2KSDI-Mini User's Manual
When automatic exposure is enabled, the camera calculates the average luma of a 1/5 height by 1/5
width zone and compares it to the Target Luma value. Adjustments are made to the exposure, gain and
aperture to reach the target value. Use the edit box or slider bar to adjust Target Luma. Move the auto
exposure zone by selecting its X and Y position with the drop down lists. Check the check box to
display the zone on the overlay.
Use the Exposure, Gain, and Aperture Range controls to ensure that the exposure, gain and aperture
stay within the desired range. The rate at which the camera modifies the parameters is controlled by the
Adjustment Speed slider.
“D” model cameras add a DC Iris auto exposure mode. In this mode the camera uses the calculated
average luma of the auto exposure zone to drive a voltage to the DC Iris lens. The lens will adjust its
aperture to keep a consistent luma level.
6.6 Gain/Level View
The Gain/Level view is shown in Figure 12.
6.6.1 Gain
Gain can be adjusted by selecting either the ISO level or directly setting the gain in dB.
The gain setting varies between non-RS and RS camera models. All models have a total analog and
digital gain that can be set from 0dB to 48dB. Non-RS cameras have gain up to 24dB applied with an
analog gain block, while any additional gain up to 48dB total is applied with a digital gain block, both
of which are on the sensor. RS models cameras have gain up to 26.6dB applied with an analog gain on
the sensor, while any additional gain up to 48dB total is applied with a digital gain block in the camera.
