Abstract: A value of CCD signal of a specific pixel and a maximum value of CCD signals of neighboring pixels, which are presented in a neighboring area of the specific pixel and are a same color component as that of the specific pixel, are extracted. In case that a value of subtracting the maximum value of CCD signals of neighboring pixels from the value of CCD signal of the specific pixel exceeds a predetermined value, it is discriminated that a pixel of white defect is presented in the specific pixel and the pixel of white defect is compensated by replacing the value of CCD signal of the specific pixel with the maximum value. In case that a value of subtracting the maximum value of CCD signals of neighboring pixels from the value of CCD signal of the specific pixel does not exceed a predetermined value, it is discriminated that a pixel of white defect is not presented in the specific pixel and the pixel of white defect is compensated by outputting the value of CCD signal of the specific pixel as it is.

Abstract: A continuous process for the preparation of copolycarbonate resins has great advantages in preparing molding materials of intricate structure or of thin-wall: the molding process may be conducted easily at a relatively low temperature; the copolycarbonate has excellent impact strength especially at a low temperature; and they have excellent melt flow, i.e. 2 to 3 times of the conventional polycarbonates. The present invention is a new polycondensation process which is carried out sequentially by using serially connected tube-type reactors to simplify the process; and enhancing the rate of reaction for an incorporation of comonomer into the polymer backbone resulting from varying Reynols Number, Linear Viscosity and Weber Number.
