Abstract:
(EN) The present invention relates to a test automation system for judging image distortion in a digital image device. In order to judge whether or not an image is distorted, the invention: generates a watermark by generating a TDFD (Temporal Drop-Frame Detection) signal for judging a frame drop occurring in a time axis of a video and an SDBD (Spatial Distort-Block Detection) signal for judging the image distortion in an image frame; inserts the generated watermark into a reference image; and extracts an image distortion judgment signal from the reference image when the reference signal into which the watermark is inserted is outputted through an image output device. For the purpose of judging whether or not an auto-focus and exposure functions are normally operated in an image acquisition device, the invention also: generates the watermark by generating not only an AFED (Auto Focus Exposure Detection) signal for judging whether or not the auto-focus and exposure function is normally operated in the image acquisition device but also a pilot signal for responding to the 2D movement of the reference image; inserts the generated watermark into the reference image; obtains the reference image including the inserted watermark through the image acquisition device; and then extracts the image distortion judgment signal from the obtained reference image.
(FR) L'invention concerne un système de test automatique pour évaluer une déformation d'image dans un dispositif d'image numérique. Afin d'évaluer si une image est déformée ou non, l'invention consiste à : générer un filigrane par génération d'un signal de détection temporelle d'abandon de trame (TDFD) permettant d'évaluer un abandon de trame qui se produit sur un axe temporel de vidéo et d'un signal de détection spatiale de bloc de déformation (SDB) permettant d'évaluer une déformation d'image dans une trame d'image ; introduire le filigrane généré dans une image de référence ; et extraire un signal d'évaluation de déformation d'image à partir de l'image de référence lorsque le signal de référence dans lequel le filigrane a été introduit est émis via un dispositif de sortie d'image. Afin d'évaluer si des fonctions de mise au point automatique et d'exposition fonctionnent normalement ou non dans un dispositif d'acquisition d'image, l'invention consiste également à : générer le filigrane par génération non seulement d'un signal de détection d'exposition et de mise au point automatique (AFED) permettant d'évaluer si des fonctions de mise au point automatique et d'exposition fonctionnent normalement ou non dans un dispositif d'acquisition d'image, mais également d'un signal pilote pour répondre au mouvement 2D de l'image de référence ; introduire le filigrane généré dans l'image de référence ; introduire le filigrane généré dans l'image de référence ; obtenir l'image de référence comprenant le filigrane introduit via le dispositif d'acquisition d'image ; et extraire le signal d'évaluation de déformation d'image à partir de l'image de référence.
(KO) 본 발명은 디지털 영상 장치의 영상 왜곡 판단 테스트 자동화 시스템에 관한 것으로서, 동영상의 시간 축에서 발생하는 프레임 드롭(Frame Drop)을 판단할 수 있는 TDFD(Temporal Drop-Frame Detection) 신호 및 영상 프레임 내의 영상 왜곡을 판단할 수 있는 SDBD(Spatial Distort-Block Detection) 신호를 발생하여 워터마크를 생성하고, 생성한 워터마크를 기준 영상에 삽입하며, 워터마크가 삽입된 기준 영상이 영상 출력 장치를 통해 출력될 때 기준 영상에서 영상 왜곡 판단 신호를 추출하여 영상 왜곡 여부를 판단한다. 또한, 본 발명은 영상 획득 장치의 자동 초점 및 노출 기능의 정상 동작 여부를 판단할 수 있는 AFED(Auto Focus Exposure Detection) 신호 및 상기 기준 영상의 2차원적 이동에 대응하기 위한 Pilot 신호를 발생하여 워터마크를 생성하고, 생성한 워터마크를 기준 영상에 삽입하며, 워터마크가 삽입된 기준 영상을 영상 획득 장치를 통해 획득한 후, 획득한 기준 영상에서 영상 왜곡 판단 신호를 추출하여 영상 획득 장치의 자동 초점 및 노출 기능의 정상 동작 여부를 판단한다.
