navigation, search   CMOS or CCD sensor video capture quality
can be enhance with image processing, like auto white balance
(AWB) and auto exposure algorithms (AE):   Some camera sensors
don't include auto white balance and/or auto exposure
processing, so RidgeRun offers a library with AE and AWB
algorithms called librraew. This library was initially developed
for the DM365 platform. The DM365 video processing front end
(VPFE) has an H3A module designed to support control loops for
auto focus, auto white balance and auto exposure by collecting
statistics about the imaging/video data. There are two blocks in
this module:    • Auto focus engine   • Auto exposure and auto
white balance engine     • Accumulation of the sum of squared
pixels per color.   • Minimum and maximum pixels values in each
window per color.  The AE/AWB engine c
