Title: Mitsuharu Shiokawa: Innovator in Image Processing Technology

Introduction

Mitsuharu Shiokawa is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of image processing technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and accuracy of image reading and processing devices.

Latest Patents

One of his latest patents is an image reading apparatus. This apparatus includes a light emitting element, a luminance calculating unit, a light amount setting unit, and a storing unit. The light amount setting unit, during each line period, causes the light emitting element to emit light with a gradually changing reference light amount. This reference light amount is set as a default value from a plurality of reference light amounts stored in the storing unit. The apparatus identifies a reference light amount to ensure that the luminance calculated by the luminance calculating unit remains within a predetermined range. It then sets this identified reference light amount as the default value for the next line period and stores it in the storing unit.

Another significant patent is for an image processing device and method. This device performs image processing on image data obtained by receiving light emitted from a light source and reflected from an object to be read. The image processing device includes a determination unit that assesses whether the color of each pixel in the image data falls within a predetermined correction target color range. Additionally, a correction unit is included to reduce the density of pixels that belong to this correction target color range.
