An imaging apparatus includes a condenser lens optical system and a solid-state imaging device so that a pencil of incident light rays passing through the condenser lens optical system and then incident on the solid-state imaging device can be converged in a conical shape with a result that an image of the pencil of incident light rays can be formed on one point of a light receiving surface of the solid-state imaging device due to light condensing effect of the condenser lens optical system, and the imaging apparatus further includes a correcting portion which performs image quality correction on a taken image signal outputted from the solid-state imaging device in accordance with set correction quantities; and each of the correction quantities is defined in accordance with an image height direction angle width and an incidence angle as defined herein.
