Introduction

Kao-Der Chang is a notable inventor based in Taichung, Taiwan. He has made significant contributions to the field of technology, particularly in image processing and display systems. With a total of 3 patents to his name, his work reflects a commitment to advancing innovative solutions.

Latest Patents

Chang's latest patents include a "Training Method for Phase Image Generator" and a "Training Method of Phase Image Classifier." The training method for the phase image generator involves several steps. Firstly, in each iteration, a loss value is generated, which includes the phase image generator creating multiple generated phase images using a specific generation mode. Next, a phase image determiner assesses the degree of difference between the generated phase images and the original phase images. The loss value is then calculated based on this degree of difference. A selector subsequently chooses a stable loss value from the generated loss values, using the corresponding phase image generation mode as the selected mode for the phase image generator.

Additionally, his patent for a "Head-Up Display with Variable Focal Length" features a projector that emits a beam with an image. This system includes a magnifier lens module positioned along the beam's path and an array of lenses that can be adjusted between the projector and the magnifier lens module. The beam creates an inter-image after passing through the array of lenses, ultimately forming a virtual image after passing through the magnifier lens module. The position of the virtual image can be altered by adjusting the relative position between the array of lenses and the magnifier lens module.
