High Definition, High Dynamic Range Color Camera

A program to develop a high definition, high dynamic range color camera employing pixel-level sensitivity control and advanced integration time control is proposed. The proposed High Definition, High Dynamic Range (HD2) color camera builds upon Surface Optics"real-time multi-spectral and hyperspectral imaging activities, including the DuoChrome SWIR/MWIR imager, and the Multi-band Identification and Discrimination Imaging Spectroradiometer (MIDIS). Employing both on-chip sensitivity control and off-chip integration time control, the camera is capable of up to 200 dB of intrascene dynamic range; this dynamic range is available throughout the five megapixel color imagery. Under the Phase I effort, this capability will be proven. Continuing work under Phase II will integrate the prototype sensor into a submarine periscope. The proposed effort represents an extension of Surface Optics"19 years experience in multispectral and hyperspectral imager design, and in ultra-high dynamic range imagers. By building on Surface Optics Corporation"s experience in imaging system development, sensor development, and algorithm development, the proposed program will produce a new ultra-high dynamic range high-definition color imager.
