no. 1 example

[0034] see figure 1 , propose the first embodiment of the focusing method of the imaging device of the present invention, the focusing method includes the following steps:

[0035] Step S101: start video recording

[0036] Step S102: Collect sound during shooting

[0037] The camera device uses at least two microphones, preferably a microphone array composed of a plurality of microphones, to collect sound.

[0038] Step S103: Judging whether there is a target sound matching the pre-stored sound among the collected sounds

[0039] A person's voice segment is pre-recorded or obtained in the camera device, and the sound segment is analyzed to extract the acoustic features of the sound segment and store it. The imaging device samples the collected sound in real time or regularly, and analyzes whether there is a target sound matching the pre-stored sound in the collected sound, if there is a target sound, then enter step S104; if there is no target sound, then keep The current ...

[0061] see image 3 , propose the second embodiment of the focusing method of the imaging device of the present invention, the focusing method includes the following steps:

[0062] Step S201: start video recording

[0063] Step S202: Collect sound during shooting

[0064] Step S203: Judging whether there is a target sound matching the pre-stored sound among the collected sounds

[0065] If there is a target sound, go to step S204; if there is no target sound, go to step S205.

[0066] Step S204: Focus on the target sound source that emits the target sound

[0067] Step S205: Focus on any sound source

[0068] When the sound source is the only sound source, locate the only sound source, and control the camera to focus on the positioning direction of the sound source; when there are multiple sound sources, separate the multiple sound sources, And select any sound source for positioning, and control the camera to focus on the positioning direction of the sound source. This...

Abstract

The invention discloses an imaging device and a focusing method thereof. The focusing method includes the steps of: collecting sound during the shooting process; judging whether there is a target sound matching the pre-stored sound in the collected sound; Focusing is performed on a target sound source emitting the target sound. Therefore, by collecting sound, separating sound, and matching sound, the target sound and the corresponding target sound source are identified, and the target sound source is automatically focused, and finally the tracking and shooting of the tracking target through sound is realized, even if the tracking target is constantly Real-time tracking and shooting can also be achieved when switching or constantly moving.

Description

technical field [0001] The present invention relates to the technical field of imaging, in particular to an imaging device and a focusing method thereof. Background technique [0002] The traditional focusing method of the camera device is usually manual focusing, in which the user selects the focus point and then focuses on the focus point. Manual focus is cumbersome and inefficient, especially when the target is constantly changing or moving, manual focus cannot achieve real-time tracking and shooting. Although there is also an auto-focus method in the prior art, the existing auto-focus cannot realize tracking and shooting of a specific target. Contents of the invention [0003] The main purpose of the present invention is to provide an imaging device and its focusing method, aiming to perform automatic focusing through sound, so as to realize tracking and shooting of a tracking target. [0004] In order to achieve the above object, the present invention proposes a foc...
