Principle of Auto Keystone Correction

The unit calculates the angle between the CCD sensor and screen for each vertical and horizontal directions. The sensor measures the distance of each area 1 to area 5 and calculates the angle used with the trigonometric function. The projector has a keystone correction table for each angle. When the angle calculated by the above method, the keystone correction is performed following to the correction table. I Area1 Area2l Area3 Area4 I Area5 The sensor has the measuring area 1 to 5.

Recommendation

We recommend not to use the projector in dusty, smoky places. Using it in dusty place may cause the poor picture quality. When using under the dusty or smoky conditions, dust may accumulate on the LCD panel and lens inside it, and may resultantly be projected on the screen together with the picture. When the above symptoms are noticed, please clean up the LCD panel and lens following to the Cleaning Method.
