Xiaomi foldable phone patent: front and rear cameras work together at the same time
The camera has been one of the important hardware of smartphones. In order to meet the shooting needs of users, mobile phone manufacturers have launched a lot of smartphones equipped with three or four cameras. By adding cameras, smartphones can achieve optical zoom, depth of field control, and other functions, thus greatly improving the quality of shooting pictures.
Xiaomi recently applied for a new patent for a very special foldable phone, because the front camera and rear camera of this phone can be work at the same time. The patent was submitted by Beijing Xiaomi Mobile Software Co., Ltd. to China National Intellectual Property Office. The patent was approved and officially announced on June 23, 2020.
In related technologies, the front and back sides of smartphones are usually equipped with an independent front camera and rear camera module. The front camera is generally used for self-shooting and video calling, and the rear camera is generally used for photographing. However, in order to meet the shooting needs of users, increasing the number of front cameras or rear camera will not only occupy the physical space of smartphones, but also increase the hardware costs.
The technical solution provided by the patent can include the following beneficial effects: by setting a gap on the first screen of the foldable mobile phone, when the phone is folded, it can simultaneously call the camera of the second screen and the camera of the first screen to shoot in the same direction, and it can realize multiple uses in a single direction without increasing the number of cameras of the foldable mobile phone. Each camera can enhance the shooting ability in a single direction, meet the shooting needs of users, save the layout space and reduce the layout design difficulty, reduce the hardware cost of folding mobile phones, and enhance the market competitiveness of products.
When the camera 13 of the folded mobile phone is facing the user, the cameras 14 and 15 are also facing the user. At this time, the user can call one or more of the cameras 13, 14 and 15 through the foldable mobile phone for self-shooting and video calling, and use the camera 13, 14 and 15 as the front camera at the same time.
When the camera 13 of the foldable mobile phone is facing away from the user, the user can also call one or more of the camera 13, camera 14, and camera 15 to shoot. The camera 15 is used as a rear camera at the same time, which can enhance the rear camera capability of the foldable mobile phone.
When the foldable mobile phone is folded, the gap is also used for the flash to emit light, which can enhance the exposure of the foldable mobile phone when taking photos. Especially in the dark place, the flash can instantly increase the exposure, make the shooting object brighter, and enhance the shooting effect.
