Abstract
Abstract A solid-state image storage device employing a recording system which permits easy reproduction of an excellent image even if a relatively low-grade recording medium and recording and reproducing device are used. The solid-state image storage device is provided with a photoelectric converter having a plurality of non-destructive readout image sensor cells arranged in a predetermined form; a scanner for scanning the photoelectric converter to read out image information of the image sensor cells; and a recorder having a recording medium for recording the image information read out by the scanner. An image formed on the photoelectric converter is read out by the scanner a plurality of times and each image information thus read out is recorded at one position on the recording medium of the recorder.

Claim 3
Dependent Claim
25 words
A solid-state image storage device according to claim 1 wherein the non-destructive readout image sensor cells are photoelectric conversion elements, each having a hook structure.
Claim 4
Dependent Claim
105 words
A solid-state image storage device according to claim 1 wherein the scanner includes a word line driver for sequentially selecting picture element trains, each train consisting of a plurality of the image sensor cells arranged in a column direction on the photoelectric converter; a plurality of bit lines for taking out the outputs from the image sensor cells of each picture element trains selected by the word line driver; a plurality of analog switches for connecting the bit lines to an image signal readout line; and a synchronizing signal generator for performing ON-OFF control of the analog switches and control of the word line driver.
Claim 5
Dependent Claim
71 words
A solid-state image storage device according to claim 1 wherein the recorder records the image information of the same image on the recording medium in such a manner that image information read out first is recorded in an area on a track followed by image information read out subsequently being recorded in those areas of the same track contiguous to the area having recorded therein the first read out image information.
Claim 6
Dependent Claim
57 words
A solid-state image storage device according to claim 1 wherein the scanner scans the image sensor cells of the photoelectric converter at intervals using a predetermined algorithm to read out image information of all the image sensor cells at a plurality of times, and the recorder records the image information at different positions on the recording medium.
Claim 7
Dependent Claim
25 words
A solid-state image storage device according to claim 2, wherein said recorder is a magnetic medium recorder, said recording medium comprising a magnetic recording medium.
Claim 8
Dependent Claim
119 words
