PROBLEM TO BE SOLVED: To obtain more correct base signals.SOLUTION: A learning unit learns a plurality of base images as base signals such that still images of brightness images for learning as signals are represented by a linear operation of a plurality of base images as base signals for which base image coefficients become sparse, by using cost functions including terms showing correlation between base image coefficients. This technique can be applied to, for example, a learning device that learns base signals in sparse coding.
