Abstract
An imaging device is provided with an imaging sensor having a rectangular imaging surface, an image-forming optical system for forming an image onto the imaging surface, and a prism disposed between the image-forming optical system and the imaging sensor for bending an optical path. A mask, having a rectangular opening, limits light that is to be incident on the imaging sensor. The aspect ratio (long side/short side) of the mask rectangular opening of the mask is larger than that of the rectangular imaging surface, and the peripheral light quantity difference between the short and long sides on the rectangular imaging surface is smaller than in the case of these two aspect ratios being equal to each other.
