Abstract
Abstract A solid-state image sensor of a CCD is disclosed, wherein the photodiodes in the photo-sensing part are arranged in regions separated horizontally. A vertical CCD channel is interposed between the photodiodes so that high resolution is achieved by increasing the horizontal resolution without any change of the driving pulse frequency or the charge handling capability.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A solid state image sensor comprising: a horizontal CCD channel, a plurality of vertical CCD channels connected to said horizontal CCD channel for sequential transfer of charges thereto, a plurality of photodiodes arranged between and connected to adjacent vertical CCD channels for producing charges generated by light and transferring said charges to said vertical CCD channels, transfer gates for transferring the charges from said photodiodes to said vertical CCD channels, and output means connected to said horizontal CCD channel for converting and outputting charges sequentially supplied thereto by said horizontal CCD channel, said photodiodes being arranged in two vertical lines of horizontally adjacent photodiodes between two successive vertical CCD channels, and channel stop means between said horizontally adjacent photodiodes for preventing interference therebetween, said transfer gates being arranged to transfer the changes from said horizontally adjacent photodiodes in said two vertical lines in alternation to respective different ones of said two successive vertical CCD channels so that each vertical CCD channel will transfer, in alternation, charges from photodiodes in vertical lines on opposite sides of said vertical CCD channel.
Claim 2
Dependent Claim
179 words
A solid state image sensor comprising: a horizontal CCD channel, a plurality of vertical CCD channels connected to said horizontal CCD channel for sequential transfer of charges thereto, a plurality of photodiodes arranged between and connected to adjacent vertical CCD channels for producing charges generated by light and transferring said charges to said vertical CCD channels, transfer gates for transferring the charges from said photodiodes to said vertical CCD channels, and output means connected to said horizontal CCD channel for converting and outputting charges sequentially supplied thereto by said horizontal CCD channel, said photodiodes being arranged in two vertical lines of horizontally adjacent photodiodes between two successive vertical CCD channels, and channel stop means between said horizontally adjacent photodiodes for preventing interference therebetween, said transfer gates being arranged to transfer the changes from said horizontally adjacent photodiodes in said two vertical lines in alternation to respective different ones of said two successive vertical CCD channels so that each vertical CCD channel will transfer, in alternation, charges from photodiodes in vertical lines on opposite sides of said vertical CCD channel.
Claim 3
Dependent Claim
54 words
The image sensor according to claim 1, wherein the two vertical lines of photodiodes between successive vertical CCD channels respectively represent lines of odd and even photodiodes, each vertical CCD channel being connected to the line of odd photodiodes on one side thereof and the line of even photodiodes on the other side thereof.
Claim 4
Dependent Claim
25 words
The image sensor according to claim 2, wherein the photodiodes in said odd and even lines produce respective distinct output signals differing from one another.
Claim 5
Dependent Claim
32 words
The image sensor according to claim 2, comprising a plurality of unit pixels, each unit pixel being divided by said channel stop means into two said horizontally adjacent odd and even photodiodes.
Claim 6
Dependent Claim
40 words
The image sensor according to claim 4, wherein the odd and even photodiodes of each unit pixel are connected via respective said transfer gates to the different, respective vertical CCD channels between which the odd and even photodiodes are disposed.
Claim 7
Dependent Claim
29 words
The image sensor according to claim 1, wherein said photodiodes in said two lines are isolated whereby horizontal resolution is increased without change of driving frequency and driving capacity.
Claim 8
Dependent Claim
55 words
The image sensor according to claim 2, wherein the transfer gates are operated to feed to each vertical CCD channel combined signals from two photodiodes in successive horizontal rows in an adjacent odd line of photodiodes in alternation with combined signals from two photodiodes in successive horizontal rows in an adjacent even line of photodiodes.
