Latest Patents
One of Wei's latest patents is titled "Method and apparatus for optimizing exposure time in image acquisitions." This invention focuses on optimizing the exposure times of regions of pixels within an image sensor array. By utilizing time interval sampling, the method analyzes luminance values from digital image signals to determine when a pixel has reached optimal exposure. This allows for the selective termination of recording subsequent signals from that pixel, preserving the optimal digital image signal.
Another significant patent is "Photo-sensor cross-section for increased quantum efficiency." This invention involves the design of photo-sensors, such as photo-diodes, with cross-sections that enhance their overall quantum efficiency. By increasing the total side-wall area and incorporating additional shallow bottom areas, the photo-junction volume near the surface is maximized. This design enables a more uniform spectral response and improves the absorption of photons, particularly blue light.
