PURPOSE:To improve the shading phenomenon at four corners of an image screen dimmed by a photodetecting lens to be corrected by a method wherein pixel lenses focussing corresponding to the positions of pixels are provided per respective pixels of solid image sensing element. CONSTITUTION:The title spoiled image sensing device is provided with a photodetecting lens 1, a solid image sensing element 2 converting input light image 7 detected by said lens 1 into electric signal and a signal processing circuit 3 converting signal from the solid image sensing element 2 into electric signal for television camera. Pixel lenses 14a, 14b focussing corresponding to the positions of pixels 15 per respective pixels 15 of the solid image sensing element 2 in such a solid image pick-up device. For example, the curvature of respective pixel lenses 14a, 14b as convex focussing lenses shall be increased from the central pixel of photodetecting surface 6 of solid image sensing element 2 to the peripheral pixels. Through these procedures, the decreases in incoming light quantity due to unvavorable transmittivity at the peripheral parts of photodetecting lens 1 can be corrected to make even images as far as four corners of an image screen. |
