The technical scheme of the application is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
In order to realize high-multiple optical zooming, the problem of miniaturization is generally solved by a multi-camera relay zooming mode in the prior art.
Although ultra-high-definition lenses appear in the market at present, the ultra-high-definition multi-camera zoom function is not realized in the market at all time due to the problem of the performance of an ISP (Internet service provider) unit for processing image signals.
Firstly, the application scene of the application can be a camera or other shooting equipment, and in order to realize multi-shot input on hardware, the application can be applied to scenes comprising a plurality of lenses, such as a long-focus lens, a medium-focus lens and a short-focus lens.
Referring to fig. 1, a schematic structural diagram of an ultra high definition multi-shot input switching device according to an embodiment of the present application includes an image signal processing ISP unit, and it is understood that the ISP unit may be a camera image processor ISP, and may process image signals at a high speed.
In order to realize the ultra-high definition multi-shot zooming function, the scheme is provided with a switch unit, and the short-focus lens and the medium-focus lens are electrically connected to corresponding data interfaces of the ISP unit through the switch unit. The tele lens is electrically connected to a corresponding data interface of the ISP unit.
It can be understood that the scheme can utilize the switch unit to realize input switching among the short-focus lens, the medium-focus lens and the long-focus lens according to actual shooting parameters.
In practical application, because the user can adjust parameter setting for the camera during shooting, for example, the focus value can be adjusted, the switch unit state can be set according to the state of Jiao Lvzhi in the scheme, and input switching among the short-focus lens, the medium-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 through the second switch respectively.
It should be noted that, the first switch and the second switch are electrically connected, and in a certain state, the first switch and the second switch may be connected. Wherein, the first SWITCH and the second SWITCH are 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 change-over of 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. Wherein in some embodiments, the first interface is specifically, for example, a MIPI0 interface, the second interface is specifically, for example, a MIPI1 interface, and the third interface is specifically, for example, 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 a first interface of the ISP unit through a first switch, the mid focus lens is electrically connected to a second interface of the ISP unit through the second switch, and the long focus lens is electrically connected to a 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., the switching on of 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, thereby realizing the access of short-focus lens signals.
As another example, referring to fig. 3, when the anxiety value of the input signal is in the mid range, the switching unit is in a state of turning the mid lens on 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 mid-focus range, it is necessary to switch to the mid-focus lens input signal and cut off the input of the short-focus lens, at which time the switching can be achieved by the switching unit.
Specifically, the state of the second switch can be that one end communicates the middle-focus lens, and the other end communicates the one end that the first switch is close to the short-focus lens, and at this moment, first switch and second switch on each other, and the state of the first switch can be that the intercommunication the first interface is in order to switch on the middle-focus lens with the first interface realizes the switch-in of middle-focus lens signal, simultaneously because first switch has disconnected the connection with the short-focus lens, can't receive the input signal of short-focus lens at this moment, has carried out the cutting off of short-focus lens promptly.
Still further exemplary, referring to fig. 4, when the anxiety value of the input signal is in the tele range, the switching unit is in a state of switching the tele lens on the data interface of the ISP unit, and the short-focus lens and the mid-focus lens are in an off state, i.e., when the user adjusts the anxiety value from the mid-focus range to the tele range, it is necessary to switch to the tele lens input signal and to cut off the inputs of the mid-focus lens and the short-focus lens.
Specifically, only the long-focus lens is connected to the third interface of the ISP unit, and the input of the middle-focus lens and the short-focus lens is cut off, so that only the long-focus lens is input. The switching-off mode may be, for example, not to activate the first interface and the second interface, but to activate only the third interface.
In practical application, the above switching can be applied in the 8K resolution mode, because only one signal is input when the image signal processing ISP unit performance is limited to the 8K resolution mode, for example, the above switching among the short-focus lens, the medium-focus lens and the long-focus lens is needed, and the ultra-high definition multi-shot zoom function is realized.
It should be noted that, the application of the embodiment is not limited to the above-mentioned 8K resolution mode, but may be a scene with a larger resolution, such as a 5K resolution, a 5.2K resolution, a 5.7K resolution, and a 6K resolution, which are not described herein.
In practical application, if the performance of the ISP unit is in the mode of 4K resolution, referring to fig. 5, the switch unit may be used 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 realize 3 paths of 4K signals to be simultaneously connected, and at the same time, the first interface, the second interface and the third interface are also started to receive the input signals. In addition, 3 paths of simultaneous video and preview can be supported, and single path 4K fusion smooth optical zooming is also supported.
