Method of compressing a dynamic range for a radiation image

Image Number 10 for United States Patent #5471987.

A dynamic range compression method for a radiation image for obtaining processed image signal carrying an image having a dynamic range that is narrower than that of the original image, by processing original image signal representing an original image based on radiation image information transmitted through an object. The method is for obtaining unsharp mask signal by averaging the original image signal in a predetermined mask area containing each pixel point corresponding to each pixel point and for correcting original image signal by providing a correction value that is a function of the unsharp mask signal to obtain a processed image signal. Weighting is applied corresponding to an absolute value of a signal different between a central pixel and a peripheral pixel both within a mask area in the averaging process for obtaining the unsharp mask signal.
