A device and method for compensating for motion in image capture are provided. A processor ( 205 ) initiates partially concurrent scanning sweeps ( 208,209 ) across a digital image sensor ( 203 ) to obtain sets of digital values ( 210,211 ). At least a first set of digital values ( 210 ) and a second set of digital values ( 211 ) are stored in memory ( 206 ). An image construction module ( 213 ) compares ones of the first set of digital values ( 210 ) with ones of the second set of digital values ( 211 ) to estimate an amount of motion. The estimation may be accomplished by determining a moment between the first set of digital values ( 210 ) and the second set of digital values ( 211 ). Upon compensating for any motion, resulting digital values ( 412 ) are written to memory ( 206 ) as a compensated image. To improve an overall signal to noise ratio, noise reduction filters may also be applied to the first set of digital values ( 210 ), the second set of digital values ( 211 ), or combinations thereof.
