Title:
IMAGING DEVICE, ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/188387
Kind Code:
A1
Abstract:
The present invention pertains to an imaging device and an electronic device enabling highly accurate adjustment of a focal position and a camera shake correction position. The device comprises: a lens for collecting imaging subject light; an imaging element for photoelectrically converting the imaging subject light from the lens; a circuit substrate including a circuit for externally outputting a signal from the imaging element; an actuator for driving the lens in at least one direction from among X-axis, Y-axis, and Z-axis directions in accordance with a pulse width modulation (PWM) waveform; and a detector for detecting a magnetic field generated by a coil included in the actuator. The actuator drives the lens to move the focal point or drives the lens to reduce the effects of camera shake. The present invention can be applied to an imaging device.
