Functional Description

Data bus
Start of frame line format
The start of frame line contains the contents of the first 16 serial interface registers rather than any
video data. This information immediately follows the line code at the beginning of the line. The code
07
It takes 32 pixel clock periods to output these 16 serial interface register values. The remaining pixel
periods of the video portion of the line are padded out using 07
are also padded with 07
the value from register 0 is output.
Following the escape sequence and line code at the end of active video, a frame count is output.
Active video line format
All video data is contained on active video lines. The pixel data appears as a continuous stream of
bytes within the active lines.
Black line format
The black lines contain information from the sensor black lines (held in zero exposure). This
information may be used by certain co-processors.
Dark line format
The dark lines contain information from the sensor dark lines (shielded from light by metal). The
information from these lines is used by the sensor to calculate a dark average offset value which is
then applied to the video data to ensure a known ‘black’ level for image data.
Blank line format
To reduce the frame rate it is possible to extend the frame length by adding blank data lines. These
contain no video or black line data. In default VGA mode there are no blank lines.
End of frame line format
The end of frame line sole purpose is to indicate the end of a frame, it contains no video data.
