Abstract:
An image processing device includes a first calculation means for calculating a non-capture color signal corresponding to an H-th interpolation color for a pixel of interest, a second calculation means for calculating a non-capture color signal by multiplying a J-th capture color signal corresponding to the capture color for the pixel of interest by the ratio of the H-th two-dimensional low-pass filter output to the J-th two-dimensional low-pass filter output, and a third calculation means for calculating a non-capture color signal corresponding to the H-th interpolation color for the pixel of interest using the calculation result according to the first calculation means and the calculation result according to the second calculation means.
