发明名称 Lens shading correction for autofocus and zoom lenses
摘要 In one embodiment of the invention, there is provided a method of correcting a captured image for lens shading artifacts, the captured image being captured by an image capture system, the method comprising: determining a function L(x, y) being a lens shading correction function to be applied to images captured by a lens of the image capture system in order to correct for lens shading artifacts; if a focal length associated with the captured image is less than a focal length associated with, the function L(x, y) then cropping the function L(x, y) based on the focal length associated with the captured image; and scaling the cropped function L(x, y) to a size of the tin-cropped Junction L(x, y).
