Abstract
A virtual reality device, a method for adjusting focal lengths automatically, a method for producing the virtual reality device and a computer readable medium are provided. The virtual reality device includes: at least one imaging device comprising an imaging portion and an elastic micro lens array, the elastic micro lens array being arranged at a light incident side of the imaging portion and configured to modulate an incident light, the imaging portion being configured to receive the incident light modulated by the elastic micro lens array and to convert intensity of the incident light into an electrical imaging signal; and a display device configured to generate a visual image from the electrical imaging signal outputted by the imaging portion, wherein the elastic micro lens array has lenses which have independently adjustable focal lengths.
