Detailed Description
So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
The embodiment provides an image acquisition method; the method is applied to electronic equipment, wherein the electronic equipment can be a mobile phone, a tablet personal computer and the like; here, in this embodiment, the electronic device is capable of performing data communication with the filter device, such as controlling the filter device in a wired or wireless manner; here, the electronic device may send a control instruction to the filter device in a software control manner; further, in practical applications, the filter device may be integrated in the electronic device, or the filter device and the electronic device are independent devices. Specifically, fig. 1 is a schematic flow chart illustrating an implementation of the image acquisition method according to the embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: obtaining a first operation for an electronic device; the first operation is a selection operation of selecting a target filter lens in a filter device which can be controlled by the electronic equipment; the electronic equipment and the filter device have a preset position relation, so that any one of at least one filter lens arranged in the filter device can correspond to an image acquisition assembly arranged in the electronic equipment through movement under the preset position relation;
here, the electronic device may be provided with a main interface and may be capable of connecting with the auxiliary interface of the filter device through the main interface to communicate; furthermore, the electronic device further has a main fixing device, and can be fixedly connected with an auxiliary fixing device on the filter device through the main fixing device, so as to ensure the relative stability of the electronic device and the filter device, and the stable state is that the electronic device and the filter device are in a preset position relationship, the main fixing device and the auxiliary fixing device can be adsorbed together, so that the electronic device and the filter device are fixed together through the adsorption force, the adsorbed electronic device and the filter device are in the preset position relationship, and further, in the preset position relationship, the acquisition channel of the image acquisition assembly of the electronic device can be completely shielded by a specific filter lens in the filter device, so that the acquisition channel of the image acquisition assembly is completely transparent to the specific filter lens for image acquisition, here, the specific filter lens may be any one of the filter lenses in the filter device.
In a specific embodiment, the electronic device presents at least one filter identifier on a display screen, and correspondingly, the obtaining a first operation for the electronic device may specifically include: and acquiring a first operation aiming at a target filter identifier in the at least one filter identifier. Here, each filter identification corresponds to one filter lens, so as to select a target filter lens from at least one filter lens based on the filter identification; the target filter identification is an identification corresponding to the target filter lens. In practical application, as shown in fig. 2, it is assumed that five filter lenses are arranged in the filter device, at this time, five filter identifiers presented in the electronic device respectively correspond to the filter lenses 1 to 5, so that a user can select a target filter lens through the five filter identifiers presented in the electronic device. Here, in practical applications, the filter identifier may be specifically a graphic with a shape similar to that of the filter lens, and of course, the filter identifier may also include characters, such as a name of the filter lens.
Specifically, the filter lens in this embodiment may be: polarizers, starlight mirrors, medium density filters, etc.; the use of the polarizer can remove stray light, such as specular reflection light, reflection light of a metal surface, refraction light in air, and the like, among others. The use of the starlight mirror can create various lighting effects, such as a cross mirror, a Mi-character mirror, and the like. The use of the medium density filter can reduce the amount of light entering, thereby increasing the exposure time and creating some motion effects, such as waterfall movement, cloud movement, and the like.
Step 102: generating a control instruction based on the first operation, and sending the control instruction to the filter device, wherein the control instruction is used for controlling a target filter lens in the filter device to move to a position corresponding to an image acquisition assembly of the electronic equipment, so that the image acquisition assembly acquires images through the target filter lens.
Correspondingly, the filter device receives a control instruction aiming at a target filter lens sent by electronic equipment; the filter device and the electronic equipment have a preset position relation, so that any one of at least one filter lens arranged on the filter device can correspond to an image acquisition assembly arranged in the electronic equipment through movement under the preset position relation; further, the filter device selects the target filter lens from the at least one filter lens based on the control instruction, and controls the target filter lens to move to a position corresponding to an image acquisition component of the electronic device, for example, controls the target filter lens to move to a position capable of completely shielding an acquisition channel of the image acquisition component, so that when the electronic device controls the image acquisition component to acquire an image, the acquisition channel of the image acquisition component can be completely transparent and then the target filter lens is acquired, so that the image acquired by the electronic device achieves an effect similar to that of an image acquired after a filter is arranged in front of a single lens reflex camera lens.
In a specific embodiment, the electronic device detects a first result indicating that the electronic device is connected with the filter device, and sends the control instruction to the filter device; or detecting a second result representing that the electronic equipment is not connected with the filter device, and adjusting and starting a filter algorithm module corresponding to the target filter based on the control instruction so as to respond to the control instruction through the filter algorithm module. Here, the electronic device has a main interface and can be connected to an auxiliary interface of the filter device through the main interface in a communication manner, and correspondingly, the first result indicates that the main interface and the auxiliary interface are in a communication connection state, and the second result indicates that the main interface and the auxiliary interface are not in a communication connection state, that is, a disconnection state.
