Disclosed are an image synthesis apparatus and an image synthesis method. According to the present invention, an image synthesis apparatus, for synthesizing a plurality of images to generate a synthesis image, selects for an image synthesis unit two or more images from among a plurality of images, and stores image information for the selected images, employs the stored image information to generate coordinate transformation parameters that are used to set a positional relationship for the selected images before these images are synthesized to obtain a single image, changes the generated coordinate transformation parameters by using as a reference a position location for an arbitrary image selected from among the plurality of images, provides the resultant coordinate transformation parameters as image synthesis information, and synthesizes the images in accordance with the image synthesis information. With this arrangement, even when there are many images to be synthesized, the positions of images can be precisely aligned without a large, permanent memory area being required for the storage of image data to be synthesized. Also, the characteristic of a synthesized image can be determined by employing as a reference the characteristic of an arbitrary image selected from among a plurality of images to be synthesized.

1. An image synthesis apparatus, for synthesizing a plurality of images in order to generate a synthesized image, comprising:(A) storage means for selecting from a plurality of images to be synthesized, as an image synthesis unit, two or more images, and for storing image information for the selected images; (B) coordinate transformation parameter generation means for employing said image information stored in said storage means to generate coordinate transformation parameters that are used to establish a positional relationship for said selected images before said selected images are synthesized to obtain a single image; (C) image synthesis information generation means for changing said plural coordinate transformation parameters, which are generated by said coordinate transformation parameter generation means, by using as a reference the position of any image of said plurality of images, and for furnishing the resultant coordinate transformation parameters as image synthesis information; (D) image synthesis processing means for synthesizing said plurality of images in accordance with said image synthesis information generated by said image synthesis information generation means; and (E) reference image designation means for designating as a reference an image selected from among said plurality of images, wherein said image synthesis information generation means, converts said coordinate transformation parameters, which are generated by said coordinate transformation parameter generation means, by employing, as a reference, a position for said image that is designated by said reference image designation means, and generates the obtained coordinate transformation parameters as image synthesis information.
