An image-reading device is provided with a first detection unit for detecting that the front side of a cover is within a first distance to ca copy holder, a second detection unit for detecting that an opening/closing support part is within a second distance to the copy holder, and a control unit. The contorl unit: acquires first detection information due to the first detection unit and second detection information due to the second detection unit, respectively; and identifies, on the basis of the first detection information and the second detection information, whether a copy set in place has a thickness equal to or greater than a fixed value.

A compact illuminator for a direct part marking (DPM) scanner is provided to perform dual-field, multi-color, multi-directional, multi-distance illumination functions. The illuminator can selectively provide dark field and bright field illumination with broad spectrum white or narrow band color, in combination with directions for near contact distance as well as far distance barcode readings. Specifically, illuminator includes a front edge illuminator with customized LED optics, a dome diffuser, an LED board assembly, and a reflective sleeve surrounding the dome diffuser. The board assembly can further include an alternative on/off plural point source bright field spot illuminating system. A method for scanning DPM indicia focuses on generating illumination light using an illumination assembly, illuminating the DPM indicia, detecting reflected and/or scattered light, and capturing under different illumination conditions and combining at least two consecutive images of the DPM indicia, followed by processing and decoding the obtained image.

An image scanning method applied in an image scanning device capable of scanning a card. Record background values at the time of a card being without being in a scanning channel, and the background values recorded at the time of the card being without being in the scanning channel are regarded as preset values. Before the card is scanned, check whether the background values in the scanning channel conform to the preset values. Drive the card to move a distance Y. Check whether the background values in the scanning channel conform to the preset values. Preset a preset movement distance, check whether a movement distance of the card or a distance of accumulated movements of the card exceeds the preset movement distance. Display that the card is stuck. Stop checking and proceeding with an image calibration. Start scanning the card. Complete scanning the card and withdraw the card.

An image capture and output method comprises steps of providing an image capture device, continuously capturing a plurality of line images from an initial position and recording a position information corresponded to each line image, calculating the difference between the position information of the first line image and the initial position and the differences between the position information of each of the rest line images and a former one of the line image to obtain a fill information, filling each line image into an image buffer according to the fill information, and outputting the image buffer as a product image. Therefore, the deformation issue is effectively solved, the storage memory is saved, and the manufacturing cost is lowered.

Methods, systems, and devices for adjusting a scanning status are provided. In one example method, a mobile terminal can determine whether a target object is a preset target type. If so, a reference scan parameter is determined corresponding to the preset target type, and a real-time scan parameter is obtained that is used when the mobile terminal performs scanning around the target object. A determination is made as to whether the real-time scan parameter conforms to the reference scan parameter. If it does not, a prompt message used to prompt a user to adjust a scanning status corresponding to a current scan parameter is generated.
