    Abstract: Video frames of a document are captured. The edges of the document are identified from the frames as they appear within a field of view of a camera and a document rectangle for the document is tracked within the field of view. An area of the document determined from the frames is compared against the available area of the camera preview mode and a larger superimposed guiding rectangle is displayed as a guide within the camera preview mode. When a frame for the document is detected as having document edges that substantially fit within the guiding rectangle, the guiding rectangle is removed and an optimal image of the document is captured for subsequent downstream document image processing.

    Abstract: Video frames of a document are captured. A still image of the document is optimally automatically taken after the video frames have been recorded. The best image from the frames and the still image is determined. The best image is provided for OCR processing to derive document information represented in the best image for the document.

    Abstract: Video frames of a document are captured. A current orientation mode of a device having a camera is determined based on the video frames. An optimal orientation mode for capturing a document image is determined. Guided instructions assist in placing the device in the optimal orientation mode and when the document is centered in a lens of the camera, the document image is taken by the camera.
