The thumbnail image storage unit 106 acquires and stores the image 410 in the non-volatile memory 14. This is achieved by:

[0024] [View enlarged thumbnail image] Next, the user operation and display process when an enlarged thumbnail image is displayed are shown in Figure 2. Explained with reference to FIG. FIG. 4 is a flowchart showing an example of a processing procedure for displaying an enlarged thumbnail image. 5(A) to (C) are diagrams showing an example of a display of an operation screen. The state before the thumbnail image is specified, and the enlargement instruction image is shown in Fig. 5(B). In the displayed state, Fig. 5(C) shows the enlarged thumbnail image being displayed with the enlargement command image specified. This shows the state where

[0025] As shown in FIGS. 5(A) to 5(C), the display unit 40 in this embodiment has a position on the screen. The display shows a cursor 200 pointing to a character or image, and an operation screen 400. 0 is moved by the user's operation inputted via the input unit 20, and the screen designated by the user It is displayed to point to the above position, image, etc. The operation screen 400 includes thumbnail images 410a, 410b, and 410c, and buttons corresponding to various functions. A corresponding icon 420 and a toolbar 430 are displayed. The images 410a, 410b, and 410c may be collectively referred to as thumbnail image 410.

[0026] In the flowchart shown in FIG. 4, first, the operation determination unit 101 determines whether or not an operation has been performed via the input unit 20. Based on this, it is determined whether any of the thumbnail images 410 is specified (step In this embodiment, the operation determination unit 101 refers to the thumbnail image 410a. As shown in the figure, the operation of moving the cursor 200 is determined as a designation to the thumbnail image 410a. For example, when the cursor 200 is placed on the thumbnail image 410a, The operation is determined as a designation to the thumbnail image 410a. If the thumbnail image 410 is not specified (NO in step 501), The process waits until the image 410 is specified. As shown in FIG. 5B, the thumbnail image 410 If a is specified (YES in step 501), the instruction image output unit 103 enlarges The instruction image 412a is output and displayed (step 502).

[0027] Next, the operation determination unit 101 determines whether the enlargement instruction image 412 is an enlargement instruction image based on the operation via the input unit 20. It is determined whether a is specified (step 503). For example, the determining unit 101 may determine that the enlargement instruction image 412a is a mouse-over operation. As shown in FIG. 5B, the enlargement instruction image 412a is determined as the designated image. If not (NO in step 503), the enlargement instruction image 412a is not specified. As shown in FIG. 5C, when the enlargement instruction image 412a is specified, (YES in step 503 ), the enlarged image output unit 104 receives the image data from the thumbnail image storage unit 106 . The thumbnail image 410a is extracted from the thumbnail image 410a, and the enlarged thumbnail image 410a is obtained. The image 411a is output to the display unit 40 and displayed thereon (step 504).

[0028] Next, the operation determination unit 101 determines whether the designation of the enlargement instruction image 412a has been released. The enlargement instruction image 412a is released from the designated state (step 505). One of the problems is that the cursor moves from the enlargement instruction image 412a to the outside of the enlargement instruction image 412a. If the designation of the enlargement instruction image 412a has not been released (NO in step 505), The display of the enlarged thumbnail image 411a continues. The designation of the enlargement instruction image 412a is released. If the enlarged image is output to the display unit 40 (YES in step 505), the enlarged image output unit 104 The process stops and the enlarged thumbnail image 411a is hidden (step 506). Therefore, when the cursor 200 is on the enlargement instruction image 412a, the enlarged thumbnail image 41 1a is maintained. Also, the cursor 200 is moved to a position different from the enlargement instruction image 412a. , the enlarged thumbnail image 411a is hidden.

[0029] Next, the operation determining unit 101 checks whether the designation of the thumbnail image 411a has been cancelled. It is determined whether the thumbnail image 411a has been designated (step 507). If the answer is NO in step 507, the display of the enlargement instruction image 412a continues. When the designation to the cursor image 410a is released (YES in step 507), the instruction image is output. The output unit 104 stops outputting to the display unit 40, and the enlargement instruction image 412a is hidden. As a result, the operation screen 400 returns to the state before the thumbnail image 410a was selected (step Top 508). Through the above processing steps, the processing for displaying the enlarged thumbnail image 411a is completed.

[0030] In this embodiment, as described above, the thumbnail image 410a and the enlargement instruction image 412a A mouse over operation on the image is determined as a designation of the image. Then, the operation determination unit 101 detects other user operations, such as a click operation, on the thumbnail image 410. In addition to the thumbnail image 410a, the following may be determined: A specific key input operation or a command operation from the command section of the toolbar 430 may be set as a judgment condition. These conditions are all based on the user's operation to display the enlargement instruction image 412a. This is an example of a predetermined condition. Alternatively, without providing step 501, for example, the enlargement instruction image 412a may be constantly displayed. However, as in the present embodiment, the control based on the user's operation By configuring the device so that the enlargement instruction image 412a is displayed at the same time, the user can The display of the enlarged thumbnail image 411a is suppressed, improving the operability for the user.

