6.3 SFRS Frame Time/Rate:
In Single Frame Rolling Shutter capture mode the Frame
time is defined as:
Frame time = T
Readout time is the amount of time to readout the data af-
ter integration of the row has been completed. It is defined
as follows:
Readout time = (vrd

6.3.1 Integration Time in SFRS mode
The Integration time in Single Frame Rolling Shutter cap-
ture mode is the same as in Rolling Shutter Capture
Mode. For further information, see
CFRS mode:” on page
in this mode the Integration time is NOT bounded by
the Frame time
6.4 Example of Frame time/rate and Integration Time
The following illustrates how to determine the Frame time/
rate and Integration time in both capture modes:
Assumptions:
1) Active Window of Interest = 1280 x 1024
2) Virtual Column Width
3) Virtual Row Depth (vrd
4) Sample & hold time (shs
5) Sample & hold time (shr
6) Integration Time
7) MCLK = 13.5 Mhz
