Zhi-Ming Lu is a prominent inventor based in Sikou, Taiwan. He has made significant contributions to the field of image processing, holding three patents that showcase his innovative approach to enhancing image quality and display technology.

Latest Patents

One of his latest patents is a method and device for scaling a two-dimensional image. This scaling device for video displays incorporates a limited number of line buffers and produces stable output frames by utilizing a stable clock source to generate the output image clock. Additionally, the device features an error counter that determines the discrepancy between the ideal output line length and the actual line length. An error accumulator keeps a running total of all output line length errors and can signal when the total line error for a given frame exceeds one, indicating the need for an additional output point in the blanking area of that output line.

Another notable patent is a directional interpolation method and device for increasing the resolution of an image. This device includes an input terminal, a memory, a texture analysis module, a texture variance consistency module, and an interpolation module. The input terminal receives signals representing the pixels of the image, while the memory stores these pixels in a row direction. The texture analysis module identifies a monotone variation area by centering on a specific position. The texture variance consistency module computes all directional texture variances in the closest upper and lower rows of pixels within the monotone variation area. The interpolation module then determines the value of the pixel to be interpolated using a median filter based on the two pixels and their neighboring pixels.
