Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of a focusing method according to an embodiment of the present invention is shown.
The focusing method provided by the embodiment of the invention comprises the following steps:
step 101: a first input of a user on a shooting preview interface is received.
After entering a shooting preview interface of a terminal device camera, a user can focus through a single finger, wherein the focusing can include focusing the camera and adjusting the zoom multiple of the camera. Specifically, the first input may be an input operation in which a user presses a screen of the terminal device with a finger or presses a preset fingerprint identification area in the screen, and after the terminal device detects the first input of the user, the terminal device determines the target focusing area to focus according to the first input.
The finger performing the first input may be any specific finger previously set by the user. The user can preset specific fingers capable of focusing and adjusting the camera, when the user focuses the camera through a specific finger in advance, the user can use the specific fingers to execute first input, and the terminal equipment receives the first input and focuses according to the first input. Of course, the user may not set the finger for focusing the camera in advance, and the user may perform the first input by using any one finger.
Step 102: in response to the first input, fingerprint partition change information input by the first input is acquired.
The fingerprint partition change information includes a change from a first fingerprint partition to a second fingerprint partition. Acquiring fingerprint subarea change information input by the first input, and determining the change of the finger pressing direction according to the fingerprint subarea change information so as to determine a target focusing area for focusing. The fingerprint partition in the embodiment of the invention can be a part or all of the fingerprint area of the finger of the user.
In the process of executing the first input, the user can control the fingerprint subareas to change by adjusting the finger pressing direction, and the terminal equipment determines the fingerprint subarea change information corresponding to the fingerprint subareas, so that the target focusing area is adjusted.
Step 103: and determining a target focusing area based on the fingerprint partition change information.
Wherein the fingerprint partition change information includes a change from a first fingerprint partition to a second fingerprint partition. For example: and in the initial stage of pressing operation, the focusing frame defines an object A in the preview picture, fingerprint partition change information is generated when the finger pressing direction is changed from left-inclined finger to right-inclined finger, the focusing frame moves to the right, and the focusing frame defines an object B on the right side of the object A in the preview picture.
Wherein, the finger pressing direction may include but is not limited to: a finger tilt up, a finger tilt down, a finger tilt left, a finger tilt right, a finger flat, a finger tilt left up, a finger tilt right up, a hand tilt left down, a hand tilt right down, etc. The finger pressing directions are different, then the fingerprint subareas pressed on the screen are different, and the terminal equipment can determine the finger pressing directions through the detected fingerprint subareas. For example: if the finger inclines upwards, the contact area of the finger for performing the pressing operation and the screen is the upper part area of the finger, and the identified part of the fingerprint area is the fingerprint subarea.
Step 104: and performing focusing operation on the target focusing area.
Performing a focusing operation on the target focusing area may include, but is not limited to: and focusing the camera to a target focusing area, and automatically adjusting the shooting focal length. It should be noted that, after the focusing is completed by adjusting the shooting focal length, the user may select to accept the focusing, or may select not to accept the focusing. If the focusing is received, the subsequent shooting and shooting work storage processes can be continuously executed. And if the focusing is not accepted, backspacing operation can be executed, and the first input is executed again in the shooting preview interface to trigger the terminal equipment to focus again.
According to the focusing method provided by the embodiment of the invention, the first input of the user on the shooting preview interface is detected in the shooting process, the fingerprint subarea change information input by the first input is acquired, and the target focusing area can be determined and focusing operation can be carried out according to the fingerprint subarea change information. Therefore, when the user holds the terminal device with one hand, the first input control terminal device can be executed through a single finger to focus any area, and the user operation is facilitated.
Referring to fig. 2, a second flowchart of the focusing method according to the embodiment of the invention is shown.
The focusing method in the embodiment of the invention specifically comprises the following steps:
step 201: a first input of a user on a shooting preview interface is received.
