  • Patent number: 6902527
    Abstract: An endoscope 2 has a CCD 9 incorporated in the distal part of an insertion unit 6 thereof. The sensitivity of the CCD 9 can be varied by applying a plurality of pulsating driving signals so as to change an electron multiplication rate. The endoscope 2 is connected to a processor 3 so that it can be disconnected freely. Information representing a type of endoscope stored in advance in a ROM 48 is transmitted to a controller 21 incorporated in the processor 3. The control means 21 uses a CCD sensitivity control means 12 to control the sensitivity of the CCD 9 according to the type of connected endoscope 2. In addition, an automatic gain control circuit supplementarily amplifies a signal output from the CCD 9 so that the level of the signal becomes a predetermined level. Consequently, a view image of proper brightness can be produced irrespective of the type of endoscope 2.

  • Patent number: 6231539
    Abstract: A backflow prevention structure, which is to be connected to a liquid medicine inlet of a liquid medicine injection device for injecting a liquid medicine in a liquid medicine retaining vessel of the liquid medicine injection device into a body part, includes a backflow prevention valve element provided at the liquid medicine inlet for preventing backflow of the liquid medicine from the liquid medicine retaining vessel. The backflow prevention valve element has a beaklike nonreturn valve and an annular valve and the liquid medicine is introduced into the liquid medicine retaining vessel through the beaklike nonreturn valve, and the liquid medicine in the liquid medicine retaining vessel is allowed to flow in a reverse direction via the annular valve when a negative pressure is produced on one side of the backflow prevention valve element opposite to the liquid medicine retaining vessel.

  • Patent number: 5872899
    Abstract: A ROM stores density conversion tables appropriate for a present apparatus to execute recording and standard density conversion tables. As a command is entered on a control panel, a CPU sets the optimum density conversion table in a RAM and again converts image data of 256 levels of gradation for a density adjustment. Resultant image data undergoes false halftone processing in an error diffusion circuit and is transmitted to the present apparatus or a destination recorder. When the record characteristic of the destination recorder is unknown, the standard density conversion table is used, so that no large difference occurs for recording.

  • Patent number: 5585840
    Abstract: A detection signal of an image pickup device is inputted to a gate circuit to open the gate circuit by a gate signal from a drive-signal generating circuit during a period of time of a phase regulating signal section of a drive signal, to thereby output the detection signal during the period of time, to a reference reset generating circuit. The reference reset generating circuit generates a reference reset signal on the basis of the detection signal during a period of time of the inputted phase regulation signal section. The reference reset signal and a basic clock signal are inputted to a timing-pulse generating circuit for generating various kinds of timing pulses which are used in an image-pickup-signal processing circuit for processing in signal the image pickup signal.

  • Patent number: 5408263
    Abstract: An electronic endoscope apparatus has an arrangement that its discrimination circuit discriminates the type or the operational state of the light source in accordance with a discrimination signal transmitted from a discrimination signal generator, and in accordance with the result of the discrimination, the processing operation to be performed by its video signal processing circuit is changed over to correspond to the difference in the type or the operational state of the light source. The video signal processing circuit performs a proper signal processing operation to correspond to the difference in the type of the light source to prevent deterioration in the image quality. The electronic endoscope apparatus is structured so that a different type light source can be adaptably connected to it.

  • Patent number: 5408335
    Abstract: An image signal sent from an image sensor is input to the inverting terminal of a differential amplifier. An A/D converter converts an output of the differential amplifier to digital output data. A comparison circuit compares the digital output data with a reference value in a dummy bit period to produce a comparison result, for instance, a difference between the digital output data and the reference value. Based on the comparison result, a correction value setting circuit modifies a correction value so that a DC offset becomes closer to the reference value. For example, the correction value setting circuit adds the difference obtained by the comparison circuit to the correction value. A D/A converter converts the modified correction data to an analog voltage, which is input to the noninverting terminal of the differential amplifier.
