Title: Akirou Terajima: Innovator in Image Printing Technology

Introduction

Akirou Terajima is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of image printing technology, holding a total of 6 patents. His work focuses on enhancing the quality and efficiency of image printing processes.

Latest Patents

Among his latest patents is the "Image Printing Apparatus and Monitor Display Density Setting Method." This invention discloses an apparatus for printing images recorded on photosensitive film to printing paper. The apparatus exposes the image, displays it on a monitor before printing, and adjusts the image accordingly. A reference image is read by a scanner to obtain digital image data, from which a predetermined number of digital pixel data for each color of the gray component are extracted. Based on this data, the monitor is adjusted to equalize the appearance of the image on the monitor and the printed image, eliminating variations due to different sensory perceptions among operators and enabling quick adjustments.

Another significant invention is the "Digital Image Forming Apparatus." This invention allows for the formation of images with excellent finish quality using a simple and low-cost structure. Linearly polarized light transmitted through each liquid crystal cell of a liquid crystal panel is converted into circularly polarized light by a quarter-wave phase plate. This circularly polarized light is then used to expose photographic printing paper via lithium-niobate prisms, preventing the formation of patterns caused by non-transmitted light areas.
