Abstract:
A driving control apparatus, a device, an optical module, and a driving control method will be provided, the driving control apparatus including: an acquiring unit to acquire a detection signal depending on a detection result of sensing a position of a driving target object; a driving control unit to generate a driving signal to move the driving target object to a target position based on the detection signal; an oscillation detecting unit to detect oscillation in a signal at a predetermined object point on a signal path from the detection signal to the driving signal; and an oscillation suppressing unit to suppress oscillation of the signal path according to detection of the oscillation.
