Description

The present invention particularly relates to a display control device, a control method for the display control device, a program, and a storage medium suitable for use when selecting a plurality of objects to be processed.

Conventionally, there has been known a method in which a user selects an image by designating a range on a screen on which a plurality of images are displayed, and executes processing on the selected image. However, depending on the content of the process to be executed, there is often an upper limit on the number of images that can be executed at one time, and the user must select an image in consideration of the number of selectable images.

Generally, when the number of selectable sheets is exceeded, the user is notified of a message indicating that the number of selectable sheets has exceeded the upper limit, a message indicating the number of selectable sheets, and the like. Patent Document 1 discloses a method of not increasing the range designation frame any more when the upper limit of the selectable capacity is reached during the designation of the selection range. In this method, for example, a certain range is cut out from an image on a screen recorded on a recording medium and selected, and when recording on another recording medium having a small capacity, selection of a range exceeding the recordable capacity is restricted. I'm trying to do it. Further, Patent Document 2 discloses a method of scrolling a displayed object in the opposite direction when an operation of scrolling from the upper limit of the display range to the other side of the upper limit is accepted.

In this way, when the number of objects to be processed reaches the upper limit, the user is notified of a message or the user's operation is restricted to encourage the user to recognize the upper limit and suppress meaningless operations. It is said that it can be done.

Japanese Unexamined Patent Publication No. 2000-56882 Japanese Patent No. 5871937

However, when selecting an image by specifying a range on the screen, even if the notification that the number of selected images exceeded the upper limit was confirmed, it was not possible to select the image that could be selected and how far the upper limit of the number of selected images was. It is difficult to know where the boundary with the image is. If it is difficult to see the boundary between the selected image and the unselected image, it is difficult to know where the next image you want to select was when you want to execute the processing for the maximum number of selected images and continue the processing. As a result, it takes a lot of time and effort to operate.

In view of the above-mentioned problems, it is an object of the present invention to make it easier for the user to recognize the items at the end of the selectable range when the number of selected sheets reaches the upper limit.

The display control device according to the present invention includes a display control means for displaying a list of a plurality of objects on the display means, and an operation means for accepting a designated operation for designating a selection range from the plurality of objects displayed in the list. However, when the number of objects included in the selection range specified by the designated operation exceeds the upper limit, the display control means controls to highlight the objects at the end of the range up to the upper limit. And.

According to the present invention, when the number of selected items reaches the upper limit, the user can easily recognize the items at the end of the selectable range.

FIG. 2 is a diagram showing an example of an external configuration of the image display device 100 according to the present embodiment.
In FIG. 2, the liquid crystal display panel 230 is a panel for displaying images and various information, and corresponds to the display 105 of FIG. Further, as shown in FIG. 2, the operation unit 106 has a plurality of operation members. Hereinafter, the functions of these operating members will be described.

The play button 212 is an operating member mainly used for displaying an image on the display 105. The set button 213 is mainly used to determine the image to be selected. The main dial 214 is usually used to feed one image, and on a screen displaying a plurality of images, it is used to feed one page of images. The sub dial 215 is mainly used for feeding one image.

The cross-shaped button 220 is composed of an upper button 222, a lower button 223, a left button 226, and a right button 227. The up / down button 221 composed of the up button 222 and the down button 223 is mainly used to move the focus in the up / down direction. Further, the left / right button 225 composed of the left button 226 and the right button 227 is mainly used for moving the focus in the left / right direction.

The menu button 240 is mainly used to display the menu screen on the display 105. The image display device 100 according to the present embodiment has a function (protection) of protecting the image from being accidentally erased by the erasing function of the camera. The protection range designation button 260 is mainly used when designating a range for selecting an image and transitioning to a screen for setting protection for the selected image.

Next, a specific procedure of the process of designating the selection range when a plurality of images are displayed will be described with reference to the flowcharts of FIGS. 3 and 5. These flowcharts are realized by reading the program recorded in the non-volatile memory 103 into the memory 102 and executing the program by the CPU 101. Hereinafter, a procedure for designating an image protection range on the screen and performing protection processing will be described with reference to the flowchart of FIG. 3 and the screen display example of FIG.

