PROBLEM TO BE SOLVED: To determine the width of a defect while taking an influence of the defect on pixels adjacent to defective pixels into consideration. SOLUTION: When a digital video signal is inputted from a solid-state imaging element 20; video information is temporarily stored in a video information storage part 11, and an output level is compared by a comparison part 13 with a threshold given by a threshold setting part 12. When the output level exceeds the threshold; a count part 14 counts pixels corresponding to the video signal as defect pixels, the defect width is expanded according to output levels of the defective pixels, and a recording part 15 writes the video information and the defect width of the defective pixels held in the video information storage part 11 as defect information to a recording medium 30.
