Abstract:
1. An imaging apparatus in which a subject image is formed by an imaging optical system on an imaging plane wherein a plurality of pixels are two-dimensionally arranged, and a light receptor element for photoelectric transformation at each pixel is positioned, characterized in that: said imaging optical system comprises a molded optical element fabricated through a fabrication process in which a periodic streak is produced on an optical surface, wherein: when high-brightness subject light whose brightness value exceeds the saturation sensitivity of said light receptor element enters said imaging optical system, a nonessential light image resulting from said streak on said optical surface based on said high-brightness subject light is formed on said imaging plane and in an area of a subject image from said high-brightness subject light at the time when said optical plane is supposed to be free of said streak.