FIG. 3 is a flowchart showing an example of a processing procedure for designating a protection range in the present embodiment.
First, when the protection range designation button 260 is received in the playback screen transitioned by the playback button 212, the process shown in FIG. 3 is started. Then, in S301, the CPU 101 displays a list of a plurality of images (thumbnail images) on the screen of the display 105.

FIG. 4A shows an example of the screens listed by S301. In FIG. 4A, 36 images from the image “A” 401 to the image “AJ” 403 and the selected number display 402 are displayed on the screen. In the example shown in FIG. 4A, the focus is on the image “M” 404, and the image “M” 404 is displayed in a larger size than the other images. Further, the selected number display 402 displays the number of images selected by designating a range, but is displayed as "0" because there is no selected image at the stage of S301.

Next, in S302, the CPU 101 determines whether or not the operation of the set button 213 or the tap operation on the focused image is accepted. If any of these operations is accepted, the process proceeds to S303, otherwise the process proceeds to S308. The SET touch button may be displayed on a screen (not shown), and when the SET touch button is tapped in S302, it may be considered that the set button 213 has been accepted. In S303, the CPU 101 determines whether or not the start point image has already been set. If the start point image has not been set yet, the process proceeds to S304, and if the start point image has already been set, the process proceeds to S305.

In S304, the CPU 101 sets the image currently in focus as the start point image. When the start point image is set, the CPU 101 displays the focus frame of the image “M” 405 thicker than before the start of the range designation, as shown in FIG. 4B, in order to indicate that the range designation has started. The display is performed on an image existing in the range from the start point image to the image currently in focus. As for the expression of the display, it is sufficient to specify the range and know that the image is selected. Therefore, the color of the focus frame or the color of the image can be changed with respect to the selected image. , An icon may be displayed on the image. In the selected number display 402 shown in FIG. 4B, since only one image is selected, "1" is displayed.

Further, FIG. 4C shows a state in which the focus is moved from the state of FIG. 4B and the range from the image “M” 406 to the image “P” 407 is specified. The selected number display 402 in FIG. 4C is displayed as “4” because four images from the image “M” 406 to the image “P” 407 are selected. The focus movement process will be described later.

As a result of the determination in S303, if the start point image has already been set, in S305, the CPU 101 sets the image currently in focus as the end point image. Then, in S306, the CPU 101 executes the protection process for the images in the range from the start point image to the end point image. Then, in S307, the CPU 101 cancels the setting of the start point image and the end point image.

FIG. 4D shows a state after the protection processing is executed for the images from the image “M” 408 to the image “P” 409. The icon 410 is displayed on the image on which the protection process has been executed. The selected number display 402 in FIG. 4D is displayed as “0” because the range designation has been completed by canceling the setting of the start point image and the end point image.

On the other hand, in S308, the CPU 101 determines whether or not there has been a focus movement operation. That is, the CPU 101 determines whether or not the cross-shaped button 220, the sub-dial 215, or the like is operated to receive an instruction to move the focus. If there is a focus movement operation, the process proceeds to S309, and if not, the process proceeds to S310.

In S309, the CPU 101 performs a selection determination process. The details of the selection determination process will be described later.
On the other hand, in S310, the CPU 101 determines whether or not the menu button 240 or the protect range designation button 260 has been operated. If the menu button 240 or the protection range specification button 260 is operated, the protection range specification process is terminated, and if not, the process returns to S302.

Next, the details of the selection determination process of S309 will be described with reference to the flowchart of FIG. 5 and the screen display examples of FIGS. 6 and 7.
FIG. 5 is a flowchart showing an example of a detailed processing procedure of the selection determination processing of S309.
First, in S501, the CPU 101 calculates the amount of focus movement according to the operation. The relationship between the operation and the amount of focus movement will be described later with reference to FIG.

In S502, the CPU 101 determines whether or not the start point image has already been set. If the start point image has already been set, the process proceeds to S503, and if the start point image has not yet been set, the process proceeds to S508.

