Abstract
An encoder () encodes image data using a first parameter Q, and a re-encoder () re-encodes the encoded result of the encoder () using a second parameter Q. When the encoded data size obtained by the encoder () exceeds a predetermined size, Qis replaced by Q, and encoded data streams previously encoded by the re-encoder () are saved in a buffer () as those encoded by the encoder () after the parameter is changed. Upon executing a re-encoding process, the re-encoder () re-encodes encoded data streams previously encoded by the re-encoder () using a parameter that can assure a higher compression ratio than Q
