Bayer Mosaic Pattern
Genie Nano Color cameras output 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. CamExpert also provides an automatic white balance tool
to aid RGB gain adjustments.

OnSemi Python P1 Sensor Artifacts with Fast Readout Mode
Nano OnSemi (Python P1) sensor camera models with Fast Readout mode active have the row
blanking and row readout occur in parallel in the sensor. This reduces the total frame readout time
resulting in a faster maximum frame rate. As a consequence there are minor column artifacts (of
very low DN) which are typically of no significance and irrelevant for many imaging systems. Note
that these column artifacts will become more prominent as sensor gain is increased.
The image below shows a “dark” capture with Fast Readout Mode enabled and analog gain set to
maximum (8x). The artifacts will become visible as fixed pattern DN column variations near the left
edge of the video frame. There are darker columns followed by lighter columns as marked by the
overlay graphics. These DN variations are not random columns, but consistent between individual
OnSemi sensors operating in Fast Readout mode with high gain.
