Patent ID: 7762676

Claim:
A method for enhancing privacy on a multi-view display, said method comprising: a) displaying a primary image on a first display view of a multi-view display, wherein said first display view provides unobstructed viewing by a viewer positioned at a first location but provides an increasingly obscured view as a viewer's position moves away from said first position; b) determining whether text is present in said primary image; c) selecting a mask image with an image-dependent pattern selector wherein said image-dependent pattern selector selects a text mask for said mask image when text is present in said primary image and said image-dependent pattern selector selects a noise mask for said mask image when text is not present; and d) displaying said mask image on a second display view of said multi-view display, wherein said second display view provides unobstructed viewing by a viewer positioned at a second position but provides an increasingly obscured view as a viewer's position moves away from said second position.
