摘要： Arranged within a measuring-light generating unit of an endoscope apparatus for three dimensional measurement, according to the invention, are measuring means, a lamp for outgoing a normal illuminating light, and a laser for outgoing a measuring light. Connected to the measuring means is a signal line which is connected to a CCD. Further, an illuminating light outgone from the lamp is condensed by a condenser lens, and is incident upon an incident end surface of a light guide. Furthermore, the measuring light outgone from the laser is condensed by the condensing lens, and is incident upon the incident end surface of the image guide. Moreover, the incident end of the image guide is connected to scanning means formed by a piezo-electric element, a speaker (voice coil) or the like through a connecting element. The scanning means is operated whereby the incident end of the image guide is reciprocally moved in a direction perpendicular to an optical axis of the measuring light. The measuring light is a light having extension or spreading. However, a flux of light of the measuring light is extremely thin, and a spot light having minimum resolution that is a single glass fiber forming the image guide is projected onto the subject.

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.

摘要： An electronic flash apparatus comprises a flash lamp and a semiconductor switching element which are connected in series across a main capacitor, and a flash control circuit which measures light reflected from an object to be photographed illuminated by flash light produced by the flash lamp, and produces a control signal to render the semiconductor switching element nonconductive. The flash control circuit includes a photoelectric converting circuit for converting the reflected light into a voltage signal, an integrator for integrating the voltage signal, and a comparator for comparing the output voltage from the integrator with a reference voltage. To obtain a proper flash exposure a compensation signal generating circuit is provided which is responsive to the initiation of flashing of the flash lamp to produce a compensation signal having a desired waveshape. The compensation signal acts on the flash control circuit to control the generation timing of the control signal. The flash light produced by the flash lamp after the switching element has been rendered nonconductive is positively used for a proper exposure.
