Abstract
Abstract In a color photoelectric conversion apparatus in which a plurality of semiconductor image sensors each having a plurality of light-receiving windows are arrayed, and a plurality of light-receiving windows in a main scanning direction constitute one color light-receiving element, the last light-receiving window or at least two light-receiving windows including the last light-receiving window of a first semiconductor image sensor of adjacent semiconductor image sensors, and the first light-receiving window or at least two light-receiving windows including the first light-receiving window of the next semiconductor image sensor constitute one color light-receiving element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A multi-chip color image sensor in which a plurality of semiconductor image sensors each having a plurality of light-receiving windows are arrayed, and a plurality of light-receiving windows in a main scanning direction constitute one color light-receiving element, wherein a last light-receiving window or at least two light-receiving windows including the last light-receiving window of a first semiconductor image sensor of adjacent semiconductor image sensors, and a first light-receiving window or at least two light-receiving windows including the first light-receiving window of the next semiconductor image sensor constitute one color light-receiving element.
Claim 2
Dependent Claim
92 words
A multi-chip color image sensor in which a plurality of semiconductor image sensors each having a plurality of light-receiving windows are arrayed, and a plurality of light-receiving windows in a main scanning direction constitute one color light-receiving element, wherein a last light-receiving window or at least two light-receiving windows including the last light-receiving window of a first semiconductor image sensor of adjacent semiconductor image sensors, and a first light-receiving window or at least two light-receiving windows including the first light-receiving window of the next semiconductor image sensor constitute one color light-receiving element.
Claim 3
Dependent Claim
91 words
A sensor according to claim 1, wherein of the plurality of arrayed semiconductor image sensors, output signals corresponding to a first light-receiving window or at least two light-receiving windows including the first light-receiving window of the first semiconductor image sensor, which window or windows does or do not constitute a color light-receiving element, and a last light-receiving window or at least two light-receiving windows including the last light-receiving window of a last semiconductor image sensor, which window or windows does or do not constitute a color light-receiving element, are not used.
Claim 4
Dependent Claim
59 words
A sensor according to claim 1, wherein color filters are arranged on the light-receiving windows of each of the plurality of semiconductor image sensors, some or all of the color filters are sequentially arranged on the light-receiving windows color by color in accordance with a combination of colors selected from red, green, and blue, or cyan, magenta, and yellow.
Claim 5
Dependent Claim
103 words
A color image sensor comprising: (a) a plurality of sensors arranged in a line in a predetermined direction to be separated at predetermined intervals; (b) a plurality of light-receiving windows arranged at a predetermined pitch in the predetermined direction on each of said plurality of sensors; and (c) a plurality of color filters arranged on said plurality of light-receiving windows, a repetition order of said color filters being constant, wherein the repetition order of said color filters on each said sensor individually is the same as the repetition order of said plurality color filters as a whole extending over said plurality of sensors.
Claim 6
Dependent Claim
103 words
A color image sensor comprising: (a) a plurality of sensors arranged in a line in a predetermined direction to be separated at predetermined intervals; (b) a plurality of light-receiving windows arranged at a predetermined pitch in the predetermined direction on each of said plurality of sensors; and (c) a plurality of color filters arranged on said plurality of light-receiving windows, a repetition order of said color filters being constant, wherein the repetition order of said color filters on each said sensor individually is the same as the repetition order of said plurality color filters as a whole extending over said plurality of sensors.
