Abstract
Official abstract text for this publication.
An overdrive device includes a training unit, an analysis unit and a Contrast adjustment unit. The training unit establishes a luminance difference look-up table (LUT) having an R 2 number of luminance differences. Each of the R 2 number of luminance differences represents a luminance difference between a measured display luminance value and a target luminance value of a display device when each of first and second viewing angle images correspond to any value of a grayscale range R. With respect to first and second viewing angle input image data, for pixel data therein corresponding to a same pixel position, the analysis unit looks up the luminance difference LUT to obtain a looked-up luminance difference, and accordingly calculates a luminance difference index. The contrast adjustment unit partially adjusts the grayscale of the second viewing angle image according to the luminance value index to obtain headroom for an overdrive operation.
First claim
Opening claim text (preview).
What is claimed is: 1. An overdrive device, applied to an active shutter three-dimensional (3D) system, for respectively display a first viewing angle image and a second viewing angle image in first and second viewing angle display periods which are adjacent and sequentially triggered, the first and second viewing angle images having a grayscale range R, R being a natural number greater than 1, the overdrive device comprising: a training unit, for establishing a luminance differen…
