APPARATUS FOR CORRECTING CHANNEL SENSITIVITY AND LENS SHADING OF A PHOTOGRAPHED IMAGE, AND A METHOD THEREOF, PARTICULARLY FOR REDUCING THE NOISE RESULTING FROM THE DIFFERENCE BETWEEN GR AND GB CHANNELS
APPARATUS FOR CORRECTING CHANNEL SENSITIVITY AND LENS SHADING OF A PHOTOGRAPHED IMAGE, AND A METHOD THEREOF, PARTICULARLY FOR REDUCING THE NOISE RESULTING FROM THE DIFFERENCE BETWEEN GR AND GB CHANNELS
PURPOSE: An apparatus for correcting channel sensitivity and lens shading of a photographed image, and a method thereof are provided to enhance the accuracy of correction by defining a channel correction function proper to a sensor.;CONSTITUTION: A captured-image input unit receives a white chart and a general captured-image, and a lens shaking correction function generation and coefficient extraction unit extracts a coefficient by generating a lens shaking correction function based on the white chart captured image. A channel difference correction function generation and coefficient extraction unit extracts a coefficient by generating a channel difference correction function based on the white chart capture image. A memory stores the extracted channel difference and the lens shading correction coefficient.;COPYRIGHT KIPO 2011
