Augmented reality system and color compensation method thereof

An augmented reality system comprising:

• an image sensor, configured to capture an image of an actual scene;
• a display being light-transmissive, configured to display a virtual object;
• and
• a computing device, electrically connected to the image sensor and the display directly or indirectly, and configured to:
• set a preset object position of the virtual object with respect to the actual scene;
• map the image of the actual scene to a field of view (FOV) of the display to generate a background image with respect to the FOV of the display;
• perform color compensation on the virtual object according to a background overlapping region corresponding to the preset object position in the background image to generate an adjusted virtual object;
• and
• display the adjusted virtual object on the display according to the preset object position.

A color compensation method, applicable to an apparatus having an image sensor and a display being transparent and able to display a virtual object, wherein the virtual object has an original color, and wherein the method comprises:

• capturing an image of an actual scene by using the image sensor to generate a background image;
• comparing the virtual object of the display and the background image to determine an actual overlapping region of the virtual object and the background image;
• and
• determining a relationship between a background pass-through color brightness of the actual overlapping region of the background image after passing through the display and an original color brightness of the virtual object to accordingly adjust the original color brightness of the virtual object to a calibrated color brightness.
