When we use mobile phones to take photos of documents, affected by light, the photos always have gray or black background color, which leads to unclear text display and poor printing effect when printing. In response to this problem, the following is a very practical method to remove the background color of scanned documents in batches, so that the text can be displayed more clearly, the printing effect can be improved, and the documents can be conveniently sorted and archived.
It is very common in the work to turn scanned documents with shadows and black and gray background into clean black characters on white background.
For example, the contracts, test papers, homework and other documents we take with our mobile phones have shadows and are not clear, which not only affects reading, but also appears very unprofessional when sent to customers. In addition, if you want to print the paper documents taken by mobile phones, these shadows and background colors also greatly affect the printing effect and are not convenient for archiving.
In this case, we need to change the document photo or scanned document into a clean white background and black character effect, remove the black background of the paper, and keep the text clearly.
This skill is very practical in daily study, life and work, and can solve many problems after mastering it. Therefore, the following is to teach you the specific method of operation. Not only can the text in the scanned photos become clear, but also tens of thousands of pictures can be processed at one time, with efficient automatic batch processing, avoiding the tedious manual operation and saving time and effort!
