Exposure of CameraSDK 1.1.1

Post by Ushikubo Tomohiro »

I use the CameraSDK to make original program.
I was changed the CameraSDK from 1.0.0 to 1.1.1.
I feel the setting of "Exposure" is changed.

1)Would you tell me the max value and min value of "Exposure"?
2)Can I use float value to set "Exposure"?

Thanks.

Hello -

The individual values for exposure have not changed in their meaning, but when the S250e camera was implemented, exposure did change.

In V100 and V120 series cameras, exposure ranges from 1 to 480, where each unit represents a fixed set of time that the imager is exposed based on the framerate.

In S250e cameras, exposure is handled slightly differently. One unit of exposure equals one microsecond. The range is a minimum of 10 to a maximum of 200 microseconds short of the total frame period. At 250fps this results in a range of 10-3800. At 125fps this results in a range of 10-7800.
