ABSTRACT:
The present invention discloses an image composing apparatus comprising a reference block setting circuit for setting a search area having a stored arbitrary size in an overlap region of composed image data which has been picked up, for setting a first reference block at a suitable position in the area, depending on determination as to correlation performed by an optimal average density calculation circuit, for extracting a reference point, for extending a search line from the reference point toward a lower portion, for setting a second reference block at a position on the search line, which has correlation, for extracting a reference point, and for obtaining reference points, a displacement amount detection circuit for obtaining displacement amounts R and S from the reference points, an interpolation circuit for interpolating images, and a composing circuit for performing image composing.
