An image processing apparatus for storing taken image data into a memory and for reading the stored image data to effect image processing thereof, including: a storage section for storing sequence codes that indicate processing procedures of a series of image processing for the image data; an image processing section for effecting the series of image processing on the read out image data; and a sequencer for controlling the image processing section based on the sequence codes read out from the storage section in effecting the series of image processing at the image processing section, wherein the sequence codes are composed of data coding all sequence instructions corresponding to the series of image processing and are tranferred and stored collectively from CPU to the storage section before starting the series of image processing every time when the series of image processing is to be effected.
