According to an aspect of the present application, a camera is provided, and the camera according to an embodiment of the present application will be described below with reference to FIG. 1 .

FIG. 1 shows a schematic block diagram of a camera 100 according to an embodiment of the present application. As shown in FIG. 1 , the camera 100 includes a sensing shutter 110 , and the camera 100 includes a first working mode and a second working mode. When the camera 100 is in the first working mode, the sensing shutter 110 is used to receive a touch sensing input, and the camera 100 Perform different operations based on different contact sensing inputs; when the camera 100 is in the second working mode, the sensing shutter 110 is used to receive contact sensing inputs and non-contact sensing inputs, and the camera 100 is based on different contact sensing inputs and non-contact sensing inputs The sensor input performs different actions.

In the embodiment of the present application, the camera 100 performs operations based on the sensing shutter 110, and the sensing shutter 110 may receive sensing input, including receiving contact sensing input or receiving a combination of contact sensing input and non-contact sensing input, correspondingly, sensing The parameters may include contact sensing parameters, and may also include non-contact sensing parameters. The sensing shutter 110 may be a touch component capable of receiving contact sensing input, such as any one of a capacitive sensing touch key or a resistive sensing touch key; in addition, the sensing shutter 110 may be provided with a sensor that can receive non-contact sensing input, Such as a light sensor, a distance sensor, etc. (will be described in detail later in conjunction with the embodiments). Compared with the traditional mechanical shutter, the inductive shutter 110 receives inductive input, has no mechanical parts, will not wear out, has an infinite life, and can reduce maintenance costs in the later period; and it can be integrated with the fuselage, and there is no water ingress caused by the tiny gaps between the buttons. The problem is that the waterproof and anti-fouling ability is better; and the sensing shutter has no stroke, which can reduce the shutter delay, and it is not easy to be accidentally touched, avoid unnecessary wake-up, and increase the use time of the camera 100. When the camera 100 is in the first working mode , the sensing shutter 110 is used for receiving contact sensing input, and the camera 100 performs different operations based on different contact sensing inputs; when the camera 100 is in the second working mode, the sensing shutter 110 is used for receiving contact sensing input and non-contact sensing input Input, the camera 100 performs different operations based on different contact sensing inputs and non-contact sensing inputs, so that in different working modes, the In combination, the camera 100 can be controlled to perform different operations, so that the camera can be controlled more conveniently and flexibly, the control of the camera is made more intelligent, and the user experience is enhanced.

Whether the camera 100 is in the first operating mode or the second operating mode can be set by the user or there is a default setting but the mode can be changed by the user. The following first describes the operation of the camera 100 when the camera 100 operates in the first operating mode, that is, when the sensing shutter 110 receives a touch sensing input. In the embodiments of the present application, the touch sensing parameters may include at least one of the following: touch area, touch fingerprint, touch strength, and touch time. Exemplarily, the camera 100 may perform different operations mainly based on differences in touch strength and/or touch time, the touch area may be mainly used to determine whether it is a false touch, and the touch fingerprint may be mainly used to ensure the security of the operation of the camera 100 . .

In the embodiment of the present application, the sensing shutter 110 can distinguish different touch strengths on the sensing shutter 110 based on a pressure sensor, can also distinguish different touching times on the sensing shutter 110 based on a timer, or a combination of the two, so as to realize Different actions are performed according to different sensing parameters (touch force and/or touch time).

In this embodiment of the present application, when the touch strength is less than or equal to the first threshold, and/or the touch time is less than or equal to the second threshold, the camera 100 may perform any one of a wake-up operation, a live view operation, and a focus operation. Here, the first threshold is a strength threshold, and the second threshold is a time threshold. In the embodiments of the present application, the specific values of the first threshold and the second threshold may be set according to requirements, may be preset, may be set by the user, or may be modifiable.

