When we buy projectors, we often see the word keystone correction, so what exactly does it mean? If you want the projector to project a normal picture, it is best to be relatively perpendicular to the projected object. However, in the actual operating environment, it is completely impossible to achieve a perfect projection angle due to lifting restrictions and site restrictions, so the keystone correction function came into being.
Characteristics of keystone function
At present, the mid-to-high-end projectors on the market are basically equipped with the keystone correction function. Generally speaking, there are basically two types of keystone correction, optical keystone correction and digital keystone correction. At present, most projector products basically use digital one. A variety of methods support the vertical keystone correction function, that is, the projector can adjust its height in the vertical direction, and the resulting trapezoid can be used to correct the trapezoid in the vertical direction to make the picture rectangular, which is convenient for the user.
In addition to making vertical correction, many manufacturers have also developed horizontal correction technology, which is the same as vertical correction. Horizontal keystone correction technology is also a digital technology. Generally, software is used to correct the image to avoid horizontal Distortion of the direction image.
Summary
Keystone correction is an essential function in daily use of the projector. Most of these functions are miniature projector products, because this product has more flexibility and different placement positions, you can use trapezoid The correction technique avoids the problem of distortion and is very practical.
