The invention provides an image recognition module, an electronic device, and an image recognition verification and scan correction method. The image recognition module comprises a display unit used to display a calibration image, an image scanning unit and a control unit, wherein the image scanning unit is used to scan the calibration image displayed on the display unit and generate a first scan image, the control unit is coupled with the display unit and the image scanning unit, scan image standard parameters of the image scanning unit are stored in the control unit in advance, the control unit receives the first scan image, and compares scan parameters of the first scan image with the scan image standard parameters, and the control unit corrects the image scanning unit according to a comparative result. The image recognition module uses the display unit to provide a stable image source so as to correct a scanning function and scanning quality of the image scanning unit, can replace color card correction, and can verify stability of an image recognition function. Additionally, the display unit can display the scan image whenever necessary.
Description
technical field [0001] The invention relates to the field of optical scanning, in particular to an image recognition module, an electronic device, an image recognition verification and a scanning correction method. Background technique [0002] At present, CIS image scanning technology is not only applied to scanners and photocopiers, but also gradually applied to equipment such as banknote counters, so as to realize the function of identifying currency / currency value and serial number of banknotes. Generally speaking, an image scanning unit, such as a scanner, performs calibration before scanning through a color card calibration method. The correction process is as follows: the image scanning unit scans the standard color card, and then compares the scanned data corresponding to the obtained scanned image with the standard data corresponding to the standard color card, and generates a special file for color difference correction for subsequent scanning correction. The colo...
