STV0986
5 Megapixel mobile imaging processor
Data Brief
■ JPEG operations up to 30 fps at 2 Megapixel
Features
resolution, up to 20 fps at 3 Megapixel
■ Supports 2 mutually exclusive SMIA profile 2
resolution, and up to 12.5 fps at 5 Megapixel
resolution
compliant sensors of up to 5 Megapixel
resolution(a)
■ Interleaved video modes
(concurrent viewfinder and video/still capture)
■ Interfaces
– Sensor interface: 2 x SMIA CCP Class 2(b)
receivers (640Mbit/s)
– ‘Alternate frame’ mode up to 15 fps
– ‘Single frame’ mode up to 30 fps
– Host interface: SMIA CCP Class 1(b)
transmitter (416Mbit/s) or ITU (8-bit CCIR
interface, up to 80MHz)
■ Image rotation/mirroring/flip support for
viewfinder (up to CIF)
■ Independent host interface transmitter clock,
generated by an embedded PLL - frequency
selectable by host
– Control interface: I²C (400kHz)
■ Enhanced video processor
– Noise and defect filtering, color
reconstruction, sharpness enhancement,
4-channel lens shading correction and
barrel distortion correction
■ 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
– Statistic processor for automatic exposure,
automatic white balance and auto-focus
control
up to 9 zones with programmable weighting)
Description
– General purpose input/outputs (GPIOs) for
controlling external actuators
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 multi-
megapixel images. The STV0986 supports 2
SMIA sensors, flashgun (LED or Xenon), auto-
focus 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.
■ 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
Applications
■ Mobile phone
■ PDA
