<P>PROBLEM TO BE SOLVED: To provide an image recording method in which an automatic recording process is performed stably. <P>SOLUTION: The image recording method comprises: an initialization step of generating a prescribed number of search points in a specific region of an image; a filtering step of updating coordinates of a plurality of search points using a random number, comparing the characteristic value of the specific region with a characteristic value of each of the search points, after having updated in the image, assigning to the search points weights determined so as to be increased in proportion to a degree of similarity therebetween, screening the search points according to the weights, calculating a variance and a weighted average of the coordinates of the screened search points; and an image recording determination step of determining, on the basis of the variance and weighted average of the coordinates of the screened search points, and the tracking range, whether to record the image, and recording the image, if it is determined to record the image. <P>COPYRIGHT: (C)2010,JPO&INPIT |
