5.5.1 Offset
Dark level offset adjustment is possible. When 8 Bit are transmitted it can be changed
from 0 to 255. Please note that factory adjustment is optimized for S/N ratio and
sensitivity. You may lose dynamic range. Alter only if you operate at high
temperatures like +40 °C. It can be altered for each channel separately. (for 2 tap
Kodak CCDs).
5.6 AutoGain/AutoExposure
When the “Auto” checkbox is activated for cameras that provide for the
AutoGain/AutoExposure feature, the “Luminance” panel changes to show the settings
that apply to this mode of operation. The manual settings for gain and offset will
disappear since the luminance will be controlled automatically.
The automated luminance control algorithm takes advantage of both, exposure and
gain settings. First the exposure will be tried to adjust it such that a set brightness
value will be met. Once the highest exposure value has been reached the algorithm
will further increase luminance by increasing camera’s gain. The upper and lower
limits for both controls are available in the “Luminance” panel once the “Auto”
checkbox is checked.
The actual exposure is shown on the “Acquisition” panel and the actual gain is
displayed in the “Luminance” panel on the left to the “min” and “max” gain settings.
5.7 Auto tap balance (svs11002 and svs16000, 2 tap,versions only)
Advanced imaging sensors offer a two-tap operation for getting to higher frame rates.
A left and a right tap as on the following image have to be perfectly balanced in this
case in order to capture high quality images without any visible border on the join
between both taps.
Auto tap balance is usually switched “Off” during normal camera usage. It can be
activated for two modes:
 Once
 Continuous
