PROBLEM TO BE SOLVED: To provide an image processing apparatus compatible with various data read pattern of an image sensor. SOLUTION: Both lowest bit of the count values of an H counter 1 and a V counter 2 are added together to generate a timing signal CLBASET which specifies repetition range of 2×2. A timing register TRCH is arranged for each input channel. Each timing register comprises four registers to store data that determines color of each place within repetition range. A selector TSELCH selects an output of the timing register based on the signal CLBASET, and generates signals C0CS, C1CS that specify color of the pixel at an independent time point for each input channel. A register BLR where a black level correction data of each color is stored is common among the input channels. It is independently selected by the signals C0CS and C1CS corresponding to the black level correction data at a certain time point for each input channel, and is input in a pre-process circuit of each input channel.
