Scanning Almighty King is a very useful mobile phone scanning software. You can learn about it. I've been using it. You can use image clipping and image enhancement algorithms to ensure that the scanned content is clear and readable, and you can enjoy the scanning speed at any time. Many people know that Scanning Almighty King has an OCR function to recognize characters, but it is usually single-sheet recognition. When the document is multi-page, it is still quite difficult to come out page by page. Use "continuous shooting"+"characters. In the "continuous shooting" function, all the documents that need to be recognized are photographed, converted into electronic manuscripts, and then click "Turn to Text" in more to recognize the text information in multiple documents. This method can get a document in one minute. What is manual input? Does not exist! If you want to know more, you may wish to search Baidu.
