Title: Innovations in Image Compression by Jing-Ru Qin
Introduction
Jing-Ru Qin is a notable inventor based in Shanghai, China. He has made significant contributions to the field of image compression technology. His innovative work has led to the development of a unique image compression device and method.
Latest Patents
Jing-Ru Qin holds 1 patent for his invention titled "Image compression device and image compression method." This device includes a discrete cosine transform (DCT) circuit, a quantization noise shaping (QNS) circuit, and an encoder circuit. The DCT circuit performs a DCT on original image data to generate first data. The QNS circuit then performs QNS on block data in the first data to determine a QNS score of the first coefficient. If the QNS score is greater than zero, the first coefficient is replaced with the second coefficient, which is obtained by decreasing the absolute value of the first coefficient. Finally, the encoder circuit encodes the second data to generate compressed image data.
