Multiple Exposure to Increase Image Resolution and Dynamic Range using Zoom Lens and Different Aperture
This innovation is a method to increase image resolution by using multiple exposures and different aperture settings, combining them to create a high dynamic range image. Images can be taken at different or same exposure times and the exact aperture setting can be determined by the user or by an initial estimate of the dynamic range of the scene. A...
