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.
