Wide Dynamic Range Image Recording Technique Using DMD Camera by STEP Method

Abstract

A wide dynamic range image recording technique using a digital micromirror device (DMD) camera with a spatio-temporal exposure pattern (STEP) method is proposed. By incorporating DMD technology, each pixel in the DMD camera can be recorded at a different exposure time. The wide dynamic range images are reconstructed using the spatial and temporal intensity information simultaneously. Preliminary experimental results showed that the DMD camera can record wider dynamic range images with a minimum reduction in resolution.