[0031] Note that the enlargement instruction image 412a is arranged so as not to overlap with the corresponding thumbnail image 410a. In the case where the enlargement instruction image 412a is always displayed as described above, the thumbnail Even if the file image 410a and the enlargement instruction image 412a are displayed apart from each other, the enlargement instruction image 410a and the enlargement instruction image 412a are displayed separately from each other. Specifications can be made for 12a. However, as shown in FIG. 5B and FIG. 5C, the enlargement instruction image 412a is displayed as a thumbnail image 4 10a, the enlargement instruction image 412a and the thumbnail image 412b are displayed overlapping at least a part of the This makes it easier for the user to understand the correspondence between the image and the image 410a, and improves the operability of the user. In the form, from the designation of the thumbnail image 410a to the designation of the enlarged image 412a Operations can be performed smoothly.

[0032] Further, the enlarged thumbnail image 411a may be enlarged in a manner similar to the corresponding thumbnail image 410a or other thumbnail images. The nail image, the icon 420, the toolbar 430, etc. are displayed so as to overlap with other display contents. In this case, the enlarged thumbnail image may be arranged so as not to completely cover the enlargement instruction image 412a. By displaying the image 411a, unintentional cancellation of the designation to the enlargement instruction image 412a is suppressed. It can be controlled.

[0033] [Maintain display of enlarged thumbnail images] As described above, in this embodiment, when the designation of the enlargement instruction image 412a is released, the enlargement The large thumbnail image 411a is hidden. In this case, even if the enlargement instruction image 412a is released, the display of the enlarged thumbnail image 411a is maintained. It would be convenient to have a function that can be maintained. In the present embodiment, the image display device 1 is configured to display an image when a predetermined operation is performed by a user. In this case, even if the designation of the enlargement instruction image 412a is cancelled, the display of the enlarged thumbnail image 411a The state changes to one in which the

[0034] 6 and 7, the state in which the display of the enlarged thumbnail image 411a is maintained will be described. An example of a user's operation and a processing procedure will be described. FIG. 6 shows an example of a processing procedure for transitioning to a state in which the display of the enlarged thumbnail image 411a is maintained. 1 is a flowchart showing a process for 7(A) and (B) show a transition to a state in which the display of the enlarged thumbnail image 411a is maintained. 7A is a diagram showing an example of a display screen when the maintenance instruction image 413a is displayed. Display screen: FIG. 7B shows a display in a state where the display of the enlarged thumbnail image 411a is maintained. 1 shows an example of a screen.

[0035] In the flowchart shown in FIG. 6, first, the operation determination unit 101 (see FIG. 3) It is determined whether or not the image 412a (see FIG. 5(C)) is designated (step 601). If the enlargement instruction image 412a is not specified (NO in step 601), the enlargement instruction Wait for the image 412a to be designated and the enlarged thumbnail image 411a to be displayed. When 12a is specified and the enlarged thumbnail image 411a is displayed (step 60 1, YES), the instruction image output unit 103 outputs the maintenance instruction image 413a to the display unit 40 for display. In the present embodiment shown in FIG. 7A, the enlargement instruction image 412a In this case, the maintenance instruction image 413a is displayed as It also functions as an enlargement instruction image, and you can instruct enlargement by hovering the mouse over it. In other words, even if the enlargement instruction image 412a is changed to the maintenance instruction image 413a and displayed, The enlargement instruction image designated by the mouse cursor will not be released, and will remain as the enlargement instruction image. As long as the mouse over operation on 413a continues, the enlarged thumbnail image 411a The display is maintained.

[0036] Next, the operation determination unit 101 determines whether or not the maintenance instruction image 413a is specified. (Step 603). In this embodiment, the operation determination unit 101 determines whether the image is to be maintained (step 603). The click operation is determined as a designation to the maintenance instruction image 413a. The enlargement instruction image 412a and the maintenance instruction image 413a are designated by different user operations. By accepting the request via the "OK" button, the display of the enlarged thumbnail image 411a may be unintentionally maintained. This suppresses the transition to a non-reactive state. If the maintenance instruction image 413a is not specified (NO in step 603), the maintenance instruction If the maintenance instruction image 413a is specified, the maintenance instruction image 413a is waited for until the maintenance instruction image 413a is specified. If the answer is YES in step 603, the display of the enlarged thumbnail image 411a is maintained. Transition (step 604). As shown in FIG. 7B, in a state in which the display of the enlarged thumbnail image 411a is maintained, In the case where the mouse over operation on the maintenance instruction image 413a as the enlargement instruction image is canceled, Even if the enlarged thumbnail image 411a is changed, the display of the enlarged thumbnail image 411a is maintained. In the state where the display of 1a is maintained, other operations, such as a scroll operation on the operation screen 400, Even if the operation is performed, the display of the enlarged thumbnail image 411a is maintained. In this state, the position of the enlarged thumbnail image 411a on the screen is fixed, and the enlarged thumbnail image 411a is scrolled. Even if this is done, the enlarged thumbnail image 411a will not move.

[0037] Next, the operation determination unit 101 cancels the state in which the enlarged thumbnail image 411a is displayed. It is determined whether a division operation has been performed (step 605). In a position other than the area where the enlarged thumbnail image 411a is displayed, for example, in FIG.
