In order to realize high-power optical zooming, the prior art generally adopts a multi-shooting relay zooming mode to solve the problem of miniaturization.

Although ultrahigh-definition lenses appear in the market at present, due to the problem of performance of an image signal processing ISP unit, the ultrahigh-definition multi-camera zooming function is not realized in the market all the time.

First, the utility model discloses an use the scene can be the camera, also can be other equipment for shooting, in order to realize taking the photograph input more on the hardware, the utility model discloses can use the scene that contains a plurality of camera lenses, for example including long burnt camera lens, well burnt camera lens and short burnt camera lens, this scheme can realize the free switching between long burnt camera lens, well burnt camera lens and the short burnt camera lens to realize that the superelevation is clear to take the photograph zoom function more.

Referring to fig. 1, which is a schematic structural diagram of an ultra high definition multi-camera input switching device provided in an embodiment of the present invention, the ultra high definition multi-camera input switching device includes an image signal processing ISP unit, and it can be understood that the ISP unit may be an image processor ISP for a camera, and may process an image signal at a high speed.

In order to realize the ultrahigh definition multi-camera zooming function, the scheme is provided with a switch unit, and the short-focus lens and the middle-focus lens are electrically connected to the corresponding data interfaces of the ISP unit through the switch unit. The telephoto lens is electrically connected to a corresponding data interface of the ISP unit.

It can be understood that the present solution can implement input switching among the short-focus lens, the middle-focus lens and the long-focus lens by using the switch unit according to actual shooting parameters.

In practical application, a user can adjust the parameter setting of the camera during shooting, for example, the focal length value can be adjusted, and the state of the switch unit can be set according to the state of the focal length value, so that input switching among the short-focus lens, the middle-focus lens and the long-focus lens is realized.

In some embodiments, to achieve the above input switching, the switching unit includes a first switch and a second switch, the first switch and the second switch being electrically connected; the short-focus lens is electrically connected to the corresponding data interface of the ISP unit through the first switch and the middle-focus lens is electrically connected to the corresponding data interface of the ISP unit through the second switch respectively.

The first switch and the second switch are electrically connected, and the first switch and the second switch can be communicated under a certain state. Wherein, the first SWITCH and the second SWITCH are both SWITCH switches. The SWITCH is a change-over SWITCH, and the first SWITCH and the second SWITCH are combined into a SWITCH unit to realize the switching of the input signals.

In practical applications, the ISP unit includes a plurality of data interfaces, such as a first interface, a second interface and a third interface. In some embodiments, the first interface is a MIPI0 interface, the second interface is a MIPI1 interface, and the third interface is a MIPI2 interface; in other embodiments, the data interface may also be an input interface such as SLVS-ES/LVDS/DC-CAMERA/BT1120/BT 656.

In some embodiments, the short focus lens may be electrically connected to the first interface of the ISP unit through a first switch, the intermediate focus lens is electrically connected to the second interface of the ISP unit through the second switch, and the long focus lens is electrically connected to the third interface of the ISP unit.

For example, referring to fig. 2, when the anxiety value of the input signal is in the short focus range, the switching unit is in a state of switching the short focus lens on the data interface of the ISP unit, i.e., switching on the short focus lens is achieved.

Specifically, the state of the first switch may be that one end is communicated with the short-focus lens, and the other end is communicated with the first interface, so as to connect the short-focus lens and the first interface, and implement the access of the short-focus lens signal.

For another example, referring to fig. 3, when the anxiety value of the input signal is in the middle focus range, the switching unit is in a state of turning on the middle focus lens to the data interface of the ISP unit, and the short focus lens is in an off state. That is, when the user adjusts the anxiety value from the short focus range to the middle focus range, it is necessary to switch to the middle focus lens input signal and cut off the input of the short focus lens, and at this time, the switching may be implemented by the switch unit.

Specifically, the state of the second switch may be that one end is communicated with the middle-focus lens, the other end is communicated with one end of the first switch close to the short-focus lens, at this time, the first switch and the second switch are mutually conducted, the state of the first switch may be communicated with the first interface to connect the middle-focus lens with the first interface, so as to realize the signal access of the middle-focus lens, and meanwhile, because the first switch is disconnected from the short-focus lens, the input signal of the short-focus lens cannot be received at this time, so that the short-focus lens is cut off.

For another example, referring to fig. 4, when the anxiety value of the input signal is in the telephoto range, the switch unit is in a state of turning on the telephoto lens to the data interface of the ISP unit, and the short focus lens and the middle focus lens are in off states, that is, when the user adjusts the anxiety value from the middle focus range to the telephoto range, it is necessary to switch to the telephoto lens input signal and to cut off the input of the middle focus lens and the short focus lens.

Specifically, at this time, only the telephoto lens needs to be connected to the third interface of the ISP unit, and the inputs of the intermediate-focus lens and the short-focus lens are cut off, and only the input of the telephoto lens is made at this time. For example, the disconnection mode may be to activate only the third interface without activating the first interface and the second interface.

In practical applications, the above switching can be applied to the mode of 8K resolution, because due to the limitation of the performance of the image signal processing ISP unit, only one signal is input in the 8K resolution mode, for example, the above short-focus lens, the middle-focus lens and the long-focus lens are switched, and the ultrahigh-definition multi-shot zooming function is realized.

It should be noted that the application of this embodiment is not limited to the 8K resolution mode, and may also be a scene with a higher resolution, such as a 5K resolution, a 5.2K resolution, a 5.7K resolution, and a 6K resolution, which are not described herein again.

