Abstract:
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.
