STV0986
5 Megapixel mobile imaging processor
Data Brief
Features
Supports 2 mutually exclusive SMIA profile 2 compliant sensors of up to 5 Megapixel resolution(a) Interfaces - Sensor interface: 2 x SMIA CCP Class 2(b) receivers (640Mbit/s) - Host interface: SMIA CCP Class 1(b) transmitter (416Mbit/s) or ITU (8-bit CCIR interface, up to 80MHz) - Control interface: IC (400kHz) Enhanced video processor - Noise and defect filtering, color reconstruction, sharpness enhancement, 4-channel lens shading correction and barrel distortion correction - Statistic processor for automatic exposure, automatic white balance and auto-focus control - General purpose input/outputs (GPIOs) for controlling external actuators 2 video pipes for full frame-rate concurrent viewfinder and video/still capture. 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 4:2:0 JPEG compression with programmable quantization matrix and target file size
JPEG operations up to 30 fps at 2 Megapixel resolution, up to 20 fps at 3 Megapixel resolution, and up to 12.5 fps at 5 Megapixel resolution Interleaved video modes (concurrent viewfinder and video/still capture) - `Alternate frame' mode up to 15 fps - `Single frame' mode up to 30 fps Image rotation/mirroring/flip support for viewfinder (up to CIF) Independent host interface transmitter clock, generated by an embedded PLL - frequency selectable by host Synchronised flash gun control with red-eye reduction (pre-flash and main-flash strobes for high-power LED or Xenon strobe control) Enhanced multi-zone auto-focus (supporting up to 9 zones with programmable weighting)

Description
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.
