Abstract
Abstract A color sensor array in which vertical output lines correspond to different colors. The reading order and the reading periods for each color are adjusted in one of two ways. Separate vertical shift registers are provided for each color and the separate vertical shift registers are selectively enabled. Alternatively all color are simultaneously read but the color lines are selectively coupled to one output line.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A solid state image pickup device comprising a plurality of photoelectric conversion elements arranged in a matrix form, vertical switches provided for said photoelectric conversion elements, horizontal switches provided for said photoelectric conversion elements, a vertical shift register comprising shift register units, for controlling said horizontal switches, coupled to at least one of said vertical shift register and said horizontal shift register, for altering the sequence of outputs from the shift register units to thereby selectively determine the order of energizing said photoelectric conversion elements, whereby the sequence of the output signals from said photoelectric conversion elements can be selectively varied by altering the output sequence from said shift register units.
Claim 2
Dependent Claim
111 words
A solid state image pickup device comprising a plurality of photoelectric conversion elements arranged in a matrix form, vertical switches provided for said photoelectric conversion elements, horizontal switches provided for said photoelectric conversion elements, a vertical shift register comprising shift register units, for controlling said horizontal switches, coupled to at least one of said vertical shift register and said horizontal shift register, for altering the sequence of outputs from the shift register units to thereby selectively determine the order of energizing said photoelectric conversion elements, whereby the sequence of the output signals from said photoelectric conversion elements can be selectively varied by altering the output sequence from said shift register units.
Claim 3
Dependent Claim
71 words
The device as defined in claim 1 wherein said vertical shift register comprises a plurality of groups of shift register units, each group of shift register units being connected to a selected output terminal of said altering means, so that in response to signals applied to said selected output terminals, said groups of shift register units are selectively caused to provide output signals to activate selected ones of said vertical switches.
Claim 4
Dependent Claim
37 words
The device as defined in claim 2, wherein control inputs of all vertical switches in a line of said photoelectric conversion elements are controlled by a separate unit of one of said groups of shift register units.
Claim 5
Dependent Claim
19 words
The device as defined in claim 3, further comprising a matrix of color filters overlying said photoelectric conversion elements.
Claim 6
Dependent Claim
42 words
The device as defined in claim 1 wherein said means for altering further comprises means for selectively controlling duration of the outputs from said shift register units to thereby selectively control the duration of the output signals from said photoelectric conversion elements.
Claim 7
Dependent Claim
33 words
The device as defined in claim 5, wherein said selecting means at any time selects only one of said output signals from said photoelectric conversion elements to pass to a predetermined output line.
Claim 8
Dependent Claim
19 words
The device as defined in claim 6, further comprising a matrix of color filters overlying said photoelectric conversion elements.
