Abstract
An image processing device includes: a first interpolation unit that performs interpolation using pixel information of pixels having a color same as a color of a pixel of attention and present around the pixel of attention; a second interpolation unit that interpolates color information lost in the pixel of attention using color information of the pixels around the pixel of attention; a combining unit that combines outputs of the first and second interpolation units; a first filter that includes a first filter frequency characteristic and detects a first image of a first region; a second filter that includes a second filter frequency characteristic and detects a second image of a second region; and a combination-ratio generating unit that generates a value for determining a combination ratio of the outputs of the first and second interpolation units in the combining unit.
