Latest Patents

One of Hajime Tatsuzawa's latest patents focuses on a method of printing on a print medium. This invention segments the image output region into multiple bands, allowing for precise printing of images. When the image is printed on the final band, a moving value is calculated by subtracting the number of nozzles that have discharged ink from the total number of nozzles. This calculated moving value determines the distance the print medium is moved in the reverse direction, enhancing the printing process.

Another notable patent involves an image processing system designed to convert full-color images into pseudo-color images. This system includes an image input unit that reads full-color images and outputs multi-valued data of three primary colors. The image output unit digitizes this data and produces a pseudo-color image by controlling the total area of color dots in a unit area. It also features three-dimensional color compensation tables to correct errors between output and input colors, ensuring high-quality image reproduction.
