Abstract

Abstract There is provided an image pickup device having a high resolution used for a movie camera, a still camera (shutter) camera) and the like. This image pickup divice includes a photo-to-photo conversion element (PPCE) comprising at least a photoconductive layer member, a dielectric mirror and an optical modulation layer member disposed between two transparent electrodes, a first image formation elements for forming an optical image of an object on said photo-to-photo conversion element, a second image formation elements for scanning, in two direction substantially perpendicular to each other, optical image information corresponding to said optical image of said object using a light from said photo-to-photo conversion element to read it out, and for changing the light beam reading out said optical image information to a scanning light beam, a canning locus of which on a plane becomes a line, and recording medium transportation mechanism for allowing a recording surface of a recording medium to be located on said plane where a linear image of said optical information is formed, and for continuously moving said recording medium in a direction having an angle with respect to said line of the scanning locus.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 160 words
An image pickup device comprising: a photo-to-photo conversion element comprising at least a photoconductive layer member, a dielectric mirror, and an optical modulation layer member which are disposed between two transparent electrodes; a first image formation means for forming an optical image of an object on said photo-to-photo conversion element; a second image formation means for scanning, in two directions substantially perpendicular to each other, optical image information corresponding to said optical image of said object using a light beam and for forming the light beam reading out said optical image information into a scanning light beam, a scanning locus of which on a plane becomes a line; and recording medium transportation means for allowing a recording surface of a recording medium to be located on said plane where a linear image of said optical information is formed, and for continuously moving said recording medium in a direction having an angle with respect to said line of the scanning locus.
Claim 2
Dependent Claim 160 words
An image pickup device comprising: a photo-to-photo conversion element comprising at least a photoconductive layer member, a dielectric mirror, and an optical modulation layer member which are disposed between two transparent electrodes; a first image formation means for forming an optical image of an object on said photo-to-photo conversion element; a second image formation means for scanning, in two directions substantially perpendicular to each other, optical image information corresponding to said optical image of said object using a light beam and for forming the light beam reading out said optical image information into a scanning light beam, a scanning locus of which on a plane becomes a line; and recording medium transportation means for allowing a recording surface of a recording medium to be located on said plane where a linear image of said optical information is formed, and for continuously moving said recording medium in a direction having an angle with respect to said line of the scanning locus.
Claim 3
Dependent Claim 39 words
An image pickup device as set forth in claim 1, wherein said transportation means comprises a mechanism for continuously transporting said recording medium in the direction substantially perpendicular to said line of the scanning locus at a constant speed.
Claim 4
Dependent Claim 25 words
An image pickup device as set forth in claim 1, wherein said second image formation means comprises coherent light irradiation means for forming a hologram.
