6.10.1.4 Hardware 3A (H3A)
The Hardware 3A (H3A) module provides control loops for Auto Focus, Auto White Balance and Auto
Exposure. There are 2 main components of the H3A module:
•
•
Auto Focus (AF) Engine
Auto Exposure (AE) & Auto White Balance (AWB) Engine
The AF engine extracts and filters the red, green, and blue data from the input image/video data and
provides either the accumulation or peaks of the data in a specified region. The specified region is a two
dimensional block of data and is referred to as a “paxel” for the case of AF.
The AE/AWB Engine accumulates the values and checks for saturated values in a sub sampling of the
video data. In the case of the AE/AWB, the two-dimensional block of data is referred to as a “window”.
The number, dimensions, and starting position of the AF paxels and the AE/AWB windows are separately
programmable.
The H3A register memory mapping is shown in Table 6-33.
