[0030] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.
[0031] The various numbers, such as first, second, etc., referred to in the present disclosure are merely used for differentiation for the convenience of description, and are not intended to limit the scope of the embodiments of the present disclosure, nor to represent a sequence.
[0032] Figure 1 is a flowchart of a method for invoking a camera according to an exemplary embodiment. As shown in Figure 1 , the method can include, but is not limited to, the following steps.
[0033] Step S101: Determine that a first screen of a foldable device interacts with a user.
[0034] The first screen can be an inner screen or an outer screen of the foldable device.
[0035] Step S102: In response to a first application invoking a target camera to perform an image acquisition operation on a front scene of the first screen, configure a logical camera.
[0036] When the first screen is an outer screen of the foldable device, the target camera is a first camera associated with the outer screen, and when the first screen is an inner screen of the foldable device, the target camera is a second camera associated with the inner screen.
[0037] It can be understood that the foldable device can include multiple screens, and the outer screen of the foldable device refers to a screen that can interact with the user when the foldable device is in a folded state; the inner screen of the foldable device refers to a screen other than the outer screen among the screens included in the foldable device. For example, the inner screen can be a screen that is partially or entirely hidden when the foldable device is in a folded state.
[0038] It should be noted that in the embodiments of the present disclosure, the first camera associated with the outer screen can be a camera located on the surface of the outer screen when the foldable device is in a folded state; and the second camera associated with the inner screen can be a camera located on the surface of the inner screen.
[0039] In some embodiments, if the foldable device is in a folded state, the first screen can be determined to be an outer screen of the foldable device, or if the foldable device is in an unfolded state, the first screen can be determined to be an inner screen of the foldable device.
[0040] Specifically, in response to a request of the first application for the foldable device camera to perform image acquisition on a front scene of the first screen, a logical camera in the foldable device is configured.
[0041] As an example, taking the first application as an instant messaging application. In response to a user clicking a "video call" function button in the instant messaging application while using the instant messaging application, the instant messaging application calls the camera for video call, and the instant messaging application sends a request for calling the front camera to the foldable device, and at this time, the logical camera corresponding to the foldable device is configured.
[0042] As an example, taking the first application as a camera application. In response to a user clicking an icon of the camera application in the foldable device, if the camera application calls the camera to obtain image data, the camera application sends a request for calling the front camera, and at this time, the logical camera corresponding to the foldable device is configured.
[0043] The first application can be an application installed in the foldable device, or the first application can be an application capable of controlling the foldable device, for example, an application installed on another electronic device capable of controlling the foldable device.
[0044] It should be noted that in the embodiments of the present disclosure, the foldable device is a foldable device capable of folding up and down, that is, the rotation shaft of the foldable device is horizontally arranged.
[0045] Step S103: based on the folding state change of the foldable device, the first camera or the second camera is called through the logical camera.
[0046] Specifically, after obtaining the request of the first application for calling the front camera, the folding state of the foldable device is continuously monitored, so as to obtain the folding state change of the foldable device during the calling of the front camera by the first application, and based on the folding state change of the foldable device at different times, the first camera or the second camera is called through the logical camera, which is suitable for the actual folding state.
[0047] By implementing the embodiments of the present disclosure, when the front camera of the foldable device needs to be called, the logical camera of the foldable device can be set, so as to call the first camera or the second camera through the logical camera based on the folding state change of the foldable device. Based on the folding state change of the foldable device, the camera suitable for the actual folding state can be quickly switched, and the user experience is improved.
[0048] In some embodiments, the identification of the camera in the foldable device can be changed, so as to set the cameras arranged on different sides of the foldable device as a logical camera. As an example, please refer to Figure 2 ,Figure 2 is a flowchart illustrating another method for invoking a camera according to an example embodiment. As shown in Figure 2 the method can include, but is not limited to, the following steps.
[0049] Step S201: Determine that the first screen of the foldable device interacts with the user.
[0050] In embodiments of the present disclosure, step S201 can be implemented in any of the embodiments of the present disclosure respectively, and the present disclosure does not limit this nor repeat it.
[0051] Step S202: In response to the first application calling the target camera to perform an image acquisition operation on the scene in front of the first screen, remap the camera identifiers of the first camera and the second camera to the identifier of the logical camera.
[0052] Specifically, in response to the request of the first application calling the target camera to perform an image acquisition operation on the scene in front of the first screen, remap the camera identifier corresponding to the first camera and the camera identifier corresponding to the second camera to modify the camera identifier corresponding to the first camera and the camera identifier corresponding to the second camera to the identifier of the logical camera.
[0053] Wherein, the identifier of the logical camera can be pre-configured.
[0054] Step S203: Based on the identifier of the logical camera, power on the first camera and the second camera.
[0055] Specifically, based on the logical camera identifier, the logical camera is called to power on the first camera and the second camera at the same time, so as to start the first camera and the second camera at the same time.
[0056] Wherein, the first camera is at least one, and the second camera is at least one.
