Figure 6 - Lepton Power Sequencing
3.2 FFC States
Lepton is factory calibrated to produce an output image that is highly uniform, such as shown in Figure 7 (a),
when viewing a uniform-temperature scene. However, drift effects over long periods of time degrade uniformity,
resulting in imagery which appears grainier Figure 7 (b)) and/or blotchy (Figure 7 (c)). Columns and other pixel
combinations may drift as a group. These drift effects may occur even while the camera is powered off. Operation
over a wide temperature range (for example, powering on at -10 °C and heating to 65 °C without performing and
FFC) will also have a detrimental effect on image quality and radiometric accuracy.
For scenarios in which there is ample scene movement, such as most handheld applications, Lepton is capable of
automatically compensating for drift effects using an internal algorithm called scene-based non-uniformity
correction (scene-based NUC or SBNUC). However, for use cases in which the scene is essentially stationary, such
