| STV0984 2 MegaPixel SMIA Profile 2 Mobile Imaging Processor DATA BRIEF Features Supports 2 SMIA profile 2 compliant sensors mutually exclusive up to 2 Megapixel (1600x1200) resolution.(1) Enhanced video processor - Noise/defect filtering, color reconstruction, sharpness enhancement and radial corrections - Statistic processor for exposure and white balance and autofocus control - GPIOs and ADC to control 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 downscale capability (independent X/Y characteristics) and upscale capability to 4x SMIA output formats: JPEG, YUV4:2:2, YUV420, RGB888, RGB565, RGB444 4:2:0 JPEG compression with programmable quantization matrix and target file size JPEG operations up to 30 fps at UXGA resolution Interleaved video modes (concurrent still/video + ViewFinder) - `Alternate CCP frame' mode up to 15 fps - `Single CCP frame' mode up to 30 fps CCP transmitter derating capabilities (by 2,3,4,5 and 6) of sensor high speed clock Interfaces - Sensor interface: 2x CCP2.0(2) serial receivers (csi class 2 receivers) - Host interface: CCP1.01. serial transmitter (csi class 0 transmitter), ITU, PI - Control interface: IC Flash gun control (high power LED mode and white LED mode) Description The STV0984 is a new generation, ultra low power Megapixel digital image processor designed to fit into mobile applications. STV0984 comes with support for 2 SMIA sensor heads and programmable intelligent General Purpose IOs engine to control, through dedicated firmware, external actuators such as flashgun, white led and autofocus solution. STV0984 provides internal buffering capability along with a versatile clock manager to accommodate different data rates between input sensors and host interface.
