Abstract
An electronic device for controlling a brightness of a light source and an operating method of the electronic device are provided. According to the electronic device and the operating method, an image including an ambient environment of a light source is captured, information of an exposure of the captured image is obtained, information about a brightness of the ambient environment of the light source is determined based on the information about the exposure, and a brightness of the light source is controlled based on the determined information about the brightness of the ambient environment.
Claims17
A method of controlling a brightness of a light source by an electronic device, the method comprising:
- capturing an image including an ambient environment of the light source;
- obtaining information about an exposure of the captured image;
- determining a brightness value of the ambient environment of the light source based on the information about the exposure and at least one luminance value of the captured image;
- and
- controlling the brightness of the light source based on the determined brightness value of the ambient environment,
- wherein the light source includes a display of the electronic device
- wherein the controlling of the brightness of the light source comprises controlling the brightness of the light source based on data obtained by training based on a record of adjusting, by a user, the brightness of the light source.
An electronic device comprising:
- a display;
- a camera;
- a memory storing one or more instructions;
- and
- at least one processor configured to execute the one or more instructions stored in the memory to:
- control the camera to capture an image including an ambient environment of the display,
- obtain information about an exposure of the captured image,
- determine a brightness value of the ambient environment of the display based on the information about the exposure and a luminance value of the captured image, and
- control a brightness of the display based on the determined brightness value of the ambient environment,
- wherein the at least one processor is further configured to execute the one or more instructions stored in the memory to control a brightness of the display based on data obtained by training based on a record of adjusting, by a user, the brightness of the display.
A non-transitory computer-readable recording medium having an executable program recorded thereon, wherein the program, when executed by a computer, instructs the computer to perform:
- capturing an image including an ambient environment of a light source;
- obtaining information about an exposure of the captured image;
- determining a brightness value of the ambient environment of the light source based on the information about the exposure and a luminance value of the captured image;
- and
- controlling the brightness of the light source based on the determined brightness value of the ambient environment,
- wherein the light source includes a display of an electronic device, and
- wherein the controlling of the brightness of the light source comprises controlling the brightness of the light source based on data obtained by training based on a record of adjusting, by a user, the brightness of the light source.
