    摘要: Imaging apparatus (28) includes a mosaic image sensor (38), which is configured to capture and output a mosaic image comprising a matrix of pixels that is made up of multiple interleaved sub-matrices, each sub-matrix containing the pixels of a single respective color. Processing circuitry (32) is configured to process the pixels in each of one or more of the sub-matrices separately from the pixels in the other sub-matrices in order to identify in the mosaic image a graphical tag (22) that encodes a digital value in a machine-readable form.

    摘要: A method for information display includes specifying information pertaining to a target location and encoding the specified information in a machine-readable symbol (22, 60) comprising a set of three or more color elements (40), which have different, respective colors that encode a first part of the information and are contained within a non-rectangular border (44), which has a shape characteristic that encodes a second part of the information. The symbol is positioned in the target location.
