– Noise/defect filtering, color reconstruction,
sharpness enhancement and radial
corrections
CCI
– Statistic processor for exposure and white
balance and autofocus control
– GPIOs and ADC to control external
actuators
– Host interface: CCP1.0(a) serial transmitter
(csi class 0 transmitter), ITU, PI
– Control interface: I²C
■ Flash gun control (high power LED mode and
■ 2 video pipes for full frame rate concurrent
viewfinder and video/still capture. Single shot
(e.g. flashgun) thumbnail generation
white LED mode)
Applications
– Gamma correction programmable for both
CRT and LCD displays. Color correction
matrix
■ Mobile phone
■ PDA
– Digital zoom: smooth downscale capability
(independent X/Y characteristics) and up-
scale capability to 4x
■ Wireless security camera
Description
■ SMIA output formats: JPEG, YUV4:2:2,
YUV420, RGB888, RGB565, RGB444
The STV0984 is a new generation, ultra low
power Megapixel digital image processor
■ 4:2:0 JPEG compression with programmable
quantization matrix and target file size
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.
■ JPEG operations up to 30 fps
■ 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(b) serial
receivers (csi class 2 receivers)
