Introduction

Chih-Hao Kao is a notable inventor based in Singapore, known for his contributions to the field of information handling systems. He holds a total of 10 patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on enhancing webcam technology and camera systems.

Latest Patents

One of his latest patents involves reducing image flickering of webcams. This invention describes systems and methods to mitigate image flickering caused by high UV radiation from strong light sources. The webcam features a photochromic lens that adjusts its translucency based on the UV radiation it receives. In passive methods, the lens darkens in response to high UV radiation, reducing the light received by the sensor and consequently lowering the shutter speed to minimize flicker. In active methods, an image signal processor detects flicker, while UV emitters in the webcam provide the necessary radiation to darken the lens.

Another significant patent is for a multifocal camera that utilizes a refractive insertion and removal mechanism. This camera allows for rapid focus adjustments for both near and far objects by selectively inserting or removing a refractive material between the camera lens and image sensor. This innovative approach enables instant focus adjustments, enhancing the camera's functionality. A voice coil motor or other actuator can fine-tune the focus as needed, making the camera versatile and efficient.
