Abstract
The image analysis deviceincludes a pixel selection unitwhich selects multiple pixels at a plurality of positions in one image among multiple images in which the same area is recorded, a dimension reduction unitwhich compresses a complex vector as an evaluation value when an evaluation function is optimized into a low-dimensional space, an expanding unitwhich returns a compression result by the dimension reduction unitto an original pixel space, and calculates a spatial correlation phase estimate; and an optimization unitwhich optimizes the evaluation function by bringing the evaluation value closer to the spatial correlation phase estimate and a pixel value at the position selected by the pixel selection unit
