Latest Patents

One of Koren's latest patents is titled "Methods and apparatus for detecting defects in imaging arrays by image analysis." This invention involves establishing probabilities that individual pixels are defective and updating those probabilities by analyzing images acquired by the imaging arrays. The methods can detect various defect conditions, including stuck-low, stuck-high, high-sensitivity, low sensitivity, hot, and defect-free conditions. Additionally, more complicated defect conditions can also be identified. The apparatus for detecting defective pixels can be integrated with a camera or other imaging devices or provided separately.

Another significant patent is "Active pixel with built-in self-repair and redundancy." This invention describes an active pixel sensor imaging device that comprises an array of pixel cells. Each pixel cell provides a pixel output signal to a signal output line associated with it. The design includes a photosensor with at least two independent portions, each having a sensor output, and separate readout circuits for each portion. These circuits generate output signals that are combined to produce the pixel output signal. The invention also includes hardware and software correction methods for defective pixels in both monochromatic and color imaging systems.
