binarizing the scanned image to obtain binarized frame image data;
and decoding the frame image data to obtain the tripod nine-code information represented by the tripod nine-code image of the scanning.
Further, in another embodiment, after scanning the tripod nine code pattern and obtaining the scanned image in this step, the tripod nine code information represented by the tripod nine code pattern scanned in this time is read from the scanned image, which may be executed in the following manner:
after scanning the tripod nine-code image each time and obtaining a scanning image, storing the scanning image obtained by scanning into an image queue;
extracting scanning images from the image queue according to the sequence from the first to the last of the preservation time;
binarizing the extracted scanning image to obtain binarized frame image data;

In this step, specifically, the information of the tripod nine code read out at this time may be displayed on the basis of keeping the information of the tripod nine code read out before being displayed in the scan page with the scan frame.
For example, the ding nine-code information may be displayed in the information display area 303 in a list manner.
Moreover, a delete button 304 may be disposed beside the ding nine-code information, so that when the displayed ding nine-code information is repeated, the user may perform delete operation by triggering the delete button 304; when the displayed tripod nine-code information is large in amount, the user can also display the hidden tripod nine-code information in the information display area 303 through a sliding operation.
And 105, stopping calling the camera to scan the tripod nine-code pattern after receiving the input reading stopping operation.
Specifically, after the operation of starting and stopping reading is detected, it may be determined that the camera needs to be stopped to be invoked for scanning the tripod nine-code image, for example, a user may end scanning the current tripod nine-code image by triggering a stop reading button in a scanning page.
