Abstract: A real-time image generator is disclosed. A real-time image generator may include a first block extracting only a luminance component having a saturation, hue, and value domain from red, green and blue values of an image. A second block outputs a log summation value and pixel count value with respect to a luminance component of an overall image by using the extracted luminance component and a natural log value. A third block calculates a luminance average value of the image by using the natural log summation value and the pixel count value outputted in the second block, the third block generating a tone mapping look up table including a tone mapping operator (Ld) for each luminance range to obtain a final output image using the calculated luminance average value. The third block outputs a tone mapped red, green and blue value by multiplying a corresponding tone mapping operator (Ld) of the tone mapping look up table by a red, green and blue value of the input image.

Abstract: A method and apparatus to reconstruct high-frequency components of an input audio signal. The apparatus includes a frequency inverter to invert the frequency spectrum of the input audio signal, a band pass filter which filters out the higher frequency components of the input audio signal, a converter which shifts the frequency spectrum of the filtered signal to create a correction signal, and an adder which adds the correction signal to the input audio signal to obtain a reconstructed audio signal.

Abstract: Provided is an apparatus and method for reconstructing the high frequency part of audio signal to improve the quality of the audio signal. The apparatus includes a frequency inverter which inverts the frequency of an input signal; a band-pass filter which filters the high frequency part of the inverted signal; a converter which shifts the frequency of the filtered signal so as not to generate aliasing of the input signal and the filtered signal; and an adder which adds the shifted signal to the input signal. Therefore, hearing perception close to the original signal can be achieved.