The first input comprises a second touch input, the second touch input comprising: pressing and inputting a second area of a second finger of the user on the shooting preview interface, wherein the second area is a part or all of the finger area of the second finger; in the process of pressing the second area of the second finger on the shooting preview interface, the second touch input further includes a rotation input of the user rotating the second finger, and in the pressing process, the fingerprint partition corresponding to the second area may change, for example, the fingerprint partition may be the fingerprint partition 301, the fingerprint partition 302, the fingerprint partition 303, the fingerprint partition 304, or the fingerprint partition 305 in fig. 3. And a focusing frame is displayed on the first shooting object on the shooting preview interface. After entering a shooting preview interface of a camera of the terminal equipment, a user can focus through a single finger. Specifically, the user may perform a second touch input in any area of the screen through a second finger, or perform the second touch input on a preset fingerprint identification area of the screen, and the terminal device detects the second touch input of the second finger, and adjusts a position of the focusing frame according to the second touch input, so as to define a target focusing area and perform focusing.
Step 202: in response to the first input, fingerprint partition change information input by the first input is acquired.
The specific division of the fingerprint partition may be performed by those skilled in the art according to actual requirements, for example, the fingerprint is divided into five fingerprint partitions as shown in fig. 3, where the five fingerprint partitions are: a fingerprint section 301 corresponding to a finger-up inclined press, a fingerprint section 302 corresponding to a finger-down inclined press, a fingerprint section 303 corresponding to a finger-left inclined press, a fingerprint section 304 corresponding to a finger-right inclined press, and a fingerprint section 305 corresponding to a finger-flat press.
Wherein the fingerprint partition change information includes a change from a first fingerprint partition to a second fingerprint partition. In the embodiment of the invention, after the terminal device detects the second touch input of the second finger of the user, a focusing frame is displayed in the shooting preview interface, and the displayed focusing frame can be initially arranged in the center of the shooting preview interface. In the following description, taking a screen in which the shooting preview interface includes three people as an example, as shown in fig. 4, when a second touch input to the screen by a second finger of the user is detected, a focusing frame 401 is displayed in the shooting preview interface.
Step 203: and controlling the focusing frame to move according to the target direction associated with the fingerprint partition change information.
Referring to fig. 4, a specific manner of controlling the focusing frame to move according to the target direction associated with the fingerprint partition change information will be described. The shooting preview interface comprises A, B, C three shooting objects, when a user is ready to focus on an object A, a second finger touches the screen, a fingerprint signal is identified by a fingerprint identification module arranged below the screen, functional buttons such as a shooting button in the shooting preview interface cannot disappear temporarily, and the shooting preview interface and a focusing frame are displayed.
After fingerprint signal was discerned to the fingerprint identification module, fingerprint subregion change information is confirmed according to the fingerprint signal of discerning to with fingerprint grouping change information as signal of telecommunication transmission to terminal equipment's treater, its associated target direction is confirmed according to fingerprint subregion change information to the treater, according to the position of target direction adjustment focusing frame in shooting preview interface. For example, if the focusing frame is moved from the current position to the position where the C shooting object is located, the fingerprint partition change information corresponding to the second touch input is controlled to change from the first fingerprint partition corresponding to downward pressing of the finger to the second fingerprint partition 304 corresponding to rightward inclination of the finger, where the fingerprint partition shown in fig. 4 represents that the finger is inclined rightward in the current pressing direction, and the focusing frame is moved rightward along with the finger, and is moved to the target focusing area where the C shooting object is located.
Step 204: and determining the area framed by the focusing frame at the movement end position as a target focusing area.
In a specific implementation process, after detecting the fingerprint partition change information in the second touch input process, when it is detected that the second finger is pressed downwards, that is, when the fingerprint partition changes to a fingerprint partition corresponding to the finger pressing downwards, it may be determined that the current position of the focusing frame is the movement end position, the adjustment of the position of the focusing frame is stopped, and the area selected by the focusing frame is determined as the target focusing area. The method for determining the target focusing area by moving the focusing frame according to the target direction is more flexible and convenient for user operation.
