    Abstract: Provided are a method and apparatus for compensating for a crosstalk between views in a three-dimensional (3D) display apparatus. The method and the apparatus may pre-set a crosstalk weight matrix through an actual measurement by considering a characteristic of a display. The crosstalk weight matrix may offset an effect that each of multiple views affects other different views. Also, when multi-view input signals are received, the method may generate luminance-compensated multi-view input signals by multiplying the crosstalk weight matrix and a luminance matrix that includes a luminance of each of the multi-view input signals, and may output the luminance compensated multi-view input signals as input signals of the display.

  • Publication number: 20100091029
    Abstract: An image processing method for reducing a power consumption. The image processing method may reduce the power consumption by classifying an input content into a conversion target region and a preservation target region and by converting a luminance of pixels included in the conversion target region. Also, the image processing method may effectively perform a luminance conversion for pixels by separating the input content into the conversion target region and the preservation target region based on a luminance of the pixels of the input content. The image processing method may convert the luminance of the pixels of the conversion target region to maintain a contrast between text pixels and background pixels.
