Abstract

When image sensor and lens are fixed on the module, mechanical errors often induce tilt, rotation, or narrow field-of-view of the acquired image. Therefore, the optical characteristics of image sensor modules should be tested by test equipments. This paper explains how to test the optical characteristics of images sensors. It also proposes the standardized description methods of optical characteristics tests which are similar with those of image acquisition characteristics tests. The proposed method helps the test equipments to perform image acquisition characteristics tests and optical characteristics tests together.

이미지 센서와 렌즈를 모듈 상에 고정할 때, 기계적인 오차로 인해 취득된 영상의 기울임 또는 회전이 발생하기도 하고 화각이 좁아지기도 한다. 따라서 테스트 장비에서 이미지 센서 모듈의 광학적 특성을 테스트하여야 한다. 본 논문에서는 이미지 센서 모듈의 광학적 특성을 테스트하는 방법을 설명하고, 이를 영상 취득 특성과 유사한 방식으로 표준화한 기술 방법을 제안한다. 제안된 방법은 테스트 장비가 영상 취득 특성과 광학적 특성을 함께 테스트하는데 도움이 된다.
