Abstract
Abstract A data processing apparatus is provided with a part memory (17), which stores a plurality of part patterns of each of components which compose an object. A video signal of an image of the object, a montage of which is to be composed, is entered through an image-data input unit (14) to an image memory (15) to be stored therein. Image data stored in the image memory includes component-image data corresponding to the components. The component-image data corresponding to a component is read out in accordance with basic position data of the component stored in a basic position memory (16). The plurality of part patterns stored in the part memory (17) are compared with the component-image data in a pattern matching unit (18). The part patterns of the highest degree of resemblance are selected with respect to all the components, and are combined to be displayed on a display unit (19).
