摘要： PURPOSE: To accurately cut film at a central position between the front and the rear of a perforation and to facilitate film cutting work by recording a cutting mark as a latent image at the edge part of the center between the front and the rear of each perforation by pre-exposure. CONSTITUTION: The perforations 2 are formed near both upper and lower edges of the photographic film 1. The camera using the film 1 is designed to set an exposing position so that a photographic image plane may be positioned in the middle of upper and lower and right and left perforations 2 and to make an image plane pitch equal to the pitch P1 of the perforation 2. By using this camera, the upper and the lower perforations 2 become the mark of a cut surface. A vertical direction cutting mark 3 is recorded as the latent image at the central position at the central position between the front and the rear of the periphery of the perforation 2 on the upper and the lower edge sides of the film 1. Therefore, the cutting mark 3 appears at the upper and lower edges of the vertical center line of a gap G after developing. The film is cut by aiming at the mark 3.

摘要： PURPOSE:To provide a stable high-resolution and high-definition picture by performing suitable anti-aliasing filtering to a source picture and performing suitable edge enhance even on a screen when compositing one video signal from two video signals or over of CCD imaging devices at different optical positions. CONSTITUTION:The output image signals of CCD imaging devices 101 and 105 are inputted through chrominance signal extraction circuits 102 and 106, matrix circuits 103 and 107 and chrominance signal processing circuits 104 and 108 to a correspondent point extraction circuit 109. The state of overlapping picture elements at one point of a certain object detected by the respective elements 101 and 105 is calculated from the image and outputted by the circuit 109. On the other hand, the image signals of the elements 101 and 105 are inputted to a color extraction circuit 150. The circuit 150 calculates a color difference signal from the difference of the output signals from the elements 101 and 105. That color difference signal passes through a matrix circuit 151, chrominance signal processing circuit 152 and distortion correcting circuit 155, and suitable edge enhance is performed at an edge enhance circuit 153. A two-dimensional video signal is composited from the signals of the circuits 109 and 153 by a compositing circuit 112 and displayed on a display 115.

摘要： PURPOSE:To easily obtain a stereoscopic photograph with two simple cameras by holding two simple cameras in a state where the optical axes of their photographing lenses are separated in parallel in a right-and-left direction and simultaneously actuating shutters. CONSTITUTION:Two simple cameras 11 and 12 are mounted in parallel in a frame 20. The left end of a shutter operating lever 33 is inserted in the square hole 29 of a left side surface plate 25 and a notch 34 is locked on the upper edge of the hole 29, then the right end of the lever 33 is inserted in the recessed part 30 of a right side surface plate 26 and a locking piece 31 is rotated to close the recessed part 30. By respectively operating the film winding knobs 16 of the two cameras 11 and 12, the shutters of the cameras 11 and 12 are charged, and the composition of photographing is decided. By pushing the lever 33 downward, two projections 35 press the corresponding shutter release buttons 15 of the cameras 11 and 12 and a subject is simultaneously photographed by the two cameras 11 and 12.

摘要： PURPOSE: To enable recording a transmission hologram, without entailing the interference from reflected light by reflective lining by using a photopolymerizable compsn. contg. a specific binder. CONSTITUTION: The reflective lining is provided thereon with a photopolymerizable layer. The photopolymerizable layer consists of a binder, at least one liquid ethylenic unsatd. monomers having additive polymerability and a b.p. of >=100 deg.C and a free radical generation system which may be activated by chemical effect radiations. The binder is a thermoplastic polymer binder which is selected from a group, consisting of cellulose ester, polystyrene, styrene copolymer contg. at least about 60% of styrene and poly(methyl methacrylate) and is soluble in solvents. The more preferable binder is cellulose acetate butyrate, polystyrene, poly(methyl methacrylate), 70:30 poly(styrene-methyl methacrylate), etc.

摘要： PURPOSE:To detect depth information in a picture efficiently with high accuracy by picking up plural pictures with different fog from one visual point by one camera. CONSTITUTION:Each fog of plural pictures with different fog obtained by a fog control section 1 and a TV camera 2 is evaluated by a fog evaluation section 4, a depth discrimination section 5 discriminates whether or not a depth of an object area is single from the change and when single, a depth calculation section T calculates the depth, and when not single, a picture division section 6 divides an object area to investigate the depth again and it is repeated till one depth corresponds to the object area to detect the depth in the picture.
