Patent number: 7031386Abstract: A transmitter is capable of compressing an incoming image with a relatively small delay time and transmit the compressed image data to a receiver. Image data contains at least i pixel values of pixels arranged in line along a single direction, each pixel value being expressed in n bits. A transmitter for compressing such image data and transmitting the image data to a receiver via a transmission path includes a blocking section, a data compression section, and a data sending section. The blocking section takes every p pixel values among the i pixel values in the image data to form a data block, and sequentially outputs a plurality of the data blocks each including the p pixel values. The data compression section reduces an amount of data from each data block outputted from the blocking section and thereby outputs a compressed block. The data sending section sends the compressed block outputted from the data compression section onto the transmission path.Type: GrantFiled: September 18, 2001Date of Patent: April 18, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akihiro Yamamoto, Susumu Ibaraki, Toshiaki Mori
