Abstract
An electronic device with a camera and a display that can output light to achieve a desired appearance of skin tone is provided. The display outputs light having a color temperature for lighting during picture taking. The electronic device analyzes a color temperature value of a capturing environment and compares that value with a preset value, calculates a difference value according to the comparing, and controls the display to adjust the color temperature of the light accordingly. A color temperature adjusting method of the electronic device is also provided.
Claims13
An electronic device, comprising:
- a camera for capturing a picture;
- and
- a display displaying a graphical user interface (GUI) and outputting light for lighting during picture taking;
- a face identifying module identifying at least one face in the picture to be captured by the camera;
- a color temperature determining module analyzing a color temperature value from a part of the at least one face of the picture;
- a brightness determining module analyzing a brightness value from a part of the at least one face of the picture;
- and
- a processor;
- wherein the electronic device stores a color temperature preset value and a brightness preset value;
- and
- the processor compares the analyzed color temperature value and the analyzed brightness value of the at least one face in the picture to be captured with the color temperature preset value and the brightness preset value, and calculates a color temperature difference value and a brightness difference value;
- and controls the display to adjust a color temperature and a brightness of the light according to the color temperature difference value and the brightness difference value.
A color temperature adjusting method of an electronic device, the color temperature adjusting method comprising:
- storing a color temperature preset value and a brightness preset value;
