Creating High Bit Depth Grayscale Images

Generating Grayscale Images Generating accurate images with a variety of bit depths is an important requirement for a number of industrial and medical uses for structured light. This note looks at some of the techniques and tradeoffs involved in generating such images on a DMD as well as some of the applications. The ‘black and white’ images captured by early still and motion cameras effectively used a continuous scale to capture light variations by the use of chemistry to lock in the image. Projecting the images used the same approach. Moving to digital technologies meant that the gray levels in…
