  • Apparatus and method for estimating signal-dependent noise in a camera module
    Patent number: 8106971
    Abstract: A method and apparatus for estimating signal-dependent noise in a camera module are provided, in which an image is decomposed into high frequency components and low frequency components, a variance of noise in the image is estimated using the low frequency components, noise is eliminated from the high frequency components using the estimated noise variance, and the image is recovered using the noise-eliminated high frequency components and the low frequency components.

  • Wavelet image compression/recovery apparatus and method using human visual system modeling
    Patent number: 5754793
    Abstract: Input image data is wavelet-transformed into wavelet transformed data. First, second and third quantization values respectively corresponding to the frequency variation, background brightness and edge state of the wavelet transformed data are determined. The wavelet transformed data is quantized by using a human visual quantization value for each region corresponding to the first, second and third quantization values. The quantized data is entropy-encoded to generate compressed image data.
