ABSTRACT:
In an image processing apparatus, a defect detection unit detects a defective pixel and a defect level thereof by comparing a maximum pixel value detected at each pixel position of a plurality of images captured via an image taking operation performed a plurality of times by an image sensor with a threshold value for detecting white defective pixels, and/or by comparing a minimum pixel value detected at each pixel position of the plurality of images with a threshold value for detecting black defective pixels. A defective pixel selection unit selects a predetermined plurality of defective pixels with high defect degrees, and registers defect data associated with the predetermined plurality of selected defective pixels in the defect data table. A defect correction unit corrects pixel values of pixels of the image output from the image sensor, in accordance with the defect data registered in the defect data table.
