  • Patent number: 5784098
    Abstract: N lines of line-shaped light are projected onto the object by means of a measuring light projecting lens. The light carrying the image of the object is passed through the eyepiece lens 17 in an endoscope 6 and the auxiliary lens 30 in a measuring head 11 and split into two beamlets by a beam splitter 31, with one beamlet being focused at a position coinciding with the entrance end faces of measuring light's position detecting fibers 33(l) to 33(m). The line-shaped light images of the object thus formed in positions coinciding with the entrance end faces of measuring light's position detecting fibers 33(l) to 33(m) are scanned linearly by those linearly aligned fibers as they are oscillated and driven by a fiber scanner 36. The scanned line-shaped light images are then subjected to the necessary signal processing in a signal processor circuit 35 such as to measure the three-dimensional configuration of the object.

  • Patent number: 5374953
    Abstract: In an electronic endoscope apparatus each of the signals of a plurality of systems output from at least one solid state imaging device is judged by a signal monitoring device as to whether it is normal or not. On the basis of the judged result, the processing mode corresponding to each of the signals of the plurality of systems is changed and each signal is processed. If an abnormality occurs, an observed image with which the endoscope inspection can continue will be secured to be safe. Further, in the electronic endoscope apparatus, when the output signal from the solid state imaging device is judged to be abnormal, the amount of illuminating light will be attenuated, the danger by the excessive amount of illuminating light will be avoided and the safety of the person being monitored will be secured.

  • Patent number: 5113254
    Abstract: An endoscope apparatus is disclosed in which the horizontal transfer of the charge of a solid imaging device such as a CCD and the resetting for the detection of the charge are conducted by a common drive signal. The signal transmitted from the solid imaging device is caused to contain a feed-through period by making the drive signal to be served by a multi-valued level horizontal transfer signal exceeding a trinary value. Therefore, reset noise or the like can be eliminated by processing the output signal by using a correlated double sampling circuit or the like so that a video signal exhibiting a good S/N ratio can be obtained.
