Abstract
A head wearable device, a method, and a system. The head wearable device may include a display, a camera, a buffer, and a processor. The buffer may be configured to buffer a portion of real scene image data corresponding to a real scene image from the camera. The processor may be configured to: perform a combined distortion correction operation; perform a foreground separation operation; perform a smoothing operation on blending values; perform a chromatic aberration distortion correction operation; receive virtual scene image data corresponding to a virtual scene image; blend processed real scene image data with the virtual scene image data to create a mixed reality scene image as mixed reality scene image data; and output the mixed reality scene image data to the display for presentation to a user.
