摘要： To provide a timing generator which generates a first reference signal at a standard speed of approximately 14 MHz and a second reference signal operating at approximately 28 MHz which is double the standard speed and forms a moving image based on the first reference signal, reads, when a freeze switch is operated, an image pickup signal based on the second reference signal operating at the double speed and writes this signal into the memory 36 at the same speed. Then, by reading this still image signal from the memory at the standard speed, the still image is displayed on the monitor. Thereby, the need for setting a conventional light shielding period can be eliminated.

摘要： In a first signal suppressing process, in cases where a signal level of a certain color signal among color signals obtained from an image sensing operation is higher than a predetermined signal level, the certain color signal is suppressed. An image sensing operation with a comparatively large exposure quantity and an image sensing operation with a comparatively small exposure quantity are performed alternately. It is detected that suppression of a certain color signal is performed in the first signal suppressing process when the image sensing operation with a comparatively large exposure quantity is performed. A calculation is made to find composition ratios of the color signals, which are obtained from the image sensing operation with a comparatively small exposure quantity. A second signal suppressing process is performed for suppressing at least one color signal other than the certain color signal such that the composition ratios become identical with the calculated composition ratios.

摘要： There is provided a light shielding plate to shield light from a light source lamp, and this light shielding plate is rotated and driven by a light shielding plate drive circuit, and a charge stored in a CCD for a period of, for example, 20H at a start of an effective period J of a vertical scanning period, is discharged and this is set as a non-operating period and a drive control over the light shielding plate for a period of 40.5H which is a sum of this non-operating period and a blanking period B (20.5H) is performed.

摘要： An electronic endoscope system that provides, even when it uses a halogen lamp, an image having a brightness equal to that of an image obtained with a xenon lamp. The electronic endoscope system leads rays emitted from a halogen lamp to the tip of an electronic endoscope through a light guide, picks up an internal image of an object to be observed with a CCD through an objective optical system and reads out twice each of an odd field signal and an even field signal successively when a slow scan mode is selected. The odd or even field signal from each field is delayed by a delay memory in a luminance enhancement circuit, and the same field signals are added by an adder. The electronic endoscope system performs image processing of an addition signal thus obtained as a single odd or even field signal, thereby being capable of enhancing the luminance signal, for example, to a level twice as high.

摘要： A signal level correction circuit for a video signal includes a voltage control amplifier for amplifying a video signal received from a solid state image sensor with different gains for the respective chrominance signals, a first clamp circuit for setting a black level in the video signal received from the amplifier, a comparator for outputting a voltage proportional to the difference between a peak holding voltage of a capacitor in the horizontal blanking period of the video signal clamped by the first clamp circuit, and a reference voltage. An adder adds the output voltage from the comparator and the video signal from the first clamp circuit. A second clamp circuit resets the black level of the amplified video signal. A .gamma. correction circuit adjusts the .gamma. value of the video signal from the second clamp circuit. A clipping circuit clips the dynamic ranges between the white and black level of the .gamma. value corrected video signal. A third clamp circuit resets the black level of the video signal from the clipping circuit. An A/D converter converts the analog video signal into a digital signal.

摘要： A rotary shutter adapted to be used in an electronic still camera comprises a rotatable shutter having shutter openings which are variable in size. The shutter is rotated by an electric motor in order to open and close intermittently an exposure aperture of the camera. A phase detector for detecting the phase of rotation of the shutter member provides a series of phase signal, and cooperates with a signal generator for generating stop signals in synchronism with the phase signals when a particular shutter speed is selected and a circuit for braking the motor to stop the shutter member. Responsive to the particular shutter speed selecting operation, the shutter opening is opened to its maximum size and the rotary shutter is simultaneously stopped quickly in position so as to open fully the exposure aperture of the camera.
