Abstract: The present invention relates to a means for creating a visual illusion of directional movement based on stationary motion elements referred to as “motion pixels.” In various embodiments, methods for using the directional illusion are provided, such as 1) the measurement and/or assessment of visual performance in active and virtual reality environments, 2) the measurement and/or assessment of acuity, in conjunction with eye trackers so as to measure visual performance in nonverbal or potentially malingering observers, 3) the enhancement of advertising and marketing by drawing attention to a desired symbol, and 4) the enhancement of images so as to produce the appearance of motion in otherwise stationary images.

Abstract: Embodiments described herein disclose a color measurement device and method for use with cameras or other imaging devices. The color measurement device may be configured to determine many different colors via a commonly owned device. Embodiments utilize sinusoidal grayscale rings to determine an exact color match of an unknown color, even if there is perspective distortion of an obtained image.

Abstract: The present disclosure describes systems, methods, and apparatus for reducing the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 620 nm, and a visual spectral response of the human eye. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response. Methods of use and methods of manufacturing optical filters are also described.

Abstract: An optical film includes a polymeric bandstop filter reflecting a band of blue light in a range from 440 nm to 480 nm a polymeric bandstop filter reflecting a band of blue light in a range from 440 nm to 480 nm and transmitting greater than 50% of blue light at a wavelength of 10 nm longer than a long wavelength band edge and at a wavelength of 10 nm shorter than a short wavelength band edge.

Abstract: A viewing device for a stereo projection system, having a first and a second viewing window, each having an optically filtering filter layer system, wherein each viewing window has a filter spectrum in the visual spectral range having a plurality of pass bands that are separated from each other by blocking regions, and wherein each pass band of the filter spectrum of the first viewing window is covered by an associated blocking region of the filter spectrum of the second viewing window. Each filter layer system can be designed as an absorption filter layer system having a plurality of substances absorbing in differing spectral ranges, wherein at least one of the absorbing substances is a cyanine dye in the supramolecular configuration of a J-aggregate.

Abstract: A system and method for generating a projected image signal encoded with position information. The temporal pixel-location data is hidden within visible light signal used for regular image projection. This enables the user to utilize one or multiple ring-shaped light receivers to implement touch or multi-touch functions on a regular image content generated using light from the same projector. The temporal light signal generated by the projector is sliced into multiple temporal segments. The segments include segments of two different types. A segment of the first type is used for carrying a temporal position signal of each pixel in the projector signal. On the other hand, a segment of the second type is used to adjust the color of each pixel. With the color adjustment segment projected to each image pixel, a meaningful visible content of a regular image can be displayed despite the presence of the position-encoded signal segments.

Abstract: A lighting control device includes: an irradiation light generation unit that receives an irradiation light signal; coating correcting means for correcting the irradiation light signal so that an irradiation target object can be coated with irradiation light; and an irradiation light projection unit that projects the irradiation light by using the corrected irradiation light signal. The irradiation light includes coating light that coats the irradiation target object, and background light that becomes a background of the irradiation target object. The lighting control device includes: a first coating correction unit that corrects the irradiation light signal so as to cut an outline of the coating light in conformity with a shape of the irradiation target object; and a second coating correction unit that corrects the outline of the coating light in response to a positional relationship between an origin position of the irradiation target object and the irradiation light projection unit.

Abstract: A method for processing an anaglyph image to produce an enhanced image is described. The method includes receiving an anaglyph image; determining first and second feature locations from the first and second digital image channels and producing feature descriptions of the feature locations; and using the feature descriptions to find feature point correspondences between the first and second feature locations of the first and second digital image channels. The method further includes determining a warping function for the second digital image channel based on the feature point correspondences; producing an enhanced second digital image channel by applying the warping function to the second digital image channel; and producing an enhanced image from the first digital image channel and the enhanced second digital image channel.

Abstract: Methods are disclosed for supporting stereo 3D video in computing devices. A computing device can receive stereo 3D video data employing a YUV color space and chroma subsampling, and can generate anaglyph video data therefrom. The anaglyph video data can be generated by unpacking the stereo 3D video data to left and right views and combining the left and right views into a single view via matrix transformation. The combining uses transform matrices that correspond to a video pipeline configuration. The transform matrix coefficients can depend on characteristics of the video pipeline components. Modified transform matrix coefficients can be used in response to changes in the video pipeline configuration. Video encoded in stereo 3D video data can be selected to be displayed in stereo 3D, anaglyph or monoscopic form, depending on user input and/or characteristics of video pipeline components.
