Correction processing of crosstalk amount is adaptively performed even under conditions where optical conditions, such as a lens to be used, are unknown. Relative change among crosstalk amount is calculated based on a proportion of the sum of signal amount of RGB signals as to the signal amount of white signals. Next, upon calculating crosstalk correction coefficients corresponding to the current crosstalk amount from a relational expression of crosstalk correction coefficients obtained beforehand and crosstalk amount, the signal of a pixel to be corrected is corrected by subtracting several tenths of adjacent pixel signals from the signal of the pixel to be corrected, as crosstalk amount. |
