Claim 19:
20. An image display control method for a head-mounted display device, the head-mounted display device comprising an optical imaging apparatus, an image source apparatus, a displacement apparatus, and an image display control apparatus, the image source apparatus being optically aligned with the optical imaging apparatus, the image source apparatus and the optical imaging apparatus being configured as an object-side telecentric optical path, the image source apparatus having a plurality of source images, each source image having a different virtual scene depth, the method comprising:
determining a displacement sequence of the displacement apparatus and a source image display sequence of the image source apparatus based on a virtual scene display depth range, each displacement in the displacement sequence corresponding to one source image in the source image display sequence and to one virtual scene display depth in the virtual scene display depth range;
controlling the image source apparatus to perform image blurring on a specified source image, so that at each time of source image projection, the specified source image is not clearly displayed, wherein a cyclic movement period of the image source apparatus is greater than a duration of vision of human eyes;
for any virtual scene display depth, determining from a pre-established correspondence relationship a displacement corresponding to the virtual scene display depth, controlling the displacement apparatus to move, according to the displacement, the image source apparatus to a corresponding target position, and determining from a pre-established correspondence relationship a source image corresponding to the virtual scene display depth;
after the image source apparatus reaches the target position, controlling the image source apparatus to perform source image projection, so as to display a clear virtual image of the determined source image.
