Appendix B: Sensitivity Mode

Sensitivity Mode and Pixel Readout

The camera has the option to operate in either high sensitivity or low sensitivity mode or in tall pixel

mode.

When in high sensitivity mode, the camera uses both line scan sensors and its responsivity increases

accordingly. When in low sensitivity mode, the camera uses the bottom sensor. When operating in tall

pixel mode, the camera operates using both sensors, creating a 28µm x 14µm pixel.

High sensitivity mode permits much greater scanning speeds in low light. It can also allow for reduced

lighting levels.

The sensitivity mode is software controlled through GigE-compliant interface using the Sensitivity Mode

feature, part of the Image Format Controls set.

Figure 28: High Sensitivity Mode

In high sensitivity mode, the camera uses either a 14µm x 14µm pixel (1k and 2k models) or a 10µm x

10µm pixel (4k model) and captures the same image twice, resulting in a brighter image.
