Device and method for dynamic range expansion in a virtual reality scene

A method for displaying content of a virtual reality scene in a virtual reality display device, the method comprising:

• determining a current viewing position of a user of the virtual reality display device;
• determining a dynamic range expansion function based on the current viewing position;
• applying the dynamic range expansion function to an area of the content of the virtual reality scene visible to the user from the current viewing position to produce a range-expanded area;
• and
• displaying the range-expanded area on the virtual reality display device.

A virtual reality display device for displaying content of a virtual reality scene, comprising:

• at least one processor configured to:
• determine a current viewing position of a user of the virtual reality display device;
• determine a dynamic range expansion function based on the current viewing position;
• apply the dynamic range expansion function to an area of the content of the virtual reality scene visible to the user from the current viewing position to produce a range-expanded area;
• and
• a display configured to display the range-expanded area.

A non-transitory machine readable medium having stored thereon machine executable instructions that, when executed on a processor, display content of a virtual reality scene in a virtual reality display device, the instructions causing the processor to:

• determine a current viewing position of a user of the virtual reality display device;
• determine a dynamic range expansion function based on the current viewing position;
• apply the dynamic range expansion function to an area of the content of the virtual reality scene visible to the user from the current viewing position to produce a range-expanded area;
• and
• display the range-expanded area on the virtual reality display device.
