Claim:
1. A method of generating a hologram, the method comprising: dividing 3D image data into data groups which are independent from one another, by a first processor; calculating, from at least one of the data groups, hologram values to be displayed at respective positions on a hologram plane, by the first processor, the hologram values indicating values regarding an interference pattern by interference between an object wave and a reference wave, at the respective positions on the hologram plane, by object points in the at least one of the data groups; calculating, from at least another one of the data groups, hologram values to be displayed at the respective positions on the hologram plane by a second processor in parallel with the first processor, the hologram values indicating values regarding an interference pattern by interference between an object wave and a reference wave, at the respective positions on the hologram plane, by object points in at least another one of the data groups, and summing the calculated hologram values for each of the respective positions on the hologram plane, by the first processor or the second processor, or by the first processor and the second processor in parallel, wherein the dividing comprises dividing the 3D image data into the data groups based on primary color components of a color model set for the first processor, in the dividing of the 3D image data, image data of each of the data groups is divided into a plurality of depth images based on depth information from the hologram plane, and the method further comprises, with respect to each of plane images of the 3D image data defined by the primary color components and the depth information:
