PROBLEM TO BE SOLVED: To provide an image processor which is easily structured and designed and can change parameters with respect to compression in units of pixel blocks such as a tile. SOLUTION: The image processor includes: a division section 2112 for dividing image data received from an image input section such as a scanner 2070 in units of prescribed pixel blocks; an image compression section 2106 for applying compression coding to the divided pixel block; and an image storage section 2002 for storing compression coded information subjected to compression coding, and the division section, the image compression section, and the image storage section make communication with each other by using packet data. Then the division section 2112 discriminates the attribute of the pixel block in the case of dividing the received image data into the prescribed pixel block and outputs information with respect to the produced attribute as attached information together with data of the pixel block as packet data. Further, the image compression section determines the parameters for compression coding according to the attribute information in the packet data outputted from the division section and applies compression coding to the data of the pixel block included in the packet data. The storage section stores the packet data compressed by the image compression section. COPYRIGHT: (C)2004,JPO
