Mobile device capable of offline and online synchronous image identifying, an image identifying system, and a storage medium for the same

An image identifying system for offline and online synchronous operations, comprising:

• a mobile device, comprising:
• an image capturing unit for retrieving frames of a recognition target;
• a display monitor for displaying a result of image recognition;
• and
• a processor, determining whether the mobile device is operatively connected to Internet, and performing offline image recognition on the frames and displaying a result of the offline image recognition on the display monitor when the mobile device is not operatively connected to the Internet;
• and
• a recognition server, receiving the frames from the mobile device when the mobile device is operatively connected to the Internet, performing online image recognition on the received frames which is synchronized to the offline image recognition, and replying a result of online image recognition to the mobile device;
• wherein, the mobile device displays the result of online image recognition on the display monitor when the result of online image recognition has a recognition value higher than a recognition value of the result of offline image recognition, else the result of offline image recognition is displayed.

A storage medium for storing an application, wherein when the application is executed by a processor of a mobile device, the following steps are performed:

• a) retrieving frames of a recognition target via an image capturing unit of the mobile device;
• b) determining whether the mobile device is operatively connected to Internet;
• c) when the mobile device is not operatively connected to Internet, the mobile device performs offline image recognition on the frames and displaying a result of the offline image recognition on the mobile device;
• d) when the mobile device is operatively connected to Internet, the frames are sent to a recognition server via Internet;
• e) following step d, the mobile device performing the offline image recognition on the frames and displaying the result of the offline image recognition on the mobile device;
• f) following step d, the recognition server performing online image recognition on the frames synchronously with the mobile device;
• g) the mobile device receiving a result of the online image recognition from the recognition server;
• and
• h) displaying the result of the online image recognition when the result of the online image recognition has a recognition value higher than a recognition value of the result of the offline image recognition.
