What are DV camcorders all about?Written by Jakob Jelling
Since they appeared, DV or Digital Video Camcorders turned home video shooting and creation into a much easier activity than it was before. Among their many advantages, DV camcorders made it possible for every camcorder user to be able to cut and edit their videos without much difficulty as well as to enjoy a much higher video quality than before.
DV camcorders allow their users to shoot and edit without having to recur to someone else's help or even needing an extra device for it. Most DV camcorders allow users to cut images and edit right after having shot movie and by just using some of camcorder controls.
The image and sound of shots taken with DV camcorders are of an extremely higher quality than they were with older camcorders. This way, DV camcorders not only facilitate their users' job but also provide them with best quality final product they could have. Movies shot with DV camcorders can be also easily uploaded to PCs, allowing this way use of many different edition software, sending images to a friend, and any many other possibilities.
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.
