Abstract: The value of the pixel at the same position of each of the training input image as well as a plurality of training feature images is inputted into the discrimination device, which learns in such a way as to reduce the error between the output value obtained from the discrimination device and the value of the pixel at the aforementioned pixel position in the training output image. At the time of enhancement processing, the feature image is produced from the image to be processed, and the values of the pixels of these images at the same position are inputted into the discrimination device, thereby outputting the enhanced image wherein the value outputted from this discrimination device is set as the value of the pixel at the aforementioned pixel position.

Abstract: An image displaying apparatus includes a memory, an image reader, an image processor, an image adder and a display. The memory stores a plurality of medical images including temporally sequential images of a common portion of a same patient taken at different points of time. The image reader reads out the plurality of medical images from the memory. The image processor processes at least two of the plurality of medical images read out from the memory according to registration information of the at least two of the plurality of medical images so as to obtain a processed image. The image adder adds one of the plurality of medical images read out from the memory to the processed image so as to obtain an addition image. And the display displays the addition image.

Abstract: An irradiation field region extracting apparatus for extracting an irradiation field region from a given radiation image. According to a first embodiment, image data corresponding to the radiation image is rotationally moved around a predetermined rotational center of the image data, with the image data having rectangular coordinates set thereon. A boundary line is extracted between the irradiation field region, where the radiation image is exposed, and an irradiation field stop region, where no radiation image is exposed, according to the image data rotationally moved by the rotational movement means. A parallel condition of the boundary line is detected wherein the boundary line is parallel to an axis of the image data, and rotation information data is generated which indicate an angle of a rotational movement of the boundary line from an original location to a location of the parallel condition and a distance between the predetermined rotational center and a given point on the boundary line.
