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.

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.

A magnetically guidable medical device for use within the large intestine of a human body. A magnetically guidable guide wire is introduced into the rectum of a body of a patient and maneuvered through the colon under the influence of a controlled magnetic field to a desired location within the body of the patient. An external magnetic field applying means applies an external magnetic field effective to guide the magnetically guidable member within the body of the patient.

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.

A method for remotely controlling medical apparatuses and the method thereof are proposed. The medical apparatuses are used to take internal images of the human body, and have control command sets that comply with the DICOM specifications. In this method, a server is first built and connected to the medical apparatuses. A remote device is then built and connected to the server. Next, the remote device executes a remote control program to generate at least one DICOM control command, which is then sent to the server. The server then executes a communication program to perform control communications with the medical apparatuses. The medical apparatuses can thus be controlled to take images of the inside of human body for generating of digital image data complying with the DICOM specifications. The object of remote control for integrating medical apparatuses can thus be accomplished.

The invention aims at providing a measurement support device, an endoscope system, and a processor for an endoscope system capable of displaying an accurate indicator with a simple configuration. In a measurement support device related to one aspect of the invention, the coordinates of a spot, and coordinates of points indicating an actual size of a measurement target in a subject and indicating a circular marker distorted in accordance with distortion aberration of an imaging optical system are stored in association with each other in a storage unit, the coordinates of the points indicating the circular marker are acquired with reference to the storage unit on the basis of the measured coordinates of the spot, and the circular marker is displayed on the basis of the acquired coordinates. Thus, the distance measurement is unnecessary, the configuration is simple, and the processing load is low. Additionally, since the circular marker is displayed in the vicinity of the spot (for example, centering on a spot position), there is little deviation between the spot position and a marker position, the circular marker is accurate as an indicator. Additionally, since the indicator is not widely displayed, there is little processing load.
