<p>PROBLEM TO BE SOLVED: To more correctly detect movement of an object in a configuration for analyzing each image contained in a moving image.SOLUTION: An image analysis device 101 includes: a space range setting part 23 for setting one or more space ranges for each image contained in a moving image; a filter processing control part 31 for setting one or more frequency ranges for each image; a time domain filter processing part 34 for detecting a pixel whose characteristic amount changes with time by a frequency included in the frequency range among pixels included in each image; a feature point detection part 24 for detecting a feature point included in a space range in each image based on a time change of the characteristic amount of the pixel; and an object detection part 26 for detecting movement of the object based on the space range and the feature point. The space range setting part 23 can change the space range, the filter processing control part 31 can change the frequency range or the space range setting part 23 can change the space range, and the filter processing control part 31 can change the frequency range.</p> |
