FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. An image processing device for detecting, from image data generated by an image sensor formed by a plurality of pixels, a signal from a defective pixel of the image sensor comprises a first determination unit for obtaining a first determination value indicating the value of the difference in signal strength between a pixel of interest and a plurality of pixels located near the pixel of interest; a second determination unit for obtaining a second determination value indicating the distribution width of the difference in signal strength between the pixel of interest and the plurality of pixels located near the pixel of interest; and a detection unit for detecting if the signal from the pixel of interest is a signal from a detective pixel using the first determination value and the second determination value, wherein the first determination unit obtains the first determination value by obtaining the difference in signal strength between the pixel of interest and each of the plurality of pixels located near the pixel of interest, obtaining from each difference value indicating the probability that the signal from the pixel of interest is a signal from a defective pixel, and multiplying the obtained values.
EFFECT: high accuracy of detecting a defective pixel.
