A correcting portion of an endoscope subjects a reference image to a magnification correction process so that the distance between a first mark and a second mark within the reference image is substantially equal to the distance between a first mark and a second mark within a comparative image. Next, the corrected reference image is subjected to a rotation correction process so that the orientation of the second mark with respect to the first mark within the reference image is substantially equal to the orientation of the second mark with respect to the first mark image within the comparison image. Further, the corrected reference image is subjected to a brightness distribution correction process so that the brightness distribution thereof becomes equal to that of the comparison image. The display state of the reference image and comparison image are made substantially equal, comparative diagnosis is facilitated, and diagnostic efficiency is improved.

In a method to control the movement of an endoscopy capsule in a hollow organ of a patient using a magnet system, a movement signal of the endoscopy capsule in the hollow organ is detected, that represents the time curve of the spatial position. The movement signal is evaluated to identify a periodic signal component thereof, and the frequency of this periodic signal component is identified. The magnet system is operated to exert a force on the endoscopy capsule in the hollow organ that is periodic with the frequency of the periodic signal component, and that is directed opposite to the movement signal.

Surgical correction of presbyopia and hyperopia by a circularly distributed assembly of mini-bridges implanted between the interior surfaces of the ciliary muscle and the exterior surface of the lens capsule, for augmenting the transmission of the contraction force of the ciliary muscle/zonule assembly to the lens capsule. The lens is symmetrically squeezed by mini-bridges acting in concert with the ciliary muscle thus changing the curvature of the lens. The mini-bridges are composite synthetic muscles comprising either passive biocompatible mini-bridges made with polymeric gels, silicone polymers or a composite, electromagnetically or mechanically deployable mini-bridges, inflatable balloons or synthetic muscles. The surgical procedure comprises using a ciliary muscle relaxant to stretch the lens/zonules/ciliary muscle assembly. An ultrasonic biomicroscope (UBM) is then used to enable the surgeon to see the area for implantation and the mini-bridges and thus perform endoscopic or incisional surgery to implant the mini-bridges in and around zonular cavities.

In the processor device connected to the endoscope, the imaging signal transmitted in serial from an imaging chip of the endoscope is converted by an S/P converter to parallel data, and is then decoded by an 8B10B decoder. Pixel data (eight bits) for each pixel is converted by an 8B10B encoder of the imaging chip to word data with ten bits being taken as one word for serial transmission. In the processor device, the fact that a deviation occurs in timing of word synchronization for delimiting serial data into word data due to an influence of noise or the like is detected from a decode error in the 8B10B decoder, and recovery is made by shifting the timing of word synchronization.
