Abstract
An image processing apparatus including a processor including hardware, the processor being configured to: detect a defective pixel from among the multiple pixels; calculate a level of a pixel value of the defective pixel; compare the calculated level of the pixel value of the defective pixel with a threshold to determine whether a defective pixel that is stored in a storage is to be corrected, the threshold being determined based on a brightness that is calculated from pixel values close to a defective pixel and on any one of an exposure time of image data corresponding to a defective pixel on which a determination is to be made, a value of gain, and variation in pixel value among pixels surrounding the defective pixel on which a determination is to be made; and interpolate the pixel value of the determined defective pixel that is to be corrected.
