DRIVE SIGNAL GENERATOR AND OPTICAL SCANNING DEVICE PROVIDED WITH DRIVE SIGNAL GENERATOR, AND IMAGE DISPLAY DEVICE |
摘要 |
A drive signal generator includes: a first storage part which stores data related to a primary processing signal acquired by subjecting a linearly changing saw-tooth signal to the low-pass filter processing; a parameter decision part which decides a parameter for the notch filter processing; a filter part which generates a secondary processing signal by subjecting the primary processing signal read from the first storage unit to the notch filter processing using the decided parameter decided by the parameter decision part; a second storage part which stores data related to the secondary processing signal generated by the filter unit; and a drive signal generation part which reads the data related to the secondary processing signal with a clock having a predetermined frequency and generates the drive signal by subjecting the data related to the secondary processing signal to analog conversion.
