When you take a photo of an opened book, the pages of the book in the photo will be curved, and the text will also be bent and deformed. The "Correction" feature is designed to solve this problem - if the software recognizes that the paper in the photo is distorted, it will automatically straighten out the curved paper and the text. This function cannot 100% correct picture, if you think the processing effect is not good, please feel free to send us the picture at [email protected] so we can improve the system and help you in the future.
