Latest Patents

Ji Soo Lee's latest patents include innovative methods and apparatuses that improve optical performance in imaging devices. One of his notable inventions is a method and apparatus providing an optical guide in image sensor devices. This invention involves a device and method for providing an optical guide of a pixel to guide incoming light to and from a photo-conversion device, thereby improving optical crosstalk immunity. The optical guide features an optically reflecting barrier formed as a trench filled with a material that produces reflection. This trench fill material may have an index of refraction that is less than that of the surrounding layers, creating a light reflective structure.

Another significant patent is for scene illumination adaptive lens shading correction for imaging devices. This invention encompasses methods, apparatuses, and systems for scene adaptive lens shading correction. It involves storing one or more gain adjustment surfaces calibrated to a reference illuminant type, as well as scene adjustment surfaces that vary based on the illuminant type. The imaging device can define these surfaces for each color channel of the image sensor, allowing for enhanced image processing based on the determined illuminant type.
