The camera in a mobile phone is no longer an additional accessory, but a necessary tool. You can use it to quickly save important information, photos of documents, and so on. This is especially true for students and school children who need to make copies of lessons, lectures, and seminars. The app has a built-in scanner with tools to correct the resulting image. Depending on the distribution of light and shadow, you can use the editor to increase sensitivity to dark or light areas, compensate for white balance, convert the drawing to black and white, and lighten dark areas. But the image itself is adjusted to the position of the document, taking into account the folds of the pages.
