INFORMATION EXCHANGE DISPLAY USING COLOR SPACE ENCODED IMAGE

摘要

Embodiments of the present invention include systems, methods, and non-transitory computer program products for information exchange using color space encoded images. A color space encoded image can be displayed, for example on media such as posters, billboards, or paper, or on a display of a first device such as smartphone displays, palmtop displays, camera displays, tablet displays, or e-reader displays. A second device can acquire the displayed encoded image, for example by photographing the image. The second device can decode the color space encoded image or transfer the color space encoded image to a device that decodes the image.

主权项

1. A computer-implemented method for exchanging information between a first device and a second device, the method comprising:
receiving, at the first device, information for exchanging with the second device; creating a first image encoding the information by:
creating colored cells within a color space to provide an encoded representation of the received information in an image by processing the received information to obtain a stream of integers, each integer in the stream of integers corresponding to a color in the color space for a cell in the image; andcreating one or more additional cells adjoining the encoded image, the one or more additional cells for assisting in decoding the encoded image; displaying the first encoded image for a second device to decode; and in response to the displaying the first encoded image, receiving a second encoded image from the second device, the second encoded image having colored cells corresponding to a stream of integers encoding a response.
