<p>Disclosed are a frame-skipping scanning and recognizing device and method, belonging to the field of computer peripheral equipment. The device comprises an optical sensor for taking images and a control module for processing the images and recognizing characters. The optical sensor continuously takes images of scanned characters so as to obtain an image frame sequence containing the scanned characters; the control module carries out downsampling on the image frame sequence, image frames subjected to downsampling are used as sampled frames, image frames not subjected to downsampling are used as skipping frames, and the number of the skipping frames adjacent to the sampled frames is more than zero; and all the sampled frames obtained after downsampling are spliced, the character recognition and storage are carried out on a panoramic image obtained through splicing, and character codes of the scanned characters are obtained. In the present invention, image frames in the image frame sequence acquired by the optical sensor are screened through the control module, the obtained image frames to be spliced are spliced according to overlapping contents, and the splicing speed of the whole image frame sequence is improved.</p> |
