ABSTRACT:
An image signal representing radiation images is detected from a recording medium on which the radiation images have been recorded in a subdivision pattern. The whole image recording area of the recording medium is divided into four regions which have the same shape and the same size and which are vertically and horizontally adjacent to one another. Calculations are made from the image signal in order to find characteristic amounts which represent resemblances in image between the divided regions which are vertically adjacent to each other and between the divided regions which are horizontally adjacent to each other. The subdivision pattern of the radiation images is determined by judging that the divided regions which are found as resembling each other in image are the subdivisions into which the whole recording area of the recording medium was divided when the radiation images were recorded thereon.
