Abstract:
1. A confocal scanning endoscope system, including a flexible insertion tube, the system comprising: a light source that emits light; a scanning unit disposed in the flexible insertion tube that deflects the light emitted by the light source so that the light scans on a subject in two dimensions with respect to the entire flexible insertion tube; an objective optical system that directs the light deflected by the scanning unit to the subject; an extraction unit that extracts only part of the light returning from a convergence point at which the light is converged by the objective optical system on an object side; an image formation unit configured to form an image based on the part of the light extracted by the extraction unit; and a display area adjustment unit configured to measure Encircled Energy of the part of the light extracted by the extraction unit and to adjust a display area of the image based on the measured Encircled Energy.
