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 method and apparatus for spatially and temporally multiplexing display data. The use of this method results in a bit-depth resolution higher than that achievable by the system given a number of bits of resolution. The method includes the steps of determining the desired perceived resolution (26), establishing the number of bit-planes to be used to achieve that perceived resolution (28), using at least one of those bit-planes for spatial-temporal least significant bit values (STMLSBs) (30), referencing the developed values of the STMLSBs to fractional bit gray code levels (32), developing spatial patterns (34), determining whether the spatial patterns will start in a predetermined sequence or randomly from frame-to-frame (36), loading the data onto the modulator and displaying it (38). The apparatus includes a random number generator (48) and a look up table (50) to enable the choice between random and predetermined spatial patterns, and pattern logic (46), which produces the pattern to be used.

摘要： Methods and apparatus for use with a discrete bit display system such as a DLP® display system for increasing brightness by using secondary light bits (such as spoke bits that are otherwise wasted). The light available from the secondary bits is distributed over the entire input/output dynamic range by determining the maximum possible output and then defining the dynamic output range from zero to that maximum range in response to the full range of the input signals.

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.
