The focus point is important and could affect the squal value, the
graph below showing another setup with various z-height. The graph
clearly shows that the squal count is dependent on focus distance.
Note:
This graph is obtained by getting multiple readings over different heights.
Figure 38. Typical mean squal vs. Z (white paper).

Data Type: Eight bit number.
USAGE: SQUAL is a measure of the number of features visible by the sensor in
the current frame. The maximum value is 255. Since small changes in the
current frame can result in changes in SQUAL, variations in SQUAL when
looking at a surface are expected. The graph below shows 250 sequentially
acquired SQUAL values, while a sensor was moved slowly over white paper.
SQUAL is nearly equal to zero, if there is no surface below the sensor.
