step S202, switching to a first camera for focusing when a focusing focal length of a second camera is less than or equal to a second macro end value of the second camera, wherein the first macro end value of the first camera is less than the second macro end value of the second camera.
Through the steps, the first camera is switched to focus when the focusing focal length of the second camera is smaller than or equal to the second micro-distance end value of the second camera, wherein the first micro-distance end value of the first camera is smaller than the second micro-distance end value of the second camera, so that the problem of poor shooting effect caused by shooting out-of-focus in the related technology can be solved, and the technical effect of improving the shooting effect is achieved.

Optionally, switching to the first camera for focusing includes: searching for a focusing focal length between the first macro end value and the second macro end value. It should be noted that, the second macro end value (i.e., the end value corresponding to the macro end value of the second camera itself) may be burned into the module of the first camera, so that the first camera searches for the focusing focal length between the first macro end value (i.e., the macro end value of the first camera itself) and the second macro end value, i.e., it is not necessary to search all the adjustable focal length ranges of the first camera itself, which is beneficial to saving the focusing time.

It should also be noted that the first switching instruction may be triggered by the camera, for example, based on the user's behavior; for example, when the focal length of the first camera is greater than the first hyperfocal length of the first camera, the shooting device is triggered to send a switching instruction according to the setting of the shooting device, and the shooting device is switched to the second camera according to the switching instruction.
Optionally, switching to the second camera for focusing includes: and searching a focusing focal length from the first hyper-focal length to a far end, wherein the far end is one end which is larger than the first hyper-focal length. It should be noted that, searching for the focusing focal length from the first hyperfocal length to the far end can save the focusing time. It should be further noted that the first hyperfocal distance may be burned into the module of the second camera, so that after the second camera is switched to the second camera, the second camera may search for the focusing focal distance to the far end based on the first hyperfocal distance.
Optionally, the method further comprises: and switching to the first camera for focusing when the focusing focal length of the second camera is larger than the first hyperfocal length and a second switching instruction is received, wherein the switched focusing focal length of the first camera is the first hyperfocal length, and the second switching instruction is used for indicating switching to the first camera. It should be noted that the second switching instruction may be triggered by the shooting device, for example, based on the user behavior.

In this embodiment, a focusing device is further provided, and the focusing device is used to implement the above embodiments and preferred embodiments, which have already been described and will not be described again. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function.

