HDR Mode#

The HDR Mode feature increases the dynamic range during image acquisition which results in a larger measurement range.

该功能的使用#

运作原理#

The HDR Mode feature allows you to include the brighter and darker areas of your target scene in your image, i.e., the areas closer to and further away from the camera. This increases the dynamic range of the camera.

To do so, two images are taken and then combined to form an HDR image. It is important that the objects in the scene don't move between the individual exposures.

The first image will be taken with a longer exposure time in order to capture the scene further away from the camera. The exposure time of the second image must be lower than that of the first to capture the scene closer to the camera.

信息

The HDR mode reduces the maximum possible frame rate. The frame rate is 20 fps when the Fast Mode feature is enabled. Otherwise, the frame rate is 10 fps.

Configuring the HDR Mode#

  1. Enable the HDRMode parameter.
  2. Set the ExposureTimeSelector parameter to Stage1.
  3. Set the ExposureTime parameter to the desired exposure time.
  4. Set the ExposureTimeSelector parameter to Stage2.
  5. Set the ExposureTime parameter to the desired exposure time.
    The upper limit for the Stage 2 exposure time is 500 µs, i.e., half of the maximum exposure time possible.
