Single shot (e.g. flashgun) thumbnail generation – Gamma correction programmable for both CRT and LCD displays – Color correction matrix – Digital zoom: Smooth 16X downscale capability with up-scale capability to 4X ■ Output formats: JPEG, YUV4:2:2, YUV4:2:0, Planar YUV4:2:0 (up to CIF), RGB888, RGB565, RGB444 The STV0986 is an ultra low power megapixel digital image processor designed to fit into mobile applications. The STV0986 contains advanced image correction, noise reduction techniques and a smooth digital zoom facility, resulting in exceptional image quality in today’s multimegapixel images. The STV0986 supports 2 SMIA sensors, flashgun (LED or Xenon), autofocus and programmable general purpose IOs for additional external actuators. The internal buffer and versatile clock manager within the STV0986 accommodates a wide range of data-rates between the sensors, the STV0986 and the host. ■ 4:2:0 JPEG compression with programmable quantization matrix and target file size Applications a.
