Image processing method and electronic device supporting same

An electronic device comprising:

• a display;
• an image sensor including a plurality of pixels;
• and
• a processor,
• wherein the processor is configured to:
• set a first pixel subset of the plurality of pixels to have a first sensitivity or a first exposure time;
• set a second pixel subset of the plurality of pixels to have a second sensitivity or a second exposure time;
• obtain image data of an external subject through the first pixel subset and the second pixel subset;
• identify attribute information of first sub-image data, which corresponds to the first pixel subset, and attribute information of second sub-image data, which corresponds to the second pixel subset, of the image data;
• select the first sub-image data based on information on surrounding brightness of the electronic device and, if focus information corresponding to the external subject cannot be obtained for the first sub-image data, then select the second sub-image data, based at least on the attribute information of the first sub-image data and the attribute information of the second sub-image data;
• determine the focus information corresponding to the external subject using the first sub-image data or the second sub-image data;
• generate third sub-image data using the second sub-image data to substitute data areas corresponding to the first sub-image data when the first sub-image data is selected;
• and
• output, to the display, image data, which is obtained by synthesizing the second sub-image data and the third sub-image data.

A method for processing an image, which is executed in an electronic device including a processor and an image sensor including a first pixel subset having at least one pixel with a first sensitivity and a second pixel subset having at least one pixel with a second sensitivity, the method comprising:

• obtaining, by using the processor, image data of a subject outside the electronic device through the image sensor;
• identifying attribute information of first sub-image data, which corresponds to the first pixel subset, and attribute information of second sub-image data, which corresponds to the second pixel subset, of the image data;
• selecting the first sub-image data based on information on surrounding brightness of the electronic device and, if focus information corresponding to the external subject cannot be obtained for the first sub-image data, then selecting the second sub-image data, based at least on the attribute information of the first sub-image data and the attribute information of the second sub-image data;
• determining the focus information corresponding to the external subject using the first sub-image data or the second sub-image data;
• generating third sub-image data using the second sub-image data to substitute data areas corresponding to the first sub-image data when the first sub-image data is selected;
• and
• outputting, to the display, image data, which is obtained by synthesizing the second sub-image data and the third sub-image data.
