IMAGE EVALUATION SYSTEM FOR SCANNING-TYPE ENDOSCOPE

摘要

In order to accurately evaluate the characteristics of acquired images without being affected by light that is reflected at the surface of a photographed object, the image evaluation system (1) for a scanning-type endoscope according to the present invention is provided with: a scanning-type endoscope (20) that is provided with a light-detecting unit (4) and with a fiber scanner unit (3) that is provided with an optical fiber (7) that guides illumination light from a light source (2) and has a tip (7a) from which the illumination light is emitted and with an actuator (9) that makes the tip (7a) of the optical fiber (7) oscillate and causes scanning to be performed with emitted illumination light; and a chart (T) that is for evaluating the characteristics of images acquired by the scanning-type endoscope (20). The light-detecting unit (4) and the tip of the optical fiber (7) are arranged so as to face with the chart (T) therebetween, and forward-scattered light that has been emitted from the tip of the optical fiber (7) and transmitted through the chart (T) is detected by the light-detecting unit (4).
