PURPOSE:To obviate roughness and flickering of a raster and to improve the picture quality of a composite image by converting a video signal from a video camera and a living body signal from a living body signal detecting part into video signals of non-interlace, respectively, synthesizing these video signals and executing the monitoring. CONSTITUTION:The recorder is constituted of a living body signal detecting part (an electroencephalograph and an electrocardiograph, etc.) 2 for amplifying a living body signal (a brain wave and an electrocardiogram, etc.) s1 from an electrode installed in a person 1 to be examined, a video camera 3 for monitoring the person 1 to be examined, a scan converter 7 for converting a video signal v1 from the video camera 3 into a video signal vn1 of non- interlace, a waveform memory 8 for converting living signals s2, s4 from the living body signal detecting part 2 into a video signal (a living body waveform) vn2 of non-interlace, a video signal synthesizing circuit 9 for synthesizing the video signal vn1 from the scan converter 7 and the video signal vn2 from the waveform memory 8, and a high scan monitor 10 corresponding to non-interlace for displaying a composite video signal V from the video signal synthesizing circuit 9 as a composite image on the same screen. |
