An image processing apparatus includes a hardware processor. The hardware processor calculates a characteristic amount from each frame images of a moving image. The characteristic amount indicates change in a subject. The moving image is obtained by radiographing a dynamic state of the subject. The hardware processor extracts a frame image having the characteristic amount satisfying a predetermined condition, processes the extracted frame image by applying an image processing parameter to the extracted frame image prior to a remaining frame image, and causes a display to display the processed frame image.

System and method for diagnosing severity of gastritis

A diagnostic system, method, and a computer-readable storage medium for determining a severity of a gastric condition, such as gastritis, in a subject are disclosed. The diagnostic system includes a processor that obtains an image of a stomach of the subject collected by an endoscope. The processor can compare the subject image with reference normal and abnormal stomach images. If the subject image is abnormal, the processor can generate a subject abnormality image indicative of the differences between the subject image and the normal image. By comparing the generated subject abnormality image with reference abnormality images representative of different severity levels of gastritis, the processor can diagnose the subject as having a particular severity level of gastritis.
