Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a still image display device which takes out still image data from a filing device such as a magneto-optical disk device and supplies it to a display to display a still image on the display.

[0002]

2. Description of the Related Art Conventionally, as a method of dividing an image on a display screen 100 to display an image, there is a method in which the number of divided images is predetermined. In the example of FIG. 9A, the screen 100 is evenly divided into 16 parts, and a maximum of 16 images are displayed simultaneously. In the figure, three images P1 to P3 are displayed.

Further, as a method of displaying an image by dividing the screen 100 of the display, there is a method of displaying a plurality of images in arbitrary sizes. In the example of FIG. 9B, the screen 100
Three images of P1 to P3 are displayed in.

[0004]

In the former method, even if the number of images displayed simultaneously is three,
There is a problem that each image can be displayed only in a size of 1/16 of the screen 100. Further, in the latter method, it is necessary to adjust the size and position of the screen each time the number of images to be displayed increases, which causes a problem of extra labor for the operator.

Therefore, the present invention provides a still image display device capable of automatically displaying images in an appropriate screen size according to the number of images to be displayed simultaneously.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a filing device storing still image data, a display for displaying a still image, and a filing device interposed between the filing device and the display are provided. And a control unit for displaying a still image by supplying the image to a display and providing a division mode setting means. In this division mode, the number of divisions of the screen of the display is automatically changed according to the number of display images. It is a feature.

[0007]

In the above structure, when the number of images to be displayed simultaneously is small, the number of divisions of the screen 100 is automatically reduced so that each still image is displayed large on the screen 100. On the contrary, when the number of images to be displayed simultaneously is large, the number of divisions of the screen 100 is automatically increased and each still image is displayed small on the screen 100. That is, a still image is automatically displayed in an appropriate screen size (for example, the maximum size determined by the number of still images) according to the number of images to be displayed simultaneously.

When the next still image P (10) is displayed while the still image P (9) is being displayed, the mode C is selected and the portion "1" to "9" (1/9) is displayed. Still images P (2) to P (10) are displayed as reduced images on the divided screen (shown in FIG. 6C). When the next still image P (11) is displayed in this state, the mode C is selected and the part (1) to (9) (1 /
Still images P (3) to P (11) are displayed as reduced images on the divided screen 9 (shown in FIG. D). Below, a new still image P (1
When 2), P (13), ... Are displayed, old still images are sequentially deleted, and the state in which nine still images are displayed on the screen 100 is maintained.

FIG. 6 is a flowchart showing the search operation of the system main body 11 in the split screen mode described above.

First, N = 1 and K = 1 are set (step 101). Next, it is determined whether or not a still image is designated (input of a unique number) by operating the keyboard 14 or the like (step 102). When the still image is not designated, it is determined whether or not the ending operation is performed with the keyboard 14 or the like (step 103). Step 1 if the end operation has not been performed
Return to 02.

When a still image is designated in step 102, N and a unique number are written in the RAM 11c (step 104).

Next, it is judged whether N = 1, N = 2 to 4, or N> 4 (step 10).
5). If N = 1, after the mode A is selected (step 106), the still image P designated by the unique number is selected.
(1) is displayed on the entire screen of the display 12 (step 107). Then, N = N + 1 is set (step 108), and the process returns to step 102.

When N = 2 to 4 in step 105, after mode B is selected (step 109),
The Nth still images P (1) to P (N) are displayed on the display 1
It is displayed on the split screen of "1" to "N" (1/4 split screen) 2 (step 110). Then, N = N + 1 is set (step 111), and the process returns to step 102.

When N> 4 in step 105, after mode C is selected (step 112), it is determined whether N> 9 (step 113). When N> 9 is not satisfied, the still images P (1) to P (N) of Nos. 1 to N are displayed on the display 12 "1" to "N" split screens (1/9 split screen). (Step 114). And
N = N + 1 is set (step 115), and step 10
Return to 2.

When N> 9, the still images P (N-8) to P (N) of (N-8) to N are displayed as "N-8-K" to "N-". It is displayed on a split screen of "K"("1" to "9") (step 116). And N = N
+1 and K = K + 1 are set (step 117), and the process returns to step 102.

When the end operation is performed in step 103, the RAM 11c is cleared (step 118),
The search operation ends.

As described above, in this example, in the split screen mode, the number of divisions of the screen 100 of the display 12 automatically changes according to the number of still images to be displayed, so that each still image can be displayed in an appropriate screen size (still It can be displayed in the maximum size determined by the number of strokes. In this case, since the system automatically selects the number of divisions, the operator does not have to bother with an unnecessary operation.

It should be noted that, instead of the above, it is possible to select some of the plurality of still images displayed on the split screen by operating the keyboard 14 or the like and display only these still images again. For example, if C mode is selected, "1"
~ Still image P (3) in the "9" part (1/9 split screen) ~
With P (11) displayed (shown in FIG. 7A), four still images P (3), P (5), P (7), P (11) (shown with diagonal lines in FIG. 7A) are displayed. When selected, B mode is selected,
A still image P is displayed in the portion of "1" to "4" (1/4 split screen).
(3), P (5), P (7), P (11) are displayed (shown in FIG. 9B).

In the above embodiment, the number of divisions of the screen 100 is increased in three steps in response to the increase in the number of still images to be displayed. If the number of images is determined, the number of divisions corresponding to the number of still images may be directly set by operating the keyboard 14 or the like.

In the above embodiment, the screen 100 is displayed.
Is a maximum of 9 divisions, but is not limited to this, and may be 16 divisions, 25 divisions ,. However, the larger the number of divisions, the more difficult the image recognition becomes. The difficulty of this recognition is that NTSC, H
The maximum number of divisions is determined according to the system because it depends on the type of video signal such as D (high quality) and computer image.

The screen 100 need not be divided into 9, 16, 25, etc., but if each divided screen maintains the aspect ratio (for example, 4: 3),
An empty area appears on the screen 100. Image information or the like may be displayed in this empty area as shown in FIG. 8A, or may be a frame of each divided screen as shown in FIG. 8B.

Further, each divided screen may be displayed without maintaining the aspect ratio as shown in FIG. Further, as shown in FIG. 4D, the divided screens are not made the same size, and the screen 100 is displayed without creating an empty area.
May be used as a whole.

Further, in the above embodiment, the example in which the filing device is the MO drive has been shown, but it may be another optical disk device, magnetic disk device or the like.

[0040]

According to the present invention, in the split screen mode, the number of split screens of the display automatically changes according to the number of still images to be displayed, so that each still image is always displayed in an appropriate screen size. Can be displayed. Further, since the number of divisions is automatically selected, the operator does not have to bother with an unnecessary operation.
