Abstract

A game machine for high-speed execution of iterated transformation decoding based on a drawing command or data loaded from a recording medium. The drawing command, fractal transformation parameters or data loaded from a recording medium 24 are stored in a main memory 21. A drawing texture, expanded on a VRAM 23 in a graphics processing unit 22, is iteratively transformation decoded in accordance with the drawing command or the fractal transformation parameters transferred under control of the CPU 20. The generated texture is displayed as a picture on a CRT 32 of the graphics processing unit. This realizes high-speed iterated transformation decoding of the texture and a restored picture of high picture quality while realizing iterated transformation decoding with a significantly reduced calculation volume.

Claims

1. A picture information processing apparatus comprising:

main memory means for storage of data containing fractal transformation parameters;

picture processing means for effecting iterated transformation decoding using the fractal transformation parameters stored in the main memory means to generate a picture;

picture storage means for expanding a picture generated by said iterated transformation decoding;

display control means for display-controlling the generated picture;

actuation inputting means; and

control means for controlling the processing by said picture processing means and the display operation by said display control means responsive to an actuating input from said actuation inputting means, wherein said picture processing means includes demultiplexing means for demultiplexing input bitstream data, domain block generating means for generating blocks based on the position information of the domain block, picture transformation and generating means for transforming and generating pictures based on transformation parameters, initial picture restoring means for restoring the initial picture used for decoding, a picture memory for storage and saving of the transformed domain block pictures and control means for effecting decoding iteration control.

2. A picture information processing apparatus comprising:

main memory means for storage of data containing fractal transformation parameters;

picture processing means for effecting iterated transformation decoding using the fractal transformation parameters stored in the main memory means to generate a picture;

picture storage means for expanding a picture generated by said iterated transformation decoding;

display control means for display-controlling the generated picture;

actuation inputting means; and

control means for controlling the processing by said picture processing means and the display operation by said display control means responsive to an actuating input from said actuation inputting means, wherein, at the time of iterated transformation decoding by said picture processing means, part of the plural pixels making up a transform unit in a domain block is directly copied in a range block to effect contractive picture transformation, wherein the pixels copied in the range block is extracted in plural pixels as transformation unit in the domain block from different positions depending on the number of times of the iterated transformation.

3. A picture information processing apparatus comprising:

main memory means for storage of data containing fractal transformation parameters;

picture processing means for effecting iterated transformation decoding using the fractal transformation parameters stored in the main memory means to generate a picture;

picture storage means for expanding a picture generated by said iterated transformation decoding;

display control means for display-controlling the generated picture;

actuation inputting means; and

control means for controlling the processing by said picture processing means and the display operation by said display control means responsive to an actuating input from said actuation inputting means, wherein said picture processing means includes initial picture restoring means for restoring an initial picture and generates a picture by iterated transformation decoding employing the fractal transformation parameters based on the restored initial picture, and

wherein, when effecting zoom display using enlarged pictures of plural stages as a picture generated on iterated transformation decoding, an enlarged picture is generated by synthesizing a first picture generated on iterated transformation decoding based on another enlarged picture generated prior to said enlarged picture and a second picture generated by iterated transformation decoding based on said initial picture.