Step 203 and step 204 are methods of determining the associated target direction according to the fingerprint partition change information, and moving the position of the focusing frame according to the target direction to determine the target focusing area. In a specific implementation process, in a case that only one focusing frame is displayed in the shooting preview interface, the target focusing area may also be determined in the following manner: receiving a first touch input of a user in a shooting preview interface, responding to the first touch input, determining fingerprint partition change information in the first touch input process, and controlling a focusing frame to move to a second shooting object associated with the fingerprint partition change information; and determining the area where the second shooting object is located as a target focusing area. Wherein the first input comprises a first touch input, the first touch input comprising: pressing and inputting a first area of a first finger of a user on a shooting preview interface, wherein the first area is a part or all of the finger area of the first finger; and in the process that the first area of the first finger is pressed on the shooting preview interface, the first touch input further comprises a rotation input of rotating the first finger by the user. During the pressing process, the fingerprint partition corresponding to the first area may change, for example, the fingerprint partition 301, the fingerprint partition 302, the fingerprint partition 303, the fingerprint partition 304, or the fingerprint partition 305 in fig. 3. The first finger and the second finger may be the same finger or different fingers, and accordingly, the first region and the second region may be the same region or different regions. The first area and the second area are fingerprint areas for detecting fingerprints of the user fingers.
One way to preferably determine the target focus area is as follows: firstly, aligning a focusing frame with a shooting object in a target focusing area; secondly, outputting an inquiry prompt; the inquiry prompt is used for inquiring whether the user receives the determination of the current target focusing area; if a confirmation instruction sent by a user is received, determining that the flow of the target focusing area is completed; if the user does not accept the determination result of the target focusing area, the user can click the return key to output an unacceptable instruction, the focusing frame is placed at the center of the shooting preview interface again, the user can control the fingerprint partition change information to change by adjusting the pressing or rotating direction of the second touch input again, so that the position of the focusing frame is adjusted, and the problem of mistaken selection of the target focusing area caused by misoperation of the user can be avoided by finally determining the target focusing area after the inquiry.
Step 205: and acquiring the pressing duration of the fourth touch input.
Wherein the first input comprises a fourth touch input. The fourth touch input includes: pressing and inputting a fourth area of a fourth finger of the user on the shooting preview interface, wherein the fourth area is a partial or whole finger area of the fourth finger; and in the process that the fourth area of the fourth finger is pressed on the shooting preview interface, the fourth touch input further comprises a rotation input of rotating the fourth finger by the user. During the pressing process, the fingerprint partition corresponding to the fourth area may change, for example, the fingerprint partition 301, the fingerprint partition 302, the fingerprint partition 303, the fingerprint partition 304, or the fingerprint partition 305 in fig. 3. The fourth finger may be the same finger as the first finger or the second finger or may be a different finger. The fourth area is a fingerprint area of a fourth detected finger fingerprint of the user.
After the user selects the target focusing area, the zoom factor of the current focusing can be further adjusted through the fourth touch input. When the fourth touch input is executed, the finger executing the second touch input does not need to leave the screen, the fourth touch input is executed again, and the terminal equipment obtains the pressing time length of the fourth touch input and adjusts the zoom multiple according to the pressing time length. It should be noted that the second touch input and the fourth touch input may be continuous operation or discontinuous operation, which is not limited in the embodiment of the present invention. Correspondingly, if the user selects the target focusing area through the first touch input, the zoom factor of the current focusing can be adjusted through the fourth touch input. The first touch input and the fourth touch input may be continuous operation or discontinuous operation, and the first finger and the fourth finger may be the same finger or different fingers.
The terminal equipment is pre-stored with the association relationship between the pressing duration and the zooming times. For example: the zoom factor can be set in direct proportion to the pressing time length, and the zoom factor is larger as the pressing time length is longer. The specific association relationship between the pressing duration and the zoom factor can be set by a technician according to actual requirements, which is not specifically limited in the embodiment of the present invention. In a specific implementation process, the setting of the association between the pressing duration and the zoom multiple is not limited, and the association between the pressing duration range and the zoom multiple may also be set.
Step 206: and adjusting the focal length of the target focusing area according to the pressing time length.
After the pressing duration is determined, the association relationship between the pressing duration and the zoom multiple is prestored in the terminal equipment, so that the first zoom multiple corresponding to the determined pressing duration can be determined through the association relationship. Specifically, a first zoom multiple associated with a pressing duration is acquired; and adjusting the focal length of the target focusing area according to the first zooming multiple. The mode of associating the pressing duration with the zooming times can accurately determine the zooming times.
