<P>PROBLEM TO BE SOLVED: To provide a clock calibration device and a clock calibration method for solving the problem that display quality of a three-dimensional image is adversely affected due to delay by shutter opening/closing and for improving possibility that a customer purchases 3D glasses. <P>SOLUTION: This invention discloses a clock calibration device (1). The clock calibration device (1)is applied to 3D glasses and includes; a reception unit (10) which receives a first timing signal (201) transmitted from an image facility (2); and a processing module (12) which synchronizes a second timing signal (111) of the 3D glasses with a period of the first timing signal (201), compares the period of the first timing signal (201) with the period of the second timing signal (111) to obtain an average deviation amount (301) after prescribed time elapses, and adjusts the period of the second timing signal (111) in response to the average deviation amount (301) so that it is synchronized with the period of the first timing signal (201). <P>COPYRIGHT: (C)2013,JPO&INPIT |
