Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
36 words
A photo-electric converter comprising: parallel connection means for parallelly connecting a plurality of photo-electric conversion elements; and combined signal read means for reading out a combined signal from the plurality of parallelly connected photo-electric conversion elements.
Claim 2
Dependent Claim
29 words
A photo-electric converter according to Claim 1 further comprising individual signal read means for reading out an independent individual signal of each of the plurality of photo-electric conversion elements.
Claim 3
Dependent Claim
34 words
An image information processing apparatus having the photo-electric converter according to Claim 1, comprising photometry means connected to said combined signal read means, and distance measurement means connected to said individual signal read means.
Claim 4
Dependent Claim
17 words
An image information processing apparatus comprising the photo-electric converter according to Claim 1 and a light source.
Claim 5
Dependent Claim
28 words
An image information processing apparatus comprising the photo-electric converter according to Claim 1 and means for recording said image signal from the photo-electric converter to a recording medium.
Claim 6
Dependent Claim
14 words

Claim 7
Dependent Claim
14 words
A photo-electric converter according to Claim 6 wherein said transistors amplify photo-electrically converted signals.
Claim 8
Dependent Claim
26 words
A photo-electric converter according to Claim 1 wherein said parallel connection means produces an average output of the signals of the plurality of photo-electric conversion elements.
Claim 9
Dependent Claim
71 words
Photoelectric conversion apparatus comprising a plurality of photoelectric conversion elements, connection means for selectively connecting or disconnecting the elements or their outputs, and control means for selectively controlling the connection means to connect during a storage or a read-out operation thereby to provide a combined output from two or more of the elements and for selectively controlling the connection means to disconnect thereby to permit separate outputs from separate said elements.
Claim 10
Independent Claim
56 words
A method of operating a photoelectric conversion apparatus comprising a plurality of photoelectric conversion elements and connection means for selectively connecting or disconnecting the elements or their outputs, the method comprising connecting two or more elements or their outputs during or after accumulation so as to provide a combined output from the two or more elements.