That is to say, when detecting that the electronic device is connected to the filter device, the electronic device directly sends the control command to the filter device through the communication connection link; otherwise, when detecting that the filter device and the electronic device are not connected, starting a filter algorithm module based on a control instruction, wherein the filter algorithm module is set by the electronic device (here, the filter algorithm module can correspond to an application program capable of processing collected images and realizing a filter effect).
Certainly, in order to obtain a better filter effect, in another embodiment of the present application, the control instruction may be further responded based on the filter device and the filter algorithm module together, for example, the target filter lens is firstly shielded on an acquisition channel of the image acquisition assembly, so that light entering the image acquisition assembly from the outside passes through the target filter lens for imaging, the obtained image after the initial filter processing is performed, and then the filter algorithm module is used to perform image processing (such as filter processing) on the image after the initial filter processing again, so as to obtain a better image effect.
In practical application, after the electronic device sends the control instruction to the filter device, whether the relative position relationship between the image acquisition assembly and the target filter lens meets a preset rule or not can be detected, and whether the image acquisition assembly can be controlled to acquire an image through the target filter lens based on the image acquisition instruction or not is determined according to a detection result; for example, whether the target filter lens can completely block the acquisition channel of the image acquisition assembly is detected, here, when the acquisition channel of the image acquisition assembly can be completely blocked and all light entering the image acquisition assembly is light processed by the target filter lens, it is considered that the relative position relationship between the image acquisition assembly and the target filter lens meets the preset rule, otherwise, it is considered that the relative position relationship between the image acquisition assembly and the target filter lens does not meet the preset rule. Further, when the relative position relation between the image acquisition assembly and the target filter lens meets a preset rule and an image acquisition instruction is detected, controlling the image acquisition assembly to acquire an image through the target filter lens; and when the relative position relation between the image acquisition assembly and the target filter lens does not meet the preset rule, even if an image acquisition instruction is obtained, the image acquisition instruction is not responded, so that the image which does not meet the filter effect is prevented from being acquired because the target filter lens does not move in place. Further, the electronic device may further generate a prompt message to prompt the user that the relative position relationship between the image capture assembly and the target filter lens does not satisfy a preset rule, and ask the user to wait. Here, the image capturing instruction is an image capturing instruction generated by triggering a photographing key (a physical key or a virtual key) on an electronic device (e.g., a mobile phone).
In this way, according to the method provided by the embodiment of the invention, the electronic device is used for controlling the filter device provided with at least one filter lens, and the target filter lens is selected from at least one filter lens in the filter device, so that the image acquisition assembly of the electronic device can acquire images through the target filter lens, and thus, the problems that compared with a professional single lens reflex camera, the existing electronic device is low in imaging quality and cannot achieve the acquisition effect required by a user are solved; moreover, the embodiment of the invention is an automatic process, and does not need a user to manually adjust the required hardware filter, so that the selection time for selecting the filter can be shortened, a foundation is laid for avoiding the user missing the wonderful moment of image acquisition, the user experience is enriched, and the user experience is improved.
In this embodiment, the filter device is a structure capable of controlling the filter lens installed on the filter device to move in an automatic control manner. The following provides a specific structure of the filter device in this embodiment, and a specific description of a control manner of the electronic device for controlling the filter device based on the specific structure of the filter device; in particular, the amount of the solvent to be used,
as shown in fig. 3 to 5, a first hole is formed in the filter device; the first hole corresponds to an image acquisition assembly of the electronic device. In other words, after the filter device is connected to the electronic device, the first cavity of the filter device is located on the external light collecting channel of the image collecting assembly of the electronic device. Each filter lens in the filter device can move and can move to the first hole, and when the filter lens moves to the first hole, the whole area of the first hole is shielded, namely, the filter lens shields a collecting channel (such as a lens) of the image collecting assembly. In this way, it is convenient for the lens of the image capturing component in the electronic device to capture through the first hole (i.e., the filter-free lens), and for the lens of the image capturing component in the electronic device to capture an image by moving to the filter lens of the first hole; that is, the electronic device and the filter device have a preset position relationship that: the image acquisition assembly in the electronic equipment corresponds to the first hole, so that the image acquisition assembly acquires images through the first hole, namely, after the filter device is connected with the electronic equipment, the first hole of the filter device is positioned on an acquisition channel of external light of the image acquisition assembly. In an embodiment of the application, the first hole of the filter device and the image acquisition device of the electronic device are calibrated before leaving the factory, so that the electronic device obtains connection information representing that the filter device is successfully connected with the electronic device, and the electronic device and the filter device meet the preset position relationship. Of course, in other embodiments, it may also be possible to capture the picture in real time, specifically by the image capture assembly, and perform the calibration with the previous one to determine whether the first hole of the filter device is in the capture channel of the ambient light located in the image capture assembly.
