Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the present invention] (Industrial application field)
- This relates to an animation image processing device for producing animated images.

(Conventional technology) Conventionally, as a method of producing animation images, one method is to draw an original picture representing a series of movements in a large number of frames, store the frames on film, and then change each frame as necessary.
There is a method of performing editing such as deletion, and then taking each edited frame again on another film.

However, the above-mentioned method requires an extremely large amount of time and effort for editing and frame-by-frame shooting, and when producing a large number of films, there are problems in that image quality deteriorates due to copying.

In addition, there is a conventional method of shooting a large number of original images using a video tape recorder (VTR) and re-editing the shot videotape, but in this case, the number of frames for each frame that was shot is insufficient. In many cases, it is necessary to redo the process, and as with the above-mentioned method, there is a problem in that it also requires a great deal of time and effort.

Furthermore, methods for producing computer animation images using minicomputers have also been used in recent years,
In this case, since it is necessary to occupy an expensive mini-computer etc. for a long time, there is a problem that the production cost increases (problem to be solved by the present invention). It was developed in consideration of
The purpose of this is to simplify editing operations such as changing the display order, inserting and deleting, without using stop-motion film or VTR, and to be able to play back any number of times, without deteriorating image quality, and at low cost. To provide an animation image processing device capable of producing high-quality animation images with extremely simple operations.

(Means for Solving the Problems) A computer image processing device according to the present invention includes a storage unit that stores color image data that has been compressed in advance, and a compressed data storage that stores compression-related data regarding the color image data. a page management data generation unit that sends page-by-page management data of the compressed color image data stored in the storage unit to the compression data storage unit and performs page management of compression-related data; and a processing section that expands and sends out the compressed color image data in real time based on related data.

(Operation of the present invention) The operation of the apparatus configured as described above will be explained below. When color image data that has been compressed in advance and compression-related data indicating the compression contents of the color image data are input to the apparatus, the Color image data is stored in the storage section and compression related data is stored in the compressed data storage section.

On the other hand, the page management data generation section sends page-based management data (for example, page break data, forward direction, etc.) to the compressed data storage section.
The page-by-page compression-related data that has been managed is taken into a processing unit, and the processing unit stores the page-based compression-related data in the storage unit based on the page-by-page compression-related data. The developed color image data is developed in real time and sent to an external device.

A selector switch unit 7 appropriately switches the RGB input signals inputted through the selector switch unit 7, and each signal from the selector switch unit 7 is synthesized and sent out as a 24-bit RGB output signal. , vertical) signal to the processing section 6.

The page management data generating section 5 includes a page management data counter 10 having addition and subtraction functions and in which a desired number of pages is set based on the page designation data;
The page management data memory 12 includes a pulse signal input section 11 that sends a pulse signal to change a count value indicating the number of pages set in the page management data counter 10, and a page management data memory 12 that is controlled by the output of the page management data counter 10.

Furthermore, the storage capacities of the storage section 3 and the compressed data storage section 4 are set to, for example, 4 (megabytes).

Next, the operation of the animation image processing device 1 described above will be explained.

First, color image data that has been compressed in advance, data related to compression of the color image data, and page designation data are input to the input interface 2 via a data bus, and an address indicating the address of the color image data is input via an address bus. Data is taken into input interface 2.

Then, the color image data is input to the input interface 2.
The image data is converted into image data consisting of 8 bits each, a total of 24 bits of red signal, green signal, and blue signal, and is sent to and stored in red signal memory 3A, green signal memory 3B, and green signal memory 3C, respectively.

Further, the compression-related data is stored in the compressed data storage section 4 as 8-bit data. Further, the page designation data is sent as 8-bit data to the page management data counter 10, and the count value is set to a value indicating the desired number of pages. The set count value is sent to the page management data memory 12 and stored therein, but at this time, the once set count value can be increased or Decreased,
The values stored in the page management data memory 12 are also changed accordingly. This makes it possible to perform page management such as page breaks or fast forwarding in forward and reverse directions at any time.

The value indicating the number of pages stored in the page management data memory 12 is
The compressed data is sent to the compressed data storage unit 4, and thereby compression-related data corresponding to the number of pages is sent to the processing unit 6 on a page-by-page basis.

As shown in FIG. 1, the page designation data is directly sent to the page management data memory 12, where the data is stored, and the compression-related data whose pages are managed by this page designation data is stored in the compressed data storage section. 4 to the processing unit 6; in this case, the personal computer 20
This allows direct page management.

On the other hand, the processing unit 6 takes in the compression-related data of the designated page sent from the compressed data storage unit 4, and based on this and in synchronization with the synchronization signal, the processing unit 6 inputs the red light memory 3A, the green light memory 3B, and the green light memory 3B. The memory 3C is accessed, red lights, green lights, and green lights are processed in real time and sent to the output interface 8 via the changeover switch section 7.

The output interface 8 has expanded red, green,
Each blue signal is 8 bits each, totaling 24 bits of RG.
The B output signal is used for display on a TV monitor as display means, for example.

By the operation of this device explained above, 24 bits, that is, approximately 1
For full-color color image data containing 6.77 million colors, desired animation images can be created at any time with extremely simple operations, without using an expensive mini-computer or using conventional frame-by-frame photography on film. Can be done.

In this device, if the red, green, and blue signals are each 8 bits, one pixel based on each of these signals has 3 bytes of information, and 1 byte is allocated to compressed/expanded data. In the end, the data for -pixels is stored (file) in the storage unit 3 and the compressed data storage unit 4 as 4-byte information.In this case, for example, 640X
If a random pattern is placed all over the screen of a TV monitor with 480 pixels, one frame will have 64 pixels.
A memory capacity of 0X480X4=1.2 (megabytes) is required.

However, for things like computer graphics, which originally have a small amount of image data, it is effective to compress the data in advance and then decompress it with this device1. The image data of the logo animation is compressed to about 10 kilobytes to several hundred kilobytes, but it is effective to decompress such image data with this apparatus.

Furthermore, by performing a switching operation on the changeover switch unit 7, the image data to be developed and sent out by this device and the RGB input signal input via the RGB interface 9 are displayed in a superimposed manner on the TV monitor. It also becomes possible.
