ABSTRACT:
Adaptive luminance interpolation processing in a signal processing apparatus for acquiring an image signal from an image sensing element having color filters and processing the image signal is described. An adaptive luminance interpolation circuit determines the correlation of the image signal in the vertical and horizontal directions, and interpolates the luminance signal of the image signal in a direction in which the correlation is higher. The chroma signal of the image signal is interpolated regardless of the correlation direction. The chroma signal is processed by a color conversion matrix circuit for performing signal processing of suppressing a false color in the vertical direction or a color conversion matrix circuit for performing signal processing of suppressing a false color in the horizontal direction, switched by a matrix switching circuit based on the interpolation direction.
