Title: Yu-Wei Chang: Innovator in Image Compression and Calibration Technologies
Introduction
Yu-Wei Chang is a notable inventor based in Cupertino, CA, recognized for his contributions to image compression techniques and camera calibration systems. With a total of 2 patents, Chang has made significant strides in enhancing the functionality of camera systems, particularly in low-power applications.
Latest Patents
Chang'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, all stored in extreme low-voltage memory. Additionally, the method incorporates resynchronization codes to recover from bit errors during decompression.
Another significant patent is a method and system for calibrating camera devices within a vehicle vision system using a programmable calibration target device. This method includes selecting a calibration sequence with a base calibration pattern and angles, generating a calibrating target, and displaying it on a screen. The vision sensor captures images of the calibrating target, and calibration is performed based on image signal processing of the extracted features.
