제 2도는 고체 촬상소자의 한예를 나타낸 개략 설명도.
제 3도는 (a) (b) (c)는 광펄스와 화상신호의 위상관계를 나타낸 도면.

Claims (8)

  1. 다수의 화소가 배열된 고체 촬상소자와, 피사체를 광펄스로 조사하는 장치와, 상기 고체 촬상소자로 부터의 연속된 피일드 화상 신호로부터 생성되는 1 프레임 화상을 기억하는 장치 프레임 화상을 움직이는 화상 또는 정지 화상으로서 표시되는 장치를 구비한 TV식 내시경 장치에 있어서, 전술한 광펄스의 조사를 둘 이상의 피일드 기간에 걸쳐진 최단기간 내에서 행하도록한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사방법.
  2. 제 1 항에 있어서, 고체 촬상 소자로부터의 연속된 피일드 화상신호의 제 1, 제 2 등 2개의 피일드 화상신호로부터 1 프레임 화상을 생성하는 경우에 광펄스의 조사는 제 1 피일드 기간의 종단부분 및 제 2 피일드 기간의 시단부분에서 행하도록 한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사방법.
  3. 제 1 항에 있어서, 고체 촬상소자로부터의 연속된 제1, 제2, 제3 세개의 피일드 화상신호로부터 칼라의 1 프레임 화상을 생성하는 경우에 광 펄스의 조사를 제 1 피일드 기간의 종단부분에 제 1의 색으로, 제 2피일드 기간의 위치의 시기에 제 2의 색으로, 제 3피일드 기간의 시단부분에 제 3의 색으로 행하도록 한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사방법.
  4. 제 1 항 또는 제 3 항에 있어서, 1회에 조사되는 광펄스를 재차 여러개의 광펄스로 한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사방법.
  5. 피사체에 조사되는 광펄스를 발생하는 광 펄스 발생장치와 피사체에 조사된 광펄스의 반사성분에 따라서 이 피사체의 피일드 화상신호를 출력하는 고체 촬상 소자를 구비하고, 이 고체 촬상 소자로부터 연속해서 출력되는 제1, 제 2의 피일드 화상 신호를 기본으로 전술한 피사체의 프레임 화상을 형성하는 내시경 장치에 있어서, 전술한 광펄스 발생 장치는 연속광을 발생하는 광원과 이 광원으로부터 발하여진 연속광으로부터 제 1의 피일드 기간의 종단부분 및 제 2의 피일드 기간의 시단 부분에서 전술한 피사체에 조사되는 광펄스를 생성하는 로우터리 셔터가 있는 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사장치.
  6. 제 5항에 있어서, 전술한 로우터리 셔터는 서로 인접되게 설치되며, 또한 전술한 광원으로부터의 연속광을 펄스 형상으로 통과시키는 제1, 제 2 노광 개구부를 설치해서 된 회전 차폐판이 있는 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사장치
  7. 제 6항에 있어서, 전술한 회전 차폐관은 회전 차폐관의 회전축과 전술한 연속 광축과의 축간 거리의 변경에 의해서 전술한 광펄스의 조사시간을 바꿀 수 있도록 형성한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사장치
  8. 제 6항에 있어서, 전술한 회전 차폐관은 제1, 제2 노광개구부를 제외한 영역에 광을 차폐하는 처리를 한 것을 특징으로 하는 TV식 내시경 장치의 광펄스 조사장치
