  • Page 42: Auto-Keystone Correction

    Chassis Block Diagrams Auto-keystone Correction This projector carries out the keystone correction automatically by using a G-sensor,IC3851, on the main board. The G-sensor detects the inclination of the projector and sends data as a voltage to the A/D converter,IC3801. The A/D converter converts analoge voltage value to digital data and sends data to the system control, IC301 via the IIC bus lines.The system control, IC301, calculates the keystone correction value according to the data detected from the G-sensor by using the predefined conversion table, and always adds the proper keystone cor- rection into the projected picture automatically.
