Camera Performance and Features
Linea HS Series Camera User's Manual
Black Level
The camera has a black level (offset) feature that allows a specified level to be subtracted from the
image data. The gain feature can then be used to return the peak image data to near output
saturation with the result being increased image contrast.
First, determine the offset value to subtract from the image with the current gain setting. Then set
this as a negative offset value and apply additional gain to achieve the desired peak image data
values.
Note:
A positive offset value is not useful for contrast enhancement. However, it
can be used while measuring the dark noise level of the camera to ensure zero
clipping is not present.
Changing Output Configuration
Pixel Format
See the section Image Format Control Category in Appendix A for GenICam features associated
with this section and how to use them
Related Feature:
The camera can output video data as 8-bit or 12-bit.
Use the Mono8 Pixel Format to process image data as one, or two separate image planes.
Note:
Pixel Format, and associated features, can only be changed when the image
transfer to the frame grabber is stopped. Refer to the Acquisition and Transfer
Control Category in the appendix for details on stopping and starting the
acquisition.
For example, to change from 8-bit to 12-bit pixel format:
1.
In Acquisition and Transfer Control category, set Stop Acquisition.
2.
In Image Format category, set Pixel Format to Mono 12 (or BGR 12 if supported).
3.
In the host frame grabber configuration, set Pixel Depth to 12.
4.
In Acquisition and Transfer Control category, set Start Acquisition.
