Embodiment 1

[0062] A polarizing plate (first polarizing plate) and a phase difference plate are attached to the front end portion of the lens of the camera for TV photography in order from the lens side. As the first polarizing plate, a commercially available polarizing plate (the adhesive was removed from Nitto Denko Co., Ltd. product name "SEG1425GU") was used. The retardation plate is to use a commercially available polycarbonate resin retardation film (manufactured by Kaneka Corporation, product name "TR430", in-plane retardation Re (590) = 430nm) with the mutual slow axis parallel and laminated two sheets. become. The in-plane retardation Re(590) of the retardation plate (laminate) was 860 nm, and Re(450) / Re(550) was 1.1. Set the direction of the absorption axis of the polarizer of the first polarizer to the vertical direction, and set the direction of the slow axis of the phase difference plate to a direction of 45° counterclockwise relative to the vertical direction when viewed fr...

Embodiment 2

[0065] The retardation plate is made of commercially available cycloolefin resin retardation film (manufactured by Kaneka Corporation, product name "UTZ-FILM#270", in-plane retardation Re (590) = 270nm) with the mutual slow axis parallel and stacked 5 A sheet was prepared, and a photographic image and a composite image were obtained in the same manner as in Example 1 except that. The in-plane retardation Re(590) of the retardation plate (laminate) was 1350 nm, and Re(450) / Re(550) was 1.0.

[0066] The photographic image and the composite image were evaluated with the naked eye. As a result, the background of the photographic image was darker green than that of Example 1, and the composite image was more vivid and beautiful than that of Example 1.

Abstract

Provided is a set of optical films usable for an image generation system that can eliminate the need for a large shooting space, a large number of and various kinds of lighting apparatuses, or the know-how of lighting engineers, suppress undesired coloring on a subject, facilitate a response to a color change of the subject, use light from the rear, and finally achieve an overall image with excellent quality. The set of optical films according to the present invention is used for the image generation system. The set of optical films comprises: a first polarizing plate; a second polarizing plate; and a phase difference plate. The image generation system comprises: an imaging device, the first polarizing plate, the subject, and the second polarizing plate disposed in this order; and the phase difference plate is disposed between the first polarizing plate and the second polarizing plate. The phase difference plate is configured such that the color of the second polarizing plate recognized by the imaging device satisfies a* <=-10.

Description

technical field [0001] The present invention relates to assemblies of optical films for use in image generating systems. Background technique [0002] Image synthesis technology is widely used in video fields such as television broadcasting and movies. Image synthesis is typically carried out in accordance with the following procedures: use a camera or the like to take photos of subjects such as people in the foreground (hereinafter referred to as subjects) with a background made of blue, green, and other fabrics of complementary colors to the skin color; use chroma key The device detects the above-mentioned photographic image signals such as blue and selects the subject image area, and makes the information of the background image into a key signal to make it transparent, and then combines the subject image with other background images. [0003] Conventional image synthesis technology has the following problems: (i) In order to uniformize the blue color of the back screen,...
