Patent Images
1. A solid state image sensing apparatus comprising:
- a solid state image sensing means including a plurality of photoelectric elements two-dimensionally disposed in an imaging plane, said photoelectric elements being capable of issuing a signal charge corresponding to the quantity of incident light thereon when the respective photoelectric elements are selected to issue an output;
first selecting means for sequentially selecting respective ones of said photoelectric elements so as to pickup the signal charge from said selected photoelectric elements in sequence in a first operating mode;
second selecting means for selecting a plurality of specified photoelectric elements from said photoelectric elements so as to pickup the signal charge therefrom simultaneously in a second operating mode; and
mode changing means for selectively supplying a mode selection signal to said first and second selecting means so as to carry out the operating mode selection.

Abstract
A solid state image sensor comprises an image sensing matrix comprised of a number of photoelectric elements arranged in a matrix array and a scanning circuit for two-dimensionally scanning the image sensing matrix by scanning signals to extract image signals. Picture element selection circuits are connected to horizontal and vertical lines of the image sensing matrix to pick up the output signals of photoelectric elements as photometric signals.
