Problems solved by technology
[0002] Existing business card recognition systems or optical character recognition systems (whether used on mobile communication terminals or on computers) perform optical character recognition methods, generally first using image capture equipment to obtain images, such as using The camera scans the image, scans the image with a scanner on the computer, or they directly obtain network downloads, pictures, etc., and then use optical character recognition software or hardware to recognize and output all the text in the image, so the system processing speed is quite slow
Moreover, when the operator gets the output text, he is disturbed by many irrelevant text information that he is not interested in.
The operator also needs to perform operations such as deleting the information, which reduces the efficiency of use

Embodiment Construction
[0022] Hereinafter, the present invention will be further described in detail with reference to the drawings and specific embodiments of the specification.
[0023] Referring to Fig. 1, the method for performing optical character recognition on a display operation terminal provided by the present invention can be applied to products such as computers, mobile phones, PDAs, etc., to recognize text information on advertisement columns, license plate numbers, and communication information on business cards. Wait. Its essence is to combine the operation auxiliary positioning of the display operation terminal with the algorithm of the optical character recognition system. It specifically includes the following steps:
[0024] Step 1. Obtain an image for optical character recognition and display it on the display of the display operation terminal.
[0025] For example, a computer can obtain an image for optical character recognition through a scanner, digital video camera or other means,...

The present invention discloses a method for making optical character recognition by using display operation terminal. Said method includes the following steps: firstly, obtaining image having need of making optical character recognition and displaying it on the display device of display operation terminal; analyzing contents of said image and separating its literal contents into several literal region blocks; then selecting literal region block having need of making optical character recognition on the display operation terminal; finally, making optical character recognition. Said literal region block can be limited and displayed by adopting identification character.
Description
Technical field [0001] The invention relates to a method for a display operation terminal to automatically recognize characters in an image, in particular to a method for a display operation terminal to perform optical character recognition. technical background [0002] The existing business card recognition system or optical character recognition system (whether it is used on a mobile communication terminal or a computer) for optical character recognition generally uses image capture equipment to obtain images, such as on mobile communication terminals. The camera scans the image, and the scanner scans the image on the computer, or they directly obtain network downloads, pictures, etc., and then use optical character recognition software or hardware to recognize and output all the characters in the image, so the system processing speed is quite slow. Moreover, the operator is disturbed by many irrelevant text information that he is not interested in while getting the output tex...
