Structure of image projection, video projection method, and a video projection window

The present invention provides the background without reducing the projected image seen through the window image visibility and capable of high visibility video projection projected image window. The present invention is solved by providing the following image projecting structure of the above problems: transmittance of visible light of at least 5% to 90%, in front of haze in 4 40 or less, the rear haze in the image projection structure 0 60 or less, so that when the light with an angle of 45 ° to the incident surface of the projection image of the structure, the intensity of backscattered light intensity is lower than the forward scattered light.
