6.10.1.4.1 Auto Focus (AF) Engine
The following features are supported by the Auto Focus (AF) Engine.
•
•
•

•
Peak Mode in a Paxel (a Paxel is defined as a two dimensional block of pixels).
Accumulate the maximum Focus Value of each line in a Paxel
Accumulation/Sum Mode (instead of Peak mode).
Accumulate Focus Value in a Paxel.
Up to 36 Paxels in the horizontal direction and up to 128 Paxels in the vertical direction.
Programmable width and height for the Paxel. All paxels in the frame will be of same size.
Programmable red, green, and blue position within a 2x2 matrix.
Separate horizontal start for paxel and filtering.
Programmable vertical line increments within a paxel.
Parallel IIR filters configured in a dual-biquad configuration with individual coefficients (2 filters with 11
coefficients each). The filters are intended to compute the sharpness/peaks in the frame to focus on.
6.10.1.4.2 Auto Exposure (AE) and Auto White Balance (AWB) Engine
The following features are supported by the Auto Exposure (AE) and Auto White Balance (AWB) Engine.
•
•
•
•
•
Accumulate clipped pixels along with all non-saturated pixels.
Up to 36 horizontal windows.
Up to 128 vertical windows.
Programmable width and height for the windows. All windows in the frame will be of same size.
Separate vertical start coordinate and height for a black row of paxels that is different than the
remaining color paxels.
•
•
Programmable Horizontal Sampling Points in a window.
Programmable Vertical Sampling Points in a window.
