Scanner Vault has in-built with automatic document detection. In the camera view, your document should be highlighted with a blue box upon detection.
If your document is not being detected:
Firstly, please check if you have set the camera to Auto mode. The top centre button on the camera page should say 'AUTO' instead of 'MANUAL'. Tap on the button to toggle it.
For optimal document detection, please ensure that:
- your entire document is within the camera frame
- your document is placed under a well-lit area
- there is sufficient color contrast between the background and the document color
- your document is placed on a smooth, uncluttered surface
If it still did not work, you can still manually capture the photo and adjust the cropping border after.
