Abstract
An image processing apparatus performs image processing on image data including blinking defective noise generated by an image sensor including pixels configured to generate a signal, and readout circuits configured to read out the signal as a pixel value. The image processing apparatus includes: an acquisition unit configured to acquire noise information including position information of a pixel in which there is a possibility that blinking defective noise attributed to the readout circuit occurs; a direction determination unit configured to determine, based on the noise information, and pixel values of neighboring pixels surrounding a pixel of interest in an image corresponding to the image data, a direction in which pixel values having highest correlation with a pixel value of the pixel of interest are consecutively arrayed; and an image processor configured to perform image processing on the image data based on a determination result.
