Abstract: PURPOSE:To set correctly a range wherein correlation is taken, to determine a correct depth and to reduce the amount of correlation computation by determining the result of the correlation computation by a sphere determinator and by changing the dimensions and position of the sphere of the correlation computation when a correlation value is not sufficient. CONSTITUTION:Image signals of a stereopair inputted are stored in an image memory 1, and before correlation computation is executed, band limitation is conducted by a filter 2 in accordance with the dimensions of a sphere of the correlation computation. When the sphere is wide, on the occasion, the band limitation is conducted sufficiently, and when the sphere is narrow, the band limitation is reduced, the amount of the correlation computation being lessened. Next, a place wherein correlation is the maximum is determined by a correlation computation unit 3 from the image signals subjected to the band limitation by the filter 2. Then, the result of the correlation computation is determined by a computation sphere determinator 4, and when a correlation value is not sufficient, the dimensions and position of the sphere of the correlation computation are changed. Thereby the sphere wherein the correlation computation is executed correctly is determined and the correlation value can be computed. Accordingly, the relation of correspondence between images of the stereopair is determined correctly and a correct depth can be determined.
