Abstract
In accordance with one embodiment of the present disclosure, a difference is detected between a first image and a second image. The second image can include at least a portion of the first image reflected from a display panel and light from an object passing through the display panel.
Claims61
A method, comprising:
- generating a first image on a first side of a display panel using visible light, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image being passed through the display panel and user-viewable on a second side of the display panel;
- receiving light from an object located on a second side of the display panel;
- capturing a second image comprising at least a portion of the reflected portion of the first image and at least a portion of the received light;
- and
- detecting a difference between the first image and the second image.

A method, comprising:
- projecting, using visible light, a first image onto a first side of a display panel, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image being passed through the display panel and user-viewable on a second side of the display panel;
- at a first point in time, capturing a second image that comprises at least a portion of the reflected portion of the first image and light transmitted from an object in proximity with a second side of the display panel;
- at a second point in time, capturing a third image that comprises at least a portion of the reflected portion of the first image as well as light transmitted from the object, wherein the third image is subsequent to the second image;
- and,
- detecting a difference between the second image and the third image, wherein the difference is a representation of at least a portion of the object.

A method of detecting the presence of an object, the method comprising:
- generating, from a first image file, a first image on a first side of a display panel using visible light, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image passing through the display panel and viewable by a user on a second side of the display panel;
- receiving light from an object located on a second side of the display panel;
- capturing a second image comprising at least a portion of the reflected portion of the first image and at least a portion of the received light;
- generating a second image file from the second image;
- and
- detecting a difference between the first image and the second image by comparing the first image file and the second image file.

A non-transitory machine-readable medium, the machine-readable medium having stored thereon computer executable instructions to:
- project a first image on a first side of a display panel using visible light, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image being passed through the display panel and user-viewable on a second side of the display panel;
- generate a second image by capturing at least a portion of the reflected portion of the first image and at least a portion of light received from an object located on the second side of the display panel;
- and
- detect a difference between the first image and the second image.
1 more element
A system, comprising:
- an imager to project a first image on a first side of a display panel using visible light, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image being passed through the display panel and user-viewable on a second side of the display panel;
- an optical receiver configured to capture a second image that comprises at least a portion of the reflected portion of the first image and light received from an object located on the second side of the display panel;
- and
- a controller configured to determine a difference between the first image and the second image.
1 more element
An apparatus, comprising:
- a means for projecting a first image onto a first side of a display panel using visible light, a reflected portion of the first image being reflected from the first side of the display panel, a displayed portion of the first image being passed through the display panel and user-viewable on a second side of the display panel;
- a means for capturing a second image that comprises at least a portion of the reflected portion of the first image as well as light received from an object in proximity with a second side of the display panel;
- and
- a means for detecting a difference between the first image and the second image, wherein the difference is a representation of at least a portion of the object.
