Image Projection (Continued)
Correcting Trapezoidal Distortion
When the image is projected either from the top or from the bottom towards the screen at an angle, the image becomes distorted trapezoidally.The function for correcting trapezoidal distortion is called Keystone Correction.
There are the two types of the Keystone Correction.
1)The “GEOMETRIC ADJUSTMENT” method corrects trapezoidal distor- tion by specifying 4 marks on the screen.
2)The “H & V KEYSTONE” method fea- tures corrections to 2 axes (horizon- tal and vertical) based on numerical values.
