Pixel measurement
For exact measurements within the incoming video
stream, two reference pixel positions can be defined with
ref_row_0, ref_col_0 and ref_row_1, ref_col_1. The
R, G and B components of this pixel are sampled and
available at ref_pixel_red_0/1, ref_pixel_green_0/1 and
ref_pixel_blue_0/1. The reference pixel colour values can
be used for fine tuning the external PLL in frequency and
phase and for colour gain adjustment.
Three submodes are available to output the maximum
value, the minimum value or the mean value at the
dedicated position (see Table 36).
To simplify the measurements, the values can be taken as
asinglesnapshotrepresentingthemomentaryvalueofthe
pixel at the reference position or they can be build up over
several frames, which is activated by programming the
number of frames to bits aa_cycles.
