摘要: A lens shading correction method and apparatus are provided for removing vignetting occurring in digital images due to shading. white image captured by an pickup device unit is separated into reference corresponding color channels. center having a maximum light intensity estimated each of the images. Multiple segments on defined. value pixel constituting calculated using intensity. function segment derived value. Vignetting general received processing mode removed, multiple functions.