If the association relationship between the pressing duration range and the zooming multiple is prestored in the terminal device, the focal length of the target focusing area can be determined in the following manner: determining a duration range to which the pressing duration belongs; acquiring a second zoom multiple associated with the duration range; and adjusting the focal length of the target focusing area according to the second zooming multiple. The mode of correlating the pressing time length range with the zooming multiple has good fault tolerance, and avoids the situation that the matched change multiple cannot be found.
Step 207: and performing focusing operation on the target focusing area.
And after the focal length of the target focusing area is adjusted, the focusing effect is displayed in the shooting preview interface, and a user can select whether to accept the focusing. If the focusing is accepted, the subsequent shooting and shooting work storage processes can be continuously executed. If the focusing is not accepted, a backspacing operation can be executed, the user backs to step 206 to execute the fourth touch input again, and the terminal device detects the pressing duration of the finger and performs zoom multiple adjustment again to execute focusing on the target focusing area.
According to the focusing method provided by the embodiment of the invention, the target focusing area is determined by detecting the second touch input of the second finger of the user; and determining the pressing time length by detecting the fourth touch input of the fourth finger and adjusting the zoom multiple of the target focusing area according to the pressing time length, thereby completing focusing. Therefore, the user can control the screen to focus through a single finger while holding the terminal equipment with a single hand, and the operation of the user is facilitated. In addition, according to the focusing method provided by the embodiment of the invention, the association relationship between the pressing duration and the zooming multiple is stored in the terminal device in advance, and the zooming multiple can be accurately determined according to the association relationship after the pressing duration is determined, so that the accuracy of adjusting the zooming multiple is ensured.
Referring to fig. 5, a third flowchart of a focusing method according to an embodiment of the present invention is shown.
The focusing method in the embodiment of the invention specifically comprises the following steps:
step 501: a first input of a user on a shooting preview interface is received.
The first input comprises a third touch input, and the shooting preview interface comprises N shooting objects. The third touch input includes: pressing and inputting a third area of a third finger of the user on the shooting preview interface, wherein the third area is a part or all of the finger area of the third finger; and in the process that the third area of the third finger is pressed on the shooting preview interface, the third touch input further comprises a rotation input of rotating the third finger by the user. During the pressing process, the fingerprint partition corresponding to the third area may change, for example, the fingerprint partition 301, the fingerprint partition 302, the fingerprint partition 303, the fingerprint partition 304, or the fingerprint partition 305 in fig. 3. After receiving a third touch input, respectively displaying N focusing frames on N shooting objects on a shooting preview interface; wherein N is a positive integer greater than 1. And a focusing frame is displayed for each shooting object in the shooting preview picture, so that a user can quickly select a target shooting object.
Still taking the example that the shooting preview interface includes three character objects as an example with reference to fig. 6, as shown in fig. 6, when a third touch input of a third finger of the user to the screen is detected, a plurality of focusing frames 601 are displayed in the shooting preview interface, and each shooting object displays one focusing frame.
Step 502: in response to the first input, fingerprint partition change information input by the first input is acquired.
Wherein the fingerprint partition change information includes a change from a first fingerprint partition to a second fingerprint partition. The specific partitioning manner of the fingerprint partition may be set by those skilled in the art according to actual requirements, and is not particularly limited in the embodiment of the present invention. The focusing method in the embodiment of the present invention is described below with reference to the fingerprint partition dividing manner shown in fig. 3.
Step 503: and highlighting the focusing frame on the fourth photographic object associated with the fingerprint partition change information.
For example: referring to fig. 6, in the third touch input process, when the fingerprint partition changes such that the finger tilts right to press the corresponding fingerprint partition 304, it is determined that the fingerprint partition has changed, change information of the fingerprint partition is acquired, a fourth shooting object associated with the change information of the fingerprint partition is determined to be an a shooting object, and a focusing frame on the a shooting object is highlighted.
Step 504: and determining the area where the fourth shooting object is located as a target focusing area.
The area where the fourth photographic subject is located is an area which can completely contain the fourth photographic subject, and the specific size of the area can be set by a person skilled in the art according to actual needs. The area where the fourth photographic subject is located is determined as a target focusing area.
