Abstract
Provided are an image processing apparatus and image processing method capable of processing image data as packet data, and compressing the image data in real time to a data amount within the storage capacity of a memory. Image data in the form of packet data is divided into a plurality of blocks by a block forming circuit (), and compressed at a first compression ratio by a DCT circuit (), quantizing circuit (), and Huffman encoding circuit () for each block. A counter () measures the data amount of the compressed image data. If the measured data amount is equal to or larger than a predetermined value, the image data stored in a memory () is recompressed at a second compression ratio as a higher compression ratio by a Huffman decoding circuit (), bit shifting circuit (), and Huffman encoding circuit ().
