Title: Innovations of Mitsuhiko Fujio
Introduction
Mitsuhiko Fujio is a notable inventor based in Iizuka, Japan. He has made significant contributions to the field of encoding and image compression technologies. With a total of 5 patents to his name, Fujio's work has had a considerable impact on the industry.
Latest Patents
Fujio's latest patents include an encoding apparatus and an image compressing apparatus. The encoding apparatus utilizes a vector quantization encoding method to encode indexes of codewords. This method supplies a scalar quantized code of the maximum scalar product value of each code word in a code book. It also calculates the maximum scalar product value to a vector component of an input image from an image sensor, allowing for efficient output of encoded indexes. The design of the scalar product value calculating circuit in the encoding apparatus features sections composed of an analog circuit, which helps reduce the scale of the circuit and lower power consumption.
The image compressing apparatus employs a mean-separated normalized vector quantization method. This method encodes and outputs a scalar-quantized code of a mean value, a scalar-quantized code of a maximum scalar product value, and an index of the code word yielding the maximum scalar product value. When the maximum scalar product value is below a predetermined threshold, the output selecting circuit restricts the output to only the mean value code. This approach helps to minimize image degradation and significantly reduce the amount of data processed.
