Image processing method and apparatus of terminal, and terminal

An image processing method, comprising:

• receiving, by a terminal, a photographing instruction, wherein the terminal comprises a monochrome camera and a color camera, and wherein the monochrome camera and the color camera are disposed side by side;
• controlling, by the terminal, according to the photographing instruction, the monochrome camera and the color camera to simultaneously photograph a current scene, to obtain a monochrome image and a color image of the current scene;
• obtaining, by the terminal, a luminance component and a chrominance component of the color image;
• fusing, by the terminal, the luminance component with the monochrome image to obtain a luminance-fused component;
• and
• obtaining, by the terminal, a target color image according to the luminance-fused component and the chrominance component.

An apparatus, comprising:

• an image processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the image processor, the program including instructions to:
• receive a photographing instruction, and control, according to the photographing instruction, a monochrome camera and a color camera in a terminal, to simultaneously photograph a current scene, to obtain a monochrome image and a color image of the current scene, wherein the monochrome camera and the color camera are disposed side by side;
• obtain a luminance component and a chrominance component of the color image;
• fuse the luminance component with the monochrome image to obtain a luminance-fused component;
• and
• obtain a target color image according to the luminance-fused component and the chrominance component.

A terminal, comprising:

• a monochrome camera;
• a color camera, wherein the monochrome camera and the color camera are disposed side by side;
• and
• an image processor coupled to the monochrome camera and the color camera;
• wherein the image processor is configured to:
• receive a photographing instruction;
• and
• control, according to the photographing instruction, the monochrome camera and the color camera to simultaneously photograph a current scene, to obtain a monochrome image and a color image of the current scene;
• and
• wherein the image processor is further configured to:
• obtain a luminance component and a chrominance component of the color image;
• fuse the luminance component with the monochrome image to obtain a luminance-fused component;
• and
• obtain a target color image according to the luminance-fused component and the chrominance component.
