Patent ID: 8736696

Claim:
An image processing apparatus comprising: a control unit being configured to have an imaging unit take a first image of an object image with a center position of view angle to the object image being a first position to obtain a first image data including a first brightness characteristic, and have the imaging unit take a second image of the object image with a center position of view angle to the object image being a second position different from the first position to obtain a second image data having a peripheral area at the center of the first image data and including a second brightness characteristic; a computing unit being configured to determine a first difference value between brightness of the first image data and brightness of the second image data in an overlap area of the first image data and the second image data; a generating unit being configured to generate, based on the first difference value, a second difference value relative to a brightness at the center of the first image data, and generate, based on the second difference value, a brightness correction parameter for the first image data; and a correction unit being configured to correct the brightness of each pixel of the first image data according to the brightness correction parameter.
