Title: Xiameng Lian: Innovator in Circuit Design and Image Processing
Introduction
Xiameng Lian is a notable inventor based in Shanghai, China. He has made significant contributions to the fields of circuit design and image processing, holding a total of 2 patents. His innovative work has the potential to impact various technological applications.
Latest Patents
Lian's latest patents include a clock circuit and a method for removing fixed pattern noise. The clock circuit comprises an oscillator circuit and a power-on reset circuit. The oscillator circuit includes a current generating module and a loop oscillation module connected together. The current generating module outputs a control current to the loop oscillation module, which in turn outputs an oscillation signal with a set frequency. The power-on reset circuit provides an enabling control signal to the loop oscillation module after the power supply is activated.
The method of removing fixed pattern noise involves performing a single-frame segmented exposure on a pixel array. It includes steps such as performing a soft reset to set the reset signal of the pixel unit to an intermediate voltage and reading a differential reset signal. A hard reset is then performed to set the reset signal to a high voltage. The process continues with enabling an exposure signal to be transmitted to the floating diffusion area and reading a differential pixel transmission signal. Finally, the differential reset signal is subtracted from the differential pixel transmission signal to obtain an exposure signal with fixed pattern noise removed.
