PROBLEM TO BE SOLVED: To reduce a probability of wrongly associating a feature-point. SOLUTION: An image pickup device 100 comprises a video signal processing part 13 including: extracting a plurality of feature-points from any one reference image out of a plurality of images under control of a CPU71; a processing of tracking the extracted feature-point within the object images; calculating a temporary-projective-conversion-matrix H' between the reference image and the object image by using the predetermined number of feature-points out of the plurality of extracted feature-points; and setting the temporary-corresponding-point within the object image with feature-points other than the predetermined number of feature-points coordinate-converted by use of calculated temporary-projective-conversion-matrix H' as an initial position for tracking the feature-point.
