Abstract
An image processing apparatus and an image processing method are provided that enable accurate detection of color shift occurring due to chromatic difference of magnification. An image processing apparatus includes an image signal extraction unit to extract at least a part of an image signal from image data based on signal characteristics of the image signal, an edge detection unit to detect an edge portion in an image by the image data from a detection target that is the extracted image signal based on a luminance value of the image signal, and a color shift amount detection unit to detect a color shift amount by calculating a correlation of at least two color components contained in the image signal according to a distance from a reference position in the image.