In the embodiment of the present application, the operation to be performed by the camera 100 may be determined according to the current state of the camera 100 , that is, which one of the wake-up operation, the live view operation, and the focus operation to perform. For example, when the touch strength is less than or equal to the first threshold, and/or the touch time is less than or equal to the second threshold: if the camera 100 is in a sleep state, a wake-up operation can be performed; if the camera 100 is not in a sleep state and is not in real-time If the camera 100 is in the live view state, the live view operation may be performed; if the camera 100 is in the live view state, the focus operation may be performed.

In this embodiment of the present application, when the touch strength is greater than the third threshold, and/or the touch time is greater than the fourth threshold, the camera 100 may perform an image acquisition operation (ie, a photographing or video recording operation). Here, the third threshold is a strength threshold, and the fourth threshold is a time threshold. In the embodiments of the present application, the specific values of the third threshold and the fourth threshold may be set according to requirements, may be preset, may be set by the user, or may be modifiable. In addition, the third threshold here may be equal to the aforementioned first threshold, or the aforementioned first threshold may be smaller than the third threshold here; similarly, the fourth threshold here is the same as the aforementioned first threshold. Compared with the aforementioned second threshold, the two may be equal, or the aforementioned second threshold may be smaller than the fourth threshold here.

In the embodiment of the present application, the operation to be performed by the camera 100 , that is, how to perform the image acquisition operation, may be determined according to the current state of the camera 100 . For example, if the camera 100 is in a sleep state, the image capture operation can be performed after the wake-up operation, or the image capture operation can be performed after the wake-up operation, live view operation, and focus operation; In the live view operation, the image capture operation can be performed after the live view operation and the focus operation; if the camera 100 is in the live view state but the focus operation has not been performed, the image capture operation can be performed after the focus operation; if the camera 100 has performed the focus operation Focus operation, you can directly perform image acquisition operation.

In other embodiments, when the sensing parameters include both the touch strength and the touch time, a more complex judgment mechanism may be used to perform more precise control over the operation of the camera 100, for example, the touch strength and touch time of the current sensing input may be judged Each has a relationship with a force threshold and a time threshold, and based on different combinations of the relationships, the camera 100 is controlled to perform different operations. For example, when the touch strength is less than or equal to the strength threshold and the touch time is less than or equal to the time threshold, the camera 100 can perform a wake-up operation; when the touch strength is less than or equal to the strength threshold and the touch time is greater than the time threshold, the camera 100 can perform a live view operation; when the touch When the strength is greater than the strength threshold and the touch time is less than or equal to the time threshold, the camera 100 can perform a focus operation; when the touch strength is greater than the strength threshold and the touch time is greater than the time threshold, the camera 100 can perform image capture operations and the like. In this example, due to the complexity of the judgment mechanism, the camera 100 may be controlled to perform corresponding operations only based on the parameter size of the sensing input without taking into account the current state of the camera 100 . Of course, this is only an example. In other embodiments, when the sensing parameters include touch strength and touch time at the same time, the operations performed by the camera 100 according to different sensing parameters may also be in other situations, and may also be combined with the camera 100 The current state further determines the specific operation the camera 100 should perform.

In general, the camera 100 according to the embodiment of the present application can determine the image acquisition-related operations that the camera 100 should perform, such as a wake-up operation and a live view operation, according to the magnitude of the sensing parameter associated with the current sensing input, with or without the current state of the camera 100 . , focusing operations, and image acquisition operations, etc., can achieve automatic, efficient and high-quality image acquisition.

In a further embodiment of the present application, when the sensing shutter 110 receives a touch sensing input, the touch area and/or the touch fingerprint can also be judged. In one example, when the touch area is less than or equal to the fifth threshold, and/or the touch fingerprint is a non-preset fingerprint, the camera 100 does not perform the following operations: wake-up operation, live view operation, focus operation, and image capture operation. In this example, it is possible to avoid responding to an accidental touch, and it is also possible to ensure that the camera 100 is not used by people with non-preset fingerprints, thereby ensuring security. Here, the fifth threshold is an area threshold, and the specific value of the fifth threshold can be set according to requirements, which can be preset, or set by the user, or can be modified.

