Detection of high-resolution, machine-readable tags using a mosaic image sensor

摘要

The imaging device 28 comprises a mosaic image sensor 38, which sensor generates a mosaic image comprising a matrix of pixels consisting of a plurality of interleaved sub-matrices comprising pixels of each color, each sub-matrix being a single. It is configured to capture and output. The processing circuit 32 is configured to process the pixels of each of the one or more sub-matrices separately from the pixels of the other sub-matrix to identify in the mosaic image a graphic tag 22 encoding a digital value in a machine-readable form. .
