Abstract

Abstract An image picking-up and processing apparatus particularly suitable for use in dental treatment comprises a transmission and conversion section including an image sensor for detecting input light from an object, an objective lens, and a light guide for transmitting illumination light; a control section including a control unit for producing an image signal on the basis of an output signal from the image sensor, and a light source for emitting the illumination light; and an interchangeable image processing section detachably connected to the transmission and conversion section for processing the image signal to reproduce image information in a desired form. An interchangeable image picking-up section, for example, an endoscope including an objective lens, an image fiber for transmitting the input light, and a light guide for transmitting the illumination light is detachably connected to the transmission and conversion section.

Claim 1
Independent Claim 162 words
An image picking-up and processing apparatus, comprising: a transmission and conversion section comprising an image sensor for detecting input light which carries first image information of an object, a first objective lens for focusing said input light on said image sensor, and a first light guide for transmitting illumination light to illuminate said object, a front end portion of said transmission and conversion section having a structure enabling detachable connection to an interchangeable image picking-up section; a control section comprising a control unit for controlling said image sensor, and producing an image signal on the basis of an output signal from said image sensor, a light source for emitting said illumination light, and a second light guide for transmitting said illumination light from said light source to said first light guide; and an interchangeable image processing section for processing said image signal to reproduce second image information in a desired form, said image processing section being detachably connected to said control section.
Claim 2
Dependent Claim 162 words
An image picking-up and processing apparatus, comprising: a transmission and conversion section comprising an image sensor for detecting input light which carries first image information of an object, a first objective lens for focusing said input light on said image sensor, and a first light guide for transmitting illumination light to illuminate said object, a front end portion of said transmission and conversion section having a structure enabling detachable connection to an interchangeable image picking-up section; a control section comprising a control unit for controlling said image sensor, and producing an image signal on the basis of an output signal from said image sensor, a light source for emitting said illumination light, and a second light guide for transmitting said illumination light from said light source to said first light guide; and an interchangeable image processing section for processing said image signal to reproduce second image information in a desired form, said image processing section being detachably connected to said control section.
Claim 3
Dependent Claim 37 words
An image picking-up and processing apparatus as claimed in claim 1, wherein said apparatus can detect said input light and reproduce said second image information without connecting said image picking-up section to said transmission and conversion section.
Claim 4
Dependent Claim 44 words
An image picking-up and processing apparatus as claimed in claim 1, further comprising as said image picking-up section a protection adaptor for protecting a mechanism inside said transmission and conversion section at least from water and tooth shavings which occur in a dental treatment.
Claim 5
Dependent Claim 48 words
An image picking-up and processing apparatus as claimed in claim 1, further comprising as said image picking-up section a film adaptor for holding a film such that an image of said film is focused on said image sensor when said film is illuminated by an external light source.
Claim 6
Dependent Claim 36 words
An image picking-up and processing apparatus as claimed in claim 1, further comprising as said image picking-up section a zooming mechanism adaptor including a lens system capable of performing zooming operation with respect to said object.
Claim 7
