Title:

METHOD FOR GENERATING HDR IMAGE OF SCENE BASED ON TRADEOFF BETWEEN BRIGHTNESS DISTRIBUTION AND MOTION

Document Type and Number:

Japanese Patent JP2016134919

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method for generating an HDR image of a scene on the basis of a tradeoff between a brightness distribution and motion.SOLUTION: The method includes, when a current frame fimaging a scene is captured under a current exposure E, setting an exposure Efor a next frame fas a function of the current exposure E, of a first brightness distribution Hfullof colors of pixels of the current frame f, and of a second brightness distribution Hmotionof colors of those pixels weighted by motion of those pixels, such that the motion is evaluated for those pixels in comparison with a previous frame f, capturing the next frame funder the set exposure E, and merging the next frame fwith at least the current frame finto an HDR image.SELECTED DRAWING: Figure 2
