Based on integral photography and computer graphics,a new method for recording color holograms of virtual 3D objects using single wavelength laser is proposed. Three horizontal parallax only integral photography (IP) images whose colors correspond to tricolor are calculated by simulating integral photography. IP images are illuminated with the coherent beam from the opposite side. Three images of the virtual 3D object are reconstructed and overlapped on a particular image plane by three liner micro-lens arrays. With interfering the reconstructed 3D images and the reference beam after a single exposure,a color hologram is created. Experimental implementation of the new method for a simple case is presented.
