In the late 90s, as HDTV broadcasting commenced, HDTV cameras suitable for news and general purpose work were introduced. Though they delivered much better image quality, their overall operation was identical to their standard definition predecessors. New methods of recording for ENG cameras were introduced to supplant tape. Ikegami and Avid introduced EditCam in 1996, based on interchangeable hard drives. Panasonic introduced P2 cameras. These recorded a DVCPro signal on interchangeable flash card media. Several other data based recording systems were introduced, notably XDCam from Sony, and as of 2009, it remains to be seen what will become the predominant method of camera media for professional use in the 2010s.
A CCD, or Charged Coupled Device, is the basis of nearly all consumer-grade digital video camcorders. The CCD replaces both the shutter and the film of a traditional camera. The chip that makes up the CCD is covered in millions of cells called photosites, which are extremely small cells that create a charge in response to light. This charge is then converted into a light level. Cameras using this technology save their video digitally, which means it can be played back in a variety of ways, including on a TV.
Rear-projection televisions display images on the back of the screen, with a projector that is hidden behind the glass. This gives a rear projection TV the look of a traditional television set. A downside of rear projection TV systems is that they tend to have less flexibility when it comes to your viewing angle. The view is great when you sit directly in front, but not so wonderful when you move to either side. Unfortunately, at this point in time, adjusting the cameras or the projection lens regulator is not yet possible. All is not lost, however. If your problem…
In the next couple of years, 3D camcorder success will depend on the ability to easily watch your content on the new breed of TVs, says Christopher Chute, Research Manager at IDC Worldwide Digital Imaging Solutions Group. Cameras built specifically for 3D shooting may have only a niche following, yet more cameras in the coming years will give you a choice of 3D modes and let you easily capture 3D still and video content. Another trend we'll see is more glasses-free 3D screens on cameras and camcorders, enabling easy local sharing.
