Embodiment Construction

[0028] As mentioned above, in the prior art, when video is recorded based on multiple cameras, the reporting of the image data of the multiple cameras works independently, that is, only the video recording request is sent to the camera corresponding to the current zoom ratio. When the user is recording a video, if the zoom ratio is adjusted, especially by sliding zoom, and the zoom ratio after adjustment corresponds to a different focal length than the zoom ratio before adjustment, it is necessary to switch the camera. Only send video recording requests to the camera corresponding to the zoom ratio after zooming. If the image data reported by the camera corresponding to the zoom ratio after zooming is abnormal or the report is delayed, the corresponding target image data cannot be obtained in time, resulting in switching The picture of the camera is not smooth.

[0029] In order to solve the above problems, in the embodiment of the present invention, when it is detected that t...

Abstract

The invention discloses a video recording method and device for multi-camera equipment, a storage medium and a terminal, and the method comprises the steps: respectively transmitting a video recordingrequest to a plurality of specified cameras when a condition that a set condition is met is detected, so as to enable the specified cameras to report image data according to the received video recording request, wherein the focal lengths of the plurality of specified cameras are different, and the set condition comprises any one of the following conditions: a video starting request is received, and the configured zoom magnification exceeds a set focal length; receiving image data reported by the plurality of specified cameras; and acquiring image data adaptive to the configured zoom magnification from the image data reported by the plurality of specified cameras as target image data. According to the scheme, when the camera is switched, the fluency of the picture can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of video recording, and in particular, to a video recording method and device, a storage medium, and a terminal of a multi-camera device. Background technique [0002] Today, with the rapid development of image technology, electronic technology is constantly iterating, especially hardware technology is promoted by increasingly sophisticated manufacturing technology, including central processing unit (Central Processing Unit, CPU), storage, camera module manufacturing (lens, The performance of hardware such as sensors, motors, etc.) is constantly improving, and the software support for high-performance hardware is also becoming more mature. From the previous single camera to the later dual camera to today's three or even four cameras, not only the number of cameras has increased, but also great progress has been made in terms of pixel support and diversified support for field of view. [0003] Us...
