Abstract
The invention relates to a method for detecting a code (40), and a mobile station adapted to the method. In the method, the mobile station (50) is used to capture an image of the subject (40) and the image is analysed and decoded into a numerical form in the mobile station (50). According to the invention, before the decoding of the bar code in the mobile station the edges of the subject (40) are determined from a high-resolution image, in the case of a 2D code, the location of the corner point of the subject (49) are estimated on the basis of adaptive thresholding, and, in the case of a 2D code, a perspective transformation is formed.
