In image input devices such as digital still cameras, processing is speeded up and power consumption is reduced by arranging in a RPU ( 23 ) performing real time processing of a pixel data from a CCD ( 21 ), such that only special exceptional image processing not being prepared previously is subjected to a software program processing in a CPU ( 24 ) and, in post processing in which a general image processing is carried out, a pixel data temporarily stored in a main memory ( 29 ) is inputted again to the RPU ( 23 ) and then processed. This enables to sharply speed up processing, and minimize a prolonged processing in the CPU ( 24 ) to reduce power consumption, when compared to the case of executing by software problem processing.
