Abstract: An endoscope system that illuminates an object and captures reflected light from the object includes a control processor. The control processor acquires an examination image and determines whether the examination image shows a swallowing state or a non-swallowing state. In addition, the control processor detects a high pixel value region from the examination image and determines that the examination image shows the swallowing state in a case in which an area of the high pixel value region is equal to or greater than a first threshold value. Further, the control processor performs grayscale conversion on the examination image to obtain a grayscale image and performs a binarization process for obtaining the high pixel value region in a case in which a density value of a pixel of the grayscale image is equal to or greater than a second threshold value.
