| 20120075444 | VIDEOENDOSCOPE WITH CONFIGURABLE TACTILE CONTROLS - The invention relates to a videoendoscope comprising a videoendoscopic probe comprising an inspection tube having a distal end housing an image sensor, and a control handle fixed to the proximal end of the inspection tube, the control handle comprising a display screen, and a video processing circuit connected to the image sensor and the display screen, the display screen being covered by a touch panel, and having a format such that its surface may be divided into an image display area occupying a whole height of the display screen and having a format corresponding to that of a photosensitive surface of the image sensor, and a lateral control key display area having a sufficient surface to display several control keys of sufficient size to be individually operated. | 03-29-2012 |
| 20120075443 | PROCESS OF REAL TIME ADJUSTMENT OF THE SENSITIVITY OF A VIDEO IMAGE SENSOR OF A VIDEOENDOSCOPIC PROBE - The invention relates to a method for adjusting the sensitivity of an image sensor, comprising: adjusting an integration duration of the image sensor between a minimum duration and an image frame duration, receiving from the image sensor a frame signal, amplifying the frame signal by applying an adjusted amplification gain between different minimum and maximum gain values, and for each frame of the frame signal, if an integration duration calculated as a function of an average value of the frame signal, is comprised between the minimum duration and a maximum duration equal to several times the frame duration, establishing the integration duration at the integration duration calculated and maintaining the amplification gain at a fixed value, otherwise maintaining the integration duration at the minimum or maximum duration and adjusting the amplification gain between the minimum and maximum values as a function of the average value. | 03-29-2012 |
| 20100238278 | Videoendoscopy system - The invention relates to a videoendoscopic system comprising a videoendoscopic equipment unit comprising an image sensor and a video processing circuit linked to the image sensor, and configured to supply synchronization signals and direct voltages, necessary to the operation of the video processing circuit and the image sensor, supply a standardized analog video signal directly usable by a video monitor from electrical signals supplied by the image sensor, on a low-impedance video link of a proximal multicore cable, receive a direct supply voltage through a supply link of the proximal multicore cable, and receive a control signal through a control link of the proximal multicore cable. | 09-23-2010 |
| 20100137685 | DEVIATED VIEWING RIGID VIDEOENDOSCOPE WITH ADJUSTABLE FOCUSING - The disclosure relates to a deviated viewing rigid videoendoscopic probe with adjustable focusing, comprising a rigid inspection tube and a control handle attached to the inspection tube, the inspection tube having a longitudinal axis and a distal part comprising an image capture device having a viewing axis different from the longitudinal axis, the control handle comprising a rotation control device for making the viewing axis turn around the longitudinal axis, and a focusing control device of the image capture device for longitudinally moving in the inspection tube a part of the image capture device, the rotation control device and the focusing control device being respectively configured to make the viewing axis turn and focus the image capture device, independently from one another. | 06-03-2010 |
| 20090160935 | METROLOGY DEVICE FOR VIDEOENDOSCOPIC PROBE - Image splitting device for videoendoscope, comprising an image splitting optical component to form on the sensitive surface of a video sensor housed in the distal end part of a videoendoscope a single composite image formed from two images of an observed target, viewed from two different angles; the image splitting optical component comprises two sections of identical convergent lenses, integrated into an opaque central element, maintaining the space between the two sections of lenses, each of the two sections of lenses are at least equal to a half-moon so that it is crossed by the optical axes of the lens. | 06-25-2009 |
| 20090116260 | LIGHTING DEVICE FOR VIDEOENDOSCOPE - A lighting device for videoendoscopic probe, comprising a light generator comprising a case wherein are mounted a light-emitting diode, a lighting endpiece attached to the end of the bundle of lighting fibers configured to adapt the surface of the proximal end of the bundle of lighting fibers to the light-emitting surface of the diode, and a connection part configured to be fixed on a handle of videoendoscopic probe, and to couple with the case, the case and the connection part being configured to maintain the lighting endpiece on the light-emitting surface. | 05-07-2009 |
