The Development of Video-Camera Technologies: Many Innovations Behind Video Cameras Are Used for Digital Cameras and Smartphones
Abstract
The video camera is a home-use color television camera that makes it possible for anyone to take a moving picture without fine-setting adjustments. Although small in size, the video camera is an intricate system that includes a number of basic technologies, such as optical systems, imaging sensors, digital signal processing circuits, and high-density assemblies. Moreover, it must be compact, lightweight, and durable with low power consumption, low pricing, and high reliability. Therefore, developing video cameras requires a wide range of technologies. Based on technologies cultivated in preceding consumer equipment, such as TV receivers and VCRs, and using a number of newly developed technologies, the world s first single-tube camera for consumer use was developed by Toshiba, Tokyo, in 1974. Video cameras popularity grew rapidly and peaked in 1991, and, eventually, they were replaced by digital cameras and smartphones. Let s look back on the history of video-camera technology and its impact on the imaging world.