In some application scenarios, it is necessary to take a quick photo. Since the focus operation needs to be performed before taking a photo, focusing on the touch-sensitive shutter and then taking a photo with the touch-sensitive shutter will result in a certain waiting time for taking a photo, and this kind of waiting Time will affect the timeliness of taking pictures.

In order to further solve the problem of waiting for taking pictures, the camera 100 of the embodiment of the present application can also work in the second working mode, that is, the sensing shutter 110 receives non-contact sensing input and contact sensing input. In one embodiment, when the sensing shutter 110 receives a contactless sensing input, a focusing operation can be performed; and within a predetermined time after the contactless sensing input, when the camera 100 receives the contact sensing input, the camera 100 may perform image acquisition operations. In this embodiment, the operation of the camera 100 can be controlled in combination with the non-contact sensing input and the contact sensing input. When the user needs to take a photo, he only needs to touch the sensing shutter 110 once to complete focusing and taking a photo. Specifically, During the process of touching the sensing shutter 110 , a certain part of the user (eg hand) gradually approaches the sensing shutter 110 and finally contacts the sensing shutter 110 . When a certain part of the user (eg hand) approaches the sensing shutter 110 , the sensing shutter 110 A non-contact sensing input is received, so as to perform a focusing operation. When a certain part of the user (such as a hand) touches the sensing shutter 110, the sensing shutter 110 receives the contact sensing input, thereby performing a photographing operation. The sensor shutter is only touched once, and there is no need to touch the sensor shutter twice to focus and take pictures, so the waiting time for taking pictures is shortened, the pictures can be taken in time, and the user experience is enhanced.

In one example, the non-contact sensing parameter may include a non-contact input time, and when the non-contact input time is greater than or equal to a sixth threshold, the camera 100 may perform a focusing operation. In another example, the non-contact sensing parameter may include a non-contact input distance, and when the non-contact input distance is less than or equal to a seventh threshold, the camera 100 may perform a focusing operation. Here, the sixth threshold is a time threshold, and the seventh threshold is a distance threshold. Here, the specific values of the sixth threshold and the seventh threshold can be set according to requirements, which can be preset, or set by the user, or can be modified.

In one embodiment of the present application, the sensing shutter 110 may be disposed on the body of the camera 100 , for example, on the display screen of the camera 100 or other suitable positions. In another embodiment of the present application, the inductive shutter 110 may be disposed on an accessory outside the camera 100, and the inductive shutter 110 may be connected to and control the camera 100 in a wireless or wired manner. Illustratively, inductive shutter 110 may be a remote accessory to camera 100 . For example, the inductive shutter 110 may be provided on the display screen of the remote controller of the camera 100 or the like.

In a further embodiment of the present application, the camera 100 according to the embodiment of the present application may further include a vibration motor 120. As shown in FIG. 1, when the sensing shutter 110 receives a sensing input, the vibration motor 120 may provide vibration feedback, This not only provides the user with tactile feedback to confirm the sensory input, but also increases the feel of the keys and improves the user experience.

In the embodiment of the present application, the vibration motor 120 may provide vibration feedback when the sensing shutter 110 receives the sensing input (regardless of the size of the sensing parameter), or may only provide vibration feedback under certain circumstances, for example, only when the touch force is greater than The third threshold, and/or, the vibration feedback is provided when the touch time is greater than the fourth threshold, or the vibration feedback is provided under other conditions. In addition, in the embodiment of the present application, whether the vibration motor 120 vibrates and/or the vibration intensity can be set by the user, for example, setting the switch of the vibration motor 120 and/or setting the vibration intensity gear of the vibration motor 120, which It can meet the needs of different users for the vibration of the fuselage.

Based on the above description, the camera according to the embodiment of the present application provides an inductive shutter, so that the camera can perform different operations according to different inductive parameters. Waterproof, dustproof and antifouling, and the sensing shutter has no stroke, which can reduce the shutter delay, and is not easy to be accidentally touched, avoid unnecessary wake-up, and increase the use time. In addition, the camera of the embodiment of the present application includes a first working mode and a second working mode Working mode, wherein, when the camera is in the first working mode, the inductive shutter is used to receive touch-sensing inputs, and the camera performs different operations based on different touch-sensing inputs; when the camera is in the second working mode, the inductive shutter is used to receive Contact sensing input and non-contact sensing input, the camera performs different operations based on different contact sensing input and non-contact sensing input, so that in different working modes, the The combination of input and non-contact sensing input is used to control the camera to perform different operations, so that the camera can be controlled more conveniently and flexibly, making the control of the camera more intelligent and enhancing the user experience.

