Virtual reality display device and method for presenting picture

A method for presenting a virtual reality picture, comprising:

• displaying a first image element of a virtual reality scene through a first display screen in a virtual reality display device;
• displaying a second image element of the virtual reality scene through a second display screen in the virtual reality display device, upon being zoomed by a zoom assembly in the virtual reality display device and reflected by a semi-reflective lens in the virtual reality display device, the second image element being superimposed with the first image element to present a scene picture of the virtual reality scene;
• and
• displaying, in response to a change in an eyeball focus position of a wearer of the virtual reality display device, the second image element that is updated, through the second display screen, upon being zoomed by the zoom assembly and reflected by the semi-reflective lens, the second image element being superimposed with the first image element to present a scene picture of the virtual reality scene,
• wherein an imaging position of the second image element and definition of image sub-elements contained in the second image element are related to the eyeball focus position.

An apparatus for presenting a virtual reality picture, comprising:

• a memory operable to store computer-readable instructions;
• and
• a processor circuitry operable to read the computer-readable instructions, the processor circuitry when executing the computer-readable instructions is configured to:
• display a first image element of a virtual reality scene through a first display screen in a virtual reality display device;
• display a second image element of the virtual reality scene through a second display screen in the virtual reality display device, upon being zoomed by a zoom assembly and reflected by a semi-reflective lens in the virtual reality display device, the second image element being superimposed with the first image element to present a scene picture of the virtual reality scene;
• and
• display, in response to a change in an eyeball focus position of a wearer of the virtual reality display device, the second image element that is updated, through the second display screen, upon being zoomed by the zoom assembly and reflected by the semi-reflective lens, the second image element being superimposed with the first image element to present a scene picture of the virtual reality scene,
• wherein an imaging position of the second image element and definition of image sub-elements contained in the second image element are related to the eyeball focus position.
