摘要： A method and system for performing spatial temporal multiplexing using a multi-threshold mask. A mask generator (404) outputs a threshold value for each pixel of a display. The mask generator typically creates a blue noise mask for a given pixel array that is replicated over the face of the entire display. The blue noise mask generator (404) typically is implemented as a memory lookup table. An index generator (402) provides an offset into the memory lookup table that allows the table to be shifted from time to time. The output of the blue noise mask generator (404), which may be the threshold value itself or a signal representing which threshold is being used, is an input to a selective inverter (406). The selective inverter (406) provides the option of inverting the blue noise mask. To reduce artifacts, the mask is periodically shifted and/or inverted. The value from the mask generator (404), whether inverted or not, is compared to the LSBs of the input data word to yield the fractional bit values. The data adjust block (410) receives the LSBs of the input data word and apportions the intensity between the various fractional bits and perhaps one or more binary bit. Allocating the data between the fractional and binary bits allows the gradual feathering in of each more significant bit as the image intensity word increases.

摘要： A display system includes a light source 110 and a spatial light modulator 122 located to receive light from the light source. The spatial light modulator (e.g., a DMD) includes a number of independently controllable elements that are activated for a period of time to display light of a desired brightness. A light sensor 136 is located to determine a characteristic of light from the light source 110. A control circuit 126 is coupled to the spatial light modulator 122 and controls the period of time that the independently controllable elements are activated. This period of time is based at least in part by an input received from the light sensor 136.

摘要： A method and system providing boundary dispersion to pixel values displayed on a binary spatial light modulator to reduce temporal contouring artifacts. Pixel code values are offset from a nominal value when displayed on the SLM to disperse a large bit transition for a pulse width modulation (PWM) system. The offset value varies as a function of the pixel digital code, the pixel spatial location on the screen, and pixel temporal location in time. The set of offsets applied to pixels is varied over a repeating sequence of 2 displayed frames.

摘要： 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).

摘要： A system and method for reducing pulse width modulation contouring artifacts. Each input intensity value is translated to at least one non-binary bit pattern for display. Many of the input intensity values are translated to at least two alternate non-binary bit patterns. The alternate codes are used to smooth the transition between intensity codes as major bits are turned on. The smoothing occurs by the gradual transition from codes that do not use the major bit to codes that do use the major bit. Typically the alternate codes are selected based on the location of the pixel in a spatial pattern (100) and the alternate codes are spatially alternated from one pixel (102) to the next (104). Other embodiments temporally alternate the codes from one period—typically a frame period—to the next. Still other embodiments alternate the codes both spatially and temporally.
