A reference image block in the environmental image that matches a display image on a display is detected by performing feature matching between the environmental image and the display image.
Position information of the reference image block in the environmental image is obtained. Depth information of the display is obtained according to an actual screen size of the display and a block size of the reference image block in the environmental image. At least one virtual object is displayed by the head-mounted device according to the position information and the depth information. The at least one virtual object is displayed as being anchored to at least one screen bezel of the display.

摘要： The disclosure provides a display driving device and an operation method thereof. The display driving device includes a timing controller circuit and a driving circuit. The timing controller circuit performs oblique filter processing on an original image frame by an oblique filter with an oblique filter mask matrix to generate a processed image frame. The oblique filter comprises an oblique high-pass filter or a smoothing filter. Original pixel data of a current pixel in the original image frame is replaced with new pixel data when the oblique filter mask matrix is configured for the current pixel. The driving circuit drives a display panel module according to the processed image frame. The display panel module includes a tilt lenticular lens layer having a first tilt angle. A second tilt angle of the oblique filter mask matrix of the oblique filter processing corresponds to the first tilt angle.
