Because the decoding is realized by acquiring the effective preview frame of the two-dimensional code in the code scanning process, the performance of the camera of each terminal is different, if a fixed focusing period is set for focusing, and if the set focusing period is too long, the number of the acquired clear preview frames in unit time is less, the probability of the existence of the effective preview frames is lower, and the decoding efficiency is lower; if the set focusing period is too short, the camera may not be focused within the focusing period. According to the focusing method provided by the embodiment of the invention, a dynamic focusing period is obtained through the last focusing time and the preset factor, so that the focusing period is more consistent with the actual condition of the camera, the number of the clear preview frames obtained in unit time is more, and the effective preview frames are more easily obtained, so that the effective preview frames are more easily obtained in the code scanning process of the camera, and the code scanning decoding efficiency is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a focusing method, which comprises the steps of obtaining the focusing time length of the latest focusing in the historical focusing action of a camera, wherein the focusing time length is the difference value between the focusing starting time and the corresponding focusing success time, determining the focusing period according to the preset factor and the focusing time length, and calling an automatic focusing mode according to the focusing period to focus a target focusing object. Because the effective preview frame of the two-dimensional code needs to be acquired for decoding in the code scanning process, the more the number of the clear preview frames acquired by the camera in the code scanning process is, the easier the effective preview frame is acquired, and the easier the decoding is successful. However, there is a difference between cameras of each terminal, and if the focus period of the camera is set to a fixed period, this results in the following: firstly, the set focusing period is too long, so that the camera can repeat the process of sharpness-fuzziness in the focusing process, the number of obtained sharpness preview frames in unit time is small, the probability of existence of effective preview frames is low, and the decoding probability is low; if the time of the set focusing period is too short, the camera cannot be successfully focused in the focusing period, and a phenomenon of continuous flicker is easily caused. The focusing period is determined according to the latest focusing time length and the preset factor, so that the focusing period can better accord with the actual condition of each terminal, the focusing is easier to succeed, and the code scanning efficiency can be improved.
It should be noted that the focusing method provided by the embodiment of the present invention is applied to a process of scanning a code, and may also be applied to other similar processes, which is not specifically limited, and the following description takes a process of scanning a code as an example, where an object of scanning a code may be a two-dimensional code or a barcode. In addition, the execution subject of the focusing method provided by the embodiment of the present invention may be a program or a chip of a mobile terminal, which is not particularly limited, and the following description will take the chip as an example.
The specific flow of the focusing method provided by the embodiment of the invention is shown in fig. 1, and specifically comprises the following steps:
s101: and acquiring the focusing time length of the latest focusing in the historical focusing action of the camera, wherein the focusing time length is the difference value between the focusing starting time and the corresponding focusing success time.
The camera is a camera of the terminal, the terminal may be but is not limited to a mobile terminal, and the historical focusing action and the focusing duration of the camera may be obtained by a program or a chip of the mobile terminal and stored in a storage space of the mobile terminal.
Specifically, when a camera is turned on for focusing, the focusing start time is recorded; when focusing is completed, for example, when decoding is successful, a focusing success time is recorded. And subtracting the focusing initial time from the focusing success time to obtain a difference value, wherein the difference value is the focusing duration. The focusing success time may also be the time when the camera starts to shoot, and the focusing success time may also be obtained according to a user-defined standard, which is not specifically limited by the embodiment of the present invention.
In a specific example, before S101, the method further includes: and starting the first focusing according to the initial focusing period.
The initial focusing period may be randomly set, or may be a focusing period initially set by the system, which is not limited herein. Alternatively, other focusing periods of the same or similar models may be acquired as the initial focusing period through the network.
S102: and determining a focusing period according to a preset factor and the focusing time length.
The preset factor may be set according to actual needs, and is not specifically limited herein.
Alternatively, the focusing duration may be multiplied by a preset factor to obtain the focusing period. For example, the focusing time is 500ms, the preset factor is 120%, and the focusing period is 500 × 120% — 600 ms.
In a specific example, as shown in fig. 2, S102 may specifically include the following steps:
s1021: and if the focusing time length is greater than or equal to the time length threshold, taking the time length threshold as a focusing period.
S1022: and if the focusing time length is less than the time length threshold value, adding a preset factor to the focusing time length to obtain a focusing period.
The duration threshold may be set according to actual needs, which is not specifically limited herein, and may be, for example, 1 s.
Specifically, the chip compares the focusing time length with a time length threshold, and if the focusing time length is greater than or equal to the time length threshold, the time length threshold is used as a focusing period. For example, if the time threshold is 1s and the actual focusing time is 5s, 1s is taken as the focusing period. And if the focusing time length is less than the time length threshold value, adding a preset factor to the focusing time length to obtain a focusing period. For example, if the time threshold is 1s, the actual focusing time is 500ms, and the preset factor is 100ms, the focusing period is 500+100 to 600 ms. Optionally, if the result of adding the preset factor to the focusing time length is greater than or equal to the time length threshold, the time length threshold may be used as the focusing period, or the result may be used as the focusing period, which is not limited herein.
Comparing the focusing time length with a time length threshold, and if the focusing time length is greater than or equal to the time length threshold, taking the time length threshold as a focusing period, so that the focusing period determined each time is in a reasonable range, and the stability of each focusing is improved; if the focusing time length is less than the time length threshold value, a preset factor is added to the focusing time length to obtain a focusing period, because if the focusing time length is less than the time length threshold value, the focusing environment is favorable, the focusing process is smooth, the focusing time length is added with the preset factor to determine the focusing period, so that the using environment of each time can be balanced, the focusing period is more consistent with the using environment of the terminal, and the focusing stability is improved.
