Abstract
The present invention provides an imaging device and an imaging method. The imaging device comprises an ultrasonic wave emitting module which has a first fixed distance with a camera and is used for emitting ultrasonic wave to a shot object, an ultrasonic wave receiving module which has a second fixed distance with the ultrasonic wave emitting module and is used for receiving the reflecting ultrasonic wave reflected by the shot object, a calculation module which is used for calculating the time difference between the receiving time of receiving the reflecting ultrasonic wave and the emitting time of emitting the ultrasonic wave to a shot object, calculating and obtaining the first distance between the camera and the shot object and the angle formed by the central axis of the camera and the connection line between the camera and the shot object, and obtaining the position information of the shot object relative to the camera, and a focus shooting module for controlling the camera to carry out focus shooting on the shot object according to the position information. According to the imaging device and the imaging method, the detection of the information of the shot object is more accurate, and a user experience is improved.
Description
technical field [0001] The present invention relates to the technical field of imaging, in particular to an imaging device and an imaging method. Background technique [0002] In recent years, with the rapid development of the mobile terminal industry, its camera function has become a standard configuration, and it affects the user experience to a certain extent. Among them, the focus function is one of the factors affecting its camera function, and seriously affects the clarity of imaging. Among them, the so-called focusing refers to the process of changing the object distance and the distance position through the zoom mechanism to make the image of the object to be photographed clear. [0003] Generally, when an existing camera device automatically focuses, it first detects the object distance to the object to be photographed, and then adjusts the displacement of the camera according to the object distance to finally achieve focusing. However, during the above-mentioned ...
