Patent ID: 7375749

Claim:
An image sensing apparatus comprising: a first determination device which determines whether or not a pixel of interest subjected to defective pixel detection out of a plurality of pixels of an image sensing element is a defective pixel candidate; a second determination device which determines whether or not the pixel of interest is a defective pixel when the pixel of interest is determined as the defective pixel candidate by said first determination device; and a correction device which corrects the pixel of interest when the pixel of interest is determined as the defective pixel by said second determination device, wherein said first determination device determines that the pixel of interest is the defective pixel candidate when a difference between a signal level of the pixel of interest and signal levels of a plurality of neighboring pixels existing around the pixel of interest is larger than a predetermined threshold value, and wherein said second determination device refers to the neighboring pixels of the pixel of interest and determines that the pixel of interest is not the defective pixel in a case that a pixel, which is determined as the defective pixel candidate by said first determination device, exists in the neighboring pixels, and determines that the pixel of interest is the defective pixel in a case that a pixel, which is determined as the defective pixel candidate by said first determination device, does not exist in the neighboring pixels.
