Title: Sono Gu - Innovator in Image Processing Technology
Introduction
Sono Gu is a prominent inventor based in Ohmiya, Japan. He has made significant contributions to the field of image processing, holding a total of 8 patents. His work focuses on enhancing the quality and accuracy of digital image reproduction.
Latest Patents
Among his latest patents is an innovative image processing method and apparatus designed to achieve tone reproduction suited to the original image. This method involves storing digital image data captured by a CCD in a page memory at the pixel level. A CPU then reads this stored data to create a histogram. For images with high-density portions, a LOG conversion table is utilized to generate density data that accurately reproduces the tonality of these areas. Conversely, for fainter images, the same LOG conversion table ensures that tone reproduction is maintained up to the maximum density of the original, even when high-density portions cannot be reproduced. This technology guarantees that tone reproduction is consistently aligned with the original image.
Another notable patent is an image processing apparatus that includes image signal input means, tone means for toning the input image signal, beam generation means for producing a beam modulated by the pulse width modulated signal, and detection means for monitoring the output power of the generated beam. The tone means adjusts the output mode of the pulse width modulated signal based on the detection output, enhancing the overall image processing capabilities.
