Abstract:
PURPOSE: A chipset for generating color transform coefficient and a method for controlling the same, and an apparatus for improving the quality of a picture of an HDTV system using the same are provided to easily improve color representation characteristics of an HDTV. CONSTITUTION: A TV signal receiving unit(12) receives digital broadcasting image signals transmitted from a broadcasting station. A preprocessing unit(18) adjusts the size of an image to fit for an actual size of a display device, or executes basic image transform. A color transform coefficient generating chipset(20) generates a color transform coefficient for obtaining the optimum quality of the image of a digital TV and an HDTV. A postprocessing unit(22) transforms the image by using the color transform coefficient obtained from the color transform coefficient generating chipset and a color preference data coefficient obtained from a user. An RGB display unit(16) displays the transformed RGB image on a screen.
Abstract:
PURPOSE: A device for improving image illumination characteristics and picture quality of a digital camcorder using a color display model is provided to enable a process of obtaining an image by a digital camcorder to have visual features of human being, and to use a color display model applier for an inputted image of the digital camcorder, thereby storing high-quality images and compensating distorted images. CONSTITUTION: A CCD image input unit(100) obtains an inputted image of a digital camcorder. An operational mode controller(200) performs a color display operational mode for applying a color display model relating to the inputted image, and transmits color temperature. A color display model applier(300) carries out an adaptation process corresponding to various illuminations, adapts the inputted image to the transmitted color temperature, and converts the adapted image into a visualized image. A color region controller(400) controls color regions of image data converted by the applier(300). An image storage(500) stores the image whose color regions are controlled as an output image of the digital camcorder.

PURPOSE: A constant luminance controller of an HDTV and a method for generating and outputting constant luminance are provided to find a constant luminance value close to the color of the original image to produce images with high picture quality. CONSTITUTION: A constant luminance controller of an HDTV includes a luminance controller(1), a luminance comparator(104), and a signal converter(106). The luminance controller generates and stores a look-up table in which a predetermined constant luminance value of an image with high picture quality and a reference luminance value of a general image are contrasted with each other. The luminance comparator compares the reference luminance value with the luminance value of an input image. The signal converter extracts a constant luminance value corresponding to the reference luminance value when the luminance values compared with each other are similar to each other and converts the image into RGB signals using the extracted constant luminance value.
