Shifting Function of the Lens of Home Cinema 1080p Projector

Lens shifting is the projection image that can move up or down, left or right, while keeping the projector fixed. If you do not have any shifting function of the lens, you will need to take extreme care to position accurately in the projector to throw its fixed angle requirements. This makes it easier to have a large projector in what you want and adjust the lens to make the image perfect for the screen. Although horizontal lens shifting is usually not vertical in its wide range, it allows some movement, which is critical.

If the home cinema 1080p projector does not shift the lens, one option is to tilt the projector so that the position of the image filling screen should be placed in the projector. However, this will lead to a trapezoidal image. Therefore, the design of lens shifting function of home cinema 1080p projector can better meet the needs of the public.

Another function makes the installation easier to be displaced by the lens. Ladder correction enables home cinema 1080p projector to display images with fewer pixels, which results in projection scaling to accommodate new and smaller pixel matrices. If there is no lens shifting, sometimes it can be installed in the exact position determined by the ceiling, which is the fixed input angle of the projector. However, this often requires a height of the distance from the ceiling of the falling tube to reach the height of the preferred projection screen. Vertical lens shifting and the up and down move of the projection image makes the projector place at different heights and still correctly lit the screen. The horizontal lens shifts the projection image from one side to the other, so that the projector is placed away from the center of the screen.

On the other hand, if you plan to install your projector ceiling and throw it down onto the screen, or use a high rear shelf, a wider range of vertical lens shifts is necessary. Different displacement ranges are moderate from half-screen height by projector, and the maximum height of soldering robot is about 3 screens. If you plan to install it on the rear shelf, making the home cinema 1080p projector be at about the same height as the screen projector only needs a mild lens shift range.
