Publication number: 20040105019Abstract: A camera equipment includes a first coder for compression-coding a picked-up image for transmission to a network and a second coder for compression-coding the image to store it in a recorder. Even when data cannot be transmitted due to the conditions of a transmission path, the compressed image data can be acquired without fail. The compressed image data before and after an abnormality can be recorded and transmitted in high image quality, and a compression scheme suitable for the expansion decoding scheme at the transmission destination can be selected. The image data generated in a camera unit is compression-coded in according to the expansion decoding scheme at the transmission destination, and transmitted to a network. The same image data thus generated is compression-coded by the second coder using a compression coding scheme in a more finely detailed fashion than that by the first coder.Type: ApplicationFiled: July 14, 2003Publication date: June 3, 2004Inventors: Shinya Imanishi, Hisao Odawa, Tetsuo Nakano
