Abstract
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.