S103: and calling an automatic focusing mode according to the focusing period to focus the target focusing object.
Specifically, the chip calls an automatic focusing mode of the camera according to the determined focusing period, and focuses the target focusing object according to the focusing period. It should be understood that, when focusing on a target focusing object is successful, for example, when decoding a two-dimensional code is successful, a focusing time duration corresponding to the focusing can be obtained, and then a focusing period of a next focusing process is determined according to the focusing time duration, that is, the focusing method provided by the embodiment of the present invention is a continuous cycle process.
Compared with the prior art, the focusing method provided by the embodiment of the invention has the advantages that the focusing time length of the latest focusing in the historical focusing action of the camera is obtained, the focusing period is determined according to the preset factor and the focusing time length, and then the automatic focusing mode is called according to the focusing period to focus the target focusing object. In the code scanning process, decoding is realized by acquiring effective preview frames of the two-dimensional code, the performance of a camera of each terminal is different, if a fixed focusing period is set for focusing, and if the set focusing period is too long, the number of the acquired clear preview frames in unit time is less, the probability of the existence of the effective preview frames is lower, and the decoding efficiency is lower; if the set focusing period is too short, the camera may not be focused within the focusing period. The focusing method of the embodiment of the invention obtains a dynamic focusing period through the last focusing time length and the preset factor, so that the determined focusing period is more in line with the actual condition of the camera, and more clear preview frames are obtained in unit time, thereby the camera can more easily obtain effective preview frames in the code scanning process, and the code scanning decoding efficiency is improved.
In a specific example, as shown in fig. 3, another schematic flow chart of the focusing method according to the embodiment of the present invention specifically includes the following steps:
s201: an asynchronous thread is started.
S202: and acquiring the focusing time length of the latest focusing in the historical focusing action of the camera, wherein the focusing time length is the difference value between the focusing starting time and the corresponding focusing success time.
S203: and determining a focusing period according to a preset factor and the focusing time length.
S204: and calling back the asynchronous thread according to the focusing cycle.
S205: and the asynchronous thread calls an automatic focusing mode and focuses the target focusing object according to the focusing period.
S202 and S203 are the same as S101 and S102 described above, and are not described again here.
In S201, the asynchronous thread is a self-defined asynchronous thread, which is used to call an auto-focus mode of the system camera for auto-focus after the system background waits for a certain time. It will be appreciated that the asynchronous thread is to call the auto focus mode auto focus of the system camera after waiting for the focus period to be determined.
In S204, when the focusing period is obtained, the chip calls back the asynchronous thread. A callback refers to a specific task or method being called when some event occurs. Here, when the focus period is determined, the asynchronous thread is invoked.
In S205, when the asynchronous thread is recalled, the asynchronous thread invokes an auto focus mode of the camera, and focuses the target focused object according to the determined focus period.
By setting the asynchronous thread, the asynchronous thread can be called back after the focusing period is determined, and then the asynchronous thread calls the automatic focusing mode of the camera to focus the target focusing object, so that the automatic calling of the automatic focusing mode can be realized, and the implementation efficiency of the focusing method provided by the embodiment of the invention is improved.
In a specific example, before S103, that is, before the automatic focusing mode is invoked to focus the target focusing object according to the focusing cycle, the method further includes: and setting the preview multiple of the preview frame of the camera to be one N of the maximum supported magnification of the camera, wherein N is a positive integer.
It is understood that in the process of decoding the two-dimensional code, the preview frame is acquired for decoding. The preview multiple of the preview frame of the camera is amplified, so that the details of the two-dimensional code can be more easily obtained to a certain extent, and the decoding is convenient. Therefore, the preview multiple of the preview frame of the camera is set to be one N of the maximum supported magnification of the camera, so that the effective preview frame can be obtained more easily during decoding, and the decoding efficiency is improved. N may be set according to practical situations, and is for example 2, 3 or 4, and is not limited herein.
Optionally, the focusing durations before and after setting the N to different values may be compared, respectively, and the value with the shortest focusing duration may be selected as the value finally set by N.
In a specific example, after S103, that is, after the automatic focusing mode is invoked to focus the target focused object according to the focusing cycle, the method further includes: and acquiring the attitude change value of the camera by adopting a sensor, and re-focusing if the attitude change value is greater than or equal to a preset threshold value.
The specific sensor may be selected according to the configuration of the terminal, and is not limited herein. Optionally, the sensors may include a three-axis gyroscope, an acceleration sensor, a shock sensor, and/or a servo control protocol dome machine.
The attitude change value may include a change amount of angular velocity, a change amount of acceleration, a change amount of displacement, and/or the like. The preset threshold may be set according to actual needs, and is not particularly limited herein.
Specifically, the chip acquires a posture change value of the camera acquired by a sensor of the terminal, compares the posture change value with a preset threshold value, and performs focusing again if the posture change value is greater than or equal to the preset threshold value.
And acquiring the attitude change value of the camera through the sensor, comparing the attitude change value with a preset threshold value, and re-focusing if the attitude change value is greater than or equal to the preset threshold value. Because in the process of scanning the code, the gesture changes such as shaking or deviation of the camera are easy to occur, the decoding efficiency is influenced, and the refocusing is carried out when the gesture change value is greater than or equal to the preset threshold value, so that the camera can be rapidly refocused, the focusing time is shortened, and the decoding efficiency is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the steps contain the same logical relationship, which is within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
