Video Camera Technologies Systematization Yasuo Takemura
Video Camera Technologies Systematization 2 Yasuo Takemura Abstract The video camera is a color television camera for consumer use that makes it possible for anyone to take, record and save a moving picture. This paper surveys developments in consumer video camera technology. Video cameras have been developed and manufactured in Japan for several decades and exported to global markets. Many kinds of video camera technologies developed in Japan have been applied to digital still cameras, mobile phones for communication, and even smartphones and tablets. Although compact in size, the video camera system includes a myriad of basic technologies covering a wide range of technical fields, including optical systems and lenses, image sensors – the key device in photoelectric conversion, digital signal processing for reproducing high-quality, highly-functional images, recording systems for recording images and high density mounting to bring it all together in a compact form. Furthermore, the video camera must also be small, lightweight, durable and energy-efficient, as well as the basic consumer requirements of low pricing and high reliability. The image sensor industry has developed into one of Japan’s most successful industries, supported by the timely and rapid advancement of semiconductor technology and accompanied by a wealth of specialized research. Japanese consumers expect high fidelity image quality, which has driven the development of high-quality television and video camera technologies through collaboration between sensor technology -

Bryan Rawlings VE3QN Great Inventions & Their Inventors … The Electric Light Bulb Thomas Edison The Telephone Alexander Graham Bell The Airplane Wilbur & Orville Wright Radiotelegraphy Guglielmo Marconi 2 But, who invented Television ? Paul Nipkow ? Vladimir Zworykin ? Alan Campbell-Swinton ? Kenjiro Takayanagi ? John Logie Baird ? Philo T. Farnsworth ? Boris Rosing ? Charles Jenkins ? Karl Friedrich Braun ? 3 The Origins of Television … All of these men played a role in the invention of television and in the early decades of the twentieth century there was great popular interest in television. But the story began late in the nineteenth century … 4 Conceptualizing Television … After the invention of the electric telegraph and the telephone some thought that images might be sent electrically by mimicking how images are transmitted from the retina to the brain. But, clearly, this would be totally impractical. A better idea was needed and Paul Nipkow supplied one … 5 Paul Nipkow … Paul Nipkow was born in Prussia in 1860 and worked as an engineer. In 1885 he patented an idea for what he called an “electric telescope” but there is no indication he ever attempted to build a device. Central to Nipkow’s concept was what has come to be called “The Nipkow Disc”. More significantly, Nipkow could be said to have introduced the concept of “scanning” – central to both mechanical and electronic television. 6 The Nipkow Disc … Ø The Nipkow Disc: A circular disc with a spiral sequence of holes. Ø A lens focuses an image onto the front of the disc and a photoelectric cell is placed behind the disc.
