Method and device for processing digital image, and computer-readable recording medium

摘要

There is provided a method of processing a digital image including: (a) obtaining a plurality of images; (b) converting the plurality of images into histograms; (c) setting one of the plurality of images as a reference image and another of the plurality of images as a comparison target image; (d) adjusting a distribution of the histogram of the reference image to match a distribution of the histogram of the comparison target image to produce an adjusted reference image; (e) comparing a difference between the adjusted reference image and the comparison target image to produce a masking image; (f) applying the masking image to the comparison target image to produce an adjusted comparison target image; and (g) combining the reference image and the adjusted comparison target image to produce a high dynamic range (HDR) image. Accordingly, even if there is a complex motion on a subject, a clear image without an image overlap or a ghost effect may be obtained when producing the HDR image.

1. A method of processing a digital image, comprising:
receiving a plurality of images; converting the plurality of images into histograms; setting a first of the plurality of images as a reference image; setting a second of the plurality of images as a comparison target image; generating an adjusted reference image based on the reference image and the comparison target image; generating a masking image based on the adjusted reference image and the comparison target image; generating an adjusted comparison target image by applying the masking image to the comparison target image; and combining the reference image and the adjusted comparison target image to generate a high dynamic range (HDR) image.
