PROBLEM TO BE SOLVED: To provide a convolution integration arithmetic unit which can prepare a computer hologram capable of reproducing reproduction images for which reproduction points are present in the various kinds of distances at a high speed. SOLUTION: For this convolution integration arithmetic unit, plural element processors PEs are practically cascade-connected. The respective element processors PEs are provided with a memory 91 for outputting a propagation function generated based on a coordinate value Z, a multiplier 92 for multiplying the propagation function outputted from the memory 91 and a luminance value I and outputting a multiplied value, an adder-subtractor 93 for adding and subtracting the multiplied value outputted from the multiplier 92 and hologram time sequential signals PDin and outputting an added-subtracted value and a register 94 for inputting and holding the added-subtracted value outputted from the adder-subtractor 93 and outputting it as the hologram time sequential signal PDout. The hologram time sequential signal PDout outputted from the register 94 of the element processor of a cascade connected preceding stage is inputted to the adder-subtractor 93 of the element processor of a poststage as the hologram time sequential signal PDin. |
