FUNCTIONAL DESCRIPTION
8.1
Black offset preprocessing
The CCD signal contains additional pixels outside the
active window, which are used to measure the reference
black level. These pixels are located in the optical black
window, whose position can be set through the serial
interface. The optical black level can be adjusted by the
microcontroller in orderto proceedrapidly. In thiscase,the
microcontroller directly adjusts the analog preprocessing
clamp included in the TDA8786 or TDA8784 and takes
advantage of the full code range. Otherwise, the black
level is fixed by settings that are downloaded through the
serial interface.

For each pixel value, this block (see Fig.3) generates the
three components: the luminance signal Y and the two
colour signals C

memories are required for this function. This block also
provides vertical contour and white clip information.
