Abstract: PURPOSE: To efficiently execute the function of texture mapping by providing plural plotting processors which are respectively connected to one of plural texture memory clusters and generate data to be displayed in a pixel through the use of a texture value ax against the pixel. CONSTITUTION: When a certain kind of display is executed in a display device 11, plotting is instructed to a graphic sub-system 3, a geometry calculating part 5 executes polygon-division, a coordinate on a screen at the vertex of a polygon is obtained and the coordinate of a texture image in the coordinate is calculated. When color is designated, moreover, the color information is also calculated and a luster calculating part 7 calculates the coordinate on the screen and the coordinate of the texture image at every pixel inside the polygon. A texture calculating part 9 generates the texture value against the pixel from the coordinate of the texture image and the magnifying/reducing rate LOD of the pixel.

Abstract: PURPOSE: To display a source image while extending it without any sense of incompatibility by performing screen interpolation without using any expensive line buffer, etc. CONSTITUTION: When extending a frame for the unit of a data stream composed of four pieces of piexl data vertically arranged as shown in (A) to a frame for the unit of a data stream composed of seven pieces of pixel data as shown in (B), for example, this frame is converted to frames for the unit of a data stream composed of seven pieces of pixel data interpolating the data of preceding or following picture elements at the interpolate positions (shown by symbols *) as shown in (C) and (D) and these frames are alternately displayed on a display device at prescribed time intervals (extremely short time intervals). Therefore, the extended image with no sense of incompatibility are seemed to be always displayed by the phenomenon afterglow for human sight.

Abstract: PROBLEM TO BE SOLVED: To reduce processing time to decode encoded data where a plurality of symbols are each replaced by a bit string.SOLUTION: Every time a bit length is input into a Huffman table decoding circuit, a counter 32 outputs a character code corresponding to the bit length as a Data In signal, a pointer table 33 outputs a number of symbols and a pointer corresponding to the bit length, and an addition circuit 34 adds them to output the result as an Insert Address signal. A shift memory circuit 31 with an insert function thus does not move character codes at addresses previous to an address by the Insert Address signal but stores the character code by the Data In signal at the address by the Insert Address signal and shifts back character codes at addresses at and subsequent to the address by the Insert Address signal.

Abstract translation: 要解决的问题：为了减少对多个符号各自被位串替换的编码数据进行解码的处理时间。 解决方案：每当将比特长度输入到霍夫曼表解码电路中时，计数器32输出与比特长度相对应的字符码作为数据输入信号，指针表33输出多个符号和相应的指针 并且加法电路34将它们作为插入地址信号输出以输出结果。 因此，具有插入功能的移位存储器电路31不会通过插入地址信号移动地址之前的地址处的字符代码，而是通过插入地址信号将该字符代码存储在地址处的数据输入信号，并将字符代码在 通过插入地址信号在地址之后的地址。 版权所有（C）2012，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an external storage device which is provided with a plurality of recording media to exhibit their features and is excellent in their availabilities, and to provide an external storage device control method, a program, and a recording medium. SOLUTION: The external storage device 110 for storing data received from the outside for each data block is provided with a determination part 275 for determining whether or not it is possible to record the data blocks by using a specific data pattern, and an access processing part 277 for storing identification information for identifying the specific data pattern instead of storing the contents of the data blocks in the external storage device 110 when it is determined that it is possible to record the data blocks by using the specific data pattern by the determining part 275.
