Problems solved by technology

It is not possible to adjust the focus of the scene in real time during the viewfinder process. When it is necessary to adjust the focus, first bring the mobile terminal closer, and then use the other hand to adjust the focus. The whole process may require multiple attempts to achieve an ideal focus range.

Embodiment 1

[0085] Such as image 3 As shown, the mobile terminal 300 in the first embodiment includes the following functional units:

[0086] Pressure sensor 310, including one or more, is distributed on the back of the terminal, and its sensing areas are connected to form an operable area, which is used to sense various pressure operations in the operable area after being turned on;

[0087] The camera detection unit 320 is used to detect whether the terminal camera is turned on and enters the viewfinder interface, and when it is detected that the terminal camera enters the viewfinder interface, the pressure sensor 310 is turned on to make it enter the working state;

[0088] The gesture recognition unit 330 is configured to recognize the type of the focus adjustment operation gesture when the pressure sensor 310 senses a press operation; wherein the focus adjustment operation gesture includes: focus adjustment function enabling gesture, focus zoom-in adjustment gesture, and focus zoom...

Embodiment 2

[0092] Such as Figure 4 As shown, the second embodiment provides a camera focusing processing method applied to a mobile terminal, including the following steps:

[0093] Step 401, installing a pressure sensor on the back of the mobile terminal to form an operable area on the back. Through this operable area, the user will be able to perform camera focus processing by pressing and other operations.

[0094] The number of pressure sensors is not limited, and may be one, or two or more. Since each pressure sensor has a limited sensing area, in order to increase the sensing area, facilitate user operation, and improve the accuracy of gesture recognition, multiple pressure sensors can be distributed on the back of the terminal, and the sensing areas of all pressure sensors will be Seam connectivity forms an operable area with a large area for user operations, such as Figure 5 shown.

[0095] In this step, by adjusting the distribution positions of the pressure sensors accord...

Embodiment 3

[0108] In this embodiment, in order to meet the user's usage habits and maximize the convenience of user operation, the following definitions will be made for each focus adjustment operation gesture: the focus adjustment function opening gesture is defined as: single-press slide operation; focus zoom-in The adjustment gesture is defined as a bottom-to-top sliding operation (no center point setting, the starting point is located on the lower side of the operable area, such as Image 6 shown); focus adjustment gesture, defined as a sliding operation from bottom to top (no center point setting, the starting point is located at the lower side of the operable area, such as Figure 7 shown).

[0109] The processing method for zooming in on the focus and the processing method for zooming out the focus will be described separately below.

[0110] Such as Figure 8 As shown, the focal length zoom adjustment processing method in this embodiment is specifically as follows:

[0111] St...

Abstract

The invention discloses a mobile terminal and a camera focusing processing method thereof. The method comprises the steps that a pressure sensor is installed on the back of the terminal, and a sensing area is communicated to form an operable area; all focus adjusting operating gestures are defined and set in advance; when it is detected that a camera is started and enters a framing interface, the pressure sensor is started; the focus adjusting operating gestures in the operable area are sensed, and therefore corresponding focus adjusting processing operation is conducted. By means of the mobile terminal and the camera focusing processing method thereof, a focus adjusting behavior can be conveniently conducted under the condition of a single hand, and existing repeated tentative operation for adjusting focus is optimized; meanwhile, focusing is conducted according to grades, the granularity is small, and focusing can be rapidly and accurately conducted by a user. The focusing behavior operation cannot be conducted when the camera is not started or pressure does not exist on the two sides of the mobile terminal, touch conducted by mistake does not exist during routine use, the process cannot be randomly called, and the purpose of saving electricity is achieved; the controllability of shooting is made to be more convenient and rapider on the whole by means of single-hand operation, and the user experience is promoted.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a mobile terminal and a camera focusing processing method thereof. Background technique [0002] Taking pictures has become an indispensable thing in people's life. From the scenery souvenirs when traveling to selfies and pictures, everyone wants to take beautiful photos. The existing mobile phones basically have the function of taking pictures, and there are often two The camera, the pixels of the camera may also reach the level of a professional digital camera, which is likely to replace the digital camera. [0003] However, when the current mobile terminal camera focuses, both hands need to cooperate, one hand holds the mobile terminal, and the other hand uses two fingers to slide the screen to adjust the focus. It is not possible to adjust the focus of the scene in real time during the viewfinder process. When it is necessary to adjust the focus, first bring...
