Abstract

Abstract An image pickup apparatus comprising: a charge storage member being movable; a photo-charge conversion unit comprising a photoconductive layer member having a transparent electrode, an electrode, and means for applying an electric field between said transparent electrode and said electrode, said photo-charge conversion unit opposing said charge storage member; and means for focussing an optical image of an object through said transparent electrode onto an image focussing surface of said photo-charge conversion unit via a taking lens, and for forming an electric charge image corresponding to said optical image of the object on said charge storage member. The image pickup apparatus may further comprises reading means for reading said electric charge image corresponding to said optical image and generating an electrical signal according to said electric charge image by opposing said charge storage member.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 96 words
An image pickup apparatus comprising: a movable charge storage member; a photo-charge conversion unit comprising a photoconductive layer member having a transparent electrode, an electrode, and means for applying an electric field between said transparent electrode and said electrode, said photo-charge conversion unit opposing said charge storage member; and means for focussing an optical image of an object through said transparent electrode onto an image focussing surface of said photo-charge conversion unit via a taking lens, and for forming an electric charge image corresponding to said optical image of the object on said charge storage member.
Claim 2
Dependent Claim 96 words
An image pickup apparatus comprising: a movable charge storage member; a photo-charge conversion unit comprising a photoconductive layer member having a transparent electrode, an electrode, and means for applying an electric field between said transparent electrode and said electrode, said photo-charge conversion unit opposing said charge storage member; and means for focussing an optical image of an object through said transparent electrode onto an image focussing surface of said photo-charge conversion unit via a taking lens, and for forming an electric charge image corresponding to said optical image of the object on said charge storage member.
Claim 3
Dependent Claim 42 words
An image pickup apparatus according to claim 1 further comprising; means for displacing said charge storage member with respect to said photo-charge conversion unit, said photoconductive layer and said electrode of which are arranged on opposing sides of said charge storage member.
Claim 4
Dependent Claim 40 words
An image pickup apparatus according to claim 1 further comprising; reading means for reading said electric charge image corresponding to said optical image and generating an electrical signal according to said electric charge image by opposing said charge storage member.
Claim 5
Dependent Claim 51 words
An image pickup apparatus according to claim 3 further comprising; moving means for moving said charge storage member from said photo-charge conversion unit to said reading means so that said electric charge image formed by said focussing means is transported to said reading means and is converted into said electrical signal.