For example, when a camera application at an electronic device end (a mobile phone end) is in an operating state, an image acquisition component of the electronic device is in a preview mode, an image acquired by the image acquisition component of the electronic device in the preview mode in real time is displayed through a display screen of the electronic device, if a user needs a filter effect, a plurality of different filter identifiers are displayed on the display screen through triggering operation, and further, if the electronic device obtains connection information representing that a filter device is successfully connected with the electronic device, the electronic device and the filter device meet the preset position relationship (that is, a first hole is located in a path of external light of the image acquisition component), the filter lens can be used for image acquisition; here, the plurality of different filter identifiers correspond to a plurality of different filter lenses on the filter device in a one-to-one manner, or a first filter identifier corresponding to the plurality of different filter lenses on the filter device among the plurality of different filter identifiers has a different display effect on the display screen from other filter identifiers, for example, a highlight or the like, that is, the filter identifiers displayed on the electronic device do not correspond to only the same filter device, and when corresponding to the plurality of filter devices, the identification characteristics (e.g., color, shape, etc.) of the filter identifiers of the filter lenses of the different filter devices on the display screen may be different.
Or, when the mobile phone terminal photographing application is in an operating state, the image acquisition assembly of the electronic equipment is in a preview mode, the display screen of the electronic equipment displays an image acquired by the image acquisition assembly of the electronic equipment in real time in the preview mode, and if the electronic equipment obtains connection information representing successful connection between the filter device and the electronic equipment, the electronic equipment and the filter device meet the preset position relationship (namely, the first hole is located on a path of external light of the image acquisition assembly), a plurality of filter identifications corresponding to a plurality of different filter lenses on the filter device one by one are directly displayed on the display screen for a user to select.
The user determines a target filter lens through selection operation aiming at different filter identifiers, after the selection operation is successful, the mobile phone sends a corresponding control instruction to the filter device, and an automatic device of the filter device controls the target filter lens to automatically move to the first hole based on the control instruction. In the process of controlling the target filter lens to automatically move to the first hole, whether the relative position relation between the image acquisition assembly and the target filter lens meets a preset rule or not can be detected, specifically, whether the target filter lens moves in place or not is detected, namely, whether the target filter lens completely moves to the first hole or not is detected. When the target filter lens moves completely into the first hole, in-place information is generated so as to indicate that the electronic equipment (namely, the mobile phone end) can respond to a photographing instruction.
Further, in a specific embodiment, a rotatable ring structure is provided in the filter device, that is, the rotatable ring structure is an automatic device in the filter device, for example, the automatic device may be a gear capable of automatically rotating, and the movement of the filter lens is controlled by the rotation of the gear; all the filter lenses in the filter device are arranged on the rotatable annular structure so as to be moved to the first holes through the rotation of the rotatable annular structure; as shown in fig. 3, the filter lenses 1 to 5 are all disposed on a rotatable ring structure (e.g., a gear), so that, after a user performs a click operation on a specific filter mark on the display screen, a specific filter lens of the filter lenses 1 to 5 can be rotated to a first hole by the rotatable ring structure; in a corresponding manner, the first and second electrodes are,
the control instruction is specifically configured to control the rotatable ring structure to rotate at least a preset angle, so that a first filter lens of the at least one filter lens or the target filter lens moves to a position corresponding to an image capture component of the electronic device. Here, the rotatable ring structure may rotate several preset angles at a time, for example, the preset angle is a, where the preset angle a is an angle formed by taking a circle center O of the rotatable ring structure as a vertex and taking a line segment formed by the circle center O to the first hole and the filter lens 1 (or the filter lens 5) adjacent to the first hole as an edge; here, in practical application, the angle formed by the origin O and the two adjacent filter lenses can be a, so that when the rotating angle a of the rotatable ring structure is equal to the rotating angle a, the specific filter lens can be ensured to be located in the first hole, and the image acquisition assembly can acquire images through the specific filter lens. For example, after a user selects a target filter lens through a filter identifier on a display screen, the rotatable ring structure can control the target filter lens to move to the first hole by rotating a plurality of preset angles; for another example, each time a user clicks a specific key (physical key or virtual key) on the display screen, the rotatable ring structure rotates by a predetermined angle a, and the process is repeated, so that the user can select a target filter lens after one or more clicks, wherein the filter identifier of the selected target filter lens is different from the filter identifiers of other unselected filter lenses. Of course, the above is only used for explaining the embodiment of the present invention, and is not used for limiting the embodiment of the present invention, in practical applications, the above-mentioned angles may be different as long as the electronic device can control the target filter lens to move to the first hole according to the actual angle.
