Summary:An assessment device according to an embodiment of the present disclosure communicates with an image sensor. A method of operating an assessment device includes the steps of: receiving raw image data obtained by capturing a test chart by an image sensor; generating conversion image data based on the color domain conversion of the raw image data; generating estimation image data by estimating a non-distortion image based on the conversion image data; and assessing the color distortion of the image sensor based on the estimation image data and the conversion image data. 본 개시의 일 실시 예에 따른 평가 장치는 이미지 센서와 통신한다. 평가 장치의 동작하는 방법은, 이미지 센서에 의해 테스트 차트를 캡처함으로써 획득된 원시 이미지 데이터를 수신하는 단계, 원시 이미지 데이터의 색상 도메인 변환에 기초하여 변환 이미지 데이터를 생성하는 단계, 변환 이미지 데이터에 기초하여 비-왜곡 이미지를 추정함으로써 추정 이미지 데이터를 생성하는 단계, 및 추정 이미지 데이터 및 변환 이미지 데이터에 기초하여, 이미지 센서의 색상 왜곡을 평가하는 단계를 포함한다.
