5.4.1 Data Structure for a Y (Mono 8) or an
R, G or B (Raw 8) Component
The data output for a Y (mono 8) component or an R, G or B (raw 8) component is 8 bit data of
the “unsigned char” type. The range of data values for a Y mono component and the
corresponding indicated signal levels are shown below.
5.4.2 Data Structure for a U or a V Component
The data output for a U or a V component is 8 bit data of the “straight binary” type. The range of
data values for a U or a V component and the corresponding indicated signal levels are shown
below.
The signal level of a U component or a V component can range from -128 to +127 (decimal).
Notice that the data values have been arranged to represent the full signal level range.
