Closed loop verification of rendered content

摘要

An electronic display device provides closed-loop verification that specific content has been displayed by the display device. When desired digital image content is rendered as an image or video by the electronic display device, a confirmation signal is generated by one or more components of the display device to verify that the image content has been successfully displayed. The confirmation signal may include performance measurements of the one or more components of the display device and/or a signature output that is associated with a signature code embedded in the image content. The signature output uniquely identifies the digital image content.

主权项

1. An imaging system comprising:
an image processing unit configured to receive a digital image having a signature code embedded therein and convert an image data signal derived from the digital image into pixel-based data capable of being displayed; an image display device configured to generate the digital image on a display surface based on the pixel-based data; and a verification unit configured to determine, for each parameter included in a plurality of parameters associated with the image data signal, whether a value for the parameter matches an expected value range for the parameter, wherein one parameter included in the plurality of parameters comprises a signature output that is associated with the signature code and uniquely identifies the digital image, wherein the image display device comprises: a light source configured to illuminate at least a portion of the image on the display surface; and an optical assembly configured to direct light from the light source to the display surface.
