Claim One:
1. An image position recognition apparatus, comprising: an image signal acquirer configured to acquire, from an image capture apparatus, a red image signal, a blue image signal, and a green image signal obtained by capturing a picture from an image display apparatus; a position recognition unit configured to use the red image signal, the blue image signal, and the green image signal acquired by the image signal acquirer as a basis for recognizing a position in a captured picture corresponding to a given region among respective regions obtained by dividing the picture from the image display apparatus into a plurality of regions; and a correction data setting unit configured such that, when the position recognition unit recognizes the position in the captured picture corresponding to the given region of the picture from the image display apparatus, data for emphasizing the given region is set as the correction data corresponding to the given region of the red image signal, the blue image signal, and the green image signal in the image display apparatus, wherein the position recognition unit recognizes positions in a captured picture corresponding to regions that correspond to corners of the picture portion captured by the image capture apparatus, and wherein the position recognition unit recognizes the position in the captured picture corresponding to a portion that corresponds to a respective corner of the picture portion captured by the image capture apparatus, the recognition being achieved by conducting a first process to recognize the position in the captured picture corresponding to a first process region among those of the picture from the image display apparatus that corresponds to the respective corner, and if the position in the captured picture corresponding to the first process region is not recognized in the first process, conducting a second process to recognize the position in the captured picture corresponding to a second process region which is shifted away from the first process region and towards a center of the picture and, if the position in the captured picture corresponding to the second process region is recognized, to move the position in the captured picture corresponding to the second process region to a corner of the picture which is actually displayed.
