PROBLEM TO BE SOLVED: To provide a digital image pickup device in which an arithmetic time can be shortened, and the next photographing can be quickly prepared by executing an end batch operation with one central picture element of a block constituted of plural picture elements at the time of operating distortion correction by an arithmetic operation. SOLUTION: The coefficient of an approximate polynomial indicating image height versus distorton curves being the lens performance characteristics of a photographing lens 1 is stored in as ROM 7. The digital data of a subject fetched from the photographing lens 1 are temporarily stored in a buffer memory 5. The arithmetic operation of the approximate polynomial is executed by using the coefficient stored in the ROM 7 and the coordinate data of a picture element central to a block constituted of the plural picture elements of the digital data stored in the buffer memory 5 by an approximate polynomial arithmetic part 6a. Thus, the distortion correction of the block of the digital data stored in the buffer memory 5 can be attained with one central correction quantity. |
