Title: The Innovations of Toshio Itoh

Introduction

Toshio Itoh is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of imaging technology, holding a total of 4 patents. His work primarily focuses on methods and apparatuses for producing high-quality prints from photographic films.

Latest Patents

One of his latest patents is a method and apparatus for producing index prints and density adjusting. This innovation allows for the compensation trends of main prints to align with those of index prints. The process involves a scanner determining an exposure compensation amount for each frame based on image data from negative films. This information is then transmitted to drive controllers, which perform exposure processes to obtain both main and index prints. Additionally, his density adjusting method automatically corrects unevenness in density during the image printing stage. By printing a uniform gray image, differences in pixel density are calculated, allowing for adjustments to be made to ensure consistent quality across prints.

Another significant patent by Itoh is a method and device for selectively printing images formed on different mediums. This invention enables the printing of images recorded on photographic films and index print images onto photographic paper, all while minimizing the size of the image printing device. The film carrier is strategically positioned to expose images on negative films and liquid crystal panels using the same light source, enhancing efficiency in the printing process.
