Abstract
A proposition is to perform a detection of a position shift amount between images which are anteroposterior in a chronological order with high accuracy. Therefore, in an image processing apparatus, a unit A performs a geometric transformation on a pixel group α in an imageusing an input position shift amount as a parameter, and calculates a gain based on a luminance difference between the pixel group α in the imagebeing performed the transformation and pixels in an imageexisting at an identical coordinate as the pixel group α. Besides a unit B multiplies an input gain to the imageand calculates a position shift amount between the imageand the image. A detecting unit executes the unit A and the unit B for at least one time or more.
