1. An image processing system, comprising: an image receiver to receive a first image sequence composed of first partial images captured at a plurality of time points, and a second image sequence composed of second partial images captured at the plurality of time points, each one of the first partial images and each corresponding one of the second partial images being captured at substantially a same time point; and processing circuitry to detect a stitching position of each one of the first partial images and each corresponding one of the second partial images captured at substantially the same time point for the plurality of time points, correct information of the stitching position at each time point of the plurality of time points based on information of the detected stitching position at the time point and at another time point of the plurality of time points, and synthesize each one of the first partial images and each corresponding one of the second partial images captured at substantially the same time point based on the corrected stitching position information for the plurality of first and second partial images to generate a plurality of synthesis images.
