<P>PROBLEM TO BE SOLVED: To supervise a source voltage with resolutions and ranges corresponding to scenes. <P>SOLUTION: A voltage corresponding to the grayscale range and grayscale width of a digital signal generated by the A/D port 20c1 of a microcomputer 20c is switched according to modes. Consequently, voltage supervision suitable to normal operation and that suitable to inspection before shipment can be performed respectively by only the A/D port 20c1 of the microcomputer 20c, so the voltage supervision for the both can be achieved with simple constitution without taking a voltage out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
