  • Patent number: 6753920
    Abstract: An electronic camera for producing a composite image having a wide dynamic range and a high quality by composing first and second image signals obtained by picking-up an object successively two times with first and second stroboscopic flash exposures having a predetermined exposure amount ratio, including a CCD image sensing element, a stroboscopic flash device, and a flash light control circuit for controlling an excited emission of said stroboscopic flash device. At an end of the first exposure, the excited light emission from the stroboscopic flash device is temporarily stopped, but an excited condition of the stroboscopic flash device is kept. During this very short light emission interruption period, electrostatic charges stored in a light receiving section of the CCD image sensing element during the first exposure are transferred into a vertical transfer section. After that, the excited flash light is emitted again to perform the second exposure without recharging a trigger capacitance.

  • Publication number: 20040116952
    Abstract: A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated using the secondary battery as a driving power source and used to perform surgery on a living tissue. Electromagnetic energy generated by an energy generation unit located outside the surgical instrument is received by a reception coil incorporated in the surgical instrument with the surgical instrument held in noncontact with the energy generation unit. The electromagnetic energy is then converted into charging power with which the secondary battery is recharged. Thus, the surgical instrument can be readily recharged while left clean.

An interference optical system can be realized inexpensively. In the optical imaging device, low coherent light passed through an optical coupler and another optical coupler, irradiated from an optical scanner probe, reflected from an observed point in a living tissue, returned to the optical coupler, propagated over a fourth SM optical fiber, and routed to another optical coupler shall be referred to as sample light. Light passed through an optical length variation optical system via the optical coupler and routed to the optical coupler shall be referred to as reference light. At this time, a difference between a delay time undergone by the sample light and a delay time undergone by the reference light is proportional to a difference between an optical length for the sample light and an optical length for the reference light.

  • Publication number: 20040109319
    Abstract: An illumination control system comprises a rotation detecting section, an abnormality determination section, and a filter removing section. The rotation detecting section detects the rotational driving of a filter which is located on a path of illumination light emitted from a light source, which irradiates color light rays having different wavelengths to an object, and which is driven by a rotational driver. The abnormality determination section determines whether status of filter rotation is normal or abnormal based on the detected rotation of the filter by the rotation detecting section. The filter removing section removes the filter from the path of the illumination light when the abnormality determination section determines that the status of filter rotation is abnormal.
