Patent number: 7965776Abstract: The invention is directed to a technique for realtime processing of photographed pictures with less memory requirements. An image compressor compresses unit images, and so on of a given source picture individually. By converting reference data of compressed unit images and so on, the image compressor creates compressed data of the source picture. From the image compressor, a reference parameter generator receives original reference data corresponding to each unit image and so on having undergone the reference data conversion. An image decompressor retrieves a plurality of compressed unit images, and so on in an order suitable for a specified image editing operation. The image processor outputs the decompressed unit images after editing them to effect the specified image editing operation.Type: GrantFiled: February 6, 2006Date of Patent: June 21, 2011Assignee: Fujitsu Semiconductor LimitedInventors: Kenichiro Kuroki, Yuji Tajima, Nobutaka Yamagishi

Publication number: 20060203002Abstract: In order to solve a problem that when displaying a plurality of overlapped windows, the occupied ratio of a common data bus increases, there is no way but to improve the operating speed of the data bus in order to display data as much as possible and as a result, power consumption increases, only data actually displayed visibly on a screen is read by slicing the screen at the vertex coordinates (X, Y) of overlapped windows and setting a starting address in VRAM and a step width for each sliced rectangular area, instead of reading the display data in all windows from the VRAM.Type: ApplicationFiled: July 5, 2005Publication date: September 14, 2006Inventors: Kenichiro Kuroki, Seiji Kawamura
