摘要

This invention does not unconditionally fix the upper limit of encoding but adjusts it in accordance with the size of an input image, thereby effectively utilizing a memory and maintaining high image quality regardless of an image size. In this invention, input image data is compression-encoded by an encoder 102 and stored in first and second memories 104 and 106. An image size detector 111 detects the size of the input image data. An encoding sequence controller 108 determines the upper limit of the code amount of the input image data currently being encoded, and monitors whether this upper limit is exceeded. Upon determining that the upper limit is exceeded, the encoding sequence controller 108 sets encoding parameters of the encoder 102 to set a higher compression ratio, and continues the encoding. Encoded data before this determination is decoded and re-encoded by a re-encoder 109 so as to have a compression ratio higher than before.
