Abstract:
1. A data modulation method comprising: comparing a first left eye image data of a (4N+1)-th (where N is a positive integer) frame period with previous frame data of a 4N-th frame period, selecting a preliminary modulation value for a left eye image based on a result of the comparison, and preliminarily modulating the first left eye image data to reach a target brightness of the first left eye image data using the preliminary modulation value for the left eye image; secondarily modulating a second left eye image data of a (4N+2)-th frame period to reach a target brightness of the second left eye image data using a secondary modulation value for the left eye image, the secondary modulation value for the left eye image being equal to or smaller than the preliminary modulation value for the left eye image; comparing a first right eye image data of a (4N+3)-th frame period with previous frame data of the (4N+2)-th frame period, selecting a preliminary modulation value for a right eye image based on a result of the comparison, and preliminarily modulating the first right eye image data to reach a target brightness of the first right eye image data using the preliminary modulation value for the right eye image; and secondarily modulating a second right eye image data of a (4N+4)-th frame period to reach a target brightness of the second right eye image data using a secondary modulation value for the right eye image, the secondary modulation value for the right eye image being equal to or smaller than the preliminary modulation value for the right eye image.
