    • In order to obtain a quality image without deterioration owing to radiation noise in inspection using the optical video camera in high radiation environment, an inspection apparatus is formed of an image pick-up unit, an image obtaining unit which fetches a video image that contains a signal (noise) that is substantially independent of each frame obtained by the image pick-up unit, a local alignment unit which locally aligns frames with different time phases for forming the image fetched by the image obtaining unit, a frame synthesizing unit which synthesizes the plurality of frames aligned by the local alignment unit for generating a synthesis frame with an SN ratio higher than the SN ratio of the frame before frame synthesis, and an image output unit for displaying or recording the image formed of the synthesis frame generated by the frame synthesizing unit.
    • 为了在高辐射环境下使用光学摄像机的检查中的辐射噪声获得质量图像而不劣化,检查装置由图像拾取单元,图像获取单元,其获取包含 信号(噪声),其基本上独立于由图像拾取单元获得的每个帧;局部对准单元,其对具有不同时间相位的帧进行局部对准,以形成由图像获取单元获取的图像;帧合成单元, 由本地对准单元对准的多个帧,用于产生SN比高于帧合成之前的帧的SN比的合成帧;以及图像输出单元,用于显示或记录由帧生成的合成帧形成的图像 合成单位。
