摘要： An endoscope image signal photoelectrically converted by an image sensing device in an endoscope is compressed by an image compressing apparatus and then recorded in a recording apparatus, whereby the number of image frames recordable in the recording apparatus can be increased. Also, the image compression is effectively performed, for example, by changing a compression ratio dependent on a quantity of respective image information contained in plural components of the endoscope image signal, whereby a quantity of information actually recorded can be reduced.

摘要： An endoscopic photographing apparatus has a TV camera with a CCD image sensor which is mounted on an eyepiece section of an endoscope, a light flash source for supplying a light flash as photographing light to the endoscope, and an observation light source for supplying observation light. The light flash source is turned on in synchronism with a release signal and a transfer gate pulse for the video signal, at the time of still image photographing. The photographic field of view of the TV camera is darkened for at least one-field scanning period, before the light flash source is turned on.

摘要： In a camera attached to the eyepiece section of an endoscope is arranged a photoelectric element for generating photoelectric signal corresponding to the brightness of light reflected from an object and transmitted through an image guide in the endoscope. The photoelectric signal of the photoelectric element is converted by a current-voltage converter/integrator circuit to an observation light control signal at the time of observation while to photographing light control signal at the time of photographing. The current-voltage converter/integrator circuit also generates sync signal in response to the release action. Each of the observation light control signal, sync signal and photographing light control signal is transmitted to a light supply unit through a signal transmission line. The signal transmitted is judged through the light supply unit to be observation light control signal, sync signal or photographing light control signal according to its polarity and level. The light control of an observation light source or photographing light source is achieved according to signal judged.

摘要： A light source unit for an endoscope is provided with a light-emitting element and a light receiving element which are provided in an eyepiece section of an endoscope. The light-emitting element is supplied with current modified by a specific frequency from an oscillating circuit and produces a light-intensity modulated light. An output signal from the light receiving element is supplied to a filter circuit and a signal of the specific frequency component is taken out from the filter circuit to be compared with a reference voltage in a Schmidt circuit. When an operator approaches to the light receiving element and enters a range within a predetermined distance from the light receiving element, a light intensity of the light which is emitted from the light emitting element toward the operator, reflected from the operator, and is incident on the light receiving element, becomes large. As a result, a signal level supplied to the Schmidt circuit exceeds a predetermined value. At this time, a signal for turning on a light source is produced from the Schmidt circuit to energize a relay and to close a contact of the relay. Then, electric power is supplied from a power source to the light source to turn on the light source. As a result, an illuminating light is supplied from the light source to a light guide of the endoscope, whereby an area of an objective portion can be observed through an image guide of the endoscope.

摘要： A light flash control apparatus is used for an endoscope in which a solid-state image sensor is employed. A image signal derived from the solid-state image sensor during the illumination by a halogen lamp is also utilized as a photo-metric signal. An adequate quantity of flashlight for the image sensor is calculated in advance based upon the photo-metric signal. The calculated exposure time i.e., the desirable quantity of flashlight is stored in an integration circuit. After the given exposure time passes since the flash tube is ignited, it is forcibly turned-off by a turn-off thyristor.
