APPARATUS AND METHOD OF IMPROVING IMAGE QUALITY USING HSI COLOR SPACE AND H HISTOGRAM

摘要

The present invention after conversion from LCD capacitive or LCD projection TV images in RGB space to HSI space image to an apparatus and method for improving image quality using the image histogram. Method of the present invention receives the image data of the RGB space, storing in the first frame memory; Storing in a second frame memory to convert the image data in RGB space to HSI space of the image data; H representing the image data of the transformed space to HSI histogram and classifying a R / G / B group; If there is the classification that R / G / B three groups compared to the distribution of the histogram to adjust the white balance in the color group strong side of the group, and when the distribution of the histogram is equal to the standard white balance adjusting; And is applied to the adjusted white balance and consists of the step of displaying a frame stored in the first frame memory. Thus, according to the present invention converts the image data of the RGB space to the image data of the HSI space more suitable for human visual characteristics and are classified according to the histogram according to the color characteristics of the frame to improve the image quality of the display device by adjusting the white balance can be.
