DocScanAI-文档扫描美化

DocScan AI — Feature Overview DocScan AI is an Android app for scanning and beautifying documents. It turns casual photos or gallery images of paper into flatter, clearer, easier-to-read digital pages. Processing is designed to happen primarily on your phone, so the core workflow does not require uploading images over the network. It fits everyday and study/work scenarios such as contracts, lecture notes, reading notes, receipts, ID copies, handwritten pages, and clippings. 1) Home: several ways to get started Take a photo: capture the page you want to process—useful for on-the-spot capture, counter receipts, or board notes. Choose from gallery: pick an existing photo—handy for archives, images saved from chat or email, or rescuing older shots. Sample documents: try the full flow with built-in examples before using your own images. The home screen summarizes what the app does and who it is for. You can also open More (or similar) for About information, depending on what your build shows. 2) Preview & processing: two depth levels After you open a preview, pick the path that matches your photo: Full scan path: detect document edges to find the paper outline; fine-tune the four corners so the crop matches the real edges; then run one-tap beautify to straighten perspective, reduce uneven shadows and lighting, cut noise, and boost overall clarity—closer to a flatbed-scanner look. Best when the shot is tilted or strongly perspective-distorted. Quick beautify path: if the document already fills the frame or you care more about clarity than cropping, skip edge detection and run one-tap beautify on the full image—fewer steps, faster to learn. Best when the shot is already roughly straight-on. Progress is shown in stages (outline/edges, perspective correction, shadow and tone cleanup, denoising, clarity enhancement) so long waits feel less opaque. When the pipeline finishes, a clear completion state helps you move on to compare or save. 3) Results: compare, filters, export On the results screen you can: Side-by-side compare: see before and after at once to judge brightness, flatness, and text readability—no guessing from memory. Filters: switch looks at the bottom—e.g. closer-to-original, enhanced, black & white, grayscale, high contrast—for text-heavy pages, mixed text and graphics, charts, or handwriting, and to prep for printing. Save to gallery: export what you see on screen to an image file in an easy-to-find album folder—share via messaging or email, print, or archive. Reselect: clear the current session and return home when you want a new image, so jobs do not get mixed up. 4) Privacy and connectivity Detection, correction, and beautification run mostly on-device. The app is not designed to upload your images to the cloud as part of its built-in flow, which helps with personal, financial, or sensitive business content. Core features remain usable on planes, subways, meeting rooms, or patchy networks without relying on a strong connection. 5) Language and practical tips The app supports multiple interface languages so people can work in a familiar language (exact availability depends on your device language and what your installed build offers). Results depend on angle, lighting, paper color and creases, clutter in the background, and glare. For important documents, use compare before saving, and go back to preview to adjust the crop or re-run processing if needed. If the subject is not a flat document, edge detection may be weak—try quick beautify or reshoot from a better angle.
