Patent: Method and device for simulating a wide field of view

Publication Number: 10176555

Abstract

It is disclosed a method for displaying input image data on a display device. The display device comprises a main display and a border display which at least partly surrounds the main display. The method comprises extrapolating the input image data to obtain extrapolated image data, displaying at least part of the input image data on the main display, and displaying at least part of the extrapolated image data on the border display.

Background

One possible application of Head Mounted Displays (HMDs) is the “Personal Display” (PD). A Personal Display is a Head Mounted Display that is tailored for watching movies or similar content. However, the field of view (FOV) of video or image data can be limited to .about.30 degrees, since the video content is usually shot with this field of view in mind, i.e. for normal video content it is assumed that the viewing distance from the screen is proportional to the screen diagonal so that the field of view is .about.30 degrees. While this field of view fits perfectly the requirements for normal television screens, it may still be uncomfortable to view movies at a field of view of .about.30 degrees looking through a Personal Display and to have the surrounding environment fully black.

Summary

According to a first aspect the disclosure provides a method for displaying input image data on a display device, the display device comprising a main display and a border display which at least partly surrounds the main display, the method comprising extrapolating the input image data to obtain extrapolated image data, displaying at least part of the input image data on the main display, and displaying at least part of the extrapolated image data on the border display.

According to a second aspect, the disclosure provides a display device, the display device comprising a main display, a border display which at least partly surrounds the main display, and a processor, configured to extrapolate input image data to obtain extrapolated image data, display at least part of the input image data on the main display, and display at least part of the extrapolated image data on the border display.
