Abstract:
1. An image processing device comprising: circuitry that performs defect correction on an image signal from a pixel array, the circuitry being configured to judge whether a target pixel corresponds to a defect condition based on a signal of the target pixel and a signal of a horizontal peripheral pixel in the image signal, the target pixel and the horizontal peripheral pixel being arranged in a horizontal direction in the pixel array, the target pixel and the horizontal peripheral pixel being pixels for detecting light of same color, and perform signal substitution on the target pixel corresponding to the defect condition, wherein the circuitry stops the signal substitution on the target pixel in a case, before judgment on the target pixel, where the circuitry judges that at least one of a vertical peripheral pixel and an oblique peripheral pixel corresponds to the defect condition, the vertical peripheral pixel and the oblique peripheral pixel being included in a line whose an image signal is input to the circuitry ahead of an image signal of a line including the target pixel, the vertical peripheral pixel and the target pixel being arranged in a vertical direction in the pixel array, the oblique peripheral pixel and the target pixel being arranged in an oblique direction in the pixel array, the target pixel, the vertical peripheral pixel, and the oblique peripheral pixel being pixels for detecting light of the same color.
