Hardware LUT

uEye Camera Manual Version 3.80

Hardware LUT

This tab provides settings for the hardware LUT curve of the GigE uEye HE camera. Each look-up table (LUT) for the uEye contains modification values for the image brightness and contrast parameters. When a LUT is used, each brightness value in the image will be replaced by a value from the table. LUTs are typically used to enhance the image contrast or the gamma curve.

Hinweis

This tab is only available if a GigE uEye camera is opened in the uEye Demo.


Hardware LUT

Channel
In this drop down box, you can choose whether you want to display the LUT for all channels or just for red, green or blue.
Split points
The LUT has 32 knee points by default. Knee points are used for defining the individual sections of the curve. When you select the Split points check box, each knee point is split into two separate points. Only the start and end points of each curve section can be defined independently of the adjacent sections.
Presets
In this drop down box, you can select and load predefined LUT curves. The following LUT curves are available:

Linear

Linear LUT curve without effect

Negative

Predefined LUT, inverts the image

Glow1

Predefined LUT, false-color representation of the image

Glow2

Predefined LUT, false-color representation of the image

Astro1

Predefined LUT, false-color representation of the image

Rainbow1

Predefined LUT, false-color representation of the image

Map1

Predefined LUT, false-color representation of the image

Cold/Hot

Predefined LUT, false-color representation of the image

Sepic

Predefined LUT, uses sepia toning for coloring the image

Only red

Predefined LUT, shows only the red channel of the image

Only green

Predefined LUT, shows only the green channel of the image

Only blue

Predefined LUT, shows only the blue channel of the image

Convert color to gray
When you are using a GigE uEye HE color camera, you can convert the color images to monochrome in the camera before applying the LUT curve. This setting is recommended if you want to use a LUT for false-color representation. The images are transferred in RGB format.
Output
The diagram shows that part of the LUT curve that is selected in the Channel box. You can drag and drop each knee point of the curve. To draw a smooth curve for the selected channel, left-click on a blank space next to the curve.
Mirror X/Y
These buttons allow mirroring the curve about the X and Y axes.
Load/Save
Click Save to save the current LUT curve to a text file. With Load, you can load a saved LUT curve from a file.
Enable hardware LUT
Enables/disables the current LUT curve.

Default

Click this button to reset all parameters to the model-specific defaults.
