5.4 Image Data Structure
5.4.1 Data Structure for a Y (Mono 8) Component
The data output for a Y (mono 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.
