Abstract

The present invention relates to a calibration system and method including a pixelated display including pixels for projecting an image, an imager positioned to capture the image produced by the pixelated display, and a processor. The processor is configured to determine and measure non-uniformity in the image produced by the pixelated display by repeatedly selecting and illuminating a subset of the pixels in the pixelated display with respective driving currents, controlling the imager to capture the image projected by the subset pixels, determining and storing, for each pixel in the subset, an intensity value produced in response to the respective driving current, and updating, for each pixel in the subset, the respective driving currents based on the determined intensity value and previously stored intensity values corresponding with previously stored driving currents.
