Parameter Description

Set ParityDetection to FIXEDFRAME if camera has previous timingSet ParityDetection to FIXEDFRAME_INV if camera has previous timingSet ParityDetection to FI_SPARE, FI_LVAL or FI_DVAL if camera has previous timing. Frame grabber detects logic level at rising edge of FVAL.Set ParityDetection to FI_SPARE_INV, FI_LVAL_INV or FI_DVAL_INV if camera has previous timing. Frame grabber detects logic level at rising edge of FVAL.