One way to preferably determine the area where the fourth photographic subject is located as the target focusing area is as follows: firstly, aligning a focusing frame with a fourth shooting object; secondly, outputting an inquiry prompt; the inquiry prompt is used for inquiring whether the user receives the determination of the current target focusing area; if a confirmation instruction sent by a user is received, determining that the flow of the target focusing area is completed; if the user does not accept the determination result of the target focusing area, the user can click the return key to output an unacceptable instruction, the highlight display of the focusing frame on the fourth shooting object is cancelled, the user can control the fingerprint partition change information to change again by adjusting the pressing direction of the third touch input, and therefore the highlighted focusing frame is determined, and the problem of mistaken selection of the target focusing area caused by misoperation of the user can be avoided due to the mode of finally determining the target focusing area after inquiry.
Step 505: and acquiring the pressing duration of the fourth touch input.
Wherein the first input further comprises a fourth touch input. The fourth touch input includes: pressing and inputting a fourth area of a fourth finger of the user on the shooting preview interface, wherein the fourth area is a partial or whole finger area of the fourth finger; and in the process that the fourth area of the fourth finger is pressed on the shooting preview interface, the fourth touch input further comprises a rotation input of rotating the fourth finger by the user. After the user selects the target focusing area, the zoom factor of the current focusing can be further adjusted through the fourth touch input. And the terminal equipment acquires the pressing time length of the fourth touch input and adjusts the zooming multiple according to the pressing time length. It should be noted that the third touch input and the fourth touch input may be continuous input or discontinuous input, which is not limited in the embodiment of the present invention. The third finger and the fourth finger may be the same finger or different fingers. The third area is a fingerprint area of a third detected finger fingerprint of the user, and the fourth area is a fingerprint area of a fourth detected finger fingerprint of the user.
Step 506: and adjusting the focal length of the target focusing area according to the pressing time length.
One way to adjust the shooting focus, preferably in dependence on the pressing duration, is as follows:
firstly, determining a duration range to which the pressing duration belongs;
secondly, determining a second zooming multiple associated with the duration range;
and finally, adjusting the focal length of the target focusing area according to the second zooming multiple.
The terminal device prestores an association relationship between the duration range and the zoom multiple. For example, within the duration range t1, corresponding to the zoom factor a; the pressing time length between t1t2 corresponds to the zoom multiple B. The specific association relationship between the pressing duration range and the zoom factor can be set by a technician according to actual requirements, which is not specifically limited in the embodiment of the present invention.
The mode of preferably adjusting the focal length of the target focusing area prestores the management relationship between the pressing duration range and the zooming multiple in the terminal equipment, and has higher fault tolerance compared with the prestoring the incidence relationship between specific pressing duration and zooming multiple.
Step 507: and performing focusing operation on the target focusing area.
And after the focal length of the target focusing area is adjusted, the focusing effect is displayed in the shooting preview interface, and a user can select whether to accept the focusing. If the focusing is accepted, the subsequent shooting and shooting work storage processes can be continuously executed. If the focusing is not accepted, a backspacing operation can be executed, the user performs the fourth touch input again in the step 505 after backspacing, the terminal device detects the pressing duration of the fourth finger to perform zoom multiple adjustment again, and focusing is executed on the target focusing area.
According to the focusing method provided by the embodiment of the invention, the target focusing area is determined by detecting the third touch input of the third finger of the user; and determining the pressing time length by detecting the fourth touch input of the fourth finger and adjusting the zoom multiple of the target focusing area according to the pressing time length, thereby completing focusing. Therefore, the user can control the screen to focus through a single finger while holding the terminal equipment with a single hand, and the operation of the user is facilitated. In addition, the focusing method provided by the embodiment of the invention stores the association relationship between the pressing time range and the zooming multiple in the terminal equipment in advance, so that the corresponding zooming multiple can be found more easily after the pressing time is determined, and the focusing method has good fault-tolerant rate. Furthermore, the focusing method provided by the embodiment of the invention displays a focusing frame for each shooting object in the shooting preview interface during focusing, so that a user can quickly select a target shooting object to determine a target focusing area.
