Title: Masaru Onishi: Innovator in Image Processing Technology
Introduction
Masaru Onishi is a notable inventor based in Kamakura, Japan. He has made significant contributions to the field of image processing, holding a total of 6 patents. His work focuses on improving the efficiency and effectiveness of image data compression and processing.
Latest Patents
Onishi's latest patents include an innovative image processor that utilizes image data compression coding of a fixed compression rate. In this design, the data of one color of image data is stored in a coding memory without coding when compression is unnecessary. When compression is required, the data is encoded by an encoder with a compression rate of 4, allowing for the storage of coded data for four colors: cyan, magenta, yellow, and black. This method enables effective use of coding memory without relying on a fixed disc unit. Another significant patent is an image processing device designed for use in scanners, printers, and digital copying. This device features an encoder that encodes inputted image data in the form of fixed-length compression. The encoded data is stored in a hard disk through an encoded data buffer, allowing for constant speed storage and minimizing the capacity of the buffer. This innovation leads to a cost-effective image processing device.
