Abstract:
1. A document image capture system, comprising: an input for receiving an image from a camera; at least one image buffer for storing data representing an image frame; an operating mode selector for receiving a selection between a live operating mode and a frozen operating mode; a motion detector coupled to said at least one image buffer for processing said image to detect motion between sequential frames of said image, wherein said image is a current live image when said motion detector detects said motion between said sequential frames and said image is a frozen image otherwise; an image processor coupled to said at least one image buffer for processing said image therein to extract document information from the image, said image processor processing said frozen image while in said frozen mode in accordance with a selected image processing operation and concurrently monitoring said current live image from said sequential frames; and a control device responsive to an output from said motion detector for controlling said image processor to begin processing when said motion detector detects that said image has become stationary after movement, wherein said live operating mode transitions to said frozen operating mode in response to said image in said sequential frames becoming frozen, and said frozen operating mode transitioning to the live operating mode in response to said motion detector detecting said motion between the frozen image and the current live image.
