Abstract
An image processing apparatus enlarges the number of pixels of first image data made of a luminance signal and a color-difference signal in a vertical direction and in a horizontal direction, and causes each pixel to have a luminance signal and a color-difference signal to convert the image data made of the luminance signal and the color-difference signal into image data of a Bayer array made of R, G1, G2, and B signals. The image processing apparatus generates a luminance signal using one of the G1 signal and the G2 signal, the R signal, and the B signal in the image data of the Bayer array.
