JVC TK-C1460B White spot compensation, Specifications, Operation method, Dimensions Unit mm

White spot compensation
CCDs have the general characteristic that white spots appear on the screen when the CCD is
operated at high temperatures or when they are used with a slow shutter speed.
This unit has a built-in white spot compensation function to reduce these white spots.
(The number and the size of the white spots changes according to the use temperature, the
shutter speed, etc. Furthermore, there is a limit on the number of white spots that can be
compensated.)
Operation method	1.	Attach a lens cap or similar.
