Learn what CCDs areWritten by Jakob Jelling
A CCD, or a Charge Coupled Device, is a microelectronic device used to capture digital images. CCDs can work with several other digital video devices such as scanners, digital cameras, camcorders, astronomical telescopes, robots, radar images and satellite photograph among many others. The origin of CCD can be found in 1969 although it has not become widely popular until much later. This technology has allowed improvement in quality and resolution of images as well as transferring and importing from one device into another. There can be a line stated between time before CCD technology appeared and after its invention. CCDs are devices that contain elements that are sensitive to light. These photosensitive elements allow devices to read images and store them according to light information it receives. Every CCD has an integrated circuit through which it stores and accumulates image information and which will allow us to then transfer it to another device. When a CCD is exposed to an image, it will store electrical charges which will accumulate image information. In other ways, visual information on each light and color image aspect is translated into different electrical charges which will equal those light and color information pieces and this way represent it.
