Abstract
A solid state image sensing device comprises a great number of light receiving elements arrayed in rows and columns, a plurality of vertical CCD registers respectively coupled to columns of the light receiving elements for vertically transferring signal charges sensed by the light receiving elements, a horizontal CCD register for horizontally transferring the signal charges transferred from the vertical CCD register, an adder section for adding together signal charges obtained from a predetermined number of light receiving elements arrayed in columns and rows to form one added signal charge and for obtaining a plurality of added signal charges for all the light receiving elements in each of fields, and a field switcher for introducing signal charges obtained from an array of light receiving elements with at least one element shifted from the previous field to the adder section in each field.
