SEMICONDUCTOR TECHNICAL DATA
6.0 Frame Rate and Integration Time Control
In addition to the minimum time required to readout the
selected resolution and WOI, the user has the ability to
control the frame rates while operating in either Contin-
uous Frame Rolling Shutter capture mode (CFRS) and
Single Frame Rolling Shutter (SFRS).
The frame rate can be defined as the time required to
readout an entire frame of data plus the required bound-
ary timing. This is done by varying the size of a number
of parameters identified in later sections, the main one
being the Virtual Frame surrounding the WOI.
Please refer to
Virtual Frame and its relationship to the WOI
.

6.1 CFRS Frame Time/Rate:
In Continuous Frame Rolling Shutter capture mode, the
Frame time is completely defined by the size of the Vir-
tual Frame and can be expressed as:
Frame Time = T

6.2 Integration Time in CFRS mode:
In Continuous Frame Rolling Shutter capture mode, the
Integration time is defined as:
Integration Time=T
