Title: Takaaki Terasita: Innovator in Scene Brightness Measurement

Introduction

Takaaki Terasita is a notable inventor based in Minami-ashigara, Japan. He has made significant contributions to the field of imaging technology, holding a total of 4 patents. His work primarily focuses on systems that enhance the accuracy of brightness measurement in various imaging applications.

Latest Patents

One of Takaaki Terasita's latest patents is a scene brightness measuring system. This innovative system utilizes multiple light receiving elements to measure the brightness of different parts of a scene. It detects the maximum brightness (Bmax) and minimum brightness (Bmin) among the measured values. The overall scene brightness (B) is then calculated using a specific formula. This calculated brightness is crucial for controlling the aperture or shutter to achieve optimal exposure. In scenarios where the weighting coefficients for the light receiving elements are equal, the average brightness (Bmean) across the entire image is utilized.

Another significant patent is the image information input system. This system is designed for use in cameras and printers, where exposure is controlled based on a selected mode of light measuring means. This means has various modes of weighting that allow for different parts of an image to be weighted differently during light measurement. The system includes multiple photodetectors arranged in arrays, along with operating means that weight the outputs of these photodetectors in diverse ways. The appropriate weighting mode is selected based on the type of scene being captured.
