[II] Quantization Level Adjustment (Video Level)
Use the target tracking function (TT) to adjust the level of the signal to be recognized as a target. If a small
value is set, even weak target signals will be input to the target detection circuit of the target tracking function.
However, many unnecessary signals are also input, which may cause unstable target acquisition or tracking. It
is important to set a value four or five greater than the value with which unnecessary signals are detected.
The quantization level is adjusted to an optimal value, so do not change it carelessly.
Do not change the set quantization level carelessly.
If the level deviates from the proper value, the TT
acquisition and tracking functions will deteriorate.
Otherwise, this may cause accidents.
