Abstract: An endoscope apparatus includes a processor configured to carry out a reversal process on a side image of a subject picked up with an image pickup device, the reversal process reversing an order of a plurality of pixels located in the side image and arranged from a predetermined position in a radial direction, and cause a display apparatus to display a front image and the side image of the subject picked up with the image pickup device as a display image. The processor adjusts the timing at which the front image is displayed in such a way that the front image acquired simultaneously with the side image is displayed at a timing that accords with the timing at which the side image having undergone the reversal process is displayed on the display apparatus.

Abstract: 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.

Abstract: A diagnostic system, method, and a computer-readable storage medium for determining a severity of a gastric condition, such as gastric cancer, in a subject are disclosed. The diagnostic system includes a processor that can obtain various images of a stomach of the subject including wavelength images and generate difference images from the wavelength images. The processor can compare the subject images with reference images representative of different severity levels of gastric cancer, or can input the subject images into a learned model trained using the reference images stored in the database to extract a feature pattern corresponding to a severity of gastric cancer to diagnose the subject as having a particular severity level of gastric cancer.
