ABSTRACT:
A video projection system using a light modulating display device having a row and column matrix of picture elements is improved by imparting an oscillatory motion to the display image in the plane of the image, to thereby reduce the visibility of the individual picture elements of the matrix. The resolution of the image can be increased by displaying different video information at different parts of the oscillatory cycle.
