Abstract:
Raster lines are obscured in a photograph of an image displayed on a video monitor. A photographic film is used as an integrating mechanism. The TV raster is vertically displaced during the camera shutter open time a total deflection of one horizontal line, thus blending the information between horizontal lines. Vertical raster deflection is accomplished by adding a series of delays to the normal vertical sync and then generating a processed composite sync to drive the external sync input to the monitor. The shutter is open for several video frames, each frame being deflected vertically by an integer amount greater than the previous frame until the total raster deflection equals one horizontal line.
