High Dynamic Range Image Acquisition with Multiple Exposure

摘要

Techniques for creating a high dynamic range (HDR) image with a commercially available digital camera from a series of images of a scene taken at different exposure levels and for displaying the HDR image on the built-in display device of the camera are provided. The approach uses blending images from the series to incorporate both scene shadow and highlight details, and removing "ghost" image artifacts that appear in the blended HDR image and movement in the scene in time originate in which the series images are captured. The use of a low computational resource for image blending and ghost removal processing operations, along with the ability to begin image blending and ghost removal prior to capturing all burst images, can be used to generate and display a tone mapping HDR image Significantly reduce the time required.
