Abstract
To achieve more appropriate interpolation of a missing pixel, an image is input to a processing section for interpolation. The interpolation is applied utilizing image data of pixels located around the pixel to be interpolated. Specifically, correlations between the image data of the pixels to be interpolated, and pixel data in a horizontal direction, vertical direction, and diagonal direction, are compared to one another; pixel data having stronger correlation is used for the interpolation. Correlation between the image data of the pixels to be interpolated and which direction is strong is determined, so that different weighting for interpolation is used accordingly.
