A UHD 2/3 inch CMOS Imager with Dynamic Pixel Management - An Enabler for New Format Flexibility
The broadcast market currently faces changes that are challenging for imaging solutions, such as the the change from high definition (HD) to ultrahigh-definition (UHD), and the introduction of high dynamic range (HDR). In the phases of change, more flexible solutions are needed. The dynamic pixel management (DPM) technology already available in some frame transfer charged coupled devices (CCDs) offered a unique solution for lossless switching between 4:3/16:9 aspect ratios and between all the different HD formats, including 2.37:1 widescreen. Smaller UHD pixels do not offer the same performance as larger HD pixels, and, until now, CMOS imagers have not allowed the pixel size to be changed. This is a real limitation for anyone who needs to produce in UHD as well as in HD. The new CMOS-based XensiumHAWK imagers with DPMUltra technology offer a solution by providing the ability to select the pixel size for native UHD or native HD to deliver UHD or HD performance with no compromise. This paper explains the background and the development of the new flexible pixel-sized technology.
