It is intended to provide an image processing apparatus enabling an image processing for association of a standard image to a reference image using a reduced number of pixels without deteriorating accuracy for detecting a movement of a detection subject. A detection subject region setting unit obtains a picked-up image at a first time point as a standard image from time-series picked-up image data obtained by an image pickup unit and selects a plurality of correlation windows including an image region of the detection subject in the standard image with relative positions with respect to the standard point being identified. A movement detection unit obtains a picked-up image at a second time point that is different from the first time point as a reference image and detects a movement of the detection subject between the standard image and the reference image by calculating in the reference image a position of the standard point that minimizes a difference between a state of pixel values of the correlation windows of the standard image and a state of pixel values of correlation windows of the reference image.

A light irradiation device for irradiating light having a pattern onto a physical object, includes a pattern forming plate provided with a plurality of opening portions; a light irradiation unit for irradiating light towards the pattern forming plate; and a projection lens irradiated by the light irradiation unit, for integrally condensing light passed through an opening of the pattern forming plate and guiding the condensed light to the physical object, wherein the projection lens is arranged such that an image of the pattern forming plate is not focused onto the physical object, but is projected as a sinusoidal wave pattern.
