Embodiment Construction
[0043] In one embodiment of the present invention, it is disclosed that when there are dead pixels in the same type of pixel group in the 5x5 window based on the mathematical formula calculation for Gr and Gb inter-pixel offset correction, by and except the dead pixels This is an inter-pixel offset correction method for an image sensor where offset correction occurs by calculating the same type of normal pixels.
[0044] In addition, an embodiment of the present invention discloses that the technical composition of identifying the edge (Edge) area is added to the inter-pixel offset correction method according to an embodiment of the present invention, and the edge area is bypassed during offset correction. A method of deskew that maintains sharpness in parts with contrast between light and dark.
[0045] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
