Threshold factor; if factor is over 100, it is used as constant threshold in cd/m2, regardless if a task position is given or not if factor is less than or equal to 100 and a task position is given, this factor multiplied by the average task luminance will be used as threshold for detecting the glare sources if factor is less than or equal to 100 and no task position is given, this factor multiplied by the average luminance in the entire picture will be used as threshold for detecting the glare sources, default 5. |

If \fIfactor\fR is less or equal than 100 and a task position is given, this \fIfactor\fR multiplied by the average task luminance will be used as threshold for detecting the glare sources. If \fIfactor\fR is less than or equal to 100 and no task position is given, this factor multiplied by the average luminance in the entire picture will be used as threshold for detecting the glare sources (not recommended). Default value of \fIfactor\fR is 2000 (fixed threshold method). |
