The present invention provides an image processing apparatus for detecting, from image data generated by an image sensor constituted by a plurality of pixels, a signal from a defective pixel of the image sensor, including first determination means for obtaining a first determination value indicating a magnitude of a difference in signal level between a pixel of interest and a plurality of pixels located in the neighborhood of the pixel of interest, second determination means for obtaining a second determination value indicating a width of distribution of the difference in signal level between the pixel of interest and the plurality of pixels located in the neighborhood of the pixel of interest, and detection means for detecting whether or not the signal from the pixel of interest is a defective pixel signal, using the first determination value and the second determination value. |
