Abstract

In general, image acquisition characteristics tests of image sensors and modules vary widely according to the characteristics of image sensors and modules under test, the application purpose of target devices where image sensors and modules are mounted, and the functions of test equipments. However, some de facto standard tests are frequently used in industry fields. They differ only in several parameters e.g. thresholds for fault detection, and they can be applied to most image sensors and modules. In this paper, 11 typical tests are explained in detail, and they are described in a simple and clear form under single framework, which significantly reduces errors and saves efforts.

일반적으로 이미지 센서 및 모듈의 영상 취득 특성 테스트는 테스트할 이미지 센서 및 모듈의 특성, 해당 센서 및 모듈이 장착될 기기의 사용 목적, 테스트 장비의 기능 등에 따라 세부적인 내용은 많이 다르지만, 산업체에서 자주 사용되어 사실상 표준으로 굳어진 몇몇 테스트는 불량을 판별하기 위한 기준치 등 몇몇 파라미터만 다르게 하여 대부분의 이미지 센서 및 모듈에 적용된다. 본 논문에서는 이들 중에서 대표적인 11개 테스트를 자세히 설명하고, 이를 단일 프레임워크 내에서 간단하고 명확한 형태로 표기하여 테스트 프로그램을 작성할 때의 오류와 노력을 크게 줄이도록 한다.
