The present invention relates to a biodegradable and thermosensitive poly(organophosphazene) with a functional group, a preparation method thereof, and a use thereof for delivery of bioactive substances. According to the present invention, poly(organophosphazene) is a phosphagen-based polymer showing biodegradability, thermosensitivity, and sol-gel phase transition depending on temperature change, whereby when administered into a living body with bioactive substances such as drugs, the poly(organophosphazene) forms a gel-phase at body temperature to be capable of controlled release of the bioactive substances. Further, the poly(organophosphazene) has functional groups to chemically bind with bioactive substances through an ionic bond, covalent bond, or coordinate covalent bond to be capable of a sustained release of the bioactive substances due to its good binding property. Therefore, the poly(organophosphazene) is useful as a delivery material for bioactive substances.

A lens shading correction method and apparatus are provided for removing vignetting occurring in digital images due to lens shading. A white image captured by an image pickup device and an image pickup unit is separated into reference white images corresponding to color channels. A vignetting center having a maximum light intensity is estimated in each of the reference white images. Multiple reference segments on each of the reference white images are defined. A lens shading correction value corresponding to each pixel constituting the reference segments are calculated using a corresponding light intensity. A lens shading correction function corresponding to each reference segment is derived using a corresponding lens shading correction value. Vignetting of a general image received in a general image processing mode is removed, using the derived multiple lens shading correction functions.

A color interpolation method and apparatus for interpolating missing color signals for each pixel of an image sensor. The color interpolation method includes forming a difference image channel by subtracting an R or B color value from a G color value in pixels adjacent to a pixel to be interpolated, detecting the direction of an edge to which the pixel to be interpolated belongs and selecting adjacent pixels to be used for color interpolation. By calculating a weight value indicating the direction of the edge and providing the weight value to the adjacent pixels to be used for color interpolation, and using the difference image values of the adjacent pixels and the weight values, a color component missing in the pixel to be interpolated can be calculated.

Disclosed is a method for removing image noise using pattern information, which filters noise caught by a sensor during preprocessing of a compression codec, so as to increase a compression efficiency, and noise caused by the codec during post-processing of the codec, so as to obtain high quality images. The method includes the steps of: (a) carrying out region dispersion with respect to input image signals so that the image signals are dispersed with a predetermined pixel size; (b) calculating mean brightness of the input image signals and carrying out noise dispersion with respect to the input image signals; (c) switching a low frequency and a high frequency based on image signals which are subjected to the region dispersion and the noise dispersion; (d) removing noise based on a statistic after obtaining the region average with respect to the image signals having the low frequency; and (e) removing noise based on a similarity of pixels after analyzing patterns with relation to the image signals having the high frequency.
