  • Publication number: 20120170841
    Abstract: A view transformer of an image processing apparatus may generate a first view transformation image by transforming a first view color image with a first resolution to a third view, and may generate a second view transformation image by transforming, to the third view, a second view color image with a second resolution higher than the first resolution. A parameter calculator of the image processing apparatus may calculate a per-pixel weight parameter that is applied to each of the first view transformation image and the second view transformation image. An image generator of the image processing apparatus may generate a third view color image corresponding to the third view by applying the calculated per-pixel weight parameter to the first view transformation image and the second view transformation image.

  • Patent number: 8194092
    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.

  • Patent number: 7649652
    Abstract: A method and apparatus for expanding bit resolution using local information of an image receives an input image. First, second and third threshold value used to enhance bit resolution, to detect a texture and to detect a pattern, respectively, are determined considering global information of the input image. A texture existing in a mask region composed of surrounding pixels within a predetermined range around a current pixel is determined using the second threshold value. A regularly repeated pattern existing in the mask region is determined using the third threshold value if no texture exists in the mask region. The first threshold value is decreased if a texture or pattern exists in the mask region. Values of mask region pixels are adjusted depending on the first threshold value, and bit resolution of the current pixel value is enhanced using a resultant value obtained by filtering the adjusted pixel values.
