Abstract

Intra-frame high dynamic range (HDR) infrared imaging is accomplished in a 1280 x 720 format, 8 um pixel pitch digital readout integrated circuit (DROIC) by spatially combining neighboring pixels with different integration times to obtain HDR pixels. Intra-frame HDR imaging achieves the same level of dynamic range improvement as traditional inter-frame HDR imaging without compromising temporal resolution. Proximal interpolation to retain the spatial resolution of the HDR infrared frame, tone mapping to effectively display HDR infrared content on limited dynamic range displays, and pseudo-coloring to better visualize HDR infrared imagery are discussed.
