PROBLEM TO BE SOLVED: To provide an image processing system capable of coping with various data reading patterns of an image sensor.SOLUTION: Both lowest order bits of count values of an H counter 1 and a V counter 2 are added together, to generate a timing signal CLBASET that specifies a repetition range of 2×2. For each input channel, a timing register TRCH is assigned. Each of the timing registers includes four registers that store the data which decides color of respective places in the repetition range. A selector TSELCH selects an output of the timing register on the basis of the signal CLBASET, and generates signals C0CS and C1CS which specify a color of the pixel at a certain time point independently for each input channel. A register BLR which stores black level correction data of each color is common to respective input channels. A black level correction data at a certain time point is selected, independently for each input channel, by the corresponding signals C0CS and C1CS, and is inputted in a pre-processing circuit of each input channel. |
