摘要： A signal output board includes: a drive signal generation section configured to generate a drive signal for a CCD; an inverse signal generation section configured to generate an inverse signal by inverting a phase of the drive signal from the drive signal generation section; a first signal transmission line portion configured to transmit the drive signal from the drive signal generation section; a second signal transmission line portion configured to transmit the inverse signal from the inverse signal generation section, at least part of the second signal transmission line portion being arranged in parallel to and adjacent to the first signal transmission line portion; an output end portion configured to output the drive signal transmitted by the first signal transmission line portion, to the outside; and an equivalent load section including a load equivalent to a transmission path for the drive signal from the output end portion to the electronic device, the equivalent load section being connected to an end portion of the second signal transmission line portion.

摘要： A CCD driver circuit adjusts and supplies pulse-type signals to a CCD in order to adjust the sensitivity of the CCD. A metering circuit meters a signal output from the CCD. A sensitivity control circuit controls the sensitivity of the CCD by controlling the sensitivity multiplication factor of the CCD based on a metering result by the metering circuit. A metering correcting circuit corrects a metering result from the metering circuit based on a charge multiplication factor from the sensitivity control circuit. An aperture control circuit controls an aperture based on a metering signal corrected by the metering correcting circuit. Thus, an image of an object of which strength of light largely varies can be obtained as an image under a proper dimming state.

摘要： An endoscope includes a solid image-pickup device having an image area and an optical black area for performing photoelectric conversion and including a function of varying an amplification ratio, and a first signal clamp circuit clamps the analog output signal that is outputted from the solid image-pickup device to adjust into an input range of the analog signal processing circuit with an analog reference signal which is unaffected by a defective pixel in the optical black area. The clamped signal is processed to extract signal components which are photoelectrically converted by the analog signal processing circuit by the image area. The output signal from the analog signal processing circuit clamps the signal in the optical black area by using output signals of at least the number of pixels larger than the number of pixels in a horizontal direction in the optical black area by the second signal clamp circuit.
