Latest Patents

Dwayne A. Campbell holds a patent for a method titled "Method of classifying and correcting image sensor defects utilizing defective-pixel information from color channels." This method focuses on classifying and correcting defects in vertical color pixel sensors by utilizing defective pixel information. The process involves defining ranges of output levels of normal pixel sensors based on exposure to dark and bright flat field light sources. By capturing dark and bright images and measuring pixel outputs, the method identifies defective pixels that fall outside the normal ranges. These defective pixels are then classified, and correction values are generated for those that can be corrected, which are stored in a calibration memory associated with the vertical color image sensor.
