Latest Patents

Yasumasa Hayashi holds a patent for a "Method of rotating image data in a partitioned display buffer." This method involves operating a graphics system where a host processor sends image data and orders to a display terminal. The image orders specify the position and size of a source rectangle area and the destination rectangle area in an image storage memory. The image data from the source rectangle area can be rotated by angles of 90 degrees, 180 degrees, or 270 degrees before being stored in the image storage memory. This memory acts as a buffer for a display unit, which shows the image data from the destination rectangle area. The image storage memory is divided into areas of K bits, and the image data is rotated in blocks of K times K bits.
