In one embodiment, a focusing instruction is generated by receiving a single click of a screen by a user, and a display interface of an image acquired by a camera of a terminal is scanned and detected, wherein the display screen of the terminal is a touch screen, and whether the single click of the user on the display screen is received or not is scanned and detected through a sensor, and the touch screen includes but is not limited to: capacitive touch screens, piezoelectric touch screens, infrared touch screens, surface acoustic wave touch screens, and the like.
In one embodiment, when a click operation of a user on the touch screen is received, the touch coordinate of the click operation is determined through a sensor, for example, a surface acoustic wave touch screen, and when a transmitting signal and a receiving signal are not touched, the waveform of the receiving signal is identical to that of a reference waveform. When a finger or other object capable of absorbing or blocking the acoustic energy touches the screen, the acoustic energy moving upward along the finger along the X-axis is partially absorbed, reflecting that there is an attenuation gap in the received waveform, i.e., at a certain time position. And the received waveform attenuates a gap corresponding to the signal of the finger blocking part, the position of the gap is calculated, the touch coordinate controller analyzes the attenuation of the received signal, and the X coordinate is judged according to the position of the gap. And then the Y axis determines the Y coordinate of the touch point by the same process. In addition to X, Y coordinates to which a typical touch screen is responsive, the surface acoustic wave touch screen is responsive to a third axis Z-axis coordinate, i.e., a value of the amount of pressure a user can sense. The principle is calculated by the attenuation amount of the attenuation position of the received signal. Once the three axes are determined, the controller passes them to the terminal. The terminal thus determines where the user clicked on the touch screen.
In an embodiment, when the terminal determines the position of the touch screen clicked by the user, that is, determines a focused target image area, and generates a focusing prompt frame, where the focusing prompt frame is used to display the focused target image area determined by the user, and the center of the focusing prompt frame is the position clicked by the user, the generation of the focusing prompt frame may be further performed with reference to step S101.

When the fact that the user clicks a focusing function selection key is received, the fact that the user selects a focusing function selection mode based on pressing operation is determined. If it has not been detected that the user has clicked the focusing function selection key and the user has not previously set the key-based focusing function to be performed, the user selects the conventional focusing mode by default.
In one embodiment, as shown in FIG. 3, 301 is a key-based focus function selection key, which when clicked 301 by the user indicates that the key-based focus function was selected by the user, and when clicked 301 twice, indicates that the key-based focus function was turned off by the user. 302 is a selection key to select flash on, indicating that the user turns the flash on when the user clicks on 302, and turning the flash off when the flash is on and the user clicks on 302. When the user clicks 303, it indicates that the user wants to select the time for each shot, the icon of 303 is changed to three small keys of 3s, 5s and 10s, and when the user clicks one of the keys, it indicates that the user selects the time for each shot. For example, when the user clicks the 3s key, it means that when the user presses the shooting key, the terminal performs the shooting operation after 3 s; or, when the user clicks the 5s key, it means that when the user presses the photographing key, the terminal performs the photographing operation after 5 s. When the user clicks 304, it indicates that the user replaces the front and rear cameras, for example, when the terminal opens the rear camera to obtain an image, after the user clicks 304, the terminal opens the rear camera to obtain an image, and similarly, when the terminal opens the front camera to obtain an image, after the user clicks 304, the terminal opens the rear camera to obtain an image. 305 displays the images acquired by the terminal camera. 306 is a key of the user, and when the user presses 306, the terminal performs a return to the main screen operation; when the user clicks 301 to select the focusing function based on the target key, 306 is the target key, and if the user presses 306, corresponding processing is performed according to this embodiment, which is not described herein.

