X&Y-Subsampling
With subsampling in both X and Y, the sensor skips both rows and columns. There are only 2
schemes possible in this mode: read 1 row/column, skip 1 row/column (monochrome) and read 2
rows/columns, skip 2 rows/columns (color). Below you can find an overview of the settings used for
monochrome and color devices together with some examples for X&Y-subsampling.
