Keystone Correction

Use the following procedure to correct the snapshot of a blackboard, document, poster, photograph, or other rectangular object that is out of square because it was recorded at an angle.

Performing keystone correction on an image causes a new (corrected) version (1600 1200 pixels) to be stored as a separate file.

1.In the PLAY mode, use [￿] and [￿] to scroll through images on the monitor screen and display the one you want to correct.

2.Select the “PLAY” tab, select “Keystone”, and then press [￿].

This causes a screen that shows all of the objects in the image that qualify as candidates for keystone correction to appear.

Note that the above step is possible only when there is a snapshot displayed on the monitor screen.

3.Use [￿] and [￿] to select the candidate you want to correct.

4.Use [￿] and [￿] to select “Correct”, and then press [SET].

Select “Cancel” to exit the procedure without performing keystone correction.
