An imaging apparatus includes a light receiving device array having light receiving devices, a light transmissive filter including plural types of band-shape light transmissive sections arranged in sequence to form a light transmissive section pattern, and an arithmetic processing unit, wherein the arithmetic processing unit includes a first parameter generating unit configured to generate a first parameter indicative of a displacement of the light transmissive section pattern relative to the light receiving device array in response to a position of one of the light receiving devices, a second parameter generating unit configured to generate second parameters in response to the first parameter generated by the first parameter generating unit, and an image generating unit configured to produce output images in response to image signals output from the light receiving devices and the second parameters generated by the second parameter generating unit.
