Further, a timing at which the image is imaged by the imaging unit (101) is recorded in an imaging timing recording unit (107). A weight coefficient for imaged image is calculated by a weight calculating unit (104) by utilizing the timing information obtained by the imaging timing recording unit (107). A high-resolution processing unit (106) generates a high-resolution image by using the weighted information of the image generated by the weight calculating unit (104).

In consideration of N-dimensional similarity, a multiparameter high precision concurrent estimation method and a multiparameter high precision concurrent estimation program in image subpixel matching, which can estimate a correspondence parameter between images precisely, concurrently, and stably with a small amount of computation at high speed. The method comprises the steps of: determining a sub-sampling position where the N-dimensional similarity value between images obtained at discrete positions is maximum or minimum on a line in parallel with a certain parameter axis, and determining an N-dimensional hyperplane that most approximates the determined sub-sampling position; determining N of the N-dimensional hyperplanes with respect to each parameter axis; determining an intersection point of N of the N-dimensional hyperplanes; and setting the intersection point as a sub-sampling grid estimation position for the correspondence parameter between images that gives a maximum value or a minimum value of N-dimensional similarity in the N-dimensional similarity space.
