Abstract
An image interpolating device comprises a color filter, in which R, G, and B color filter elements are disposed in a checkerboard arrangement, and an imaging device which generates R, G, and B-signals corresponding to the color filter elements. In an interpolation process, the difference between a first comparative value V and a second comparative value V is compared. V is determined using color signals of pixels offset in the right and left directions to an objective pixel. V is determined using color signals of pixel offset in the upper and lower directions to the objective pixel. When V is less than V , an arithmetic mean of G-signals of pixels offset in the right and left directions by one pixel is obtained as an interpolated G-signal. When V is not less than V , an arithmetic mean of G-signals of pixels offset in the upper and lower directions by one pixel is obtained as the interpolated G-signal.