In another specific embodiment, the electronic device obtains a relative positional relationship between the image capturing assembly and each of the at least one filter lens element in the preset positional relationship, and generates a mapping table representing the relative positional relationship between the image capturing assembly and each of the at least one filter lens element; that is to say, the electronic device records the relative position relationship between each filter lens and the image capturing component in the filter device in a mapping table manner, for example, when the image capturing component in the electronic device corresponds to the first hole and enables the image capturing component to capture an image through the first hole, the electronic device records the relative position relationship between each filter lens and the first hole in the preset position relationship in a mapping table manner. Further, after the user selects the target filter lens, the electronic device selects a first relative position relationship between the image acquisition component and the target filter lens selected by the first operation from the mapping table, determines a movement parameter of the target filter lens according to the first relative position relationship, and generates a control instruction based on the movement parameter, so that the filter device controls the target filter lens to move to a position corresponding to the image acquisition component of the electronic device according to the movement parameter.
Further, in order to enable the electronic device to accurately determine the movement parameter, the electronic device may further detect whether a relative positional relationship between the image capturing assembly and each of the filter lenses changes in the preset positional relationship, and modify the mapping table based on the changed relative positional relationship between the image capturing assembly and each of the filter lenses when the change is determined.
Here, in practical applications, a detection process of a relative positional relationship between the image capturing assembly and each of the at least one filter lens, and/or a detection process of whether a relative positional relationship between the image capturing assembly and each of the at least one filter lens changes may be detected by the electronic device itself, or may be detected by the filter device and then sent to the electronic device.
Fig. 4 and 5 are schematic diagrams illustrating different arrangement manners of filter lenses in the filter device, as shown in fig. 4, the filter device can move the filter lenses to the first holes through the arranged tracks, and different filter lenses can be arranged in different tracks; or, the filter lens centers on first hole sets up, and each filter device can remove the filter lens to first hole through the track that self corresponds, if, five different filter lenses correspond different tracks, like this, electronic equipment only needs to know which track corresponds which filter lens can determine the removal parameter.
The following examples of the present invention are described in further detail with reference to specific applications; specifically, a set of hardware filters is mounted in a seal body, and the seal body is mounted to the back of the handset, for example, by magnetic attraction or by embedding the handset in a housing provided by the seal body (e.g., a handset back case type product). Here, the sealing body may be a battery itself, or may be powered by the electric power of the mobile phone through a contact with the mobile phone. Furthermore, a hole is formed in the sealing body, and the position of the hole is just matched with the position of a camera of the mobile phone. Inside the seal, under mechanical device's drive, can remove the position of specific hardware filter to the hole to shelter from in the front of the camera of cell-phone, reach the purpose of filtering light. For example, a ring-shaped structure may be adopted, a group of filters is mounted on a disk, and the disk is rotated by a servo motor, so that the purpose of rotating the disk to a specified position is achieved.
Here, the sealing body can perform data communication with the mobile phone, for example, data transmission with the mobile phone through a wireless communication mode (bluetooth, near field communication technology NFC or wireless fidelity Wi-Fi, etc.); or, data transmission is carried out with the mobile phone in a wired mode, such as through an electric shock connected with the mobile phone; therefore, under the control of the user, the camera software of the mobile phone can send a control instruction to the sealing body according to the filter type selected by the user, for example, the rotation angle of the servo motor is controlled by the control instruction, so that the purpose that the user controls the automatic movement of the hardware filter through the operation on the user interaction interface is achieved.
Therefore, according to the method provided by the embodiment of the invention, the user can select the specific filter without adjusting the required hardware filter in a manual mechanical mode, the operation process of the user is simplified, the selection speed of selecting a new filter by the user is increased, and the problem that the wonderful moment is missed is effectively avoided. Furthermore, the embodiment of the invention can be realized on the basis of software, so that the full-automatic selection process is realized, and the user experience is further improved. In addition, the attention of the user is still completely focused on the viewing interface of the mobile phone display screen, the filter accessory at the back of the mobile phone does not need to be adjusted by taking care, and a foundation is further laid for improving the image effect.