In S503, the CPU 101 calculates the number of selected sheets when the range including the movement amount of the focus calculated in S501 is specified. Then, in S504, the CPU 101 determines whether or not the selected number of sheets calculated in S503 exceeds the preset upper limit of the selected number of sheets. The upper limit of the number of selected sheets differs depending on the process to be executed and the conditions, and in the protection process of the present embodiment, the upper limit of the number of selected sheets is 999. If the upper limit of the number of selected sheets is exceeded, the process proceeds to S505. If not, the process proceeds to S508.

In S508, the CPU 101 moves the focus on the screen by the amount of focus movement calculated in S501. FIG. 6A shows a state in which the current focus is on the image “U” 606 when the image “A” 604 is set as the start point image. In the selected number display 602 of FIG. 6A, since the range from the image “A” 604 to the image “U” 606 is specified, it is displayed as “21”. When the start point image is set, the focus frame is enlarged and displayed with the image between the image "A" 604 and the image "U" 606 to indicate that the image is selected as the range specification. I am doing it.

Here, the operation of moving the focus will be described.
When the focus movement operation is the operation of the left / right button 225 or the sub dial 215, the CPU 101 moves the focus by one to the left or right. FIG. 6B shows a state in which the right button 227 is operated or the sub dial 215 is rotated clockwise from the state of FIG. 6A, and the focus is moved by one to the right. In this case, since the images up to the image "V" 608 are selected, the display of the selected number display 602 is updated to "22".

When the focus movement operation is the operation of the up / down button 221, the focus is moved one up or down. FIG. 6 (c) shows a state in which the lower button 223 is operated to move the focus downward by one from the state of FIG. 6 (a). In this case, since the images up to the image "AA" 610 are selected, the display of the selected number display 602 is updated to "27". In the example shown in FIG. 6, since 6 images are displayed in one line, the number of selected images increases by 6 when the focus moves downward, but when 10 images are displayed in one line, The number of selected sheets will be increased by 10.

If the focus movement operation is a tap operation on the image, the focus is moved to the tapped image. FIG. 6D shows a state in which the image “K” 612 is tapped in the state of FIG. 6A and the focus is moved to the image “K” 612. In this case, since the images up to the image "K" 612 are selected, the display of the selected number display 602 is updated to "11".

When the focus movement operation is the operation of the main dial 214 or the touch move, the image for one page of the screen is sent, and the focus is moved to the image at the same position as the place where the focus was before the operation. In FIG. 6 (e), an image for one page of the screen is sent by rotating the main dial 214 clockwise or by touch-moving upward from the state of FIG. 6 (a), from the image "AK" 614 to the image "BT" 616. It shows the state where 36 images of are displayed. In this case, the focus position has moved to the position of the image "BE" 612, and the display of the selected number display 602 specifies a range from the image "A" 604 which is the start point image to the image "BE" 612. Therefore, "57" is displayed.

On the other hand, in S505, the CPU 101 calculates the difference between the selected number of sheets calculated in S503 and the preset upper limit, and calculates the difference from the focus position when the focus is moved by the focus movement amount calculated in S501. Identify the subtracted position. That is, the focus position when the number of selected sheets is the upper limit is specified.

Next, in S506, the focus frame is enlarged and displayed for the images up to the position specified in S505. Then, in S507, the CPU 101 highlights the image at the end of the range (the image at the position specified in S505).

FIG. 7A shows a state in which an image outside the screen is set as a start point image and the current focus position is the image “U” 704. In the selected number display 702 of FIG. 7A, a range from the start point image outside the screen to the image “U” 704 is specified, and since 999 images are selected, “999” is displayed. In this state, the number of selected sheets has reached the upper limit of 999.

