Abstract

본 발명은 각각의 화소가입사광량에 대수함수적으로 신호전하를 발생하는 그러한 화소를 매트랙형태로 배치하고, 상기 신호전하를 전송하는 장치들로 구성된 고체촬상소자를 만들어 아주 맑은 부분과 어두운 부분이 혼재하는 피사체를 촬상할 경우 밝은 부분에 비해 상대적으로 어두운 부분의 화직이 염화되는 것을 방지하기 위한 것으로 광전소자의 광을 입사하는 부분에 포토크로믹 소재를 형성하여 높은 조도의 광을 차단하고 낮은 조도의 광은 그대로 촬상되도록 한 것이다.

Claims (3)

  1. 광전 변환 소자를 메트릭스 형태로 배치하여 각 화소가 입사광량에 비례하는 전하를 발생하므로 피사체를 촬상하도록 하는 소자에 있어서, 찰상소자의 각 화소를 광전축적 제어장치(11)와 광전소자(10)로 구성하여 포토다이오드(1)에 축적되는 전하량을 광량 대수함수적으로 비례하도록 조절함을 특징으로 하는 고체 촬상 소자.
  2. 제1항에 있어서, 광전소자(10)에서 광이 입사되는 부분인 칼라 필터부(5) 사이사이에 포토크로믹(9)을 형성하여 이루어짐을 특징으로 하는 고체 촬상 소자.
  3. 제1항 또는 제2항에 있어서, 광전소자(10)에서 광이 입사되는 칼라 필터부(5) 상방에 보호막(8)을 매개하여 포토 크로믹(9) 층을 형성하여 이루어짐을 특징으로 하는 고체 촬상소자.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
