Method and apparatus for controlling screen of terminal device to emit light

An apparatus for controlling a screen of a terminal device to emit light, comprising:

• a processor, and
• a memory, configured to store executable instruction of the processor;
• wherein, the processor is configured to:
• determine whether a screen flash lamp function is in an active state when the terminal device is in a photographing mode, wherein the screen flash lamp function enables the screen to serve as a flash lamp;
• and
• control the screen to emit light as a flash lamp according to a first color temperature correction scheme if the screen flash lamp function is in the active state, wherein the first color temperature correction scheme is configured to adjust a color temperature of the screen from an original color temperature to a target color temperature, and wherein the original color temperature is a color temperature when the screen emits light without color shift correction,
• wherein the processor is further configured to:
• determine a grayscale voltage for each color channel of the screen according to the first color temperature correction scheme;
• and
• control the screen to emit light as a flash lamp using the determined grayscale voltages.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a terminal device, causes the terminal device to perform a method for controlling a screen of the terminal device to emit light, the method comprising:

• determining whether a screen flash lamp function is in an active state when the terminal device is in a photographing mode, wherein the screen flash lamp function enables the screen to serve as a flash lamp;
• and
• controlling the screen to emit light as a flash lamp according to a first color temperature correction scheme if the screen flash lamp function is in the active state, wherein the first color temperature correction scheme is configured to adjust a color temperature of the screen from an original color temperature to a target color temperature, and wherein the original color temperature is a color temperature when the screen emits light without color shift correction,
• wherein the controlling the screen to emit light as a flash lamp according to a first color temperature correction scheme if the screen flash lamp function is in the active state comprises:
• determining a grayscale voltage for each color channel of the screen according to the first color temperature correction scheme;
• and
• controlling the screen to emit light as a flash lamp using the determined grayscale voltages.
