Abstract: PURPOSE:To prevent coloring phenomenon by using a specified polymer for a transparent film having the polymer oriented in a specified direction and exhibiting birefringence, and forming this film between a linearly polarizing plate on one side and a TN crystal layer. CONSTITUTION:A TN liquid crystal layer 4 is sandwiched with two linearly polarizing plates 6, 7 each having a polarizing axis crossing each other at right angles, and a transparent film 7 having a polymer oriented in a specified direction and exhibiting optical birefringence and erasing coloring display phenomenon is inserted between one of the plates 6, 7 and the layer 4. Polycarbonate, a copolymer of tetrafluoroethylene and hexafluoroethylene, or polyfluoroethylene propylene ether is used for the material of this film 7. The rotation angle of this film 7 is controlled so as to maximize the erasion effect of said phenomenon. As a result, the coloring phenomenon remarkably occurring especially in a large- sized cell can be easily erased, an off-grade rate in manufacture can be lowered, further, occurrence of elliptic polarization can be reduced, and contrast can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To eliminate misdetection which is caused by variation in the density in an image processing area, owing to the automatic iris operation of a visual camera by deciding that an image processing area which has density variation in reverse to other two image processing areas is an area that a moving body has entered. SOLUTION: The place of an image processing area 3 in a visual camera video screen is set. A movement decision part 19 is inserted and connected between a projection processing part 17 and a D/A conversion part 18. This movement decision part 19 detects the direction (high luminance/low luminance) of the density variation in each image processing area, at the time of automatic iris operation and decides whether or not a moving body moves. When the image processing area having density change is an area 1 or 2, it is decided that the area having the density changed is the area where the body has moved. If the density has changed in the entice area, it is decided that the body has moved only in the area 1 having density changed, when the direction of the density change is in the relation of the area 1 versus the area 2.