Referring to fig. 6, a flow chart of an ultra high definition multi-shot input switching method provided by an embodiment of the present application is shown, and an execution subject of the method shown in fig. 6 may be a software and/or hardware device. The execution body of the present application may include, but is not limited to, at least one of: user equipment, network equipment, etc. The user equipment may include, but is not limited to, computers, smart phones, personal digital assistants (Personal Digital Assistant, abbreviated as PDA), and the above-mentioned electronic devices. The network device may include, but is not limited to, a single network server, a server group of multiple network servers, or a cloud of a large number of computers or network servers based on cloud computing, where cloud computing is one of distributed computing, and a super virtual computer consisting of a group of loosely coupled computers. This embodiment is not limited thereto. The method comprises the steps of S101 to S102, and specifically comprises the following steps:
s101, identifying a focal rate value of an input signal.
It can be appreciated that the present solution may first receive an input signal of a lens, for example, an input signal of a short-focus lens, a medium-focus lens or a long-focus lens, and then identify a focal value of the input signal. Wherein the focus value may be varied according to a user's operation of switching zoom using APP on the electronic device.
S102, if the focal value is in the short-focus range, connecting the short-focus lens with a data interface of an ISP unit according to a switch unit;
when the Jiao Lvzhi range enters the middle-focus range from the short-focus range, the middle-focus lens is connected with a data interface of the ISP unit according to the switch unit, and the short-focus lens is disconnected;
when the Jiao Lvzhi range enters the long-focus range from the middle-focus range, the long-focus lens is connected with a data interface of the ISP unit, and the middle-focus lens is disconnected.
It should be noted that, the present solution can automatically complete the switching of the input signal through the identified focal rate value, so as to implement the ultra-high definition multi-shot zooming function.
For example, referring to fig. 1, if the focal value is in the short-focus range, the switch unit may be triggered to switch the short-focus lens on the data interface of the ISP unit, i.e. to switch the short-focus lens on.
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, and the other end of the first switch is communicated with the first interface to connect the short-focus lens with the first interface, and the short-focus lens signal is accessed.
As another example, when the focal value is changed from the short-focus range to the mid-focus range, the mid-focus lens is turned on the data interface of the ISP unit and the short-focus lens is turned off according to the switching unit, i.e., when the user adjusts the anxiety value from the short-focus range to the mid-focus range, it is necessary to switch to the mid-focus lens input signal and to cut off the input of the short-focus lens, at which time the switching can be achieved by the switching unit.
Specifically, this scheme can automatic switch over the state of first switch and second switch for the one end of second switch intercommunication well burnt camera lens, 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 well burnt camera lens with switch-on well burnt camera lens with first interface realizes the switch-in of well burnt camera lens signal, simultaneously because first switch has disconnected the connection with short burnt camera lens, can't receive the input signal of short burnt camera lens this moment, has carried out the disconnection of short burnt camera lens promptly.
In practical application, after the middle-focus lens is connected with 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 middle-focus lens can be further subjected to smooth zooming based on a preset zooming model, and a smooth zooming effect can be achieved in the switching process of the two lenses.
Still another example, when Jiao Lvzhi enters the tele range from the mid range, the tele lens is turned on to the data interface of the ISP unit and the mid lens is turned off, i.e., when the user adjusts the anxiety value from the mid range to the tele range, it is necessary to switch to the tele lens input signal and to cut off the inputs of the mid lens and the short lens.
Specifically, the scheme only needs to automatically connect the long-focus lens to the third interface of the ISP unit, and automatically cuts off the input of the medium-focus lens and the short-focus lens, and only the input of the long-focus lens is performed at the moment. The switching-off mode may be, for example, not to activate the first interface and the second interface, but to activate only the third interface.
Referring to fig. 7, a flowchart of another ultra high definition multi-shot input switching method according to an embodiment of the present application includes steps S201 to S202, which are specifically as follows: comprising 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 medium-focus lens with the data interface of the ISP unit according to a switch unit;
s202, performing fusion zooming processing on the short-focus lens, the medium-focus lens and the long-focus lens.
It can be understood that if the mode is in 4K resolution, the performance of the ISP unit can meet the processing requirement, so that the switch unit can be used to automatically 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 realize 3 paths of 4K signals to be simultaneously connected, and simultaneously, the first interface, the second interface and the third interface are also started to receive the input signals. In addition, 3 paths of simultaneous video and preview can be supported, and single path 4K fusion smooth optical zooming is also 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 resolutions may be applied, which is not described herein.
