■ 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 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.
Applications
■ Mobile phone
■ PDA
■ Wireless security camera
