Description of the data path
The following drawing illustrates the AUTOFNC_AOI settings in greater detail.
The algorithm is based on the assumption that the R-G-B component sums of the
samples shall be equal, i.e., it assumes that the mean of the sampled grid pixels
is to be monochrome.
Visualization of the AUTOFNC_AOI is carried out with the help of the graphics
overlay (see: block diagram) function of the camera. This area is highlighted
when the Show work area bit is set high.
Manual gain
As shown in:
• Figure 55: Block diagram of AFE (Source: Analog Devices) on page 91
• Figure 56: Signal path of MT9V022 (Guppy F-036 with CMOS sensor) on
page 92
• Figure 57: Signal path of MT9P031 (Guppy F-503 with CMOS sensor) on
page 92
... all cameras are equipped with a gain setting, allowing the gain to be manu-
ally adjusted on the fly by means of a simple command register write.
Figure 60: AUTOFNC_AOI positioning
Note The algorithm will try to create an uncolored image when look-
ing at an area that is completely colored with auto white bal-
ance ON.
