Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display method for displaying moving image data consisting of continuous images as individual images on a display device.

An important image and a less important image may coexist in a series of moving images, and it is convenient if a viewer can easily identify them without wasting time. .

[0003]

2. Description of the Related Art Conventionally, all individual images constituting moving image data are treated and displayed in the same manner. Also, there is a search for a change point in the moving image data, but it retrieves only the change point, and there is no search for the intermediate moving image data reaching the change point.

[0004]

When displaying moving image data, conventionally, the size, resolution, or display timing of each image forming the moving image data remains constant, and even if it is an important image. , Fast-forwarding and slow display were performed constantly, and the display method was not changed depending on the importance of those images. Therefore, there is a drawback that the importance of the image cannot be confirmed until the displayed contents of the displayed image are viewed.

[0005]

[Means for Solving the Problems] Normally, when displaying moving image data, continuous individual images are displayed. Here, by assigning importance to each of these individual images or to some of the individual images, important images and unimportant images are distinguished, and images in the middle also have individual importance. Interpolate from. Moreover, the display shape or the display form is changed according to the importance.

[0006]

According to the importance of the moving image data to be displayed, the size of the image is changed as the display shape and the display is changed such as resolution or fast forward display / slow display.

[0007] When switching from an unimportant scene to an important scene, or vice versa, by confirming the scene switching according to the importance by changing the color or the lightness, or vice versa, it is possible to confirm without looking at the displayed contents. Will be possible.

Further, by changing the image reproduction speed or the like according to the importance, it is possible to efficiently see the high importance portion without wasting time on the low importance portion. Furthermore, by changing the size, resolution, display range, etc. of the image depending on the importance, it is possible to focus attention on the highly important part.

Further, by changing the update timing of the display image according to the degree of importance, it is possible to reduce the load on the processing device or the like for the less important portion.
Of course, even if the image is of low importance, if necessary, it is possible to cancel the display according to the importance and switch to the normal display by a manual operation or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an apparatus configuration for explaining an embodiment of the present invention will be described. FIG. 1 is a diagram showing a configuration example of an image display device embodying the present invention.

The image display device 100 includes a storage medium 101,
It is composed of a processing device 102 and a display device 103. 10
4 is moving image data, and 105 is one of the images in the moving image data 104. The storage medium 101 is the moving image data 10
Accumulate 4.

The processing device 102 reads the moving image data 104 from the storage medium 101, determines the degree of importance given to each image 105 in the moving image data 104 (S1), and displays the display shape according to the degree of importance of the image 105. Alternatively, the display form is changed (S2) and displayed on the display device 103.

Next, an example of changing the display according to the degree of importance will be described. First, in the image display method according to the first aspect, as shown in FIG. 2, for example, an important image is controlled by a loud volume and an unimportant image is controlled by a low volume by the amplitude of the audio data 202 accompanying the moving image data 200. It is assumed that the importance is given to each image 201. It goes without saying that this may be the importance given not by the audio data but by the individual images separately forming the moving image data or the code structured with the moving image data.

In the moving image data 200, when 203 is an important image and 204 is a less important image, for example, when the important display 205 when the important image 203 is displayed is bright and when the less important image 204 is displayed. The non-significant display 206 may be displayed dark.

In the image display method according to the second aspect, for example, as shown in FIG. 3, in the importance 302 attached to the moving image data 300, when the individual images 301 are consecutive, 3
If 03 is scene A and 304 is scene B,
The scene A and the scene B are separated by the importance 302, and the scene A display 305 is displayed in, for example, blue, and the scene B display 306 is displayed in, for example, red. This clearly indicates the switching of the scene.

In the image display method according to the third aspect, for example, in FIG. 3, the scene A is low in importance and the scene B is low.
When the importance of is high, the scene A display 305 is fast forwarded and the scene B display 306 is slowly displayed. It goes without saying that this can also be done by changing the transfer speed from the storage medium 101 to the processing device 102 in the image display device 100 shown in FIG. 1 (for example, reproduction of a laser disk). Further, the processing device 102 reads out from the storage medium 101,
It is also possible to change the speed at which the contents are displayed on the display device 103 by the function of.

In the image display method according to the fourth aspect, for example, as shown in FIG.
When 03 is a scene A of low importance and 404 is a scene B of high importance, a scene 405 with a low importance is displayed.
Then, in a small size, the display 40 of scene B having high importance
In 6, it is displayed in a large size.

In the image display method according to the fifth aspect, for example, in FIG. 3, the scene A is of low importance and the scene B is of low importance.
Is high, when the scene A is displayed on the display device 103, the scene A display 305 is displayed at a low resolution. Thereafter, when the image display of the scene B is started, the resolution is changed and the scene B display 306 is displayed at the highest possible resolution.

In the image display method according to the sixth aspect, for example, in FIG. 3, the scene A is of low importance and the scene B is of low importance.
When the degree of importance is high, the scene A display 305 is displayed on the display device 1.
03, when displaying on the moving image data 300, only a part of the image (for example, the scanning line data of the central portion or the pixel at a predetermined position) is displayed from among the image data of the scene A. In the scene B display 306, when displayed on the display device 103, all the image contents in each image data forming the scene B are displayed on the moving image data 300.

In the image display method according to the seventh aspect, for example, when the apparatus configuration is as shown in FIG. 1 and the moving image data is as shown in FIG. 3, the scene A is of low importance and the scene B is of high importance. When the scene A display 305 is displayed on the display device 103, the screen on the display device 103 is displayed by skipping one or more images from the scene A data on the moving image data 300. When the scene B display 306 is displayed on the display device 103 without much updating, the screen is frequently updated so that all individual images from the scene B data are displayed on the moving image data 300. Similarly, when the importance of scene A is low and the importance of scene B is high, the processing device 102 that performs processing for displaying the scene A display 305 on the display device 103.
In the scene B display 306, other processing (for example, a test of the storage medium 101) is performed to direct the processing operation to another.
When performing processing for displaying on the display device 103,
The processor 102 shall be occupied by it. In this way, the load distribution is measured according to the importance of each image in the moving image data.

[0021]

As described above, according to the present invention,
When displaying moving image data, fast forward, slow display, etc. are performed depending on the importance of each image, so that it is possible to confirm the importance of the image by the display situation without looking at the display content of the displayed image. Become. Further, by changing the size, resolution, etc. according to the degree of importance and displaying it, the importance of the image can be easily confirmed.