Alternative embodiments
The embodiment of the invention can be applied to mobile phone photographing scenes, and provides a method for automatically switching the camera and quickly focusing when the mobile phone is used for photographing beyond the range of module capability or the camera is actively switched.
In the embodiment of the present invention, a zoom system composed of a main camera (hereinafter referred to as a main camera, which is equivalent to the first camera in the above embodiment) and a telephoto camera (hereinafter referred to as a telephoto camera, which is equivalent to the second camera in the above embodiment) is taken as an example, and the embodiment is not limited to two zoom cameras. On the basis of not increasing hardware cost, the new method is used for solving the problems of multi-shot switching and focusing speed after scene switching, the shooting effect can be improved, and the focusing time can be shortened. The user obtains more seamless camera switching experience in the process of using the zoom system, and the purpose of clear full-focus automatic focusing is achieved.
By utilizing the characteristic that the DAC code value (hereinafter referred to as code value) of a lens (lens) is fixed when multiple cameras are used for shooting the same object distance, the code value of two object distances is added to a module for burning when burning. And the DAC is used for corresponding the analog data current of the motor with the actually used digital data of 0-1023. The DAC code value of the motor is data which can represent the magnitude of the current value for driving the lens motor, and different current values can control the motor to generate different thrust to push the lens, so that the focal length of the camera is adjusted. Therefore, the Code value may be used to characterize the position of the motor driving the lens (i.e., the position of the lens), or the Code value corresponds to the position of the motor. In addition, since different motor positions can represent the focal length change of the camera, the code value can also represent the current focusing focal length of the camera, or the code value corresponds to the focusing focal length of the camera. When a main camera (hereinafter referred to as main camera) module EEPROM is burned, the following code values are burned: the code value corresponding to the distance of 9cm from the macro end, the code value corresponding to the distance of 30cm from the tele micro end, the code value corresponding to the hyperfocal distance and the code value at infinity, wherein the burning distance of the code value at infinity of the main camera is greater than the hyperfocal distance, for example, 5 meters. When the tele module is burned, the following code values are burned: the code value corresponding to the 30cm distance of the micro-distance end, the code value of the main shooting hyperfocal distance, the code value corresponding to the hyperfocal distance and the code value at infinity, wherein the burning distance of the code value at infinity of the telephoto camera is greater than the hyperfocal distance, for example 10M.
According to the embodiment of the invention, automatic switching of the multiple camera modules and rapid focusing after switching are carried out through the code values corresponding to the lens positions. Compared with a scheme of manually switching the position of the module, the user experience can be greatly improved. Compared with the scheme of increasing the depth of field of calculation of other components, the cost and the performance consumption of the system are reduced. It should be noted that the embodiment of the present invention is not limited to the use of the bi-zoom module, and can also be applied to a system such as a tri-zoom or multi-zoom system.
Fig. 4 is a schematic diagram of a mapping relationship between focal length positions of a main camera and a telephoto camera according to an alternative embodiment of the present invention, and as shown in fig. 4, the main camera focusing range is 9cm to infinity. The tele focus range is 30cm to infinity. Burning code values corresponding to the object distances: the main shooting module: a code value corresponding to 9cm, a code value corresponding to 30cm, a code value corresponding to a hyperfocal distance, and a code value at infinity (the burning distance is greater than the hyperfocal distance, for example, 5 meters). A long-focus module: a code value corresponding to 30cm, a code value corresponding to the main shooting hyperfocal distance, a code value corresponding to the hyperfocal distance, and a code value at infinity (the burning distance is greater than the hyperfocal distance, for example, 10M).
Optionally, when the distance to the object to be focused is constant, the corresponding code value is not changed for the same module, and then there is a code correspondence relationship before different modules; the module lens position information is used for burning, and when the main shooting burning is carried out, the code information burning of the micro-distance of the long-focus camera is added. In general, to capture a more distant object, the focal length of the telephoto is longer than that of the main shooting.
When the code value is operated at the macro end of main shooting to the code value corresponding to 30cm in the main shooting, the long focus cannot be focused clearly.
Optionally, when the main camera is located at a distance beyond the code corresponding to the hyperfocal distance, the telephoto may search for the focusing focal distance from a long distance on the basis of the code value of the corresponding main camera hyperfocal distance without searching all over again, that is, without searching from a short distance again, thereby saving focusing time.
Optionally, when the long focus runs to the macro end, switching to the main shooting is performed, and then the focus focal length can be directly searched on the code corresponding to the main shooting of 30cm to 9cm, and the long-distance search is not needed, so that the focusing time is saved.
When the long focus runs to the code corresponding to the infinite remote position larger than the main shooting, if the main shooting is switched to the main shooting, the main shooting directly focuses according to the hyperfocal distance position, repeated focusing is not needed, and the imaging can be clear.
The scheme provided by the embodiment can improve the use effect of switching the multiple cameras, and can achieve the effects of reducing the focusing range and improving the focusing speed when the user switches the main camera and the long focus between different lens positions.
FIG. 5 is a block diagram of a focusing system according to an alternative embodiment of the present invention, the focusing system including: the device comprises a main shooting focusing result detection module, a long-focus focusing result detection module, an EEPROM data reading module, a result judgment module and a result implementation module. The main shooting focusing result detection module can detect a focusing focal length of the main shooting, the long-focus focusing result detection module can detect a focusing focal length of the long focus, the EEPROM data reading module can read information such as a code value from the memory, the result judgment module can judge whether to switch the camera according to the focusing result, and the result implementation module can control to execute the judgment conclusion.
Fig. 6 is a schematic flowchart of a tele focusing result processing procedure according to an alternative embodiment of the invention, as shown in fig. 6, the procedure includes:
step 1, determining a tele focusing result lens code;
step 2, reading the EEPROM to obtain codes of 9cm and 30cm of the main camera when the tele lens code is equal to the code of 30cm of the tele;
step 3, automatically switching to a main shooting mode;
step 4, searching the main camera in a code interval of 9cm and 30 cm;
and 5, searching clear points, and finishing focusing.
If the user actively switches to the main shooting at the moment, when the tele lens code is larger than the tele code corresponding to the main shooting hyper focal length (hyper) distance, the main shooting lens is directly pushed to the hyper focal length; when the tele lens code is smaller than the tele code corresponding to the main shooting super-focal length distance, the main shooting carries out common focusing search; the focusing is completed.
Fig. 7 is a schematic diagram of a main focusing result processing flow according to an alternative embodiment of the present invention, as shown in fig. 7, the flow includes:
determining a main shooting focusing result lens code, and reading an EEPROM (electrically erasable programmable read-Only memory) when a user clicks to switch to a long focus: if the Lens code of the long focus is between 9cm and 30cm, the distance is less than 30cm for prompting a user; if the Lens code of the long focus is larger than the main pickup hyper, after the long focus is cut, searching from the code corresponding to the main pickup hyper position to infinity; if the Lens code of the long focus is between 30cm and the main camera hyper, after the long focus is cut, searching is started from the code corresponding to the long focus.
