Title
(KO) 롤링 이미지 캡처 시스템에서의 주변 보정
Abstract
(KO)
롤링 이미지 캡처 시스템에서 획득되는 이미지의 주변광에 관한 보정에 관한 실시예들이 개시되어 있다. 일 실시예는 스크린, 롤링 이미지 캡처 시스템, 국소 광원, 및 제어기를 포함하는 디바이스를 제공한다. 제어기는 제1 이미지 데이터 프레임 및 제2 이미지 데이터 프레임을 획득하는 동안 국소 광원을 동작시켜서 제1 프레임을 위한 합산 지속시간 t + t이 픽셀 필드마다 제2 프레임을 위한 합산 지속시간 t + t이 상이하도록 주변광의 지속시간 및 국소+주변광의 지속시간 동안 각 이미지 센서 픽셀 필드를 집적하도록 구성된다. 제어기는 주변광 값을 판단하여 주변광 값에 기초하여 하나 이상의 픽셀들을 조정하도록 더 구성된다. local + ambient ambient local + ambient ambient
