STV0674

Tri-mode CMOS digital camera co-processor

®

Description

The STV0674 is a flexible, scalable digital camera

co-processor for use with the range of CMOS

imaging sensor products from STMicroelectronics.

The same chipset can be used for a wide range of

digital imaging products with unique features and

price/performance points.

The STV0674 is designed for use with CIF

(352x288) or VGA (640x480) ST CMOS image

sensors and provides full exposure control, color

processing and mode control for these sensors.

The STV0674 can be used to implement any of the

following products:

Low cost USB Webcam Camera - a two-chip

solution providing up to 30 frames per second VGA

simultaneous video and audio capture.

Dual-Mode Camera - USB webcam and CIF or

VGA digital still camera in a single product.

Tri-Mode Camera - USB webcam and digital still

camera with the addition of a ‘camcorder’ mode to

allow simultaneous video and audio capture directly

to external memory for later upload to the PC.

Features

s VGA or CIF CMOS sensor support

s Flexible external memory options

q

SDRAM for lower cost, (8 or 16 bit)

q

FLASH for non volatile storage (Data + Code)

q

Smartmedia Card for removable data storage

q

EEPROM for code storage

s Record simultaneous video and audio direct

to memory while untethered

s Drivers for PC operating systems Win98,

WinME, Win2K and WIn XP.
