The system is composed of a video camera, an A/D converter, a personal computer (PC) and a computer program. Analog video image of the solar array from the video camera is converted to digital one by the AD converter. The digital video image is recorded directly on a hard disk drive connected to the PC during an experiment without dropping any video frames. After the experiment, a picture image is extracted in memory bank from the stored video image by the computer program and is compared with a first frame of the video image. The position of arcs is identified by means of repeating this comparison over all frames. The system is built at a low cost with commercial hardware and reduces the time required for analysis remarkably.}, pages = {82--84}, title = {動画処理による真空環境下での太陽電池アレイ放電発生位置特定システムの開発}, volume = {51}, year = {2003}, yomi = {トヨダ, カズヒロ and チヨウ, メンウ and ヒキタ, マサユキ} }
