ABSTRACT:
A pixel correction system is provided. The pixel correction system includes a dynamic range detection system that receives test pixel data and adjacent pixel data and determines whether the test pixel data is within minimum pixel characteristic data and maximum pixel characteristic data of the adjacent pixel data. For example, if the pixel characteristic data is intensity, the dynamic range detection system detects bad pixels by identifying those pixels having an intensity value that is greater than the maximum intensity value of an adjacent pixel, or less than the minimum intensity value of an adjacent pixel. A dynamic range correction system coupled to the dynamic range detection system adjusts the test pixel data if the test pixel data is not within the maximum pixel characteristic data and the minimum pixel characteristic data, such as by setting the test pixel data equal to the maximum pixel characteristic data if the test pixel data is greater than the maximum pixel characteristic data, and by setting the test pixel data equal to the minimum pixel characteristic data if the test pixel data is less than the minimum pixel characteristic data.
