Claim One:
1. A method for reading a barcode by an optical reader arranged to capture at a determined sampling frequency a series of partial images of the barcode by a sensor having at least one line of pixels, wherein the barcode includes a plurality of bars of variable widths that define a bit sequence, and wherein this method comprises: A) moving the sensor along the barcode parallel to said line of pixels at any speed of movement less than a maximum speed, wherein this maximum speed is defined so that a shift between two consecutive partial images is less than a width (X un ) of an image of a bar unit of said barcode; B) a length of said line of pixels is less than a length of a theoretical image of the barcode at the sensor and more than the width of the image of a bar of maximum width on the sensor; C) for each partial image captured by the sensor, determining a logical value by a level of light intensity received by at least one pixel located more or less in a center of said line of pixels; D) for each partial image captured by the sensor, measuring the width of the bar corresponding to said logical value, when this is defined, when this bar is incorporated completely into this partial image; E) when a same logical value is obtained for two consecutive partial images in the determining the logical value, retaining a single logical value and the width of the corresponding bar to establish said bit sequence.
