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： In the present invention, an abnormality determination circuit outputs an abnormality determination signal when determining an abnormal pixel, captures images of a synchronization memory F, a synchronization memory G, and a synchronization memory R at the time in a temporary memory. Also, an abnormality position display circuit is controlled to display, in a superimposing manner, a mark indicating a position with the abnormal pixel on the images captured in the temporary memory. Still image data of a normal image marked in the superimposing manner and stored in the temporary memory is outputted to a D/A conversion circuit, and thus displayed in a thumbnail form on a monitor. This allows an area suspected of having abnormal tissue to be easily and reliably identified on a normal color endoscopic image.
