Genie_TS_Series GigE Vision Camera
Bayer Mosaic Pattern
The Genie TS Color camera outputs raw Bayer image data using the mosaic pattern shown below.
Teledyne DALSA Sapera CamExpert tool interprets the raw Bayer output when the user enables the
Pre-Processing Software Bayer Decoder.

Gain and Black Level Control Details
The Genie TS series of cameras provide gain and black level adjustments. Dependent on the model
of camera, adjustments are available at the sensor as an analog variable and/or in the digital
domain. The gain and black level controls can make small compensations to the acquisition in
situations where lighting varies and the lens iris can not be easily adjusted. Optimal gain and black
level adjustments maximizes the Genie TS dynamic range for individual imaging situations. The
user can evaluate Gain and Black Level by using CamExpert.
Features and limitations are described below.
Black Level
offset is expressed as a digital number providing a +/- offset from the factory
setting. The factory setting optimized the black level offset for maximum dynamic range under
controlled ideal dark conditions.
Analog Gain
is expressed as a multiplication factor applied at the sensor level, before any FFC.
The increased gain increases the sensor dynamic range but with a non-proportional increase in
noise.
For each setting of analog gain, the sensor data has applied a unique Factory set Flat Field
Correction, to ensure uniform pixel response. which is applied after the analog gain stage but
before the digital gain stage.
When any Flat Field Correction is applied, the resulting gain multiplying factor is increased
based on the FFC calibration. As an example with Genie TS-12M with FFC Active and default
Black Offset, with an analog gain set to 2.65, the resulting multiplying factor is 2.75.
Digital Gain
is expressed as a multiplication factor applied after the Analog Gain and any FFC
stages, but note that increasing digital gain does not increase the low level resolution and
increases the sensor noise proportionately.
