Abstract
An image processing device, which includes processing circuitry configured to cause the image processing device to first detect a first bad pixel based on first image data, correct the first bad pixel based on first values of first peripheral pixels in response to the first detection to obtain a first correction result, the first peripheral pixels being peripheral to the first bad pixel, second detect the first bad pixel and a second bad pixel based on the first image data, the second bad pixel being adjacent to the first bad pixel, correct the second bad pixel based on second values of second peripheral pixels to obtain a second correction result, the second peripheral pixels being peripheral to the second bad pixel, and correct the first bad pixel by using the first correction result stored in a buffer in response to the second detection.
