Image Sensor and color modes
The Colour 8k sensor is composed of
two pairs of sensitive lines.
The Colour version has been completed with
RGB colour Filter and disposed as detailed
beside.
Each pair of lines use the same Analog to
Digital Column converter (ADC Column). An
appropriate (embedded) Time delay in the
exposure between each line this allows to
combine two successive exposures in order to
double the sensitivity of a single line.
This Time Delay Exposure is used only in the
Full Definition Enhanced mode (See Below).
2.2.1
True Colour Enhanced Mode (TCE)
10µm pixels (R,G,B)
Twice less pixels than B/W
Requires x3/2 the data flow of B&W
High Sensitivity True Color mode:
Equivalent to 6 x Pixels of 5µm (with
their respective colour filters).
“Full Exposure control” not needed in
TC as the TDI is not active (only
binning). The Exposure time can be
control as for a single line mode.
