[0022]
The arrangement of these operation buttons can be changed by a drag-and-drop operation. Also, buttons that cannot be operated depending on the situation may be displayed in halftone.
As shown in FIG. 4 (b), when the scroll button 40 is touched (Step 1), the display image generation unit 26 scrolls the display of the display screen. Here, moving images A to P are recorded on the magneto-optical recording medium 22, and the display image creating unit 26 displays thumbnails corresponding to these moving images as thumbnails A to P.
[0023]
Note that all operations performed by the operator are performed via the touch panel 28, which utilizes a well-known technique such as a GUI (Graphical User Interface).
In other words, thumbnails and operation buttons are displayed as objects on the liquid crystal display unit 27, and the touch panel 28 and the touch panel input unit 29 sense a touch operation of the operator on these objects.
[0024]
The control unit 30 generates a message unique to the object on the screen in response to the contact operation. Further, the display image creating unit 26 acquires the message and changes the screen display. Hereinafter, description of this portion will be omitted.
When the thumbnail is touched, the microprocessor 31 recognizes that the thumbnail and the moving image corresponding to the thumbnail have been selected, and highlights the thumbnail.
[0025]
Further, the selected moving image is accompanied by a scenario file indicating how to reproduce the moving image (for example, slow reproduction, fast forward reproduction, fade-in fade-out reproduction, display area size, etc.) in a data format. Have been. This scenario file is added to the header portion of each moving image file and the like, and is recorded on the magneto-optical recording medium 22. This scenario file corresponds to the identification information described in claim 3 and the playback state described in claim 4.
[0026]
Here, as shown in FIG. 4 (b), thumbnail F is selected (operation 2), F1 is displayed as a scenario file.
When the highlighted thumbnail is further touched, the microprocessor 31 detects the operation and displays a list of scenario files of moving images . The microprocessor 31 determines whether a touch operation has been performed on the scenario file list display area and the thumbnail, and recognizes which scenario file the operator has selected.
[0027]
For example, as shown in (c) of FIG. 5, the thumbnail F is touched (step 3), the microprocessor 31 displays a list from F1 as a scenario file to F4.
When a touch operation is performed in the scenario file list display area (operation 4), the microprocessor 31 moves the * mark sequentially down and displays it. When the touch operation is repeated, the * mark is displayed once.
[0028]
When the thumbnail F is touched again while the * mark is displayed beside F3 (operation 5), the microprocessor 31 recognizes that F3 has been determined as the scenario file.
Further, when a touch operation is performed on the selection button 54, the microprocessor 31 recognizes that the confirmed scenario file has been selected, and displays the selected scenario file in the selected scenario display field 52.
[0029]
As shown in (d) of FIG. 5, when the selection button 54 is touched (step 6), the microprocessor 31 displays the scenario file F3 of the moving image F to the selected scenario display field 52. Note that even when the operation 5 is omitted and the operation 6 is performed, the microprocessor 31 recognizes that the scenario file has been selected.

(F) in FIG. 6 is a diagram showing that it has been selected as well P4, D1 scenario file.
[0031]
In this state, when the erase button 55 is touched, the microprocessor 31 cancels the selection of (D1 in this case) scenario file * mark in the selection scenario display column 52 is displayed next, in FIG. 7 As shown in (g), the scenario file is deleted from the selected scenario display field 52.
As another erase method, as shown at (h) in FIG. 7, the operator drag and drop operation a scenario file D1, is moved to the outside of the selected scenario display field 52, the microprocessor 31 The scenario file is deleted from the selected scenario display field 52.
[0032]
FIG. 8 (i) is a diagram showing that the scenario file D2 is newly selected by the operation of selecting the scenario file.
In a state where the scenario file is more selected, the simultaneous mode button 53 is touched (step S2 in FIG. 2, step S3), as shown in (j) of FIG. 8, the microprocessor 31 selects the scenario display field Only the thumbnails corresponding to the 52 scenario files are selectively displayed (step S4 in FIG. 2 ).
[0033]
Next, when the play button 47 is touched (step S5 in FIG. 2 ), as shown in FIG. 9 (k), the microprocessor 31 determines the size of the thumbnail display area and the moving image corresponding to each thumbnail. The reproduction is started at the same timing. Each moving image is reproduced in parallel according to the scenario file (step S6 in FIG. 2 ), and the reproduction is sequentially ended in ascending order of reproduction time.
[0034]
The operation of the same timing parallel reproduction will be described with reference to a flowchart (FIG. 3 ).
The moving image F recorded on the magneto-optical recording medium 22 is sought (step S1 in FIG. 3 ), and the moving image F is read therefrom (step S2 in FIG. 3 ). The image data is expanded by the data compression / expansion unit 24 and stored in the frame memory 25 (step S3 in FIG. 3 ).
Next, the image data of the moving image H, the moving image P, and the moving image D are sequentially read and stored in the frame memory 25 (steps S4, S5, and S6 in FIG. 3 ). The display image creation unit 26 creates image data based on each scenario file, and combines and displays each image data at a predetermined position (Step S7 in FIG. 3 ).
[0035]
For example, if the scenario file F3 is a fast-forward reproduction, image data with frames dropped is created.
The above operation is repeated until the stop button 46 is pressed (step S8 in FIG. 3 ).
As described above, the moving images are read out in a time-division manner, the images are created, and the images are combined and displayed, thereby performing the same-time parallel reproduction.

Here, information such as a file name of a moving image reproduced in parallel at the same timing, a scenario file attached to the moving image, a reproduction display position and a reproduction display area of each moving image are recorded.
More specifically, the microprocessor 31 is instructed so that the moving images F, H, P, and D are reproduced in parallel in the thumbnail display area at the same timing according to the scenario files F1, H1, P4, and D2. Create a scenario file Q1.
[0038]
This scenario file Q1 is stored in the magneto-optical recording medium 22 via the data access unit 23.
The microprocessor 31, as shown in Figure 1 0 (m), additionally displays the last thumbnail Q of the thumbnail display screen. At this time, the same image as the thumbnail F is used as the image used for the thumbnail Q.
[0039]
Thereafter, when the scenario file Q1 is selected and the play button 47 is pressed, the microprocessor 31 reads the scenario file Q1 from the magneto-optical recording medium 22, and reproduces a playback state according to the scenario file. Here, the state of (k) in FIG. 9 is reproduced, and parallel reproduction is performed at the same timing.
Next, the rearrangement of thumbnails will be described.
[0040]
In FIG. 8 (j), when the operator wants to rearrange the thumbnails selected and displayed, the operator moves the thumbnails to the position where the thumbnails are to be inserted by dragging and dropping, and all the thumbnails are rearranged and displayed. .
Here, as shown in (n) in FIG. 1 0, put a thumbnail F thumbnail H, between the thumbnail P, as shown in (o) in FIG. 1 1, sort the thumbnails.
[0041]
At this time, the microprocessor 31 selects a thumbnail (here, thumbnail F) corresponding to the touched position, moves and displays the thumbnail F in accordance with the drag operation of the operator, and moves the thumbnail F to the dropped position (thumbnail H and H). The thumbnail F is inserted between the thumbnails P), and the thumbnails are rearranged and displayed.
[0042]
Further, in the operation shown in FIG. 1 1 (p), may be replaced thumbnails. When the thumbnails H and F are quickly touched twice (corresponding to a double click of the mouse) (operations 7 and 8), the microprocessor 31 replaces the two thumbnails H and F with each other. Recognize the selection.
Next, the microprocessor 31 replaced the display position of two of the selected thumbnail is displayed as shown in (q) of FIG 2.
[0043]
