Abstract
The present technology relates to an imaging apparatus and an electronic apparatus that are capable of adjusting a focal position with high accuracy. There are provided a lens that collects subject light, an image sensor that photoelectrically converts the subject light from the lens, a circuit substrate including a circuit that outputs a signal from the image sensor to the outside, an actuator that drives the lens with a pulse width modulation (PWM) waveform, and a detection unit that detects a magnetic field generated by a coil included in the actuator. The detection unit detects an induced electromotive force generated by the magnetic field. In addition, the detection unit detects a position of the lens from the induced electromotive force. The present technology can be applied to an imaging apparatus.
