Exposure Overlap Time Max#

相机的 Exposure Overlap Time Max 功能使您可以优化重叠图像的采集

如果要最大程度地提高相机的帧速率,即要以尽可能高的速率触发,使用此参数特别有用。

仅当您在触发宽度触发控制曝光模式下操作相机时,此参数才可用。

该功能的使用#

运作原理#

您可以使用重叠图像采集来提高相机的帧速率。通过重叠图像采集,当相机仍在读取前一图像的传感器数据时,即可开始新图像的曝光。

触发宽度触发控制曝光模式下,相机不“知道”在触发时间结束之前将图像曝光多长时间。因此,相机无法完全优化重叠图像采集

To avoid this problem, enter a value for the ExposureOverlapTimeMax parameter that represents the shortest exposure time you intend to use (in µs). This helps the camera to optimize overlapping image acquisition.

信息

If you have entered a value for the ExposureOverlapTimeMax parameter, make sure to never apply a trigger signal that is shorter than the given parameter value.

设置最长曝光重叠时间#

要在触发宽度或触发控制曝光模式下优化相机的帧速率:

  1. Set the TriggerMode parameter to TriggerWidth or TriggerControlled.
  2. Set the ExposureOverlapTimeMode parameter (if available) to Manual.
  3. Enter a value for the ExposureOverlapTimeMax parameter that represents the shortest exposure time you intend to use (in µs).

Example: Assume that you want to trigger the camera to apply exposure times in a range from 3000 μs to 5500 μs. In this case, set the camera's ExposureOverlapTimeMax parameter to 3000.

附加参数#

On some camera models, the ExposureOverlapTimeMode parameter is available.

如果该参数可用,则可以将其设置为以下值:

  • Automatic: The value of the ExposureOverlapTimeMax parameter is set to the maximum possible value and can't be modified. This is the default setting.
  • Manual: You can configure the ExposureOverlapTimeMax parameter as desired.

如果参数不可用,则相机始终以“手动”模式运行。
