Title: The Innovations of Masato Teratani

Introduction

Masato Teratani is a notable inventor based in Yoro-gun, Japan. He has made significant contributions to the field of image processing technology. With a total of 2 patents to his name, Teratani's work focuses on enhancing image data processing methods.

Latest Patents

One of Teratani's latest patents is an "Image data processor and image data processing method." This invention involves storing image data of a target pixel and its peripheral pixels in memory. A most significant bit extractor circuit extracts the four most significant bits of data from each image. A histogram circuit then generates a histogram of the extracted data. Referring to this histogram, a data processor circuit replaces the image data of the target pixel with the maximum value of the number of pixels having the same level, outputting the processed data. Finally, a digit-complementing circuit converts the output data to 8-bit data. This process allows for the transformation of a regular image into one that resembles a draft-design image.

Another significant patent is the "Deficient pixel detection method and image signal processor." This invention detects deficient pixels, such as those with white or black deficiencies, and corrects the image signal to prevent the reproduction of these deficiencies. A memory circuit holds the target pixel signal and peripheral signals from adjacent pixels. A deficiency detection circuit compares the target pixel signal level with that of the peripheral signals to identify deficiencies. A deficiency correction circuit then uses information from nearby pixels to correct the signal of any detected deficient pixel.
