Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to illustrate the technical scheme of the application, the following description is made by specific examples.

In order to meet the diversified shooting requirements of users, single-lens reflex cameras or micro-single-lens cameras which are popular in the market can be connected with lenses with different apertures and focal lengths in an external mode. The joint of the camera and the lens is provided with a bayonet, and the lens and the camera can communicate through contacts on the bayonet. The bayonet structures of different models of cameras may also be different, and therefore, it is difficult for the same camera to match different lenses. In addition, because the camera manufacturer keeps secret of the communication protocol between the camera body and the lens, the camera body of the same camera is difficult to adapt to the communication requirements of the lenses of different manufacturers.

In order to solve the above-mentioned problems, an embodiment of the present application provides a device for matching a camera with a lens, i.e. an adapter ring. Fig. 1 is a schematic structural diagram of a camera according to an embodiment of the present application. As shown in fig. 1, the camera includes a lens, an adapter ring, and a body. The lens may comprise lenses of different bayonet types on the market. Lenses of different bayonet structures on the market, including bayonets of different mechanical structures, and/or bayonets defined by different contacts. For example, bayonets of different mechanical configurations may include an EF bayonet, an RF bayonet, an EF-M bayonet, an F bayonet, a Z bayonet, an A bayonet, an FE bayonet, a K bayonet, an X bayonet, an M bayonet, an L bayonet, an S bayonet, an R bayonet, and the like. The differences in the definition of the contact points in the mount of the lens may include an autofocus control contact point, an aperture control contact point, a focus adjustment contact point, a quick control contact point, and the like.

In the embodiment of the application, for the lenses with different mechanisms and the lenses with different contact definitions, the adapter ring matched with the structure and the contact definition of the lenses can be configured. The adapter ring comprises two bayonets, namely a first bayonet and a second bayonet, wherein the mechanical structure of the first bayonet is matched with the mechanical structure of the lens bayonet, and the contact definition of the first bayonet is matched with the contact definition of the lens bayonet. The mechanical structure of the second bayonet of the adapter ring is matched with the mechanical structure of the bayonet of the body, and the contact definition of the second bayonet is matched with the contact definition of the bayonet of the camera. The camera body and the adapter ring can be adapted by adopting a fixed mechanical structure, and can be adapted by adopting a fixed contact definition. Through the adaptation of the mechanical structure, the lens can be arranged on the camera body through the adapter ring; through the adaptation of the contact definition, the data of the lens can be transmitted to the body through the transfer ring, and the control instruction of the body can be transmitted to the lens through the transfer ring. Only the adapter ring which is matched with the lens and has lower cost is needed, so that the camera body can effectively support the functions possessed by the lens.

The adapter ring can acquire the identification information of the lens from the lens through the adaptive contact definition or the adaptive contact position adaptation, and identify the lenses of different models. And storing the corresponding relation between the identification information and the lens parameters at the transfer ring, and searching the lens parameters corresponding to the lens according to the acquired identification information. The searched lens parameters are sent to the machine body, so that the machine body can conveniently perform relevant control or calculation of image acquisition according to the lens parameters, and the image acquisition quality is improved. And the camera body can adapt to lenses with different specifications through the adapter ring, so that the realization of advanced functions possessed by the lenses is supported, and the market competitiveness of the camera is improved.

Fig. 2 is a schematic implementation flow chart of an image acquisition method of a camera according to an embodiment of the present application. The method may be implemented based on the camera shown in fig. 1. The method comprises the following steps:

in S201, according to the contact signal acquired from the lens by the adapter ring, the adapter ring acquires the identification information of the lens.

Specifically, after the first bayonet of the adapter ring is connected with the bayonet of the lens, the contact of the lens is communicated with the contact of the adapter ring, and the identification information of the lenses with different specifications can be determined according to the difference of contact signals transmitted by the lens.

In a possible implementation manner, when the mechanical structure of the first bayonet of the adapter ring is only adapted to the lenses of the same specification and model, the lens parameters corresponding to the lenses connected to the adapter ring can be directly determined when the contact point of the adapter ring receives the contact point signal.

When the first bayonet of the adapter ring can be adapted to two or more lenses with different specifications, identification information corresponding to different lenses can be determined according to the difference of contact signals received by the adapter ring when the lenses with different specifications are connected with the adapter ring. For example, the difference of contact signals of the adapter ring when different lenses are connected can be determined in a pre-calibration mode, and identification information corresponding to the different lenses is determined according to the signals of the contacts. Based on the determined identification information, the specification and model of the connected lens in the plurality of lenses which can be connected with the adapter ring can be uniquely determined.

The lens adapted by the same adapter ring comprises the mechanical structure adaptation of the bayonet and the contact position and the contact definition adaptation of the bayonet. Other lenses which are not matched with the mechanical structure of the first bayonet of the adapter ring cannot be installed with the adapter ring, or other lenses which are not matched with the contact position cannot obtain the contact signal, so that the corresponding relation between the identification information stored in the adapter ring and the lens parameters can only comprise the corresponding relation between the lenses which are matched with the mechanical structure of the adapter ring and the contact position. The correspondence of other unadapted lenses may not need to be stored in the adapter ring.

Because the communication protocols adopted by different lenses may be different, in a possible implementation manner, under the condition that the mechanical structure of the bayonet, the definition of the contact and the contact position are the same, if the adaptive lens comprises more than two lenses and the communication protocols of the lenses are different, the identification information of the lenses with different communication protocols can be determined at the transfer ring in a calibrated mode. According to the determined identification information, a control instruction corresponding to a protocol is conveniently generated in the subsequent lens control operation process, and accurate control of the lens is effectively realized.

