Abstract:
1. A video signal display device for displaying a moving image that is made from a plurality of images, comprising: an attraction point determination portion operable to determine an attraction point in a current image, which is one of the images that make up the moving image; a corrected center position storage portion operable to hold coordinates of a corrected center point of a previous image, which is the image that is previous to the current image; a corrected center position determination portion operable to determine a corrected center point in the current image, based on the attraction point that is determined by the attraction point determination portion and the corrected center point of the previous image that is held in the corrected center position storage portion; a correction parameter creation portion operable to create a correction parameter based on the corrected center point of the current image; a correction portion operable to correct the current image based on the correction parameter; and a display portion operable to display the image that is obtained by correction by the correction portion; wherein the corrected center position determination portion sets a point on the image that is between the attraction point and the corrected center point of the previous image, and whose distance on the image from the corrected center point of the previous image is equal to or less than a limit value, as the corrected center point of the current image; and wherein the corrected center position storage portion stores the coordinates of the corrected center point of the current image that has been determined by the corrected center position determination portion.
