Latest Patents

Zhaojian Li's latest patents showcase his expertise in cutting-edge technologies. One of his notable inventions is the "HDR Plus with MxN-cell Image Sensor". This patent outlines a method and apparatus designed to utilize M×N-cell sensors effectively. The apparatus features multiple pixel groups, each containing M×N pixels that are color-filtered to capture a single color. The process involves capturing several frames using a short-exposure setting, merging these frames into a high dynamic range (HDR) image, and subsequently performing tone mapping to derive a low dynamic range (LDR) image, where each pixel is represented by the same number of bits.

Another key patent by Li is the "Adaptive Auto White Balancing", which elucidates systems and methods for detecting depth in semiconductor devices using test key transistors. The method consists of capturing an image, generating multiple chrominance channels, and applying homogeneous region segmentation to identify regions of interest. These regions are then projected onto eigen-illuminant images using a machine learning algorithm to determine gray color pixels within the captured image.
