Patent number: 6827268Abstract: A still image of a moving object is restored from portions including the object in an image by using a movement distance of the object during an exposure time and the difference value between output values of adjacent pixels, the movement distance being calculated as a number of pixels. Therefore, especially in cases where a moving bar code is imaged, even if the image of the bar code is blurred as a result of the movement of the bar code during imaging, a still image of the bar code in which the outlines of the black portions and white portions of the bar code are clear can be obtained. Accordingly, bar code information can be read out from the imaged bar code.Type: GrantFiled: October 5, 2001Date of Patent: December 7, 2004Assignee: Fujitsu LimitedInventors: Mitsuharu Ishii, Toshitaka Aoki, Isao Iwaguchi, Hiroaki Kawai, Kozo Yamazaki, Mitsuo Watanabe

Patent number: 6565004Abstract: A scanning apparatus and an optical reading apparatus according to the invention is featured in obtaining reading result corresponding to a plurality of bar code symbols by processing, as predetermined, demodulated data corresponding to signal light from the bar code labels and optically readable symbols. Such a scanning apparatus extracts sets of consecutive data, which consecutively indicate all bar code symbols constituting the bar code symbols, from the demodulated data, and further chooses only sets of consecutive data that are different from each other, whereby reading data corresponding to a plurality of bar code symbols are collectively obtained. Furthermore, the optical reading apparatus collectively obtains the reading result corresponding to a plurality of symbols by extracting data that meets predetermined conditions and are different from each other, from the data obtained by demodulation.Type: GrantFiled: January 23, 2001Date of Patent: May 20, 2003Assignee: Fujitsu LimitedInventors: Mitsuharu Ishii, Toshitaka Aoki
