A system for creating the perception of visual depth in scenery comprising lateral movements. A polarizing projection filter 21 controls the plane of polarization of projected light. The plane of polarization is changed by changing the orientation of the polarizing projection filter. An observer wears special viewing glasses 22 with polarizing filters when viewing scenery illuminated by the polarizing projection filter. The plane of polarization of the polarizing viewing filter for the right eye 23 is rotated 45 degrees clockwise from horizontal. The plane of polarization of the polarizing viewing filter for the left eye 24 is rotated 45 degrees counterclockwise from horizontal. When the polarizing projection filter is rotated clockwise from horizontal the scenery appears brighter to an observer's right eye than to the observer's left eye. Objects moving laterally 42 from right to left from the observer's perspective appear closer to the observer 43. Objects moving from left to right appear farther away from the observer. When the polarizing projection filter is rotated counterclockwise from horizontal the scenery appears brighter to an observer's left eye than to the observer's right eye. Objects moving from right to left from the observer's perspective appear farther away from the observer. Objects moving from left to right appear closer to the observer. In the first and second embodiment of the invention, the scenery comprises polarized imagery projected on a viewing screen. In the third embodiment, the scenery comprises live scenes illuminated by polarized light. The scenery can be viewed in full color. The dead eye effect can be avoided by periodically changing the plane of polarization of the polarizing projection filter.

The present invention relates to a noncontact printing method for applying indicia, such as insignia or stripes, on at least one subsurface layer of a transparent or translucent cover golf ball, e.g. the core, or one or more intermediate layers. The indicia may be visible in ambient light or are only visible when exposed to specific non-ambient light wavelengths, e.g. ultraviolet wavelengths. Advantageously, this method of noncontact printing on subsurface golf ball layers substantially improves the durability of indicia because such indicia are protected from direct abrasion and club impacts by the cover. Moreover, unlike pad printing, noncontact printing forms indicia that are not susceptible to ink degradation because the indicia are solid markings created by very small discrete dots. In one embodiment, both the cover and the intermediate layer(s) may be transparent or translucent and thusly decorated to achieve previously unattainable image depth effects.

Stereoscopic glasses and a display apparatus including the same, which can reduce a user's eyestrain, are provided. The display apparatus includes: a signal processor which processes a three-dimensional (3D) video signal to have a predetermined depth effect; a display unit which displays a 3D image based on the video signal processed by the signal processor; and a controller which controls the signal processor to process a first area determined viewed by a user and a second area that is not determined to be viewed by the user, of the 3D image displayed by the display unit, such that the first area is different in level of a depth effect than the second area. Accordingly, a user's eyestrain is remarkably reduced to thereby increase convenience.

The invention discloses a real time field depth analogy method based on fuzzy partition of a graphics processor. The real time field depth analogy method based on the fuzzy partition of the graphics processor comprises the following steps of (1) converting a to-be-processed image into a file format which can be processed by a graphics processing unit (GPU), (2) processing specific information of the image, (3) carrying out partition blur processing to the image according to the specific information of the image, and deciding that the image adopts different fuzzy radius in different areas according to the specific information, and thus imitating a filed depth effect. Due to the facts that parallelism and programmable capacity of the GPU are fully used, a scene is saved as a texture in render, and a large amount of algebraic operation is transferred from a central processing unit (CPU) to the GPU, the real time field depth analogy method based on the fuzzy partition of the graphics processor not only releases the CPU, but also reduces amount of communication between the CPU and the GPU, and greatly improves imitation speed of the filed depth. Due to the fact that a partition fuzzy algorithm is directly used for processing an original image, a step of fusion of a traditional algorithm fuzzy image and the original image is saved, and accuracy of filed depth imitation is further improved. The image is clear and exquisite, close to a field depth effect picture which is shot by an actual camera, and the real time field depth analogy method based on the partition blur of the graphics processor is applicable to a virtual reality system.

The invention discloses a method for correcting image depth effect which is used for correcting an original image which is obtained from a positron emission tomography by a filtered back projection rebuilding algorithm. In the method, probability distribution data used for image distribution rebuilding at each point within the visual range of a detector of the positron emission tomography is beforehand obtained; then the probability distribution data is processed by the filtered back projection rebuilding algorithm; the depth effect image removal is carried out on the probability distribution data in order of from an outermost ring to an innermost ring; and removed part is transformed into a corresponding exact image to compensate the original image, so as to finish the correction of the depth effect. According to the invention, original software kernel is not required to be amended at all, the correction of DOI effect can be finished just by the superaddition based on the original software, and the invention has flexible operation and also saves time.

The invention relates to a three-dimensional printing method and a decorative plate and a lamp box manufactured through the method. The three-dimensional printing method includes the steps that printing is carried out on a sheet material with a concave-convex surface by means of printing ink capable of being hardened through ultraviolet rays or electron beams, so that the concave-convex appearance of the surface of the sheet after printing is maintained, the printing resolution is 5 times to 20 times of concave-convex density, and the decorative plate with a visual three-dimensional field depth effect is generated. When the sheet material with the concave-convex surface is a transparent lens material, the high-contrast decorative plate or the lamp box can be formed due to the combination of the transparent lens material and a reflective sheet material or a backlight source.
