3. Operating Modes
3.1 Video Timing
The video format mode on power-up is QSIF 30fps by default, although a 25fps mode can also be selected, see serial
register[17], bit 6. The number of active video lines in each mode is the same (124) for both the QSIF modes. The slower frame
rate (25 fps) is implemented by simply extending the line period from 203 pixel periods to 301 pixel periods.
Table 2 details the setup for each of the video timing modes.

3.2 Pixel Array
The physical pixel array is 168 x 124 pixels. The pixel size is 12.0 µm by 12.0 µm. The output video image size is 164 x 124
pixels. The border pixels from the array are used as a shield from edge effects.
Figure 3 shows how the 164 x 124 is aligned within the bigger 168 x 124 pixel array. Image read-out is flexible. By default the
sensor read out is configured to be horizontally ‘non-shuffled’ non-interlaced raster scan. The horizontally ‘shuffled’ raster scan
order differs from a conventional raster in that the pixels of individual rows are re-ordered, with the even pixels within a row read-
out first, followed by the odd pixels. This ‘shuffled’ read-out within a line, groups pixels of the same colour (according to the Bayer
pattern - Figure 1) together, reducing cross talk between the colour channels. The horizontal shuffle option would normally only
be selected with the colour sensor variant, VV6301.
