Embodiment 1

[0022] see figure 1 The method for screenshotting a terminal in Embodiment 1 of the present invention is applied to a terminal with two rear cameras, and the method includes:

[0023] Step 11: Obtain a camera instruction, and control the first camera of the terminal to perform video shooting according to the camera instruction;

[0024] Step 12: While controlling the first camera to shoot video, monitor whether the preset shooting condition of the second camera of the terminal is reached, and when the monitoring result is yes, control the second camera to adopt the same method as the first camera Taking pictures in the same viewfinder range, and obtaining a screenshot image of the video currently captured by the first camera.

[0025] In Embodiment 1 of the present invention, the method for taking screenshots of the terminal controls the first camera to shoot video while monitoring whether the second camera’s shooting conditions are met, and when the shooting conditions are m...

Embodiment 2

[0039] see figure 2 , the terminal in Embodiment 2 of the present invention includes a first camera and a second camera, and the terminal further includes:

[0040] The first processing module 21 is configured to acquire an imaging instruction, and control the first camera to perform video shooting according to the imaging instruction;

[0041] The second processing module 22 is configured to monitor whether the preset photographing condition of the second camera is reached while controlling the first camera to take video, and when the monitoring result is yes, control the second camera to adopt the same The first camera takes pictures in the same viewfinder range, and obtains a screenshot image of the video currently captured by the first camera.

[0042] In Embodiment 2 of the present invention, the terminal monitors whether the photographing condition of the second camera is met while controlling the first camera to take a video, and when the photographing condition is me...

Embodiment 3

[0055] see image 3 , the method for taking a screenshot of the terminal in Embodiment 3 of the present invention includes:

[0056] Step 31: Control the first camera for video shooting, and control the second camera for real-time focusing;

[0057] Step 32: receiving a screenshot command;

[0058] Step 33: trigger the second camera to take pictures;

[0059] Step 34: determine whether the photographed picture is clear, if so, then enter step 35, if not, then enter step 36;

[0060] Step 35: saving the photographed picture as a screenshot image;

[0061] Step 36: Obtain the camera image corresponding to the screenshot timestamp and the first three frames and the last three frames of the screenshot timestamp;

[0062] Step 37: Using the motion estimation method to combine the photographed pictures and the acquired seven camera images to synthesize a clear screenshot image and save it.

[0063] As can be seen from the above, in order to capture sufficiently clear screenshot...

Abstract

The present invention provides a terminal screenshot method and terminal. The method comprises a step of obtaining an imaging instruction and controlling the first camera of the terminal to carry out video recording according to the imaging instruction, a step of monitoring whether the preset shooting condition of a second camera is reached or not while the first camera is controlled to carry out video recording, and controlling the second camera to carry out view finding and shooting by using the same view finding range of the first camera when the monitoring result is that the preset shooting condition of a second camera is reached and obtaining the screenshot image of the current recorded video of the camera. According to the scheme, while controlling the first camera to carry out video recording, whether the shooting condition of a second camera is reached or not is monitored, when the shooting condition is reached, the second camera is controlled to carry out shooting, the image same with that in the recorded video at that time is obtained as a screenshot image, and the problem of the poor quality of the image of the screenshot obtained in the video recording process in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of video screenshots, in particular to a terminal screenshot method and a terminal. Background technique [0002] At present, when the mobile phone camera is shooting a video, it uses a frame rate of 30FPS to capture the image data of the camera sensor and present it to the user. The working principle is as follows: [0003] The optical image generated by the scene through the lens (Lens) is projected onto the upper surface of the image sensor, and then converted into an electrical signal, which is converted into a digital image signal after A / D conversion, and then sent to the digital signal processing chip (DSP) for processing. It is transmitted to the display through the data bus, so that the user can see the captured image. [0004] Generally speaking, the human eye can only distinguish 30FPS images. If it is lower than this value, there will be a feeling of freezing. Therefore, the camera captu...
