Sensor geometry
Pixel format (ADU)
C-RED 3 digitizes the signal from the sensor with 14-bits precision. After embedded bias subtraction,
the resulting pixels values may become negative, so the default configuration of the camera is to send
pixel values using 16 bits signed integers. Since firmware 1.3.0, the camera can be configured to send
16 bits unsigned values. This is done by adding an offset after the bias subtraction and forcing any
remaining negative value to 0.
Full frame mode
Pixels are read from left to right and up to down (see Figure 14 and Figure 15) starting from the left top
corner.
