PROBLEM TO BE SOLVED: To restore the camera motion and object shape with high accuracy being robust against noise. SOLUTION: From the temporal movement of a feature point measured from a time series image, in a recursive perspective projection type factor decomposition method, an information reference amount is calculated, thereby eliminating noise and setting a conditional formula required for restoring the camera motion. Thus, the camera motion to be robust to noise is restored, and simultaneously an object shape is restored. In the calculation recursively repeating the perspective projection type factor decomposition method, decomposition superior to the camera motion or object shape exists. So the superioty is detected, and in order to restore the camera motion and the object shape at the same time and with high accuracy, the superior one of the camera motion or the object shape is bounded and further recursive perspective projection type factor decomposition method is repeated.
