E1:
Exposure time for ‘Bright’ pixels E1 can be set with the slider or input directly. E1
must be some fraction of the overall exposure time as defined by the Exposure
setting. Bright pixels are exposed for Texp – E1. See section 4.7.1.2 Exposure Controls.
E2:
Exposure time for Very Bright pixels. Can be set with slider or input directly. Very
Bright pixel exposure is Texp - E2. E2 must be some fraction of Texp and must be
greater than E1.
E3:
Exposure time for Ultra Bright pixels. Can be set with slider or input directly.
Ultra-Bright pixel exposure is Texp - E3. E3 must be some fraction Texp and greater
than of E2.
P1:
Percentage of camera output assigned to Dark pixels. Select from 15% to 100% in
5% steps. Normal setting is 30% to 70%. The Dark pixel information is contained from
0% output level to the P1 setting.
P2:
Percentage of camera output allocated to Bright pixels. Select from 15% to 100%
in 5% steps. P2 must be greater than P1. The Bright pixel information is contained
between the P1 to P2 output levels. To disable the E2 and E3 exposures, set P2 and
P3 to 100%.
P3:
Percentage of camera output assigned to Very Bright pixels. Select from 15% to
100% in 5% steps. The Very Bright pixel information is contained between the P2 to
P3 output levels. To disable the E3 exposure), set P3 to 100%.
The “Ultra-Bright” pixel information is contained between the P3 level and 100% of
the output.
Notes:
A good set of initial settings as follows:
E1: 90% or 95% of the overall exposure time
P1: 50%
P2, P3 both set to 100%.
4.7.2 Trigger Inputs
The Trigger Tab is used to set the camera trigger inputs and trigger settings – Figure 5.15.
The user can select from one of 6 input sources and set the active trigger edge to rising or
falling with optional signal debouncing.
