Abstract

The present invention discloses an image processing method. The image processing method includes at a portable multifunction device with an LED (light emitting diode) flash, including at least two LEDs, a camera, including a color sensor, and one or more processors, obtaining, by the camera, a first image, when the LED flash emits first light or when the LED flash does not emit light; obtaining, by the camera, a second image, when the LED flash emits second light, wherein the second light has a specific wavelength; and combining, by the one or more processors, the first image and the second image to generate a third image. By using the specific wavelength, the first aspect improves beautification of a human skin in an image captured by a camera.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method, an image processing device, a portable multifunctional device and a computer-readable storage medium. Background technique [0002] With the growth of digital cameras and mobile phones with cameras, the image quality of human faces becomes more and more important. When using the front camera of a mobile phone to take pictures of human faces, the image quality of human faces is the most concerned issue. [0003] Some cameras have image processing capabilities to beautify the face, such as removing spots or freckles using smoothing filters or noise reduction filters. Some spots or freckles can be eliminated or removed by smoothing filter or noise reduction filter. In addition, in order to avoid excessively smooth output of facial contours or shapes such as eyes, mouth, and nose, an edge-preserving filter is used. When an edge preserving filter ...
