Abstract (in Japanese) (See Japanese page) 
(in English) An approximation of the cosine function is one of the solution for reducing the computational load in holographic calculation. Our previous work, which approximates the cosine function by a combination of addition, modulo and absolute operation, is proved to be effective for accelerating holographic calculation; however, its approximation error also degrades a performance of a hologram. In this study, we propose an error compensation method which is based on our previous work, and succeeded in reducing the mean absolute error by about 85% compared to our previous work. Moreover, our work also succeeded in improving an image quality of reconstruction image of computer-generated hologram.
