Description

Packit 1f69a5

RadioacTV does *NOT* detect a radioactivity. It detects a difference

Packit 1f69a5
from previous frame and blurs it.

Packit 1f69a5

RadioacTV has 4 mode, normal, strobe1, strobe2 and trigger.

Packit 1f69a5
In trigger mode, effect appears only when the trigger property is TRUE.

Packit 1f69a5

strobe1 and strobe2 mode drops some frames. strobe1 mode uses the difference between

Packit 1f69a5
current frame and previous frame dropped, while strobe2 mode uses the difference from
Packit 1f69a5
previous frame displayed. The effect of strobe2 is stronger than strobe1.
