of S709 to S712 according to the determination result. In the case of a JPEG image, the number of items (411, 412) displayed in the erase menu 410 does not correspond one-to-one with the setting items (601 to 604) that can be set in the initial focus setting screen 600, so the image is erased. In the menu 410, the initial focus is determined as follows.

When the initial focus setting set on the initial focus setting screen 600 is "cancel", the system control unit 50 determines the item to be initially focused to be "cancel" 411 (S709). When the initial focus setting set on the initial focus setting screen 600 is "erase / RAW + PEG erase", the system control unit 50 determines the item to be initially focused to "erase" 412 (S710).

When the initial focus setting set on the initial focus setting screen 600 is "RAW erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S711). This is because even if "RAW erase" is set as the initial focus setting, the RAW image is not recorded because the erase target is a JPEG image, and the RAW image cannot be erased. Is determined to be "Cancel" 411.

When the initial focus setting set on the initial focus setting screen 600 is "JPEG erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S712). When the object to be erased is a JPEG image and "JPEG erase" is set as the initial focus setting, it is also possible to set the erase 412 as the initial focus in order to erase the JPEG image. However, when selecting the initial focus setting on the initial focus setting screen 600, it is premised on erasing the image in the RAW + JPEG image. Even if the JPEG image file is deleted in the RAW + JPEG image, the RAW image file is not deleted and the image file itself of the image to be deleted remains. On the other hand, if the JPEG image file is erased in the JPEG image, no image file corresponding to the image to be erased remains. When "JPEG Erase" is set in the initial focus setting on the assumption that at least one of the image files corresponding to the image to be erased remains, "Erase" 412 is initially focused in the case of a JPEG image. There is a possibility that the image will be erased by mistake. Therefore, when the JPEG image is selected as the erasure target, even if "JPEG erasure" is set as the initial focus setting, "Erase" 412 for erasing the JPEG image file is not initially focused, and "" Initial focus on "Cancel" 411.

In S713, the system control unit 50 determines whether or not the image displayed on the display unit 28 is a RAW image. If it is a RAW image, the process proceeds to S714, and if it is not a RAW image, the process proceeds to S719.

In S714, similarly to S702 and S708, the system control unit 50 determines the initial focus setting of the erase menu set on the initial focus setting screen 600.

When the initial focus setting set on the initial focus setting screen 600 is "cancel", the system control unit 50 determines the item to be initially focused to be "cancel" 411 (S715). When the initial focus setting set on the initial focus setting screen 600 is "erase / RAW + PEG erase", the system control unit 50 determines the item to be initially focused to "erase" 412 (S716).

When the initial focus setting set on the initial focus setting screen 600 is "RAW erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S717). In this way, when the target to be erased is a RAW image and "RAW erase" is set as the initial focus setting, it is also possible to set "Erase" 412 as the initial focus in order to erase the RAW image. be. However, when selecting the initial focus setting on the initial focus setting screen 600, it is premised on erasing the image in the RAW + JPEG image. Even if the RAW image file is deleted in the RAW + JPEG image, the JPEG image file is not deleted and the image file related to the image to be deleted remains. On the other hand, if the RAW image file is deleted in the RAW image, no image file corresponding to the image to be deleted remains. Therefore, when "RAW Erase" is initially focused on the assumption that at least one of the image files corresponding to the image to be erased remains, "Erase" 412 is initially focused in the case of the RAW image. There is a possibility that the image will be erased by mistake. Therefore, in the present embodiment, when the RAW image is selected as the deletion target, even if "RAW deletion" is set as the initial focus setting, the "erase" 412 for erasing the RAW image is initially focused. Instead, the "Cancel" 411 is initially focused.

When the initial focus setting set on the initial focus setting screen 600 is "JPEG erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S718). This is because even if "JPEG erase" is set as the initial focus setting, the JPEG image file is not recorded because the erase target is a RAW image, and the JPEG image cannot be erased, so the initial focus is set. The item is determined to be "Cancel" 411.

In S719, in this case, the image displayed on the display unit 28 is an image file in which an image of another format other than a RAW + JPEG image, a JPEG image, or a RAW image is recorded, for example, a moving image file or the like. Since there are many image compression formats and file formats other than RAW and JPEG, no further image format determination is performed. Then, in S714, similarly to S702, S708, and S714, the system control unit 50 determines the initial focus setting of the erase menu set on the initial focus setting screen 600, and processes S720 to S723 according to the determination result. conduct.

When the initial focus setting set on the initial focus setting screen 600 is "cancel", the system control unit 50 determines the item to be initially focused to be "cancel" 411 (720). When the initial focus setting set on the initial focus setting screen 600 is "erase / RAW + PEG erase", the system control unit 50 determines the item to be initially focused to "erase" 412 (S721).

