SFRS Frame Rate

There are two main differences when running in

SFRS mode versus CFRS mode. The first is that

the Frame Rate is no longer the readout rate. In

SFRS mode there is no overlap of the Integration

and the readout. Therefore, at the top of each

Frame, Integration must first occur then readout.

The Frame Rate is now Integration plus readout.

The second major difference is the length of

readout. In CFRS mode, the only reason for

making the VF length larger than the WOI length

(vrd > wrd) is to add vertical blanking rows to

control the time between frames. In SFRS mode,

the time between frames is controlled by the

TRIGGER input pin, and therefore vertical

blanking serves no purpose.

Rather than have the user change the VF depth

(vrd), the imager uses the WOI depth (wrd).

Therefore, the Frame Rate equations are:

Frame Time (Tframe) =

Integration Time (Tint)+ Readout Time (Trd)

Where:

Integration Time (Tint) = (cintd + 1) * Trow

Readout Time (Trd) = Trow * (wrdd+1)

Row Time (Trow) = (vcwd+shAd+shBd+19) * MCLKperiod

Frame Rate = 1/Frame Time
