Abstract: An apparatus and method are provided to equalize a histogram using a cumulative distribution function (CDF) of an image. A model parameter estimator estimates parameters from the image using a Gaussian model. An error function storing unit stores error function values based on a Gaussian distribution.

Abstract: In the optical recording medium including a substrate having pregrooves, and a metal recording thin film, a buffering layer and a reflecting layer which are stacked in sequence on the substrate, the buffering layer is formed of one or more dyes having a refractive index (n) of 1.4 or more and an absorption coefficient (k) of 1.6 or less at a wavelength of 650 nm, and a refractive index (n) of 1.8 or more and an absorption coefficient (k) of 0.001 or more at a wavelength of 780 nm. Therefore, the optical recording medium is reproducible by a CD player and a DVD player. Also, due to a metal recording thin film layer formed on a substrate, the amplitude of a recording signal is increased and the optical reliability is also improved. Also, because of a thin buffering layer, the manufacturing costs can be reduced. Also, by adding a material whose weight is rapidly lost during decomposition to the buffering layer, the recording sensitivity and the optical reliability can be much improved.
