Abstract: An image processing device includes an image processing unit, an over-driving unit, and an up-sampler. The image processing unit receives a full-resolution 3D input image and outputs a half-resolution 3D image to a memory. The over-driving unit is coupled to the image processing unit and the memory for over-driving a current half-resolution 3D image outputted from the image processing unit according to a previous half-resolution 3D image stored in the memory. The up-sampler is selectively coupled to the over-driving unit for up-sampling an over-driven half-resolution 3D image outputted from the over-driving unit to output a full-resolution 3D output image.

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 image processing method is for subsampling a plurality of pixels of a frame. Related information about how subsample is applied to the pixels is generated. The pixels are subsampled so that respective numbers of bits of luminance components of the pixels are higher that respective numbers of bits of chroma components.
