5.5.3 Integration Time Control
The Integration Time registers;
Table
Integration time for SFCM; sint[20:0], is measured in
MCLK cycles while the integration time for CFCM;
cint[15:0], is measured in Virtual Row times. Please re-
fer to
Frame and its relationship to the WOI.
A virtual frame is the mechanism by which the user con-
trols the integration time and frame time for the output
data stream. By adding additional rows or columns as
‘blanking’ to the WOI to form the Virtual Frame, the user
can control the amount of blanking in both horizontal
and vertical space.
Both the Virtual Frame Row Depth; vrd[13:0], and the
Virtual Frame Column Width; vcw[9:0] have a range of

Description
Description
The user should be careful to create a Virtual Frame
that is larger than the WOI. There is no logic in the sen-
sor interface to prevent the user from defining a Virtual
Frame smaller than the WOI. Therefore, pixel data may
be lost.
The Virtual Frame must be 1 row and 6 columns larger
than the WOI.
The Virtual Frame completely defines the integration
time in CFCM. Any changes to the WOI or how the WOI
is sampled has no effect on integration time.
