Embodiment 1

[0027] Please refer to figure 1 , the present invention provides an image acquisition control method to improve the focus accuracy in the process of taking pictures with an external camera, the method comprising:

[0028] Step 101, when receiving a photographing instruction from a user, sending an autofocus instruction to the camera, and starting a first timer accordingly;

[0029] In this embodiment, if the user needs to take pictures through the USB camera on the smart TV, he can open the built-in camera application of the smart TV, and the system will start the camera application in response to the user's opening operation, and will start the USB camera to enter the image acquisition state , at this time, the USB camera will continue to output the collected images to the operating system, and the camera application can present these images on the TV screen in real time. When receiving a photographing command from the user, the photographing application sends an auto-focus ...

Embodiment 2

[0034] Please refer to image 3 , on the basis of the first embodiment above, it is considered that the USB camera may not be able to focus within the first focus delay time due to continuous movement of the subject to be photographed or other reasons, so that the captured image may still be relatively blurred. In the embodiment of the present invention, the state of the focusing coil motor is used for further auxiliary judgment. When the auto focus starts, the focus coil motor inside the USB camera also starts to move. After the auto focus is completed, the focus coil motor will change from a moving state to a static state. Therefore, the present invention obtains the state of the focus coil motor through the drive interface of the USB camera. Once the state of the focus coil motor is in a static state, and the first delayed focus time has also expired, there is a very high possibility that the auto focus has been completed. , the image collected at this time will usually be...

Embodiment 3

[0042] An embodiment of the present invention provides an image acquisition control device, such as figure 2 As shown, the device is applied to a display device, which is usually a smart TV, and the basic hardware environment of the smart TV includes a CPU 22 , a memory 20 , a non-volatile memory 21 and other hardware 23 . The image acquisition control device logically includes: a photographing control unit 201 and an image acquisition unit 202, wherein the photographing control unit 201 and the image acquisition unit 202 are controlled and executed by a CPU. The device performs the following processing flow during operation:

[0043] A photographing control unit, the photographing control unit 201 sends an autofocus instruction to the USB camera when receiving a photographing instruction from the user, and starts a first timer accordingly;

[0044] In this embodiment, if you need to take pictures with the USB camera on the smart TV, you can open the built-in camera applicat...

Abstract

The invention provides display equipment, an image capturing and controlling device and an image capturing and controlling method. The device comprises a photographing control unit and an image acquisition unit. When receiving a photographing command of a user, the photographing control unit sends an automatic focusing command to an external camera and starts a first timer correspondingly. After the first timer is overtime, the image acquisition unit acquires a frame of image as a photographing image from video streaming outputted by the external camera. By the display equipment, the image capturing and controlling device and the image capturing and controlling method, focusing accuracy of the external camera during photographing can be effectively improved, and users can acquire images with good quality when photographing by the external camera.

Description

technical field [0001] The invention relates to the technical field of smart televisions, in particular to a display device, an image acquisition control device and a method. Background technique [0002] With the development of Internet technology and the continuous improvement of network speed, external cameras are widely used in video conferencing, real-time monitoring, and visual conversation and communication through social software. Recently, with the rapid development of smart TVs, TV manufacturers also use them to assemble smart TVs for various emerging applications including video calls, video recording and somatosensory games. However, because the current external camera usually does not have auto-focus function or the auto-focus function is poor, and the external camera is different from the current smart phone or even the integrated camera of the notebook computer, and the coupling degree between it and the host is low, resulting in When using an external camera...
