Abstract

The embodiment of the invention discloses a ranging device. The ranging device comprises a detecting unit, an adjusting unit, a first determining unit and a computing unit, wherein the detecting unit is used for detecting a target object selected by a user from preview images acquired by a camera, and focusing the target object; the adjusting unit is used for adjusting the position of a built-in motor of the camera to obtain the contrasts corresponding to the target object when the motor is in different positions; the first determining unit is used for determining the maximum contrast value in the contrasts obtained by the adjusting unit, thereby obtaining the image distance corresponding to the maximum contrast value; the image distance is the distance between the lens of the camera and a sensor; the computing unit is used for computing the object distance between the target object and the lens according to the image distance obtained by the first determining unit. The embodiment of the invention also discloses a terminal. The distance between a shot object and the camera can be effectively obtained by adopting the ranging device and the terminal.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a distance measuring device and a terminal. Background technique [0002] When capturing an image through a camera of a smart terminal, people may need to know the distance between the subject and the camera. In the prior art, a distance measurement method is to measure the distance between the object and the camera through an external device, such as loading an auxiliary distance measurement device (such as an ultrasonic distance measurement device or a laser distance measurement device, etc.) on a smart terminal, so that The distance between the shooting object and the camera is measured by the distance measuring device. Although this method can obtain the distance between the shooting object and the camera, it requires the help of an external distance measuring device. Contents of the invention [0003] Embodiments of the present invention provide a ranging dev...