The following describes a control method for image acquisition provided according to another aspect of the present application with reference to FIGS. 2 to 4 . FIG. 2 shows a schematic flowchart of a method 200 for controlling image acquisition according to an embodiment of the present application. As shown in FIG. 2 , the control method 200 for image acquisition may include the following steps:

In step S210, the current working mode of the camera is determined, and the working mode includes a first working mode and a second working mode. When it is determined that the camera is currently in the first working mode, the control method 200 proceeds to step S220; when it is determined that the camera is currently in the second working mode, the control method 200 proceeds to step S230.

In step S220, it is determined that the camera is in the first working mode, the contact sensing input is received, and the camera is controlled to perform different operations according to different contact sensing inputs.

In step S230, it is determined that the camera is in the second working mode, the contact sensing input and the non-contact sensing input are received, and the camera is controlled to perform different operations according to the different contact sensing input and the non-contact sensing input.

In the embodiments of the present application, the control method 200 for image capture according to the embodiments of the present application may be performed by a camera with a sensor shutter (for example, the camera 100 described above in conjunction with FIG. 1 ), or by a control device of the camera, such as Remote control, mobile terminal, etc. with inductive input function to execute.

Similar to the above, in the embodiment of the present application, according to the working mode (the first working mode or the second working mode) of the camera determined in step S210, different sensing inputs can be received, and the camera can be controlled to perform different operations. The control of image acquisition in these two working modes will be further described below in conjunction with Fig. 3 and Fig. 4, wherein Fig. 3 is the control method of the camera in the first working mode, and Fig. 4 is the control method of the camera under the second working mode Control Method.

FIG. 3 shows a schematic flowchart of a method 300 for controlling image acquisition according to another embodiment of the present application. As shown in FIG. 3 , the control method 300 for image acquisition may include the following steps:

In step S310, a touch sensing input is received, and a touch force and/or a touch time of the touch sensing input is determined. If the touch strength is less than or equal to the first threshold, and/or the touch time is less than or equal to the second threshold, go to step S320; if the touch strength is greater than the third threshold, and/or the touch time is greater than the fourth threshold, go to step S320 S330.

In step S320, the touch strength is less than or equal to the first threshold, and/or the touch time is less than or equal to the second threshold, and the camera is controlled to perform any one of a wake-up operation, a live view operation, and a focus operation.

In step S330, when the touch strength is greater than the third threshold, and/or the touch time is greater than the fourth threshold, the camera is controlled to perform an image capture operation (ie, a photographing or video recording operation).

In the embodiment of the present application, the first threshold and the third threshold are intensity thresholds, and the second threshold and the fourth threshold are time thresholds. The specific values of the first threshold, the second threshold, the third threshold, and the fourth threshold may be set according to requirements, and may be preset, or set by the user, or may be modifiable. In one example, the first threshold is less than or equal to the third threshold, and the second threshold is less than or equal to the fourth threshold.

In a further embodiment of the present application, in step S320, the operation to be controlled by the camera may be determined according to the current state of the camera, that is, which one of the wake-up operation, live view operation and focus operation to control the camera to perform. For example, when the touch strength is less than or equal to the first threshold, and/or the touch time is less than or equal to the second threshold: if the camera is in a sleep state, the camera can be controlled to perform a wake-up operation; if the camera is not in a sleep state and not in real-time If the camera is in the live view state, you can control the camera to perform a live view operation; if the camera is in the live view state, you can control the camera to perform a focus operation.