When the initial focus setting set on the initial focus setting screen 600 is "RAW erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S722). Further, when the initial focus setting set on the initial focus setting screen 600 is "JPEG erase", the system control unit 50 determines the item to be initially focused to "Cancel" 411 (S723). When the image to be erased is neither a RAW + JPEG image, a JPEG image, or a RAW image, many compressed images and file format images can be considered. Therefore, only when "Erase / RAW + JPEG Erase" is selected, it is determined to be "Erase" 412, and in all other cases, it is determined to be "Cancel" 411.

The erase menu display process of FIG. 8 is executed based on the item of the initial focus determined by the initial focus determination process.

Next, the image erasing process (S505) after the erasing menu (410, 460) is displayed will be described in detail.

FIG. 9 is a flowchart showing the details of the image erasing process. Each process in this flowchart is realized by the system control unit 50 expanding the program stored in the non-volatile memory 56 into the memory 32 and executing the program.

With the erase menu (410, 460) displayed, in step S901, has the system control unit 50 operated the focus movement by operating the up button 141, the down button 142, the left button 143, and the right button 144? To judge. When there is a focus movement operation, in S902, the focus 420 of the erase menu (410, 460) being displayed is moved in the direction corresponding to the button operated in S901 and displayed.

Next, in S903, the system control unit 50 determines whether the SET button 145 has been operated and a determination operation for confirming the selection of the item in the erase menu has been performed. If it is determined that the determination operation has been performed, the process proceeds to S904, and if not, the process returns to S901 and the processes of S901 to S903 are repeated until the determination operation is performed.

In S904, the system control unit 50 determines whether the item selected (determined) in the erase menu is "erase" 412 or "RAW + JPEG erase" 462. When it is determined to be "erase" 412 or "RAW + PEG erase" 462, in S905, the system control unit 50 erases the image file corresponding to the currently displayed image from the recording medium 200. After that, the process proceeds to S910. That is, when the object to be erased is a RAW + JPEG image and "RAW + JPEG erase" 462 is selected, both the RAW image file and the JPEG image file are erased from the recording medium 200. If the object to be erased is an image that is not a RAW + JPEG image (RAW image, JPEG image, moving image, etc.), the image file of the currently displayed image is deleted. Then, if there is an image file of another format corresponding to the image file, the image file may be deleted as well, and the image file of all formats may be deleted.

In S906, the system control unit 50 determines whether the item selected (determined) in the erase menu is "RAW erase" 463. If it is determined that the "RAW erase" is 463, in S907, the system control unit 50 erases the RAW image file corresponding to the currently displayed RAW + JPEG image from the recording medium 200. In this case, only the RAW image file of the RAW + JPEG image is deleted, and the JPEG image file is left unerased. In addition, the management information indicating that the image is a RAW + JPEG image is also deleted, and the image is rewritten so that only the JPEG image file is treated as a recorded JPEG image. After that, the process proceeds to S911.

In S908, the system control unit 50 determines whether the item selected (determined) in the erase menu is "JPEG erase" 464. When it is determined that "JPEG erase" is 464, in S909, the system control unit 50 erases the JPEG image file corresponding to the currently displayed RAW + JPEG image from the recording medium 200. In this case, only the JPEG image file of the RAW + JPEG image is deleted, and the RAW image file is left unerased. In addition, the management information indicating that the image is a RAW + JPEG image is also deleted and rewritten so that only the RAW image file is treated as a recorded RAW image. After that, the process proceeds to S911.

If the item selected (determined) in the erase menu is neither "Erase" 412 or "RAW + JPEG Erase" 462, "RAW Erase" 463, or "JPEG Erase" 464, that is, "Cancel" 411 or "Cancel". In the case of 461, the process proceeds to S911 without erasing the image.

When the image file is deleted in S905, the system control unit 50 reads out the image next to the deleted image from the recording medium 200 in S910, displays the image of the read image on the display unit 28, and proceeds to S911. .. The processing of this display is the same as that of S501.

In S911, the system control unit 50 hides the displayed erase menu (410 or 460). Then, the image erasing process is terminated.

In the present embodiment, the RAW + JPEG image in which the RAW image and the JPEG image are simultaneously recorded has been described, but for example, the image may be an image in another compression format, recording format, or file format instead of the RAW image or JPEG image. .. Further, in the present embodiment, regarding the RAW + JPEG image, the RAW image and the JPEG image are recorded as different image files. However, for example, a RAW image and a JPEG image may be recorded in one image file by using a HEIF file or the like. In this case, if RAW + JPEG erase is selected, the entire image file is erased. Then, when RAW erase or JPEG erase is selected, only the corresponding image in the image file is erased.

As described above, according to the present invention, when erasing an image recorded in a plurality of formats (file format, compression format, recording format, etc.), an image in the desired format can be quickly set by setting the initial focus. Can be erased. Further, it is possible to prevent the image from being accidentally erased in the image recorded in a single format.
