Effect of DLP projector white channel on perceptual gamut

چکیده
Rodney L. Heckaman Mark D. Fairchild Abstract — The effect of white-channel enhancement as implemented in the Texas Instrument DLPTM digital projector technology is evaluated theoretically using both the CIELAB and the CIECAM02 color appearance models and experimentally through psychophysical testing using real images. Both theory and test results confirm a compression of perceptual gamut in both chroma and colorfulness as a result of the added white channel. Hence, while this technology is ideal for viewing graphics and text under ambient conference-room conditions where lightness contrast is important, it is necessarily less than ideal for viewing images or in home-theater environments where color is important.

متن کاملExpanding Display Color Gamut Beyond the Spectrum Locus
Digital video and display media are at a “sweet spot” of growth with brighter and more colorful digital projectors and displays available seemingly every day. Much more is possible in achieving brighter and more vibrant colors, colors that may even transcend our typical experience in terms of dynamic range and an expanded gamut in the perceptual sense. If the full capabilities of these technolo...
متن کاملCharacterization and use of a digital light projector for vision research
For creating stimuli in the laboratory, digital light projection (DLP) technology has the potential to overcome the low output luminance, lack of pixel independence, and limited chromaticity gamut of the cathode ray tube (CRT). We built a DLP-based stimulator for projecting patterns on the in vitro primate retina. The DLP produces high light levels and has good contrast. Spatial performance was...
متن کامل2 16 shades of gray : high bit - depth projection using light intensity control
Projectors create grayscale images by outputting a series of bitplanes or binary images within a short time period. While this technique works well for projecting low bit-depth (8-bit) images, it becomes infeasible for high bit-depth (say, 16-bit) projection — a capability that is increasingly desirable in many applications including cinemas and gaming. Existing designs for high bit-depth proje...
متن کاملSpatially uniform colors for projectors and tiled displays
Alain Pagani Didier Stricker Abstract — A major issue when setting up multi-projector tiled displays is the spatial non-uniformity of the color throughout the display’s area. Indeed, the chromatic properties do not only vary between two different projectors, but also between different spatial locations inside the displaying area of one single projector. A new method for calibrating the colors o...