In a possible implementation, a protocol corresponding to a plurality of lenses that the adapter ring can adapt to may be stored at the adapter ring. The switching ring may sequentially select one of the plurality of protocols (e.g., the first protocol) from the plurality of protocols to parse the data of the contact signal. And determining the identification information of the lens according to the analyzed signals.

In S202, according to the corresponding relationship between the preset identification information and the lens parameters, the adapter ring searches the lens parameters corresponding to the identification information of the lens.

The corresponding relation between the identification information and the lens parameters is stored at the transfer ring. The lenses with different specifications correspond to different identification information. The lenses with different specifications and models comprise lenses with different communication protocols, or comprise lenses with the same contact positions but different contact definitions, or comprise lenses with different control instructions, and the like.

Because the lens is updated continuously according to the market demand, the correspondence between the identification information stored in the adapter ring and the lens parameters also needs to be updated continuously to adapt to the adaptation requirement of the updated lens.

When the mechanical structure of the updated lens is matched with the adapter ring, the position of the contact point of the updated lens is matched with the first bayonet of the adapter ring, and the definition of the contact point of the bayonet of the updated lens is not matched with the definition of the contact point of the bayonet of the adapter ring, the corresponding relation between the identification information in the adapter ring and the lens parameters can be updated, the lens parameters corresponding to the identification information of the lens are increased, and the corresponding relation comprises the definition of the contact point of the lens. According to the contact definition of the lens mount, a control instruction matched with the contact definition is sent to the phase.

When the mechanical structure of the updated lens is matched with the adapter ring, the position of the contact point of the updated lens is matched with the first bayonet of the adapter ring, and the definition of the contact point of the bayonet of the updated lens is matched with the definition of the contact point of the bayonet of the adapter ring, the corresponding feed of the identification information of the lens and the lens parameters is only needed to be added at the adapter ring.

When the corresponding relation of the transfer ring is updated, the update data can be transmitted to the transfer ring through a communication interface arranged at the transfer ring. The communication interface may comprise a limited communication interface or an unlimited communication interface. The limited communication interface includes, for example, a USB interface. The wireless communication interface may include a bluetooth communication interface, an infrared communication interface, and the like. In a possible implementation, the data that need to be updated in the adapter ring can also be transmitted to the adapter ring through the contacts of the camera body.

The lens parameters in the embodiment of the present application may include image calculation parameters and/or lens control parameters. The image calculation parameters may include at least one of distortion parameters, chromatic aberration parameters, respiratory compensation parameters, and anti-shake parameters for compensating the image. The lens control parameters may include at least one of parameters for controlling the aperture and the focal length of the lens.

In S203, the adapter ring sends the searched lens parameters to the camera body, and the camera body performs image acquisition according to the lens parameters.

After the body receives the lens parameters transmitted by the adapter ring, the image acquired according to the lens parameters can be adjusted according to the lens parameters, including modes of compensation calculation and the like. The compensation calculations may include distortion compensation, color difference compensation, respiratory compensation, anti-shake compensation, and the like.

In a possible implementation, when the lens is a wide-angle lens, the lens parameters may include distortion parameters of the wide-angle lens, including, for example, optical distortion values. After the optical distortion value is obtained by the machine body, the position of the pixel generating distortion is adjusted according to the distortion influence of the optical distortion value on the pixel point in the image, so that the acquired image is subjected to distortion compensation, and the imaging effect of the image is improved.

In a possible implementation, when a pose sensor such as a gyroscope is arranged in the lens, lens shake data of the camera during shooting can be detected. The lens shake data is transmitted to the body of the camera as an anti-shake parameter. The camera body may calculate an instruction to generate compensation lens shake based on the lens shake data. For example, the instruction can be transmitted to the magnetic coil or magnet integrated structure of the lens, so that the optical system of the lens can perform anti-shake compensation.

In a possible implementation, when a pose sensor such as a gyroscope is provided in the lens, shake of the lens due to respiration of the user may be detected. The shake may be transmitted to the body of the camera as a breathing compensation parameter. According to the breathing compensation parameter, the camera body can send out a corresponding control instruction to the lens through a magnetic coil or magnetite integrated structure of the lens or through the change of the focal length so as to realize the breathing compensation of the lens.

In a possible implementation, the acquired image is affected by the lens information in the lens. The collected image can be subjected to color difference compensation according to the lens information included in the lens, and the color and the brightness of the image are adjusted, so that the color of the image is more accurate and natural.

In the embodiment of the application, when the body compensates the lens, a corresponding compensation instruction or adjustment instruction can be generated to control or adjust the lens. For example, the size of the aperture of the lens can be controlled, the size of the aperture of the lens can be adjusted, the size of the focal length of the lens can be controlled, the focal length of the lens can be adjusted, or the automatic focusing of the lens can be realized.

The adjustment instruction generated by the machine body can be transmitted through a fixed second protocol between the machine body and the switching ring, and the adjustment instruction is sent to the switching ring. The adapter ring can send an adjustment instruction to the lens according to a first protocol corresponding to the predetermined lens, so that the lens executes corresponding state adjustment.

Wherein the first protocol may be determined from the received identification information according to the transit ring. Or, the first protocol may also analyze and judge the data of the lens according to a plurality of protocols pre-stored in the adapter ring, so as to determine the first protocol corresponding to the lens.

In a possible implementation manner, the embodiment of the application further provides an image acquisition method based on the switching ring and based on the switching ring, as shown in fig. 3, the method includes:

in S301, according to the contact signal acquired from the lens by the adapter ring, the identification information of the lens is acquired.

In S302, according to the corresponding relationship between the preset identification information and the lens parameters, the lens parameters corresponding to the identification information of the lens are searched.

In S303, the searched lens parameters are sent to the camera body, where the lens parameters are used for image acquisition by the camera body according to the lens parameters.
