Method and apparatus for incorporating noise pattern into image on which bokeh processing has been performed

An operating method of an electronic device, comprising:

• obtaining at least one image corresponding to one or more external objects using at least one camera of the electronic device;
• identifying depth information of the one or more external objects based on the at least one image;
• identifying a first region corresponding to a first external object having a first depth level related to the depth information in the at least one image,
• identifying a second region corresponding to a second external object having a second depth level different from the first depth level and related to the depth information in the at least one image;
• generating a first noise pattern based on detecting noise included in the first region;
• performing bokeh processing on at least part of the second region, and
• generating a corrected image wherein the first noise pattern is incorporated into at least part of the bokeh-processed second region.

An electronic device, comprising:

• at least one camera;
• a memory;
• and
• a processor,
• wherein the processor is configured to:
• split an image into a first region corresponding to a first object having a first depth level and a second region corresponding to a second object having a second depth level different from the first depth level,
• generate a first noise pattern based on detecting noise distributed in the first region,
• generate a second noise pattern based on detecting noise distributed in the second region,
• perform bokeh processing on at least part of the second region, and
• generate a corrected image by incorporating the first noise pattern or the second noise pattern into the bokeh-processed second region.
