3D projector to see how far away 3D film is best

When purchasing a projector, in addition to focusing on important parameters such as brightness, resolution, and contrast of the projector, consumers should also understand the focal length of the selected projector and the possible projection distance (between the projector lens and the screen). distance).

In practical applications, in order to obtain a larger projection screen size in a small space or a short projection distance, the consumer needs to select a projector equipped with a wide-angle lens, and in the case where the projection distance of the cinema or the hall environment is far away, To get the right size picture, you need to choose a projector with a telephoto lens.

The DepthQ® HD 3D projector developed by Lightspeed Design of the United States is used as an example to illustrate the correspondence between the projection distance of the 3D projector and the horizontal and diagonal dimensions of the projected image. The DepthQ® HD 3D projector has a 1.1:1 zoom lens that calculates the maximum and minimum image sizes at a certain throw distance.
It is well known that the visual quality of an image is not only related to the original image resolution and the strength of the projector's signal processing capability, but the choice of the optimal viewing distance is also a non-negligible factor. The sign of the viewing position selection can basically be measured by the pixels that are not aware of the image.

Of course, in theory, it is not unrelated to the visual sensitivity of each person. Especially when viewing a projected image in a dark environment, there is a possibility that the difference in visual sensitivity may cause a significant difference in image perception and stereoscopic effect.
