摘要:
An apparatus, method and medium outputting a wide gamut space image in which one or more parameters that are needed to convert an existing color space into a wide gamut space are experimentally determined and then are applied to an image. The apparatus includes a feature extraction module to extract one or more feature differences between a standard gamut and a wide gamut of an image, a color range setting module to set a hue range according to the extracted feature differences and one or more experimentally determined parameters, and a conversion module to convert the image according to the extracted feature differences, the experimentally determined parameters, and the hue range.

Provided is an image-resolution-improvement apparatus and method which can increase the resolution of an input image at a high magnification to thereby obtain a high-quality final image. The apparatus includes a textured-region-detection unit to detect a texture region in an input image; and a final-image-generation unit to synthesize a first intermediate image and a second intermediate image, which are obtained by applying different interpolation techniques to the texture region and a non-texture region excluding the texture region and generating a final image.

Provided is a method and apparatus to perform gamut mapping between heterogeneous devices, more particularly, a method and apparatus to map a color of a device to an identical or visually and sensually preferable color of another device having a different color gamut. The method includes adjusting lightness of a color of a source device by scaling to match a lightness range of the source device with a lightness range of a destination device; modifying the adjusted lightness of the color of the source device by adjusting a color gamut of the source device to a color gamut of the destination device; and to map the modified color of the source device to a color in the color gamut of the destination device.

A system, medium, and method calibrating gray data. The system calibrating gray data includes a transformation unit to transform red, green, and blue (RGB) data of a source device into transformed color data of a different color space using a color appearance model, and a calibration unit to map a chroma value of gray data, corresponding to the transformed color data, in the different color space to a predetermined value to generate calibrated color space data.

Provided is a technology which can prevent deterioration of image quality when enhancing resolution of a predetermined key frame in a video sequence. Specifically, an apparatus to enhance resolution of a video frame is provided. The apparatus includes a frame extraction unit which extracts a key frame and one or more neighboring frames of the key frame from a video sequence; an upsampling unit which upsamples the key frame and the neighboring frames; a motion-vector search unit which calculates a motion vector of the upsampled key frame using the upsampled neighboring frames as reference frames; and a key-frame estimation unit which enhances quality of the upsampled key frame using temporal information obtained from the motion vector and spatial information in the key frame.

A method for tone calibration and an apparatus using the same are provided. The method for tone calibration includes outputting a reference patch of a predetermined color and a plurality of sample patches having different tone levels of constant intervals of the color, receiving an input of identification information of any one of the sample patches, and generating a lookup table, which is obtained by reflecting a distortion level of the reference patch, in accordance with the input identification information.
