摘要： Embodiments are directed to devices and methods including a time-of-flight sensor and a camera. In one embodiment, a device is provided that includes a time-of-flight sensor, distance estimation circuitry, a camera, and processing circuitry. The time-of-flight sensor transmits an optical pulse signal and receives return optical pulse signals corresponding to portions of the transmitted optical pulse signal reflected by an object. The distance estimation circuitry estimates a minimum distance to the object based on a time between transmitting the optical pulse signal and receiving a first portion of the return optical pulse signals, and estimates a maximum distance to the object based on a time between transmitting the optical pulse signal and receiving a second portion of the return optical pulse signals. The processing circuitry controls a focus distance and an aperture setting of the camera based on the estimated minimum and maximum distances to the object.
