Title: Makoto Otsu: Innovator in Color Misregistration Detection
Introduction
Makoto Otsu is a notable inventor based in Vancouver, WA (US). He has made significant contributions to the field of image processing, particularly in the area of color misregistration detection and correction. With a total of 4 patents, Otsu's work has advanced the technology used in imaging systems.
Latest Patents
Otsu's latest patents include innovative methods for detecting and correcting color misregistration in image data. One of his patents describes a least squares method for color misregistration detection and correction. This method involves buffering input image data and transferring it to vector space. An examination window is established for a current pixel, allowing for the selection of foreground and background pixels. The current pixel is then analyzed to determine if it is located at the edge of a scanned object. If it is, the pixel is deemed to have color misregistration, and a correction value is determined and adjusted before being applied to the pixel value.
Another patent focuses on a vector method for color misregistration detection. Similar to the previous method, input image data is buffered and transferred to vector space. An examination window is established, and the current pixel is analyzed for color misregistration using Stokes' theorem. If the results indicate that the color misregistration exceeds a certain threshold, the pixel is identified as having color misregistration.
Career Highlights
Throughout his career, Makoto Otsu has worked with prominent companies such as Sharp Laboratories of America, Inc. and Sharp Kabushiki Kaisha Corporation. His experience in these organizations has allowed him to develop and refine his innovative techniques in image processing.
