DESCRIPTION
The STV068 4 is a on e-ch ip cam era pr ocesso r for
UXGA CMOS digital still cameras. ST supplies
complete reference designs including the sensor
and co-processor chipset, firmware and software
drivers. The STV0684 uses a small BGA package
(12 mm x 12 mm) ideal for the design of very small
digital cameras. The STV0684 relies on ST unique
and highl y pe rformin g vi deo pr ocess or algo rithm s
that include, for example, the newly improved and
patented NO RA (Noise Reducti on Algorit hm) and
anti-vignetting algorithms.
APPLICATIONS
■Digital still cameras
■Solid state video camera recorders
■Embedded cameras
