Problems solved by technology

For mobile terminal equipment, the frame rate of the camera is limited, and the aperture of the camera is fixed. While increasing the frame rate of the camera, the exposure time of each frame of image will be relatively reduced. The amount will be reduced, and the quality of each frame of image will be relatively reduced, such as the video becomes blurred and the definition decreases. , it is difficult to get a smoother and clearer display screen, which reduces the user's visual experience

Embodiment 1

[0024] figure 1 It is a flowchart of a video recording method in Embodiment 1 of the present invention.

[0025] refer to figure 1 As shown, the present invention provides a video recording method. The mobile terminal includes a first camera and a second camera. The centers of the first camera and the second camera are located on the same horizontal line or vertical line. The video recording method includes:

[0026] Step 101, turn on the first camera and the second camera, and enter the video recording mode.

[0027] In the embodiment of the present invention, the first camera and the second camera may be independent of each other, that is, the first camera and the second camera have independent image sensors and ISP (Image Signal Processing, image signal processing). After the mobile terminal user selects the shooting command, the mobile terminal enters the shooting mode. The camera controller FIMC (Fully Interactive Mobile Camera, camera controller) is integrated in the m...

Embodiment 2

[0036] figure 2 It is a flowchart of a video recording method in Embodiment 2 of the present invention.

[0037] refer to figure 2 As shown, the present invention provides a video recording method, the mobile terminal includes a first camera and a second camera, the centers of the first camera and the second camera are located on the same horizontal line or vertical line and the center of the first camera and the second camera The shooting frame rate is the same, the method includes:

[0038] Step 201, turn on the first camera and the second camera, and enter the video recording mode.

[0039] In practical applications, the first camera and the second camera of the mobile terminal have independent image sensors and ISP (Image Signal Processing, image signal processing). The camera main control chip integrates a camera controller FIMC (Fully Interactive Mobile Camera, camera controller). FIMC sends a clock to the camera. After the camera receives the clock signal, the came...

Embodiment 3

[0065] image 3 It is a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0066] refer to image 3 As shown, the mobile terminal 300 of the embodiment of the present invention includes a first camera (not shown) and a second camera (not shown), the centers of the first camera and the second camera are located on the same horizontal line or vertical line, the The first camera and the second camera have the same shooting frame rate, and the mobile terminal further includes: a camera opening module 301 , a shooting module 302 , and a video file generating module 303 .

[0067] The camera opening module 301 is configured to open the first camera and the second camera and enter the video recording mode.

[0068] The photographing module 302 is configured to control the first camera and the second camera to alternately photograph images; the images have a corresponding photographing time.

[0069] A video file generating module 30...

Abstract

Embodiments of the invention provide a filming method and a mobile terminal. The mobile terminal comprises a first camera and a second camera; the filming method includes: activating the first camera and the second camera to enter a filming mode, controlling the first camera and the second camera to take images alternately, wherein each image has corresponding photographic time, and generating a film file from the images according to the photographic time; by applying the embodiments of the invention, it is possible to control the first camera and the second camera to take images alternately, and more images are taken within same time, namely, photographing frame rate is increased; the first camera and the second camera are mutually independent, the quality of taken images is unchanged, photographing frame rate is increased, and image quality is also guaranteed; the film file generated based on the images taken alternately by the first camera and the second camera provides smoother and clearer pictures, and user visual experience is improved.

Description

technical field [0001] The invention relates to the technical field of shooting, in particular to a video recording method and a mobile terminal. Background technique [0002] With the development of display technology, people pursue smoother and clearer display images to obtain better visual experience when watching videos or games. [0003] At present, in video recording, in order to obtain a smoother display screen, the method of increasing the shooting frame rate is usually adopted. The frame rate is the number of frames of images captured by the camera within one second. For example, 24 frames of images per second refer to the image sensor of the camera. Output 24 frames of image data in one second, and a high frame rate can get smoother and more realistic animation. For mobile terminal equipment, the frame rate of the camera is limited, and the aperture of the camera is fixed. While increasing the frame rate of the camera, the exposure time of each frame of image will...
