Information exchange 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 interactively 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, at the first device, an image encoding the information by:
creating colored cells within a color space to provide an encoded representation of the 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;partitioning the colored cells into a plurality of subimages of the image for assisting in decoding the encoded image, wherein each of the plurality of subimages is displayed individually; andcreating one or more additional cells adjoining the encoded image, the one or more additional cells for assisting in decoding the encoded image; displaying, at the first device, a first subimage of the plurality of subimages for the second device to decode and the one or more additional cells; and in response to displaying the first subimage, receiving (1) an encoded image including an acknowledgement that the first subimage was received and (2) a request to display a second subimage of the plurality of subimages.
