STV0984
2 MegaPixel SMIA Profile 2 Mobile Imaging Processor
DATA BRIEF
– Sensor interface: 2x CCP2.0(2) serial
receivers (csi class 2 receivers)
Features
■ Supports 2 SMIA profile 2 compliant sensors
– Host interface: CCP1.01. serial transmitter
(csi class 0 transmitter), ITU, PI
mutually exclusive up to 2 Megapixel
(1600x1200) resolution.(1)
– Control interface: I²C
■ Enhanced video processor
■ Flash gun control (high power LED mode and
– Noise/defect filtering, color reconstruction,
sharpness enhancement and radial
corrections
white LED mode)
Description
– Statistic processor for exposure and white
balance and autofocus control
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.
– 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 up-
scale capability to 4x
Applications
■ SMIA output formats: JPEG, YUV4:2:2,
■ Mobile phone
■ PDA
YUV420, RGB888, RGB565, RGB444
■ 4:2:0 JPEG compression with programmable
quantization matrix and target file size
■ Wireless security camera
■ JPEG operations up to 30 fps at UXGA
