Patent ID: 8416322

Claim:
A method of processing image data including chromatic aberration of magnification, which is obtained from a fisheye optical system, the method comprising: correcting the chromatic aberration of magnification by performing a coordinate transformation with respect to the image data based on { X = x + ax Y = y + by where x and y represents coordinates of a transformation destination with a center of a screen as an origin, X and Y represents coordinates of a transformation source with the center of the screen as an origin, and a and b are coordinate transformation coefficients, wherein the correcting step includes, excluding a specific color component from the coordinate transformation; obtaining a correction amount based on coordinate data of the specific color component, the correction amount being Δx=ax and Δy=by in an x-direction and y-direction, respectively; and performing the coordinate transformation of color components, including at least a first color component and a second color component, each of the first color component and the second color component being a component other than the specific color component, wherein the performing step includes, obtaining a first value by subtracting the correction amount from the coordinate data of the specific color component, the first value being designated as coordinate data for the first color component; and obtaining a second value by adding the correction amount to the coordinate data of the specific color component, the second value being designated as coordinate data for the second color component.
