    5.3.4 Camera link output port LQ-401CL handles R, G, B and NIR channels. The output ports for 8-bit and 10-bit are different. The following drawings show the default settings for the Camera Link Video Output Select (Command OS1 to OS6). Camera Link output can be configured by command OS.

  • Page 15: Bit Allocation Of The Output Video

    1000 Fig.9 Signals flow The LQ-401CL uses four high-performance CMOS line scan image sensors mounted on a prism block. During exposure, the incoming light is converted to electrons (electric charge) in the photodiodes (active pixels). The transfer gate controls the transfer of charge from photodiodes to the shift register.
  • Page 16 (the inverse of line rate). This also allows a fixed exposure time, independent of the line rate. In the LQ-401CL the exposure time can be set individually for all four channels.
