Reducing crosstalk

A system comprising:

• a display;
• a camera;
• a computing device connected to the display and to the camera, the computing device having a control unit to
• cause the camera to capture a plurality of images of a local site through the display,
• cause the display to project a plurality of images of a remote site on the display, where each image is projected at least two successive times and where each successive image has a different intensity,
• cause the camera to capture a plurality of consecutive crosstalk images of the local site, where each crosstalk image includes an image of the local site combined with an image of the remote cite,
• determine whether a pixel value variation between two or more consecutive crosstalk images is affected by motion in the images of the local site included in the two or more consecutive crosstalk images, and
• perform crosstalk reduction on the two or more consecutive crosstalk images to produce a reconstructed image of the local user.

A non-transitory machine-readable storage medium encoded with instructions executable by a processor of a display-camera system, the machine-readable storage medium comprising:

• instructions to capture two or more mixed images of a local site, where a first mixed image includes a first image of the local site captured through a display blended with an image of a remote site projected on the display having a first intensity gain, and a second mixed image includes a second image of the local site captured through the display blended with the image projected on the display having a modulated intensity gain;
• instructions to determine whether a pixel value difference between the first and the second mixed images is affected by motion in the first and the second image of the local site;
• and
• instructions to select pixels from the mixed images that are not affected by motion and to perform crosstalk reduction to the selected pixels to create a reconstructed image of the local site.
