Abstract
The described implementations relate to enhancement images, such as in videoconferencing scenarios. One system includes a poriferous display screen having generally opposing front and back surfaces. This system also includes a camera positioned proximate to the back surface to capture an image through the poriferous display screen.
Claims20
At least one computer-readable storage media having instructions stored thereon that when executed by a computing device cause the computing device to perform acts, comprising:
- obtaining an image captured by a camera through a display screen, wherein some light that strikes the display screen is transmitted through the display screen and contributes to the image and some other light that simultaneously strikes the display screen is reflected;
- and,
- processing the image to accentuate an influence of the transmitted light and to reduce degradation of the image induced by the reflected light.
A system comprising:
- a display screen having a front surface and a back surface, the display screen configured to transmit light from the front surface through multiple pores of the display screen to the back surface and reflect other light from the front surface of the display screen;
- a camera configured to capture an image that includes the back surface of the display screen and the light transmitted through the multiple pores;
- and
- an image enhancement component configured to obtain the image captured by the camera and further configured to process the image to remove effects caused by the display screen.
1 more element
A system comprising:
- a processor configured to:
- defocus a camera positioned behind a display screen such that a focus distance of the camera is farther than a back surface of the display screen;
- cause the camera to capture an image at the focus distance, the image including the back surface of the display screen;
- and
- process the image by:
- accentuating an influence of light transmitted through the display screen from in front of the display screen, and
- reducing degradation of the image induced by other light reflected from a front surface of the display screen.
