Title: Innovations by Tsung-Nan Lin

Introduction

Tsung-Nan Lin is a prominent inventor based in San Jose, CA, known for his significant contributions to imaging technology. With a total of 12 patents to his name, Lin has developed innovative techniques that enhance image quality and printing processes.

Latest Patents

One of Lin's latest patents is an image artifact removal technique for LCP. This technique identifies screen and non-screen regions of a projected or displayed image to smooth and selectively remove moiré from the screen regions while maintaining sharpness in the non-screen regions. Each pixel in the image is classified as a screen or non-screen pixel, and surrounding pixels are examined to check the classification. A low pass filter is applied to pixels in the image, with the center of the filter selectively shifted relative to a current pixel based on the examination.

Another notable patent is focused on smoothness enhancement in laser printing through periodic modulation of halftone cells. When clustered-dot dithering is employed in laser printers, a banding effect can occur due to the interaction of the dither matrix with non-uniform line spacing. Lin's innovation involves modulating the dither matrix as it moves over the image, effectively breaking up bands of clusters and providing a visually uniform image even in lighter tones.
