On December 9th, according to the authorization announcement of the State Intellectual Property Office yesterday, Huawei has obtained a new patent for photography-related technology, which can be adjusted by opening and clenching fist gestures.
The abstract of the patent is as follows:
The embodiment of the present application provides a photo-taking method in which the electronic device can recognize the user's gesture through the front-facing camera.
When a specific gesture is recognized, a series of images are displayed in the preview box, and the size of the preview angle is graded.
For example, when the front-facing camera recognizes the gesture of opening the palm and pushing forward, the preview angle of a series of images displayed by the electronic device in the preview frame gradually increases, allowing more scenes to be presented in the preview frame.
In this way, users can adjust the preview angle and framing at the same time, which is convenient to operate and makes the shooting process more efficient.
According to the patent description, this **gesture is suitable for taking pictures and **, after detecting the open palm pushing forward, it can zoom in on the framing angle;When a fist gesture is detected, the framing angle can be narrowed out, allowing for more flexibility in the shooting scene.