In a further embodiment of the present application, in step S330, an operation that should be controlled to be performed by the camera may be determined according to the current state of the camera, that is, how to control the camera to perform an image capture operation. For example, when the touch strength is greater than the third threshold and/or the touch time is greater than the fourth threshold, if the camera is in a dormant state, the camera can be controlled to perform a wake-up operation and then perform an image capture operation, or perform a wake-up operation, live view operation and focus operation before performing the image capture operation; if the camera is not in the sleep state but has not yet performed the live view operation, you can control the camera to perform the live view operation and focus operation before performing the image capture operation; if the camera is in the live view state but not yet After the focus operation is performed, the camera can be controlled to perform the focus operation and then the image capture operation can be performed; if the camera has already performed the focus operation, the image capture operation can be directly performed.

In other embodiments, when the sensing parameters include both the touch strength and the touch time, a more complex judgment mechanism can be used to control the operation performed by the camera more accurately, for example, the current sensing input touch strength and touch can be judged. The time is each related to the force threshold and the time threshold, and based on different combinations of the relationship, the camera is controlled to perform different operations. For example, when the touch strength is less than or equal to the strength threshold and the touch time is less than or equal to the time threshold, the camera can be controlled to perform a wake-up operation; when the touch strength is less than or equal to the strength threshold and the touch time is greater than the time threshold, the camera can be controlled to perform a live view operation; When the force is greater than the force threshold and the touch time is less than or equal to the time threshold, the camera can be controlled to perform the focusing operation; when the touch force is greater than the force threshold and the touch time is greater than the time threshold, the camera can be controlled to perform image capture operations, etc. In this example, due to the complexity of the judging mechanism, the camera can be controlled to perform corresponding operations only based on the parameter size of the sensing input without taking into account the current state of the camera. Of course, this is only an example. In other embodiments, when the sensing parameters include touch strength and touch time at the same time, controlling the camera to perform operations according to different sensing parameters may also be in other situations, and may also be combined with the current state of the camera. Further determine what exactly should control the camera to do.

In general, the image capture control method according to the embodiment of the present application can determine the image capture-related operations that the camera should perform, such as wake-up operation, live view, in combination with or not in combination with the current state of the camera, according to the magnitude of the sensing parameter associated with the current sensing input. operation, focusing operation, and image acquisition operation, etc., can realize automatic, efficient and high-quality image acquisition.

In a further embodiment of the present application, when a touch sensing input is received in step S210 or step S310, the touch area and/or touch fingerprint may also be judged. In one example, when the touch area is less than or equal to the fifth threshold, and/or the touch fingerprint is a non-preset fingerprint, the camera is controlled not to perform the following operations: wake-up operation, live view operation, focus operation, and image capture operation. In this example, it is possible to avoid responding to accidental touches, and to ensure that the camera is not used by people with non-preset fingerprints, ensuring security. Here, the fifth threshold is an area threshold, and the specific value of the fifth threshold can be set according to requirements, which can be preset, or set by the user, or can be modified.

As mentioned above, a non-contact sensing input may also be received in step S210 or in step S310. It will be described below with reference to FIG. 4 .

FIG. 4 shows a schematic flowchart of a method 400 for controlling image acquisition according to still another embodiment of the present application. As shown in FIG. 4 , the control method 400 for image acquisition may include the following steps:

In step S410, a contactless sensing input is received, and a contactless input time and/or a contactless input distance of the contactless sensing input is determined. If the non-contact input time is greater than or equal to the sixth threshold, and/or the non-contact input distance is less than or equal to the seventh threshold, step S420 is performed.

In step S420, the non-contact input time is greater than or equal to the sixth threshold, and/or the non-contact input distance is less than or equal to the seventh threshold, and the camera is controlled to perform a focusing operation.

In step S430, within a predetermined time after the non-contact sensing input, the contact sensing input is received, and the camera is controlled to perform an image capture operation.

In this embodiment, the operation of the camera can be controlled in combination with the non-contact sensing input and the contact sensing input. When the user needs to take a photo, he only needs to touch the sensing shutter once to complete focusing and taking a photo. During the process of sensing the shutter, a certain part of the user (such as a hand) gradually approaches the sensing shutter, and finally contacts the sensing shutter.
