Description

Detailed Description of the Invention (Industrial Application Field) The present invention moves and displays a moving image in an arbitrary area of an image display section using image data input directly from an external device or via a transmission medium. . The present invention relates to a moving image display device.

(Prior Art) Conventionally, in order to display a moving image, compressed image data consisting of still images and moving images is input from an external device to a microcomputer (CPU), and according to the command information, the still image data is first stored in a graphic memory. The still image is displayed by writing the still image to the background memory, and then the part of the still image to be displayed as a moving image is stored in the background memory, the video compressed data is expanded, and it is stored in the expanded memory. The moving image is displayed by mixing the moving image data with the data in the background memory and writing the mixture into the graphic memory based on the silhouette data of the expanded data.

(Problem to be Solved by the Invention) However, when displaying a still image by inputting compressed image data from an external device as described above, it takes several seconds to display the still image. If a moving image is displayed within a still image area after the display has finished, the image suddenly starts moving, resulting in an unnatural moving image display.

(Means for Solving the Problems) The present invention solves the above drawbacks by providing a cPU that controls the movement display procedure of video data, and a video memory that stores compressed image data input from an external device via the CPU. and an expansion memory that expands and temporarily stores the compressed data.
A background memory that temporarily stores background image data, a video processor that controls display of images, and a graphics memory that is connected to the video processor and stores images;
An image display that inputs background data and silhouette data for moving images from an external device, obtains moving image data from the currently displayed still image, and moves within the 5-image display area. The problem can be solved by using a device.

(Function) According to the present invention, even if it takes time to display a still image, a moving image portion is inserted into the still image by an external device in advance, and the background image and silhouette data of the moving image portion are input as image data. As a result, moving video display becomes natural, and the drawbacks of conventional devices can be eliminated.

(Example) Hereinafter, the present invention will be explained in detail by way of an example using the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.
1 is a cPU that controls video processing procedures; 2 is a video memory (hereinafter referred to as A-RAM) that stores compressed image data from an external device via the CPU; 3 is the A-R
AM 2 is a deployment memory (hereinafter referred to as T-RAM) that expands the memory contents of 2 and temporarily stores the data, and 4 is a background memory (hereinafter referred to as B-RAM) that temporarily stores background image data.
5 is a video processor (hereinafter referred to as VDP) that controls image display; 6 is a graphic memory (hereinafter referred to as G-RAM) connected to the VDP 5 and stores images. Further, 7 is an image display section for displaying the stored contents of the G-RAM 6. The operation of the present invention constructed in this way will be explained with reference to FIG.

In other words, Figure 2 is a diagram showing the state in which the moving image moves.
8 indicates the screen coordinates of the image display section 7 that displays the image data of the G-RAM 6 in correspondence with the coordinates, and XO*
Yo is the origin coordinate, and Xoyy++ is in the still image area.
The video part is inserted at the point inside.

Image data received from an external device (not shown) is expanded and divided into background image data and silhouette data S, and is stored in the T-RAM 3. The G-RAM
The moving image portion is extracted from 6 and once stored in B-RAM 4, and then replaced with the background image data in T-RAM 3. Next, the background image data is stored in the G-RAM 6.
Write to the XnvVn position of
Data at the Y@ position is stored in B-RAM as background image data.
Store it in 4. Based on the silhouette data of T-RAM 3, the video data of T-RAM 3 and the background image data of B-RAM 4 are mixed, and the
A moving image is displayed by writing in the Ywa position.

FIG. 3 is a flowchart of the above-mentioned processing procedure. First, in step a, the present invention inputs compressed image data consisting of a still image and a moving image (background image) from an external device to the A-RAM 2.
), then the still image data is developed and written into the G-RAM 6 to display the still image (step b). Next, in steps c and d, the unused area size in B-RAM 4 is checked, and if the background image data cannot be stored, the display is terminated.
If it can be stored, proceed to the next step e. In step e, data at a specified position from the still image of G-111AM 6 is stored in B-RAM 4 based on the video delivery information. In step f, the moving image (background image) data stored in the A-RAM 2 in step a is expanded, separated into a moving image (background image) portion and a silhouette portion, and stored in the T-RAM 3. Next, in step grh, it is checked whether the data expanded with the data f is moving image data or background image data, and if it is background image data, it jumps to data k, and if it is moving image data, it proceeds to the next step i. In step i, the background image data in B-RAM 4 and the moving image data in T-RAM 3 are mixed and transferred to G-ARM 6 based on the silhouette data in step f.

Step j displays the moving image written in step i″'Q together with the still image.

In the step, video data of B-RAM 4 and T-RA
The background image data of M3 is exchanged and stored. step e
checks the movement status of the moving image, and if the moving is completed, the process is terminated, and if it is not completed, in the next step m, the process waits for a certain period of time for displaying the moving image.

In step n, the background image data stored in the B-RAM 4 is returned to the position where the moving image is displayed in the G-RAM 6, and the moving image is erased. In step 0, new moving point information is obtained from the control command. In step p, new background image data is obtained from the G-RAM 6 from the moving point obtained in step 0 and stored in the B-RAM 4. The process from step i to step p is repeated, thereby making it possible to display a moving image.

That is, the present invention adds the processing of steps g, h, and k, that is, the processing of determining whether or not it is background image data, to the conventional device, so that even if it takes time to display a still image, the subsequent moving image can be displayed. Since the moving image portion is inserted into the still image in advance, the moving image does not suddenly become a moving image, and therefore the moving image is displayed moving in a natural situation.

(Effects of the Invention) As is clear from the description of the present invention using one embodiment, since moving images are displayed naturally, the present invention is very effective when applied to the display of tape images.
