获取Android相机Aperture和曝光时间

Question

Is there any API instruction or calculation to obtain the android camera Aperture F value, and the Exposure Time?

The Camera API exposes methods to get the White Balance, the Focal Length, etc, but I couldn't find anything related to the Aperture and the Exposure Time.

Thanks

Answer 1

In the Android Developer's Guide for ExifInterface , which is a class in the android.media API (not, the now deprecated Camera API), there is information for Aperture and Exposure Time

Sample code showing how it could be used is available at ExifHelper
