摘要： In display systems employing spatial light modulators, the OFF-state light from OFF-state pixels of the spatial light modulator can be captured and directed back to the pixels of the spatial light modulator so as to recycle the OFF-state light in the display system. Bitplanes derived from the desired image to be produced are calibrated to include the recycled off-state light to properly produce the desired image using the display system.

摘要： In a method embodiment, a method for image processing includes receiving one or more signals indicative of an optical characteristic of one or more respective light beams. A transform is generated based on the received one or more signals. The transform converts a first plurality of image components encoded by a first plurality of colors to a second plurality of image components encoded by a second plurality of colors.

摘要： According to one embodiment of the present invention, a system for encoding an optical spectrum includes a dispersive element, a digital micromirror device (DMD) array, a detector, and a controller. The dispersive element receives light from a source and disperses the light to yield light components of different wavelengths. The digital micromirror device (DMD) array has micromirrors that modulate the light to encode an optical spectrum of the light. The detector detects the light that has been modulated. The controller generates an intensity versus time waveform representing the optical spectrum of the detected light.

摘要： System and method for maintaining perceived hue constancy. A method for displaying an image includes receiving a color vector and associated image data, remapping the color vector to maintain a perceived hue constancy by adjusting a hue component of the color vector in response to a change in a lightness component or a chroma component of the color vector, providing the remapped color vector to a light source for display, and displaying image data associated with the color vector. The use of the constant hue curve ensures that the adjusting of the color vector maintains the perceived hue of the color vector, thereby helping to maintain image quality.

摘要： A system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, a fingerprint sensor, and a sensing circuit. The fingerprint sensor includes an input surface to receive input of a finger skin surface. The sensing circuit is configured to track a pattern of fingerprint ridges of the finger skin surface on the input surface. Execution of programming by a processor configures the system to perform functions to track, via the sensing circuit, the pattern of fingerprint ridges of the finger skin surface on the input surface; generate a fingerprint image having the tracked pattern of fingerprint ridges; extract fingerprint features from the fingerprint image; and authorize the user to utilize the eyewear device based on the extracted fingerprint features.
