Abstract
An imaging apparatus includes an optical imaging system that converges light from an object; an imaging device that includes a plurality of pixels, receives the converged light, and converts the received light to an electric signal; a filter unit that is disposed between the optical imaging system and the imaging device and includes a plurality of color filters having different light transmission rate characteristics; and a transmission data compressing circuit that codes the electric signal. An overall light transmission rate characteristic of the filter unit differs randomly in different pixels of the imaging device, and the transmission data compressing circuit weights and codes the electric signal of each of the pixels by using a reciprocal of a proportion of the overall light transmission rate characteristic of the filter unit corresponding to each of the plurality of pixels of the imaging device relative to a wavelength characteristic common among the pixels.
