HDR
On this tab, you can configure the HDR mode settings for your uEye camera.
This feature is currently only available for the UI-122x-M/C and UI-522x-M/C uEye models.
Figure 83: uEye properties - HDR
By exposing the sensor cells in two or three phases, the HDR (High Dynamic Range) function
enhances dynamics during image capture. This means that very bright and very dark image parts are
displayed in one image without causing overexposure.
· Number of knots
In this drop down box, you can choose whether the HDR curve should have one or two definable
knee points.
· Brightness/Time
The x value of a knee point indicates the first phase in percent of the currently set exposure time.
The y value gives the proportion of maximum pixel intensity for this phase in percent.
· Default
Click this button to reset all parameters to the model-specific defaults.
Example
A setting of x = 60, y = 80 would therefore produce the following results:
The first exposure phase lasts for 60% of the set exposure time. In this first exposure phase, all
pixels are exposed to at most 80% of maximum pixel intensity and remain at 80% until this phase
