Document Type and Number:
Japanese Patent JP3984936
Kind Code:
B2
Abstract:
An image sensing apparatus includes a solid-state image sensing element having a plurality of pixels which output image sensing signals, a first determination device which determines whether a pixel of interest is a defective pixel candidate, by comparing the signal level of the pixel of interest subjected to defective pixel detection out of the plurality of pixels of the solid-state image sensing element, and the signal levels of a plurality of peripheral pixels around the pixel of interest, and a second determination device which, when the-first determination device determines that the pixel of interest is the defective pixel candidate, determines whether the determination result representing that the pixel of interest is the defective pixel candidate is erroneous detection, on the basis of the determination result of the first determination device representing whether a plurality of peripheral pixels around the pixel of interest are defective pixel candidates.
