7.12.1. Thresholds in the Detection operating mode
In the “Detection” operating mode, an upper and a lower threshold can be set for each individual hue, for sa-
turation and for brightness. And thus a separate window width is possible for each channel.
Switching points:
The following switching points are calculated on the basis of the measured value during Teach-In:
Hoff
Lon
Hon
Loff
Measurement
Hoff = Hon + Hysteresis
Hon = Hue value + window size
Lon = Hue value – window size (this result can easily become negative)
Loff =
Lon – Hysteresis (this result can easily become negative)
Only the Hon and Lon threshold values can be changed with wTeach2 software. The other values are calcula-
ted on the basis of hysteresis, although hysteresis is not a fixed value itself but rather a calculated value as well.
