Abstract

Abstract (57) A solid state image pickup device comprising a photosensitive picture element unit (5) having a matrix of horizontal and vertical photosensitive picture elements (71) for converting light into electric charges via photoelectric conversion; a horizontal charge coupled unit (72, 76) which transfers the electric charges in the horizontal direction; and a vertical charge coupled unit (72,74) which transfers the electric charges in the vertical direction. Information formed of the picture elements within a specified portion of the photosensitive picture element unit is outputted as picture element output signals in response to external control signals. From the overall image information received on the light receiving unit of the solid-state image pickup device, picture element information within a selected range can be internally processed and output as desired image signals in response to the external control signals.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 129 words
A solid-state image pickup device comprising: photosensitive picture element unit comprising photosensitive picture elements arranged in a matrix in horizontal and vertical directions to convert light containing picture element information into electric charges corresponding to individual picture elements through photoelectric conversion; horizontal charge transfer channel which transfers said electric charges corresponding to individual picture elements in the horizontal direction; and vertical charge transfer channel which transfers said electric charges corresponding to individual picture elements in the vertical direction; at least one of said vertical charge transfer channel and said horizontal charge transfer channel being controlled in response to external signals, so that a part of said electric charges corresponding to individual picture elements in a specified part of said photosensitive picture elements are outputted as picture element output signals
Claim 2
Dependent Claim 129 words
A solid-state image pickup device comprising: photosensitive picture element unit comprising photosensitive picture elements arranged in a matrix in horizontal and vertical directions to convert light containing picture element information into electric charges corresponding to individual picture elements through photoelectric conversion; horizontal charge transfer channel which transfers said electric charges corresponding to individual picture elements in the horizontal direction; and vertical charge transfer channel which transfers said electric charges corresponding to individual picture elements in the vertical direction; at least one of said vertical charge transfer channel and said horizontal charge transfer channel being controlled in response to external signals, so that a part of said electric charges corresponding to individual picture elements in a specified part of said photosensitive picture elements are outputted as picture element output signals
Claim 3
Dependent Claim 32 words
The solid-state image pickup device according to Claim 1, wherein said horizontal charge transfer channel has a plurality of output takeout outlets which are selectively actuated according to said external control signals.
Claim 4
Dependent Claim 49 words
The solid-state image pickup device according to Claim 1, wherein said horizontal charge transfer channel transfers said electric charges bidirectionally in the horizontal direction in response to said external control signals, and/or said vertical charge transfer channel transfers said electric charges bidirectionally in response to said external control signals.
Claim 5
Dependent Claim 36 words
The solid-state image pickup device according to Claim 1, wherein said photosensitive picture element unit has a charge removal channel at a peripheral part of the matrix arranged picture elements for removing picture elements transferred thereto.
Claim 6
Dependent Claim 51 words
The solid-state image pickup device according to Claim 1, wherein said photosensitive picture element unit has a charge carrying picture element horizontal transfer channel which transfers all of said electric charges or a part of said electric charges altogether unidirectionally in the horizontal direction in response to said external control signals.
