Abstract: An image processing method for adjusting the luminance and contrast of an input image comprises the following steps. First, local spatial luminance statistics is performed on the first pixels of the input image to generate a luminance image including a plurality of second pixels. Then, from a preset mapping curve group comprising a plurality of smooth mapping curves, a corresponding smooth mapping curve is selected for each of the second pixels according to an adjusting function. Next, the pixel values of the second pixels are adjusted according to the corresponding smooth mapping curves to generate an adjusted image.

Abstract: 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 R2 number of luminance differences. Each of the R2 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.

Abstract: An image processing method for processing an interleaved image is disclosed. A reference window and direction windows matched to the reference window are set with respect to known pixel rows in the interleaved image. First parameters along candidate directions of the reference window is calculated, wherein the first parameters denote pixel differences between the reference window and the direction windows. A respective first direction, among direction groups of the candidate directions and corresponding to a minimum of the first parameters, is found. First and/or second portion direction of first and second portions of the interleaved image are found among the first directions. The first and the second portions of the interleaved image are identified according to the first parameters. A center pixel of the reference window is obtained by interpolation according to the first and the second portion directions.
