Apple Reveals an HMD System that corrects damaged or corrupted data that would usually present warped imagery

1 cover Apple Glass (2)


Today the US Patent & Trademark Office published a patent application from Apple that relates to error concealment related to a future head-mountable device including glasses.


In various implementations, a head-mountable device (HMD) includes a display. In some implementations, the display presents frames (e.g., video frames) that the HMD obtains. In some implementations, a current frame includes an error. For example, in some implementations, the current frame includes corrupted/damaged data, or the current frame is missing data.


Presenting a frame with corrupted/damaged/missing data sometimes results in misshaped objects (as seen below in FIG. 9C), dark lines across the display, and/or erroneous objects that are not present in the frame. As such, the HMD performs an error correction operation to compensate for the corrupted/damaged/missing data.


Apple's patent FIG. 9C below is a diagram that illustrates a leftward warping operation based on the depth data associated with an updated view; FIG. 10A is a schematic diagram of an environment in which the HMD performs a warping operation based on depth data associated with a reference view

The patent will likely be more interesting to AR/VR developers, though techies of every stripe could review the details of Apple's patent application number 20210118090 here. Technically, this is a continuation patent which updates Apple's granted patent 10,891,714 that was issued in January. Apple has added 20 new patent claims to their invention.


Considering that this is a patent application, the timing of such a product to market is unknown at this time.
