Abstract

영상신호 발생장치와 일체화된 구조를 갖는 투사장치가 개시된다.Disclosed is a projection apparatus having a structure integrated with an image signal generator.

광신호가 입사되거나 투사되는 렌즈; 입사되는 광신호에 근거하는 화상신호를 발생하는 영상신호 발생부; 화상신호에 근거하는 광신호를 발생하는 디스플레이부; 렌즈를 통한 입사광이 화상정보 발생부로 입사되는 제1의 상태와 디스플레이부에서 발생된 투사광이 렌즈를 통하여 투사되는 제2의 상태를 갖는 제1광경로 변경장치를 포함함을 특징으로 한다.A lens on which an optical signal is incident or projected; A video signal generator for generating an image signal based on the incident optical signal; A display unit generating an optical signal based on the image signal; And a first light path changing device having a first state in which incident light through the lens is incident to the image information generating unit and a second state in which projection light generated by the display unit is projected through the lens.

본 발명의 투사장치는 카메라의 렌즈를 입사 혹은 투사시 공통으로 사용토록 하여 저가격으로 영상신호 발생장치와 투시장치를 일체형으로 구성할 수 있게하는 효과를 갖는다.The projection apparatus of the present invention has an effect that the lens of the camera can be used in common when the camera is incident or projected, so that the image signal generator and the projection value can be integrated at low cost.
