Methods systems and computer program products for motion initiated document capture

A computing device acquires a video of a tax document utilizing a video camera such as a webcam. The video is analyzed to detect a first motion of the tax document, such as sufficient shaking or movement of the tax document, satisfying first pre-determined criteria that results in the computing device being prompted or requested by the user to take an image of the tax document. After the first pre-determined criteria has been satisfied, the user is instructed to hold the tax document steady. Subsequent video frames are analyzed to detect a second motion or the tax document being sufficiently still or steady, in response to which an image of the tax document is acquired and processed to extract data of the tax document from the acquired image and populate corresponding fields of the electronic tax return.