In practical application, if the resolution is in the 4K resolution mode, the performance of the ISP unit can meet the processing requirement, and referring to fig. 5, the short-focus lens and the middle-focus lens can be connected to the data interface of the ISP unit by using the switch unit, and the long-focus lens can be connected to the data interface of the ISP unit, so that 3 paths of 4K signals can be simultaneously accessed, and simultaneously, the first interface, the second interface and the third interface are also started to receive the input signal. In addition, 3-channel simultaneous video recording and preview can be supported, and single-channel 4K fusion smooth optical zooming can also be supported.

Referring to fig. 6, it is a schematic flow chart of the method for switching the ultra high definition multi-shot input provided in this embodiment, and an execution main body of the method shown in fig. 6 may be a software and/or hardware device. The subject of execution of the present application may include, but is not limited to, at least one of the following: user equipment, network equipment, etc. The user equipment may include, but is not limited to, a computer, a smart phone, a Personal Digital Assistant (PDA), the above mentioned electronic equipment, and the like. The network device may include, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a cloud consisting of a large number of computers or network servers based on cloud computing, wherein cloud computing is one of distributed computing, one super virtual computer consisting of a group of loosely coupled computers. The present embodiment does not limit this.

The method comprises steps S101 to S102, and specifically comprises the following steps:

s101, identifying a focal value of an input signal.

It is understood that the present solution may first receive an input signal of a lens, such as an input signal of a short-focus lens, a medium-focus lens or a long-focus lens, and then identify a focal rate value of the input signal. Wherein, the focal rate value can be changed according to the operation of the user for switching the zooming by using the APP on the electronic equipment.

S102, if the focal length value is within the short-focus range, connecting a short-focus lens with a data interface of an ISP unit according to a switch unit;

when the focal length value enters a middle focal length range from a short focal length range, connecting a middle focal length lens to a data interface of an ISP unit according to a switch unit, and disconnecting the short focal length lens;

and when the focal length value enters a long focal length range from a middle focal length range, connecting the long focal length lens to a data interface of an ISP unit, and disconnecting the middle focal length lens.

It should be noted that, according to the present solution, the switching of the input signal can be automatically completed through the recognized focal rate value, so as to implement the ultra high definition multi-shot zoom function.

For example, referring to fig. 1, if the focal rate value is in the short focus range, the switch unit may be triggered to switch on the short focus lens to the data interface of the ISP unit, that is, to switch on the short focus lens.

Specifically, the state of the first switch can be automatically switched, so that one end of the first switch is communicated with the short-focus lens, the other end of the first switch is communicated with the first interface, the short-focus lens and the first interface are communicated, and the signal access of the short-focus lens is realized.

As another example, when the focal rate value enters the middle focal range from the short focal range, the data interface of the ISP unit is switched on and the short focal lens is switched off according to the switching unit, that is, when the user adjusts the anxiety value from the short focal range to the middle focal range, it is necessary to switch to the middle focal lens input signal and switch off the input of the short focal lens, and the switching may be implemented by using the switching unit.

Specifically, this scheme can automatic switch over the state of first switch and second switch for the one end intercommunication well burnt camera lens of second switch, the other end intercommunication first switch is close to the one end of short burnt camera lens, and the state of first switch can be the intercommunication first interface, in order to put through well burnt camera lens with first interface realizes the access of well burnt camera lens signal, simultaneously because first switch has disconnected with the short burnt camera lens be connected, can't receive the input signal of short burnt camera lens this moment, has carried out the cutting off of short burnt camera lens promptly.

In practical application, after the intermediate focus lens is connected to the data interface of the ISP unit according to the switch unit and the short focus lens is disconnected, the short focus lens and the intermediate focus lens may be subjected to smooth zooming processing based on a preset zooming model, so that a smooth zooming effect can be realized in the switching process of the two lenses.

As another example, when the focal length value enters the telephoto range from the intermediate focus range, the data interface of the ISP unit is turned on by the telephoto lens, and the intermediate focus lens is turned off, that is, when the user adjusts the anxiety value from the intermediate focus range to the telephoto range, it is necessary to switch to the telephoto lens input signal and to turn off the input of the intermediate focus lens and the short focus lens.

Specifically, in the scheme, only the telephoto lens needs to be automatically connected to the third interface of the ISP unit, the inputs of the medium focus lens and the short focus lens are automatically cut off, and only the input of the telephoto lens is required at the time. For example, the disconnection mode may be to activate only the third interface without activating the first interface and the second interface.

Referring to fig. 7, it is a schematic flow chart of another ultrahigh definition multi-shot input switching method provided in this embodiment, and includes steps S201 to S202, which are specifically as follows: the method comprises the following steps:

s201, connecting the long-focus lens with a data interface of an ISP unit, and connecting the short-focus lens and the middle-focus lens with the data interface of the ISP unit according to a switch unit;

and S202, carrying out fusion zooming processing on the short-focus lens, the middle-focus lens and the long-focus lens.

It can be understood that if the mode is in the 4K resolution, the performance of the ISP unit can meet the processing requirement, so that the switch unit can be automatically utilized to connect the short-focus lens and the middle-focus lens to the data interface of the ISP unit, and connect the long-focus lens to the data interface of the ISP unit, so as to implement simultaneous access of 3 paths of 4K signals, and simultaneously, the first interface, the second interface, and the third interface are also activated to receive the input signal. In addition, 3-channel simultaneous video recording and previewing can be supported, and one-channel 4K fusion smooth optical zooming can also be supported.

It should be noted that the present embodiment is not limited to the application in the 4K resolution mode, and some application scenarios with smaller resolution may be applied in the present embodiment, and are not described herein again.
