PROBLEM TO BE SOLVED: To provide an imaging device that attains effective defect correction where deterioration in the resolution cannot substantially be caused by utilizing information of effective pixels without waste, so as to minimize the deterioration in the S/N without the need for provision of a complicated hardware circuit needing much load. SOLUTION: The imaging device the sensitivity of which is enhanced through summation of pixel values, is provided with a read function that attains summation reading, where pixel information items of a unit pixel of a pixel in the unit of photoelectric conversion of a CCD image pickup element 105 picking up an object are summed. In a 1st photographing mode corresponding to an exposure time less than a prescribed time, summation reading can generate pixel information of pixels being after the summation. In a 2nd photographing mode corresponding to the exposure time being the prescribed time or over, non-summation reading is conducted, summing pixel information items of read unit pixels by an external arithmetic means generates pixel information for the pixels. In the case of the summation in the 2nd photographing mode, a defect compensation processing is conducted where the defect pixel information in the pixel information of the unit pixel is supplemented by pixel information of adjacent non-defective unit pixels. |
