Description

FLD

MC_AccumulationMode_FLD

The sensor operates in the "Field accumulation mode". All the photocells are transferred (and thus cleared) every field during the vertical blanking interval.

This is the default value since most of the surveillance camera uses this mode; the field accumulation mode being the only one compatible with an electronic shutter feature on interlaced scan cameras.

The integration time is one field period.

FRAME

MC_AccumulationMode_FRAME

The sensor operates in the "Frame accumulation mode". The photocells constituting the odd field are transferred during the vertical blanking interval preceding the odd field readout. Similarly for the even cells.

The integration time of a photocell is one frame (two field period).
