Abstract: 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.

Abstract: An apparatus is provided that includes a laser that produces light at a first wavelength, an optical element that converts the light at the first wavelength received at an input end thereof into light at a second wavelength, and an optical interface proximate the input end of the optical element that directs light at the second wavelength through the optical element toward an output end of the optical element.

Abstract: Methods of reducing contouring in images display by a linear display device, such as a spatial light modulator. The methods operate on a high resolution signal, which represents a stream of pixel values. The per pixel resolution of this signal is greater than the per pixel display resolution, and its less significant bits are treated as an error component. Random values are added to the error component either in conjunction with error diffusion values (FIG. 1) or to provide a dither that is directly proportional to the error (FIG. 4), or to provide a dither that has both spatial and temporal contributions (FIG. 5).

Abstract: A method for operating a scan-line video processor that allows for vertical scaling with no additional memory in a display system and extracts more SVP instructions in vertical down scaling applications. The input and output sync periods of the SVP (16) are controlled such that the SVP (16) produces output lines of interpolated data that is a vertical scaling factor of the input lines. The data is then sent to a memory (24) to correct for centering and time base changes in the interpolated data. Finally, the data is sent to a display device, such as a CRT or a spatial light modulator.
