PROBLEM TO BE SOLVED: To provide a video projecting system for projecting plural pictures respectively having the same properties in terms of luminance, contrast, and color reproduction. SOLUTION: The respective video projecting systems have spatial optical flux modulating means 35, 36 and 37, and the specified number of projectors 115, 116 and 117 corresponding to the number of individual pictures 55, 56 and 57, and the respective means are optically connected to a light source 100. A means 111 for dividing a luminous flux 1 into the specified number of partial luminous fluxes 2, 3 and 4 corresponding to the number of projectors is arranged behind the light source 100 on an optical path. Intensity modulating means 25, 26 and 27 are arranged on the partial optical paths 15, 16 and 17 of the respective partial luminous fluxes, and the intensity modulating means and the spatial luminous flux modulating means are arranged on one of the partial optical paths and also controlled by the signals A, B and C of video sources 105, 106 and 107.
