11.0 SR-100 & SR-100P CONTROL USING TVIS-7 USER
INTERFACE
The SR-100 (formerly known as the TVIS-7º) and the SR-100P may be controlled through
various sources including the TVIS-7º User Interface GUI which provides a Windows-based
control program (Graphical User Interface) for the SR-100P. Detailed descriptions for using
these controls are described in this section.
Video Control
Flat-Field-Correction: The Photon camera core includes internal mechanisms for periodically
improving image quality via a process called "flat-field correction" (FFC). During FFC, a small
calibration flag rotates in front of the detector array, presenting a uniform temperature (i.e. a "flat
field") to every detector element. While imaging the flat-field, the camera updates correction
coefficients, resulting in a more uniform array output. The video image is frozen during the entire
process, which takes approximately half a second, and it resumes automatically thereafter.
Repeating the FFC operation often prevents the imagery from appearing "grainy". This is
especially important when camera temperature is fluctuating, such as immediately after turn-on
and/or when ambient temperature is drifting. FFC can be commanded manually at any time
using the "Do FFC" button.
1. Automatic. In the Automatic FFC mode, the camera performs FFC whenever its
temperature changes by a specified amount or at the end of a factory specified
period of time (whichever comes first).
