摘要： In an image processing device, an image data generation unit generates image data of an object to be displayed on a display device in each vertical scan period. A memory management unit manages a working memory for storing the image data generated by the image data generation unit. The memory management unit selects a storage region of the working memory for storing image data when the same is generated and stores the generated image data in the selected storage region, and releases another storage region which stores image data that has been used for display on the display device, thereby allowing said another storage to store new image data. A drawing unit reads image data required to draw one line on the display device in each horizontal scan period from the working memory through the memory management unit, then generates the image data of one line based on the read image data, and stores the generated image data of one line in a line buffer. A controller sequentially instructs the image data generation unit to generate image data of each object before image data of each object is displayed on the display device in each vertical scan period.

摘要： A polygon drawing apparatus and method draws a polygon by performing intensity processing on a polygon to be drawn so as to smoothly draw each edge portion of the polygon, by performing intensity processing on a polygon to be drawn so as to smoothly draw each edge portion of the polygon. Line intersection data associated with an intersecting portion between each edge of the polygon to be drawn, and each scan line is derived, which includes a first pair of outside intersection and inside intersection that represent intersecting positions between each scan line and one edge located on an upstream side as viewed in a scanning direction, a second pair of outside intersection and inside intersection that represent intersection positions between each scan line and one edge located on a downstream side as viewed in the scanning direction, an increasing rate at which an intensity value increases from the outside intersection to the inside intersection of the first pair, and a decreasing rate at which the intensity value decreases from the inside intersection to the outside intersection of the second pair. The intensity value to be given to each portion of the polygon in the scanning direction with respect to each scan line is sequentially calculated based on the line intersection data obtained for each scan line.

摘要： A display data compression method can execute both irreversible compression and reversible compression, wherein display data are divided into a plurality of two-dimensional blocks, each of which is subjected to compression. In the irreversible compression, display data of each block are subjected to discrete cosine transform, quantization using a quantization table, one-dimensional rearrangement, and Huffman coding using one-dimensional Huffman table. In the reversible compression, display data of each block are subjected to scanning and compression, which are repeatedly performed by changing the scanning method therefor, so as to produce compressed data having the smallest number of effective bits. In expansion, the compressed data are decoded so that the decoded data are combined together over the blocks, thus restoring the original display data.

摘要： A texture mapping device is employed in a computer graphics system that visually displays an object in a three-dimensional manner. Herein, textures representing graphics patterns are put onto interior areas of the polygons which form a surface of the object displayed on a screen of a display device. A projective image is created by projecting a polygon (e.g., triangle) originally placed in a three-dimensional space onto a screen coordinates system. A texture memory stores texture data representing an image of texture with regard to a texture coordinates system. Screen addresses of the screen coordinates system as well as texture addresses of the texture coordinates system are calculated with respect to at least a start point and an end point corresponding to points of intersection formed between a horizontal scanning line of the screen and one side of the polygon. The device rounds off the screen addresses to produce integer screen addresses corresponding to locations of pixels which are placed in proximity to the points of intersection on the screen coordinates system. The texture addresses are corrected on the basis of differences between the screen addresses and integer screen addresses. The device rounds off the corrected texture addresses to produce integer texture addresses. Using the integer texture addresses, the texture data are read from the texture memory. Then, the texture data are written into the display memory at locations defined by the integer screen addresses. Thus, it is possible to perform texture mapping accurately with respect to pixels on the screen without positional deviations.

摘要： An image processing apparatus processes compression encoded data of a moving picture and outputs image data divided into a plurality of frames for displaying of the moving picture on a display device. A host CPU outputs a decoding command and a drawing command separately from each other. The decoding process on the compression encoded data can be performed in an independent manner from the drawing process of reflecting the image data, which are the decoding results, on the display object. At this time, a display control section executes the drawing process based on the image data stored in a ring buffer in accordance with the drawing command. Therefore, the host CPU can freely control timings at which the moving pictures are displayed on the display device.
