ELECTRONIC SHUTTER
There are two electronic shutter modes in S5C7214X01.
One is a Fixed Iris mode that controls shutter speed through parallel interface with the external pin. The other is an
Auto Iris mode that controls the electronic Iris automatically by detecting the amount of light of current objects from
the signal process IC.
