Zusammenfassung: | A film inspection device comprises a transfer roller, an inspection vision unit, and an error determination unit. The transfer roller transfers a film in which a pattern is formed by irradiation of a laser beam in a first direction. The inspection vision unit has a plurality of capturing pixels arranged in the first direction, and generates a capturing image by capturing the film while moving in a second direction crossing the first direction at right angles. The error determination unit determines an error of the pattern that the film has based on the capturing image.
필름 검사 장치는 이송 롤러, 검사 비전부 및 오차 판단부를 포함한다. 이송 롤러는 레이저빔의 조사에 의해 패턴이 형성된 필름을 제1 방향으로 이송시킨다. 검사 비전부는 제1 방향을 따라 배열된 복수의 촬영 픽셀들을 갖고, 제1 방향에 직교하는 제2 방향으로 이동하면서 필름을 촬영함으로써 촬영 영상을 생성한다. 오차 판단부는 촬영 영상에 기초하여 필름이 갖는 패턴의 오차를 판단한다. |
