摘要

This invention reliably encodes an image while continuously inputting the image with a relatively simple configuration. For this purpose, in this invention, input image data is encoded by an encoder ( 102 ) and stored in first and second memories. An encoding sequence controller ( 108 ) monitors the code amount. Upon determining that the code amount has reached a set value, the encoding sequence controller discards the data in the first memory and instructs the encoder ( 102 ) to increase the quantization step and continue encoding. Preceding encoded data is stored in the second memory. The encoded data is re-encoded by a re-encoder ( 109 ) using the same quantization step as that of the encoder ( 102 ) after the parameter is changed. The re-encoded data is stored in the first and second memories. The quantization steps set in the encoder ( 102 ) and re-encoder ( 109 ) at this time have such values that re-encoding by the re-encoder ( 109 ) is ended before time when the code amount reaches the set value again.
