Claims (2)

  1. 페이스 플레이트면에 바이어스 조명장치로 부터의 바이어스 광이 비추어지는 촬상관의 출력 신호에 정적음영 보정신호 및 블랙게이트 펄스를 각각 혼합하여 얻어진 혼합신호를 선처리 회로에 공급하는 촬상장치에 있어서 온도변화에 의한 촬상관 출력신호중의 바이어스광에 의한 신호전류 성분의 변화를 소지시키기 위하여 위 정적음영 보정신호의 위 블랙게이트 펄스의 다중기간 부근의 레벨을 이 온도변화에 따라 실직적으로 변화시켜 이 온도변화에 의한 위 바이어스 광의 광 강도변화에도 불구하고 위 혼합신호의 클램프 레벨과 혹 레벨을 각각 거의 일치시키도록 구성한 것을 특징으로 하는 촬상장치의 온도 보정방식.