In an embodiment, the terminal classifies the level of the pressure value in advance, and may classify the pressure value into two levels with larger differences, for example, if the target key is touched lightly, the pressure value belongs to a first level, if the target key is pressed strongly or clicked, the pressure value belongs to a second level, and the pressure values of different levels correspond to different processes, for example, if the pressure value of the pressing operation belongs to the first level, the corresponding operation is to trigger execution of focusing control on the shooting terminal by taking the target image area as the image focusing position. The method comprises the steps of acquiring a pressure value of a pressing operation of a user on a target key, specifically acquiring the pressure value of the pressing operation of the user through a pressure sensor.
In an embodiment, fingerprint information of the pressing operation is acquired, and if the fingerprint information of the pressing operation belongs to first fingerprint information, the target image area is triggered to be executed as an image focusing position, and focusing control is performed on a shooting terminal.
In one embodiment, the terminal first establishes a fingerprint database and then performs fingerprint collection, where the collection method includes, but is not limited to: living body optical type, capacitance type and pressure sensitive type. The fingerprint to the collection is categorised, can divide into two types with the fingerprint, for example, divide into the fingerprint of thumb first type, divide into the fingerprint of forefinger second type, perhaps the user will oneself make things convenient for the finger fingerprint that presses down the operation to the button all to set up to first fingerprint type, all set up all to the second fingerprint type with all the other inconvenient finger fingerprints that press down the operation to the button. Different types of fingerprints correspond to different processing, for example, if the fingerprint information of the pressing operation belongs to the first fingerprint information, the corresponding operation is to trigger execution of focusing control on the shooting terminal by taking the target image area as an image focusing position.
In one embodiment, if the pressure value of the pressing operation belongs to the second level, returning to the main screen interface; or if the fingerprint information of the pressing operation belongs to the second fingerprint information, returning to the main screen interface.
In one embodiment, another function of the target key itself is to instruct the terminal to exit the current application interface and return to the home screen interface, so that the return to the home screen interface is performed when the pressure value of the pressing operation of the user belongs to the second level or the fingerprint information of the pressing operation belongs to the second fingerprint information.
And S204, generating a focusing frame by taking the target image area as an image focusing position.

When the focusing frame is generated, the focusing frame comprises a photometric frame, the focusing frame and the photometric frame can be separated, and the image of the shooting interface can be subjected to brightness adjustment by moving the position of the photometric frame. The focusing frame and the photometric frame are the same in shape and can be simultaneously circular, square or rhombic.
S205, if the adjustment operation of the focusing frame is received, regenerating and displaying the focusing frame according to the adjustment operation, wherein the adjustment operation comprises the following steps: a moving operation for moving the focusing frame and/or an adjusting operation for adjusting the size of the focusing frame.
In one embodiment, when the terminal completes focusing on the selected area and generates a focusing area, an adjustment of the focusing frame by the user may be received.
In one embodiment, when a user finds that the position corresponding to the focusing frame is not the position which the user wants to focus, the user can adjust the position of the focusing frame by selecting the focusing frame, namely clicking the selected focusing frame to be not placed, and then moving the selected focusing frame on the display interface; or the user can double click the focusing frame to represent that the focusing frame is selected, and then double click the position which the user wants to focus, at the moment, the focusing frame can move to the position which the user double clicks, and the center of the focusing frame is the same as the position which the user double clicks, so that the position which the user wants to focus is accurate.
In one embodiment, when the user finds that the area corresponding to the focusing frame does not conform to the size of the area desired to be focused, for example, the area desired to be focused by the user is the whole building a, and the focusing frame cannot contain the whole building a no matter how the focusing frame moves, the user may select the focusing frame to be stationary, and perform an outward expansion operation on the focusing frame by two fingers to enlarge the focusing frame; similarly, if the focusing frame is too large and is far larger than the area that the user wants to focus, the user can select the focusing frame to be fixed, and the focusing frame is reduced by performing inward contraction operation on the focusing frame through two fingers; or the user can click the frame of the selected focusing frame to be fixed, and the focusing frame is enlarged by stretching outwards or is reduced by pulling inwards.
