ABSTRACT:
A defect pixel correction circuit that can easily determine a defect of an image sensor that has the defect that ranges to one direction and replace with the correcting pixel is provided. The defect pixel correction circuit1includes: a defect pixel determination unit10configured to determine whether a noteworthy pixel oo is a defect pixel referring to a referring pixels ko, mo, qo and so that excludes the noteworthy pixel oo, the referring pixels centering on the noteworthy pixel oo and lining up in one direction; and a defect pixel correcting unit20configured to generate a correcting pixel value on the basis of the referring pixels mo and qo, and replace the noteworthy pixel value that is pixel value of the noteworthy pixel oo with the correcting pixel value, when the noteworthy pixel oo is a defect pixel.
