Abstract
PURPOSE: To view a varying image in a bright state by reproducing plural pieces of video information which are multiply recorded intermittently in units of horizontal scanning lines, fields, or frames and outputting one piece of video information.
CONSTITUTION: Pieces A and B of video information are multiply recorded on a video tape intermittently and alternately at 1H intervals. When a photosensor 14 catches a specific target, a video switch 33 is switched to the lower side in a figure with a control signal at the timing of the reproduction of a horizontal scanning line of the video information A or to the upper side at the timing of the reproduction of a horizontal scanning line of the video information B. Consequently, when video information A1 is outputted, the same video information A1 is outputted continuously corresponding to a next horizontal scanning line. Further, when the photosensor 14 does not catch the specific target, the video switch 33 is switched reversely. Consequently, the image which varies corresponding to the output of the photosensor 14 is obtained.
