Problems solved by technology

However, in the above-mentioned auto-focusing process, the detection of the object distance by the camera device is not accurate, so a relatively fine picture cannot be captured, which not only increases the operation time of the user, but also reduces the user experience.

Embodiment 1

[0029] According to one aspect of the present invention, a camera device is provided, the camera device includes a camera, further, as figure 1 As shown, the camera 100 also includes:

[0030] The ultrasonic transmitting module 101 has a first fixed distance d between the camera, and the ultrasonic transmitting module 101 is used to transmit ultrasonic waves toward the object to be photographed;

[0031] The ultrasonic receiving module 103 has a second fixed distance l between the ultrasonic transmitting module 101, and the ultrasonic receiving module 103 is used for receiving reflected ultrasonic waves reflected by the object to be photographed;

[0032] The calculation module 105 is used to calculate the time difference between the time when the ultrasonic receiving module receives the reflected ultrasonic waves and the time when the ultrasonic transmitting module emits ultrasonic waves towards the object to be photographed, and according to the time difference, the first fi...

Embodiment 2

[0072] According to another aspect of the present invention, a camera method is also provided, which is applied to the above-mentioned camera device, such as Figure 7 As shown, the camera method includes:

[0073] Step S701, acquiring the emission time when the ultrasonic emitting module emits ultrasonic waves toward the object to be photographed;

[0074] Step S703, obtaining the receiving time when the ultrasonic receiving module receives the reflected ultrasonic;

[0075] Step S705, calculate the time difference between the receiving time and the transmitting time, and according to the time difference, the first fixed distance d between the ultrasonic transmitting module and the camera, and the second fixed distance l between the ultrasonic receiving module and the ultrasonic transmitting module, Calculate the first distance s between the camera and the object to be photographed and the first included angle between the central axis of the camera and the line between the c...

Abstract

The invention provides an imaging device and an imaging method. The imaging device comprises: an ultrasonic transmitting module having a first fixed distance from the camera for transmitting ultrasonic waves toward an object to be photographed; an ultrasonic receiving module having a second fixed distance from the ultrasonic transmitting module , used to receive the reflected ultrasonic waves reflected by the object to be photographed; the calculation module is used to calculate the time difference between the reception time of receiving the reflected ultrasonic waves and the emission time of the ultrasonic waves emitted toward the object to be photographed, and according to the time difference, the first fixed distance, and the second fixed distance Distance, calculate the first distance between the camera and the object to be photographed and the first angle between the central axis of the camera and the line between the camera and the object to be photographed, and obtain the position information of the object to be photographed relative to the camera; focus shooting The module is used to control the camera to focus and shoot the object to be photographed according to the location information. The invention detects the position information of the photographed object more accurately, and improves the user experience.

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 ...
