  • an image sensor that includes a pixel array including a plurality of pixels arranged in a matrix having rows and columns, andat least one processor configured to control operations of;

    obtaining an image data set;

    by processing the image data set, identifying a first pixel group including at least one first pixel corresponding to a first subject from among the plurality of pixels and a second pixel group including at least one second pixel corresponding to a second subject from among the plurality of pixels except the at least one first pixel;

    determining a first distance between the electronic device and the first subject and a second distance between the electronic device and the second subject;

    determining a first exposure setting value according to the first distance and a second exposure setting value according to the second distance;

    setting the first exposure setting value to the first pixel group corresponding to the first subject and setting the second exposure setting value to the second pixel group corresponding to the second subject; and

    capturing an image by using the image sensor in which the first pixel group corresponding to the first subject is set to the first exposure setting value and the second pixel group corresponding to the second subject is set to the second exposure setting value.
