Abstract
An image processing device includes an encoding control section which outputs a DCT start signal (DCTSTART), a quantizing start signal (QSTART), and a Huffman encoding start signal (HUFFSTART). It further includes a two-port memory, which has a writing port and a reading port independent from each other. In the case where the data for one block is written into the memory according to a column direction, and the data for one block is read out from the memory according to a zigzag-scan order or an alternate-scan order, a time difference between a time to start writing the data into the memory and a time to start reading the data from the memory is controlled such that all of the data written into the memory can be read out.
