Abstract

PURPOSE: To obtain a given photo output signal without shading by compensating the shading characteristics for the photo sensing section through the adjustment of the light receiving area of the photo sensing video element.
CONSTITUTION: In the photo detecting section of a CCD line sensor, a plurality of photo gate electrodes 11 are arranged in primary dimension the photo detection section of MOS constitution, i.e., the insulation film 12 on one side of the P tye Si substrate 15, for example, and the incident window 61 performing the light shield 10 with Al at the incident light side of the electrode 11 is placed, allowing to introduce the incident light from the window 61. Further, when a positive voltage is applied to the electrode 11, the well 62 is formed in the substrate 13 and charges excited are stored. The photo detection area of each video element of the photo sensing section is adjusted as shown in Fig. A so that the shading characteristics of the photo detection section can be compensated, allowing to obtain a given photo output signal without shading.
