Abstract: When a small block area enters a first two-dimensional code during a scan and features of the image within the area of a position in the first two-dimensional code coincide with a two-dimensional code, the block area is specified as containing a code and a recognition process is performed in the nearby areas. When the recognition of the two-dimensional code has been successful, the area of the first two-dimensional code is further extracted. When the extraction of the area of the first two-dimensional code has been successful, the scan using the small block area is further continued to search for a second two-dimensional code. With an already recognized entrance to the area of the first two-dimensional code, the area is skipped to continue the search. The second two-dimensional code is detected at a high speed by repeating the operation.

Abstract: What is disclosed is a system and method for encoding and decoding data in a color barcode pattern using dot orientation and color separability. The spectral (wavelength) characteristics of the CMY colorants, commonly used in digital printing, and those of RGB sensors are exploited to achieve high capacity data embedding rates in color barcodes. The present method embeds independent data in two different printer colorant channels using dot orientation modulation. In the print end, dots of two colorants occupy the same spatial region. At the detector end, by using the complementary sensor channels to estimate the colorant channels, data is recovered in each colorant channel. The method approximately doubles the capacity of encoding methods based upon a single colorant channel and enables embedding rates which match or exceed that of other hardcopy barcodes known in the arts. The method is robust against inter-separation misregistration with a small symbol error rate.

Abstract: Methods and systems are disclosed for processing of 2-D images of optical code symbols having information bearing characteristics in predominantly a single dimension (such as a linear barcode). In a preferred system, pixel summing or averaging is used to generate virtual scan lines for imaging of encoded symbols to improve the signal to noise ratio (SNR) of the resulting virtual scan lines. For example, pixel summing or averaging of an imaging array may be performed in a direction orthogonal to the virtual scan line direction in order to increase the SNR of the virtual scan line signal over what can be achieved with virtual scan lines created using a single image pixel for each virtual scan line pixel. The increased SNR offered by this technique of pixel summing or averaging of an imaging array may allow capture of images with reduced exposure time, enabling capture of images of objects moving at high speed without the necessity of high intensity light sources.
