Manipulation of RGB data

It is possible to modify the encapsulation of the RGB data in a number of ways:

●

swap the location of the RED and BLUE data

●

reverse the bit order of the individual color channel data

●

reverse the order of the data bytes themselves

Dithering

An optional dithering function can be enabled for each RGB output mode to reduce the

appearance of contours produced by RGB data truncation. This is enabled through the

DitherControl register.

Bayer 8-bit

The ITU protocol allows the encapsulation of various data formats over the link. The

following data formats are also proposed encapsulated in ITU601-656 protocol:

●

RAW 8-bit bayer

●

Truncated from 10-bit

●

DPCM encoded from 10-bit

This is done as described in

Figure 10. In this output mode the output data per pixel is a

single byte. Therefore the output PCLK and data rate is halved.

It is possible to reverse the overall bit order of the individual bayer pixels through a register

programming.

Note:

False synchronization codes are avoided in the LSByte by adding or subtracting a value of

one, dependent on detection of a 0 code or 255 code respectively.
