Abstract
The utility model discloses a photosensitive film twill raster. The photosensitive film twill raster comprises a twill lenticular raster (1) and a photosensitive film printing paper (2) which mutually fit. A digial parallax image is projected by a stereo exposure machine onto the photosensitive film twill raster at a certain angle, under the action of the light focusing effect of the twill lenticular raster, a set of parallel fine lines are exposed on the photosensitive film printing paper, by changing incident angles, other parallax images are sequentially exposed, and a stereo photograph which can be seen through naked eyes is formed after film developing. Compared with a photosensitive film ruled raster, the photosensitive film twill raster is advantaged in three aspects: firstly, sharpness of the stereo photograph can be improved, and sawtooth feeling is reduced; secondly, problems of net collision and flickering during exposure of the digital image projected to the raster are solved; and thirdly, an observation vision angle of the stereo photograph is widened, and the watch comfort level is improved. Compared with a paint method, the photosensitive film twill raster has the superhigh stereo sharpness and further solves the problem of dizzy feeling caused by fitting mismatching of the raster and the image.
Description
Affiliated technical field:

Twill column mirror grating (1) is divided into film grating and hard sheet gration, by whole grating material, by certain inclination angle, is cut and forms.The thickness of film grating is no more than 0.2mm, and pitch, between 150～400LPI, can equally enter washer to printing paper and process, stereoscopic sensation a little less than, be applicable to small pieces width stereoscopic photograph.The thickness of hard sheet gration generally surpasses 0.3mm, and pitch, between 30～100LPI, can not bend, can only be in water tank type washer development treatment, stereoscopic sensation is stronger, equal-amplitude surface stereoscopic photograph in being applicable to, and its breadth is mainly limited to can exposure region area and the size of water tank type film processor.In addition, hard sheet gration except can once push or injection mo(u)lding, can also be bonded by cylindrical lens grating film material (3) and transparent plate (4), transparent plate (4) can be glass, PS plate etc., has suitable focusing thickness.
Photosensitive coating film printing paper (2) at least should comprise filmbase (11), sense red beds (10), green layer (9), the blue layer of sense (8), infiltration reflection horizon (7).Sheet base can adopt thickness to be no more than the polyester flake of 0.1mm, sense red beds contains cyan colour coupler, green layer contains magenta colour coupler, the blue layer of sense contains yellow colour coupler, infiltration reflection horizon (7) can adopt titanium dioxide, its effect be allow development, float and determine liquid and can infiltrate photographic layer, and there is higher light reflectance.Different from common printing paper, exposure light, from the incident of slide basic unit, is processed liquid and is infiltrated from infiltration reflection horizon.
The sheet base of the focussing plane of twill column mirror grating (1) and photosensitive coating film printing paper (2) is bonded together, forms photosensitive coating film Slant grating.Adopt this technique, only need to produce photosensitive coating film printing paper, just can be applied on the grating of all size through simple darkroom adhesion technique, very flexible.
The scope of the inclination angle [theta] of grating grid is at 10 °～40 °, and too small angle is unfavorable for eliminating moir Lou Lou patterns and flicker, and excessive angle is unfavorable for stereo display, and the scope that conventionally can further dwindle inclination angle [theta] is 20 °～30 °.Best angle is relevant with grating pitch with the pixel size of three-dimensional exposure machine projection, changes θ, observes projected image from the grating back side, when moir Lou Lou patterns disappearance or close can not distinguishing, is best angle.
Portraiture photography industry has a large amount of demands to high-quality stereoscopic photograph, when the grid stroke direction of personage's outline and stereoscopic photograph is roughly the same, there will be " sawtooth " sense, if adopt the hard sheet gration performance that line number is slightly low particularly evident, therefore, adopt Slant grating can avoid in a large number this " sawtooth " sense.Photosensitive coating film Slant grating provided herein, compared with prior art, has three significant advantages, first, can improve stereoscopic sensation, the sharpness of stereoscopic photograph, reduces sawtooth sense; What secondly, solved that digital picture projects to column mirror grating exposure hits net and light and shade flicker problem; The 3rd, widen the observation visual angle of stereoscopic photograph, improve and watch comfort level.With the output intent such as air brushing than, there is the sharpness of superelevation, also solved the problem of feeling dizzy that grating, picture laminating mismatch are brought simultaneously.
