1. A portable communication device comprising:
a housing including a front plate and a rear plate opposite to the front plate;
a display disposed in the housing and visible through the front plate;
an illuminance sensor disposed between the display and the rear plate such that the illuminance sensor is overlapped with a portion of the display when viewed from above the front plate; and
a processor disposed in the housing and operatively connected with the display, the processor being configured to:
output an image via the display,
obtain first illuminance data corresponding to an illuminance sensed by the illuminance sensor for an image frame while the image is output via the display,
in response to the obtaining of the first illuminance data, identify display parameter information associated with the first illuminance data, the display parameter information including display brightness information obtained while the image is output via the display,
in response to the display brightness information corresponding to a first brightness of the display, select a first illumination value,
in response to the display brightness information corresponding to a second brightness of the display different from the first brightness, select a second illumination value different from the first illumination value,
based on the selecting of the first illumination value or the second illumination value, obtain second illuminance data, and
adjust a brightness of the display based at least in part on the first illumination value or the second illumination value selected as the second illuminance data while the image is output via the display,
wherein the first illumination value is determined as the illuminance sensor senses a light emitted while a first image having the first brightness is output via the display in a state in which an external light is blocked off,
wherein the second illumination value is determined as the illuminance sensor senses a light emitted while a second image having the second brightness is output via the display in the state in which the external light is blocked off, and
wherein the display brightness information comprises at least one of color on pixel ratio (COPR) information about the image output via the display or active matrix organic light emitting diode (AMOLED) off ratio (AOR) information about the display.
 
6. A method of sensing illuminance by an electronic device, the method comprising:
outputting an image via a display of the electronic device;
obtaining first illuminance data corresponding to an illuminance sensed by an illuminance sensor of the electronic device for an image frame while the image is output via the display;
in response to the obtaining of the first illuminance data, identifying display parameter information associated with the first illuminance data, the display parameter information including display brightness information obtained while the image is output via the display;
in response to the display brightness information corresponding to a first brightness of the display, selecting a first illumination value;
in response to the display brightness information corresponding to a second brightness of the display different from the first brightness, selecting a second illumination value different from the first illumination value;
based on the selecting of the first illumination value or the second illumination value, obtaining second illuminance data; and
adjusting a brightness of the display based at least in part on the first illumination value or the second illumination value selected as the second illuminance data while the image is output via the display,
wherein the first illumination value is determined as the illuminance sensor senses a light emitted while a first image having the first brightness is output via the display in a state in which an external light is blocked off,
wherein the second illumination value is determined as the illuminance sensor senses a light emitted while a second image having the second brightness is output via the display in the state in which the external light is blocked off, and
wherein the display brightness information comprises at least one of color on pixel ratio (COPR) information about the image output via the display or active matrix organic light emitting diode (AMOLED) off ratio (AOR) information about the display.
 
11. A non-transitory storage medium storing instructions, the instructions being configured to be executed by at least one circuit to cause an electronic device to perform at least one operation, the at least one operation comprising:
outputting an image via a display of the electronic device;
obtaining first illuminance data corresponding to an illuminance sensed by an illuminance sensor of the electronic device for an image frame while the image is output via the display;
in response to the obtaining of the first illuminance data, identifying display parameter information associated with the first illuminance data, the display parameter information including display brightness information obtained while the image is output via the display;
in response to the display brightness information corresponding to a first brightness of the display, selecting a first illumination value;
in response to the display brightness information corresponding to a second brightness of the display different from the first brightness, selecting a second illumination value different from the first illumination value;
based on the selecting of the first illumination value or the second illumination value, obtaining second illuminance data, and
adjusting a brightness of the display based at least in part on the first illumination value or the second illumination value selected as the second illuminance data while the image is output via the display,
wherein the first illumination value is determined as the illuminance sensor senses a light emitted while a first image having the first brightness is output via the display in a state in which an external light is blocked off,
wherein the second illumination value is determined as the illuminance sensor senses a light emitted while a second image having the second brightness is output via the display in the state in which the external light is blocked off, and
wherein the display brightness information comprises at least one of color on pixel ratio (COPR) information about the image output via the display or active matrix organic light emitting diode (AMOLED) off ratio (AOR) information about the display.