In the state of FIG. 7A, if there is a focus movement operation for increasing the number of selected sheets, the number of selected sheets exceeds the upper limit. Therefore, in S507, animation display is performed in which the display states of FIGS. 7 (b) and 7 (c) are alternately switched at predetermined time (for example, about 0.5 seconds). In FIG. 7B, the image “U” 706 is not displayed in a large size, but is displayed in a thick frame in the same size as the other images in the selection range. In FIG. 7C, the image “U” 708 is displayed in a larger size than the other images, emphasizing that it is at the edge of the range. That is, an animation display is performed in which the size of the image "U" 708 changes alternately in size (alternate display of reduction and enlargement). In this way, the image at the edge of the range can be highlighted so that it can be distinguished from other selected images, making it easier for the user to recognize the image at the edge of the selected range. If the number of selected images has not reached the upper limit, the image at the end of the selected range is displayed in a large size, but no animation is displayed. Therefore, the user can recognize that the upper limit has been reached (it has changed from the state where the upper limit has not been reached) by seeing the image at the end of the selected range being animated. The animation display for alternately switching between FIGS. 7 (b) and 7 (c) is started in response to a focus movement operation exceeding the upper limit, and is stopped when the switching is performed one or more predetermined times. For example, when the predetermined number of times is one, when the lower button 223 or the right button 227 is pressed in the state of FIG. 7A, the number of selected images is not increased (without increasing the number of images whose frame is bold). , FIG. 7 (b) is displayed, and after 0.5 seconds, FIG. 7 (c) is displayed. Then, the display state of FIG. 7C is maintained. When the predetermined number of times is three, if the lower button 223 or the right button 227 is pressed in the state of FIG. 7A, FIG. 7B is performed every 0.5 seconds without increasing the number of selected sheets. , FIG. 7 (c), FIG. 7 (b), FIG. 7 (c), FIG. 7 (b), and FIG. 7 (c). Then, the display state of FIG. 7C is maintained. In this way, the display does not change at all for the user operation that attempts to make a selection exceeding the upper limit, and highlighting (animation display) is performed according to the operation. Therefore, when the user presses the lower button 223 or the right button 227 but the number of selected sheets does not increase, the operation is not ignored and the user cannot increase the number for some reason (the upper limit has been reached and cannot be increased). It can be recognized that it is a state). In the present embodiment, the image is highlighted by an animation that changes the size of the image at the end of the range, but the color in the image is changed, the image is blinked, or the image is displayed at the end of the range. You may want to highlight it by changing the color of the frame around it. In any case, the highlighting starts in response to an operation that attempts to exceed the upper limit and ends after a predetermined time.

As described above, according to the present embodiment, when the number of selected images reaches the upper limit while the range is specified, the image at the end of the selected range is highlighted so as to be distinguishable from other images. I tried to do it. This makes it easier to recognize the image at the edge of the range selected by the user, and the next time the range is specified for the image to be selected, the image can be easily selected.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described. Since the configuration and processing of the image display device according to the present embodiment are basically the same as those of the first embodiment, the description thereof will be omitted. Hereinafter, only the parts different from the first embodiment will be described.

In the present embodiment, when the number of selected sheets exceeds the upper limit as a result of moving the focus, in S506, the CPU 101 moves the focus once with the movement amount of the focus calculated in S501, and then focuses on the image at the end of the range. To move.

FIG. 8A shows a state in which the image outside the screen is set as the start point image and the current focus is the image “S” 804. In the selected number display 802 of FIG. 8A, a range from the start point image outside the screen to the image “S” 804 is specified, and 997 images are selected, so that “997” is displayed. FIG. 8B shows a state in which the lower button 223 is operated in the state shown in FIG. 8A and the focus is once moved to the image “Y” 806. Here, since the upper limit of the number of selected images is exceeded in the range up to the image "Y" 806, the focus is subsequently moved to the image "U" 808 which is the upper limit of the number of selected images as shown in FIG. 8C. In S506 of the first embodiment, the state of FIG. 8 (a) is directly transferred to the state of FIG. 8 (c), but in S506 of the present embodiment, the state of FIG. 8 (b) is passed through. It shifts to the state of (c).

After that, in S507, the image "U" 808 in focus as shown in FIG. 8D is displayed in a size larger than that of the other images and highlighted. In the selected number display 802 of FIG. 8C, the range from the start point image outside the screen to the image "U" 808 is specified, and the upper limit of the selected number is selected, so that "999" is displayed. To.

As described above, according to the present embodiment, when the number of selected sheets reaches the upper limit while the range is specified, after focusing on the image at the end of the range specified by the user, the upper limit range is set. Changed to highlight the edge image. This makes it easier for the user to recognize that the range selected by the user exceeds the upper limit. In addition, the image can be easily selected when the range is specified for the image to be selected next.
