Outline of Final Research Achievements

In order to prevent overlooking of cancer in endoscopy, the fish-eye lens unit and the touch-sensitive sensor were developed. The fish-eye lens unit that has the size that can be inserted into the colon of cattle was fabricated. To correct images captured by the fisheye lens unit, the image processing method using the perspective transformation has been proposed. Its usefulness was revealed in experiments using a colon model. By attaching the touch-sensitive sensor to the endoscope tip, a load in the vertical direction acting on the scope tip could be detected.
