The brightest and lowest pixel search determines the position of the brightest pixels and the lowest pixels in a predefined
area. Therefore, the area is scanned from the upper left to the lower right corner. The pixel value and the position values
are readable. Four submodes are available to search independently for RGB minimum and maximum values
(see Table 35).
