Overview
The STV0974 is a mobile imaging digital signal processor which, when used with VS6552 CMOS
color VGA image sensor from STMicroelectronics, performs all the required data processing to
deliver good quality Viewfinder, still and live color images. The STV0974 performs high quality color
processing on images, achieving JPEG compression if requested and transfers them to a
baseband through one of the available interfaces.
Data is transferred from sensor to STV0974 through Low Electromagnetic Interference (EMI)
interface, using the sensor data transfer protocol over LVDS.
Data is transferred from STV0974 to Baseband
Viewfinder mode
When connected to microprocessor interface or video output interface, the STV0974 can process
Viewfinder image up to 30 frame/s.
Still features
When requested by the baseband, the STV0974 captures bayer data from the sensor. Data is then
color processed, down-scaled and/or compressed and sent through video output or microprocessor
interface. In still mode, the first image produced has a guaranteed good exposure and color
balance for single shot capture.
Live features
When connected to microprocessor interface or video output interface, the STV0974 can process
live video up to 30 frame/s and eventually proceed to down-scaling and compression with on-chip
Motion JPEG. Live mode is intended for capture of video sequences.

through the video output interface. In video mode, the processor streams video data in a format
which closely follows the data format specified in the ITU-R656 standard.
through the microprocessor Interface. In microprocessor mode, the video data is stored in a
small FIFO before is it pulled out of the asynchronous microprocessor interface by the host
system (with DMA support).
