摘要： Scanning mirror based display system and method. A method comprises sampling a scanned light provided by a scanning mirror, converting the sampled scanned light into an electrical signal, analyzing the electrical signal to determine a position of the scanned light, and controlling the light source or the scanning mirror based on the analyzed electrical signal. The electrical signal based on the sampled scanned light may be used to ensure proper operation of the scanning mirror display system, such as determining failure of the scanning mirror, proper rendering of colors, determining whether the scanned light is following a desired scan path at a desired scan rate, and so forth.

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.

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： A method and apparatus for controlling a lamp. A timer (106) reads a rated safe life value from a memory (102) associated with a lamp in a lamp module (104). The memory (102) in the lamp module (104) contains a series of locations in which the rated safe life of the lamp has been stored, and a series of locations for storing the elapsed on time of the lamp. The timer controller (106) reads the series of locations storing the rated safe life of the lamp and verifies the validity of the values using a series of checksums and comparisons between the various values. The timer controller (106) also reads the series of locations storing the elapsed on time for the lamp and verifies the elapsed on time in a similar manner. If either the rated safe on time or the elapsed on time cannot be verified, the lamp is disabled. If both can be verified, and the lamp is enabled until the elapsed on time equals or exceeds the rated safe life.
