Title: Tomoyuki Kurashige: Innovator in Image Pickup Technology
Introduction
Tomoyuki Kurashige is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of image pickup technology, holding a total of 5 patents. His work focuses on enhancing the capabilities of image pickup apparatuses, particularly in generating both motion pictures and still images.
Latest Patents
One of Kurashige's latest patents is an image pickup apparatus and method of controlling the same. This innovative apparatus is designed to generate both motion pictures and still images. In the still imaging mode, the amount of exposure is increased compared to the motion picture imaging mode, ideally set to twice as large. The apparatus features a mechanism where electric charges are swept out from a CCD by an exposure control, which occurs simultaneously with the closing of a diaphragm to adjust the exposure amount. In cases where there is an error in the diaphragm's closing operation, the exposure amount is set to a predetermined design value. Furthermore, the apparatus corrects the gain for the video signal based on the difference between the design value and the actual measured exposure. In the motion picture mode, adjustments are made to the diaphragm and electronic shutter speed to prevent flicker under fluorescent lighting, with the adjusted speed being capable of reaching 1/100 sec.
