Abstract:
An addressable access image sensor array system for reading dataforms, comprising:a two-dimensional array of randomly accessible image sensor cells arranged to provide corresponding image data representative of an image area including an image of a dataform; an address circuit, operatively coupled to the two-dimensional array, for providing address signals to the two-dimensional array to access image data from selected image sensor cells included in the two-dimensional array; a judgment circuit for identifying image sensor cells in the two-dimensional array likely to provide image data representative of the dataform compared with other image sensor cells in the two-dimensional array likely to provide image data representative of portions of the image area other than the image of the dataform, and for providing address information to the address circuit to cause the image sensor cells likely to provide image data representative of the dataform to be selectively accessed for purposes of obtaining image data for decoding the dataform without requiring accessing the other image sensor cells; and an output for outputting the accessed image data.
