摘要： A method and system for displaying fractional bit data in order to increase the bit depth of a PWM display without requiring the use of an excessive number of bit planes. One embodiment of the present invention combines the outputs of two random number generators (702) with the outputs of a row counter (704) and column counter (706) to yield row and column indexes into two 32×32 cell blue noise masks. The row and column indexes select a blue noise mask threshold for a given pixel. The threshold from the first blue noise mask (708) is applied to a comparator (710) where it is compared to the fractional bit portion of the pixel data. A first blue noise bit, BN(1), is generated based on this comparison. Typically, BN(1) is a “1” when the fractional portion of the pixel data exceeds the threshold value from the mask. The same threshold data is also processed by inverter (712) to produce the threshold that would be shored in an inverted form of Mask A. Inverter (712) prevents the circuitry from having to store four separate blue noise masks. The output of the inverter (712) is also compared to the fractional pixel data to produce a second blue noise bit, BN(2). In the same manner, the second blue noise mask (714) is used to generate two additional blue noise bits. The four blue noise bits are then used alternately in the quad-frame display of FIG. 5 with the integer portion of the pixel data.

摘要： A DMD display system includes an inverse gamma look-up-table (50) for converting raster scanned, gamma corrected video data of 8 bits to 12 bits inverse gamma data with 8 most significant bits (msb) and 4 least significant bits (lsb). The 8 msb are coupled to the micromirror of the DMD display (10) and the four lsb are delayed and halved such that one half of the lsb is added to the next pixel in the horizontal scan and one-half of the lsb is added to the next vertical pixel one line length delayed.

In an embodiment the additional segment comprises a mixed-transmission level region that partially blocks some of the green and red wavelengths. In another embodiment, an additional segment comprises a notch filter that allows shorter and longer wavelengths to pass, but blocks at least some of the intermediate wavelengths. In other embodiments, other segments, such as a white segment, a yellow segment, a cyan segment, a magenta segment, shades thereof, combinations thereof, and/or the like may be added.

摘要： The present disclosure relates to systems and processes for automatically adjusting the white point of displayed images to account for changes in ambient light. In one embodiment, a display system includes a display device having sensors for recording the red (R), green (G) and blue (B) values for ambient light and measuring the intensity of such light. The sensors feed these values into a processor, which calculates R, G, B gain values to be applied to the video input R, G, B values. In this manner, the display device can account for changes in ambient light to adjust the perceived white point accordingly. Related methods for automatically adjusting the white point of a perceived image are also described.

摘要： Disclosed herein are visual display systems and methods capable of having shifted bit-weights in neutral density filtering (NDF) applications. In one embodiment, a method (200) of displaying an image comprises transmitting light through an optical filter (17) comprising at least one high transmissivity portion configured to output light at an initial intensity, and at least one low transmissivity portion configured to output light at a lower intensity than the initial intensity, where the initial intensity and lower intensity output light illuminates a spatial light modulator (14). The method also includes providing a plurality of data bits (non-ND) from a predetermined number of data bits (B0-B7), where each of the plurality comprises a pulse-width longer than a load-time for operating the spatial light modulator (14). In this embodiment, the method further includes providing at least one data bit (ND) from the predetermined number of data bits, where the at least one data bit comprises an initial pulse-width less than the load-time and comprises an adjusted pulse-width greater than the load-time. Then, the method further comprises operating selected portions of the spatial light modulator (14) in coordination with the initial intensity and lower intensity output light using the pulse-widths of one or more of the plurality of data bits (non-ND) and the adjusted pulse-width of the at least one data bit (ND).
