iPhone iOS4 로우 레벨 카메라 컨트롤?

Question

iPhone 4의 iOS4에서 셔터 속도, 조리개 또는 ISO와 같은 저수준 스틸 카메라 설정을 수동으로 설정하는 방법이 있습니까? 나는 그것이 공식 SDK에 존재한다고 생각하지는 않지만 누군가가 이것을 허용하는 일부 비공개 API를 발견했을 것입니다.

꽤 괜찮은 조명이라 할지라도 피사체가 전혀 움직이지 않으면 모션 블러를 일으키는 가장 느린 1/15 초 셔터 속도로 촬영해야하기 때문에 iPhone 4 카메라를 사용할 수 없게됩니다.

감사합니다.

Answer 1

직접적으로. 버그 보고서를 제출하십시오.

예, 사용 가능한 비공개 API가있을 수 있지만 이는 제한적으로 사용됩니다.

Answer 2

이보십시오, 나는 당신을 위해 유용 할 수있다 : 당신은 적어도 아이폰 OS 6에서 개인 API를 사용하여이 작업을 수행 할 수
