Video processor functions
STV0676 provides a master clock SCLK to the camera module. Each 10-bit pixel value
generated by the sensor is transmitted across the 5 wire databus SDATA[4:0] as a pair of
sequential 5-bit nibbles, most significant nibble first. Codes representing the start and end
frames and the start and end of lines are embedded within the video data stream to allow
the video processor to synchronise with the video data stream.
The video processing engine performs the following functions on incoming data:
●
●
●
●
●
The 2-wire sensor serial interface (SSDA and SSCL) provides control of sensor
configuration.
The MSBit SDATA5 of the databus is unused in the current application but it will support
future sensors where a 12bit ADC architecture may be used.
full colour restoration at each pixel site from Bayer-patterned input data,
matrixing/gain on each colour channel for colour purity,
peaking for image clarity,
gamma correction,
colour space conversion from raw RGB to YCbCr[4:2:2].
