Automatically Capturing and Cropping Image of Check from Video Sequence for Banking or other Computing Application

A method, comprising:

• receiving at a controller of a mobile computing device from a camera of the mobile computing device a video sequence having a plurality of frames of an image of a check;
• finding in bit values corresponding to pixels of a single frame of the plurality of frames of the video sequence both routing transit symbols that delineate a routing transit number on a MICR line of the check;
• determining a first distance from one of the routing transit symbols to the other of the routing transit symbols and a second distance from said one of the routing transit symbols to an edge of the check;
• calculating a ratio of the first distance to the second distance;
• comparing each digit of the routing transit number to templates of digits ranging from 0 to 9 to determine a value for said each digit by selecting a best matching image template therefore;
• and
• upon the ratio being within a predetermined acceptable range and the values for said each digit being determinable, capturing the image of the check from the single frame without user selection.
