Face image replacement system and method implemented by portable electronic device

A face image replacement method implemented by an portable electronic device comprising an image capturing device and a display screen, the method comprising:

• capturing a person image of a user using the image capturing device of the portable electronic device;
• analyzing the person image to determine a face area of the person image according to face character data stored in a storage system of the portable electronic device;
• marking the face area with a rectangle area, and calculating a size of the rectangle area;
• obtaining a special image from the storage system, and adjusting a size of the special image according to the size of the rectangle area;
• replacing the face area of the person image with the special image to generate a face replacement image, wherein the replacing step comprises steps of:
• checking pixel points of the face area in the person image, determining whether a RGB (red, green, and blue) value of each of the pixel points is equal to a gray value, keeping a pixel point in the face area if the RGB value of the pixel point is equal to the gray value, or replacing the pixel point of the face area with a pixel point of the special image if the RGB value of the pixel point is not equal to the gray value;
• and
• displaying the face replacement image on the display screen.

A non-transitory storage medium having stored thereon instructions that, when executed by at least one microprocessor of an electronic device, causes the electronic device to perform a face image replacement method, the method comprising:

• capturing a person image of a user using an image capturing device of the electronic device;
• analyzing the person image to determine a face area of the person image according to face character data stored in a storage system of the electronic device;
• marking the face area with a rectangle area, and calculating a size of the rectangle area;
• obtaining a special image from the storage system, and adjusting a size of the special image according to the size of the rectangle area;
• replacing the face area of the person image with the special image to generate a face replacement image, wherein the replacing step comprises steps of:
• checking pixel points of the face area in the person image, determining whether a RGB (red, green, and blue) value of each of the pixel points is equal to a gray value, keeping a pixel point in the face area if the RGB value of the pixel point is equal to the gray value, or replacing the pixel point of the face area with a pixel point of the special image if the RGB value of the pixel point is not equal to the gray value;
• and
• displaying the face replacement image on a display screen of the electronic device.
