Abstract

Abstract An automatic framing device for photographic use for recording a video signal representing a photographic image on a recording medium by taking the photographic image by a video camera, having control means for detecting edges along X-Y coordinates of the photographic image placed on a table having an X-Y plane and driving the table so that the center of the photographic image is in line with the optical axis of a zoom lens of the video camera, and adjusting the zoom lens so that the entire photographic image is reproduced within a television screen.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 231 words
An automatic framing device for photographic use for recording a video signal representing a sheet bearing photographic image or the like on a recording medium by taking said sheet by photographing means, comprising a table having a horizontal plane positioned beneath said photographing means, movable in directions of an X axis and a Y axis in said horizontal plane with said sheet placed on said horizontal plane, an L-shaped position restricting member disposed on said table for restricting position of said sheet on said table by contacting a corner of said sheet against said L-shaped position restricting member, a first sensor and a second sensor for detecting lengths of sides of said sheet along said X axis and Y axis from a reference point, said reference point being a cross-point of contact lines of said sheet with said L-shaped position restricting member, and a control means for comparing length signals representing lengths of sides of said sheet detected by said first and second sensors, driving a zoom lens of said photographing means so as the entire area of said sheet to be within a viewing frame of said photographing means in dependence on output signal of said first sensor when ##EQU3## or on output signal of said second sensor when ##EQU4## and moving said table so as the optical axis of said zoom lens to be positioned centrally of said sheet.
Claim 2
Dependent Claim 231 words
An automatic framing device for photographic use for recording a video signal representing a sheet bearing photographic image or the like on a recording medium by taking said sheet by photographing means, comprising a table having a horizontal plane positioned beneath said photographing means, movable in directions of an X axis and a Y axis in said horizontal plane with said sheet placed on said horizontal plane, an L-shaped position restricting member disposed on said table for restricting position of said sheet on said table by contacting a corner of said sheet against said L-shaped position restricting member, a first sensor and a second sensor for detecting lengths of sides of said sheet along said X axis and Y axis from a reference point, said reference point being a cross-point of contact lines of said sheet with said L-shaped position restricting member, and a control means for comparing length signals representing lengths of sides of said sheet detected by said first and second sensors, driving a zoom lens of said photographing means so as the entire area of said sheet to be within a viewing frame of said photographing means in dependence on output signal of said first sensor when ##EQU3## or on output signal of said second sensor when ##EQU4## and moving said table so as the optical axis of said zoom lens to be positioned centrally of said sheet.
Claim 3
Dependent Claim 16 words
An automatic framing device for photographic use as claimed in claim 1, wherein b/a is 3/4.
Claim 4
Dependent Claim 32 words
An automatic framing device for photographic use as claimed in claim 2, wherein said photographing means is a video camera operatively connected to a television monitor and to a video recording device.
