IMAGE PROCESSING APPARATUS

There is provided an image processing apparatus for performing a stable attention condition determination, regardless of the shape and surrounding environment of an object of interest and regardless that the object is unknown or known. The image processing apparatus comprises a direction detector, a displacement detector, and an attention condition determiner. The direction detector detects, from a certain image including a person image, the direction information in two body regions of a person represented by the person image. The displacement detector calculates, from the two direction information, a displacement ratio that is the ratio between the two direction displacements. The attention condition determiner determines, according to a first and a second displacement ratio, how much the person pays attention to a certain object. The first displacement ratio is calculated in the displacement detector by using first direction information detected by the direction detector from a first certain image including a first person image, and the second displacement ratio is calculated in the displacement detector by using second direction information detected by the direction detector from a second certain image including the first person image.
