Imaging apparatus, image quality correction method of imaging apparatus, interchangeable lens and imaging apparatus body

摘要

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.

1. An imaging apparatus comprising 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, wherein:
the imaging apparatus further comprises 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, the image height direction angle width serving as an angle width between two light rays obtained when a peripheral wall surface of the conical shape of the pencil of light rays intersects with a plane which passes through the center of the light receiving surface of the solid-state imaging device and which is perpendicular to the light receiving surface, the incidence angle serving as an angle between a center line bisecting the image height direction angle width and a normal line of the light receiving surface.
