ELECTRONIC SHUTTER
There are two electronic shutter modes in KS7214.
One is a Fixed Iris mode that controls shutter speed through parallel interface with external pin.
The other is a Auto Iris mode that controls electronic Iris automatically by detecting the light amount of current objects from the signal
process IC.
