1. Apparatus for making three dimensional images comprising: a. a left and a right color video camera each producing an output comprising 3 image planes each plane corresponding to red, green and blue color information respectively, b. means for providing green and blue image planes from one of the left or right color video camera and a red image plane from the other color video camera as an output signal, and c. means for monitoring the color value of each pixel of the output signal and, when the value lacks a first threshold amount of blue or green color or lacks a second threshold amount of red or green color, adding a quantity of blue and/or green color or a quantity of red and/or green color, respectively, to the pixel color value, whereby information from two color video cameras is combined into three dimensional color images which contain no pure blue or pure red pixels.
