Device of processing dead pixel

Image Number 6 for United States Patent #8131111.

A dead pixel processing device is disclosed. The dead pixel processing device separates an inputted Bayer pattern image into corresponding component data; calculates the distribution (pattern) of pixels based on the median of each data; calculates a comparing value based on a component having a center pixel; outputs an external flag which informs whether there are a dead pixel and/or a hot pixel by using the comparing value; compares the values of the center pixel and adjacent pixels in the component having the center pixel; calculates a measuring value based on the center pixel; outputs an internal flag by using the measuring value; and corrects the dead pixel or the hot pixel. With the present invention, an image can be corrected by detecting a corresponding dead pixel and hot pixel.
