Title: Innovations by Wei-Feng Huang
Introduction
Wei-Feng Huang is a notable inventor based in Saratoga, CA, who has made significant contributions to the field of image processing and low-power camera systems. With a total of 5 patents to his name, Huang's work focuses on enhancing the efficiency and functionality of imaging technologies.
Latest Patents
Huang's latest patents include an innovative image compression technique designed for low-power, always-on camera systems. This method involves compressing and storing preview video by performing colorspace-reduction image compression on a reference frame. It generates a colorspace-reduced reference frame and determines difference blocks that represent areas of a subsequent image frame differing from the reference frame. The resulting video stream comprises a color palette, the colorspace-reduced reference frame, and a difference frame, which is stored in extreme low-voltage memory. Additionally, the patent includes a mechanism for injecting resynchronization codes into the video stream to recover from bit errors during decompression.
Another significant patent by Huang is for a camera system that utilizes PWM-activated, burst-self-refresh DRAM to reduce standby power consumption. This low-power image capture device features a first image buffer in SRAM and a second image buffer in PASR DRAM, operating together as a FIFO buffer. The device is designed to capture images efficiently while minimizing power usage, making it ideal for modern imaging applications.
