Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] In the embodiment of the present invention, when the request information for starting a video call is received, the specified rotation angle value is obtained to adjust the rotation angle of the camera, so that different camera rotations can be set during the video call according to the usage habits or needs of different users. Angle; In addition, the image acquired by the camera is rotated according to the specified rotation angle value, so that the upside-down image is rotated into an upright image.

Abstract

The invention is suitable for the technical field of video calling and provides a method and a device for controlling a camera to rotate. The method includes when receiving request information for starting video calling, starting the camera; acquiring a specified rotating angle value, and controlling the camera to rotate to the specified rotating angle value; starting video calling, and acquiring an image through the camera after rotating; judging whether the acquired image needs to be rotated or not according to the specified rotating angle value, and if not, directly displaying the acquired image; if yes, rotating the acquired image by 180 degrees, and displaying the image after rotating. By the method and the device, upside-down images can be rotated to be upright images by setting different camera rotating angles according to using habits or using needs of different users and rotating the images acquired by the camera according to the specified rotating angle values during video calling.

Description

technical field [0001] The invention belongs to the technical field of video calls, in particular to a method and device for controlling the rotation of a camera. Background technique [0002] Video call refers to a communication method based on the mobile Internet, the Internet or ordinary telephone lines, and transmits human voice and images in real time through mobile terminals. Existing mobile terminals generally include a rear camera and a front camera. During a video call, images of different viewing angles are collected by switching the front camera and the rear camera. However, the viewing angle range of the images that can be collected by the front camera or the rear camera is limited. Images are acquired by rotating the mobile terminal. To sum up, the existing mobile terminal has poor flexibility in controlling the camera during a video call. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide a method for co...
