摘要： A plurality of bar-code candidate areas are calculated from scan data that is acquired by scanning a bar code. Feature data, which represents a specific feature, is calculated for each of the bar-code candidate areas. The bar-code candidate areas are evaluated based on their feature data to thereby determine a bar-code candidate area that has the highest probability of being a bar code. The specific feature includes any one or more of length of a differential waveform, average energy, and number of peaks in the differential waveform.

摘要： A signal obtained by optically scanning a bar code is subjected to differentiation to obtain differential data. Peak-to-peak distances are calculated from the differential data. When a peak-to-peak ΔTx distance is y times of a basic width, frequency f(x,y) will be, f(x,y)=y/ΔTx. A frequency map is prepared from the frequencies calculated. Transition routes in which one frequency each is selected. from each of the peak-to-peak distances, are formed. A transition route for which an error in frequencies is the least is taken as the most suitable transition route. An average of the frequencies included in the transition route is taken as a frequency f0 of the basic width.

摘要： 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.

摘要： A differentiation signal DF differentiated by a differentiation unit is inputted to a slice level generation unit and to comparators. A first peak-hold circuit and a voltage division circuit generate a slice level having a slice ratio SLR that is constant to a peak value VDF of the differentiation signal DF. A second peak-hold circuit generates a slice level the slice ratio SLR of which changes in accordance with the peak value VDF. The slice level generation unit outputs their synthetic slice level SLL, which is compared by the comparators with the level of the differentiation signal DF, outputting thereby binarized signals W-GATE and B-GATE. When the level of the differentiation signal DF is high, the slice level SLL approaches the peak value VDF. Therefore, noise components contained in the differentiation signal DF cannot exceed the slice level SLL. When the level of the differentiation signal DF is low, the slice level SLL has a constant ratio to the peak value VDF. Consequently, the peak value of the amplitude of the differentiation signal DF can be detected reliably.

摘要： A bar code reader for reading a bar code 30 composed of a plurality of white bars and a plurality of black bars, includes a generating unit 8 for generating bar width values respectively showing a width of the read bars, a judging unit 12 for judging based on the bar width values whether or not the read bar code satisfies a predetermined standard condition, and a converting unit 12 for converting the read bars into a plurality of bars in which a black-and-white-inverted bar is interposed between the conversion-target color bars. If the judging unit judges that the bar code does not satisfy the predetermined standard condition, the converting unit converts any one of the white and black bars constituting the bar code, and thereafter the judging unit makes a re-judgement. The bar code reader is capable of demodulating the bar code which has been abnormally read by presuming and compensating the bars read apparently as a single bar to a plurality of bars.
