Problems solved by technology

[0003] Two factors have affected the further development and application of lenticular stereoscopic images. First, the stereoscopic depth of field should not be too large, otherwise the double image caused by the fission of the front and back images will be unbearable, and the image is not clear and thorough, which is not conducive to expressing the wide scene with large depth ; Second, moiré patterns are prone to appear, which brings dizziness, which causes discomfort to some viewers, and hinders the wide application of three-dimensional pictures in commerce.
[0004] The main reason is that in the current various color digital image output methods, the separation of pixels is not high, and most of the pixels are still interpenetrated. This is contradictory to the requirement of separating the horizontal pixels of the sampling image. The fission of the image will inevitably be caused by the effect of the image, which is intuitively manifested in the high-contrast details of the foreground and foreground in the stereo image. In addition, the mismatch of the stereo image caused by the low size accuracy of the output image often brings unbearable dizziness. sense

Embodiment Construction

[0029] Make a high-definition three-dimensional picture.

[0030] Prepare a standard 40LPI slit grating with a format of 80cm*60cm and a thickness of 5mm, the grating period p=0.635mm, prepare 12 parallax sequence diagrams, scale each image to 1260*945 size, and then combine the size to 15120* Stereo sampling map of 945. The phototypesetting accuracy of the laser imagesetter is 2400dpi, and the size of each monochromatic grid is 5*20. The entire sample image is gridded by the rectangular aggregation method, and then output to the laser phototypesetting film. Prepare a mixed-color color plate, the width of the R, G, and B three-color lines is 0.2117mm, and the line width of each group is 0.635mm. The mixed color plate can be prepared by spot color printing, which is convenient for mass production and has a low cost; if it is output to the lamp chip by three-color laser exposure, the cost advantage is completely lost. The slit grating, phototypesetting film, and color mixing plat...

Abstract

The present invention discloses a structure of a high definition grating three-dimensional picture and a manufacture method thereof. The three-dimensional picture consists of a grating and a samplingdiagram. The output of the sampling diagram is combined with laser phototypesetting, halftone screen and color mixing techniques. With a laser phototypesetter, the components of RGB three colors are combined after gridding the sampling diagram, and the combined components are outputted to a film so as to be aligned with the subsequent color mixing chromatography to form a color picture which presents a clear and intensive three-dimensional image when being irradiated by a backlight source. The structure of the present invention solves the problems of the three-dimensional picture of scene depth fission, ghost and giddying, thereby greatly improving the definition of the images and effectively improving the watching comfort degree.

Description

Technical Field: [0001] The invention belongs to the field of optical display technology, and relates to a method and structure for making a grating stereo picture. Background technique: [0002] With the maturity of lenticular three-dimensional imaging technology, three-dimensional pictures have gradually gained popularity in industries such as photography, advertising, and decoration due to their freedom of viewing, strong three-dimensional perception and good adaptability. A stereo picture is usually composed of a stereo grating and a sample map. The stereo grating can be a slit or a lenticular grating. The sample picture is a new image re-sampled from a series of stereo parallax images. The characteristics of the sample map are that the details are very rich, the image information is large, and it is generally output by digital laser printing, color photo printing, printing, etc. [0003] Two factors have affected the further development and application of raster stereo images...
