Modified conventional method for capturing light field using mirror ball is proposed to extend the capturing light field. Two types of mirror sphere array pattern is introduced to capture the rays from various directions and positions passed the light fields and inter-reflected rays by neighbored sphere are also considered to capture the light field. Amount and direction of those captured rays are evaluated by the ratio of the acquired light fields and it is shown that the rays can be captured precisely and effectively compared with conventional method. It is also shown that the method is significant for the appearance of computer generated synthetic object.
