STV0684
3.1 Video processor (VP)
The VP is the result of STMicroelectronics extensive know-how and hard work around the colour
science for CMOS sensor. The VP block fulfills many functions related to colour reconstruction from
a bayer filter, colour matrixing and sharpening, real-time and programmable defect pixel correction,
AGC, AWB, Anti flicker and Gamma correction, scaling from the sensor to the required video and
LCD panel resolution. This new video processor benefits from STMicroelectronics latest algorithms
development such as the patented Noise Reduction Algorithm and anti-vignetting that ensures the
highest quality standard.
The VP combines hardware and firmware. The main block controller is powered by a 8051 E WARP
microcontroller, with RAM based firmware for the highest level of flexibility.