[0057] It should be noted that the first camera can be multiple, and when the first camera is powered on, each first camera can be powered on, or a pre-determined camera in the first camera can be powered on.
[0058] It should be noted that the second camera can be multiple, and when the second camera is powered on, each second camera can be powered on, or a pre-determined camera in the second camera can be powered on.
[0059] Step S204: Based on the change of the folding state of the foldable device, call the first camera or the second camera through the logical camera.
[0060] In the embodiments of the present disclosure, step S204 can be implemented in any of the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitation thereto, and will not be repeated here.
[0061] By implementing the embodiments of the present disclosure, the first camera identifier of the first camera and the second camera identifier of the second camera can be remapped to the logical camera identifier, and the first camera and the second camera can be started at the same time, so that the corresponding camera is activated based on the folding state of the foldable device and the type of the camera to be called, so that the first application can call the corresponding camera to obtain an image. Based on the change of the folding state of the foldable device, the corresponding camera can be quickly switched to improve the user experience.
[0062] In some embodiments, the corresponding camera can be called through the logical camera according to the folding state of the foldable device at different times. As an example, please refer to Figure 3 , Figure 3 is a flowchart of another method for calling a camera according to an exemplary embodiment. As shown in Figure 3 , the method can include but is not limited to the following steps.
[0063] Step S301: Determine that the first screen of the foldable device interacts with the user.
[0064] In the embodiments of the present disclosure, step S301 can be implemented in any of the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitation thereto, and will not be repeated here.
[0065] Step S302: In response to the first application calling the target camera to perform an image acquisition operation on the scene in front of the first screen, configure the logical camera.
[0066] In the embodiments of the present disclosure, step S302 can be implemented in any of the embodiments of the present disclosure, and the embodiments of the present disclosure do not make any limitation thereto, and will not be repeated here.
[0067] Step S303: Based on the folding state change, it is determined that the folding state of the foldable device has not changed and is in the first folding state.
[0068] Specifically, based on the folding state change of the foldable device, it is determined that during the calling of the front camera by the first application, the folding state of the foldable device remains unchanged in the first folding state.
[0069] In the embodiments of the present disclosure, the above-mentioned first folding state can be a folded state or an unfolded state.
[0070] Step S304: selecting one of the first camera and the second camera as a first target camera based on the first folding state.
[0071] Specifically, based on the first folding state of the foldable device, one of the first camera and the second camera on the same side of the screen currently used by the user is selected as the first target camera.
[0072] In some embodiments, the first folding state is a folded state, and the first target camera is the first camera; or, the first folding state is an unfolded state, and the first target camera is the second camera.
[0073] In the embodiments of the present disclosure, the terms “folded state” and “folding state” can be replaced with each other; the terms “unfolded state” and “unfolding state” can be replaced with each other.
[0074] As an example, in response to the folding state of the foldable device not changing, and the first folding state of the foldable device being a folded state, the first camera is selected as the first target camera.
[0075] As an example, in response to the folding state of the foldable device not changing, and the first folding state of the foldable device being an unfolded state, the second camera is selected as the first target camera.
[0076] Step S305: sending an image acquisition request to the first target camera to activate the first target camera to call the first target camera through the logical camera.
[0077] As an example, taking the first camera as the first target camera, the image acquisition request is sent to the first camera based on the identifier of the logical camera to call the first camera through the logical camera to acquire image data.
[0078] As an example, taking the second camera as the first target camera, the image acquisition request is sent to the second camera based on the identifier of the logical camera to call the first camera through the logical camera to acquire image data.
[0079] By implementing the embodiments of the present disclosure, when the folding state of the foldable device does not change, the first target camera can be selected from the first camera and the second camera based on the first folding state of the foldable device, so as to send the image acquisition request to the first target camera, thereby calling the first target camera to acquire image data. The appropriate camera can be called according to the folding state of the foldable device, thereby improving the user experience.
[0080] In some embodiments, if the folding state of the foldable device changes, the actually called camera can be switched based on the folding state change of the foldable device. As an example, please refer toFigure 4 , Figure 4 is a flowchart of still another method for invoking a camera according to an example embodiment. As shown in FIG. 13, the method can include, but is not limited to, the following steps. Figure 4
[0081] Step S401: Determine that the first screen of the foldable device interacts with the user.
[0082] In embodiments of the present disclosure, step S401 can be implemented in any of the manners described in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be repeated.
[0083] Step S402: In response to the first application invoking the target camera to perform an image acquisition operation on the front scene of the first screen, configure a logical camera.
[0084] In embodiments of the present disclosure, step S402 can be implemented in any of the manners described in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be repeated.
[0085] Step S403: Based on the folding state change, determine that the folding state of the foldable device changes from the first folding state to the second folding state, and select one of the first camera and the second camera as the second target camera.
[0086] In embodiments of the present disclosure, the second target camera in the second folding state is not the same as the first target camera in the first folding state.
[0087] As an example, if the first target camera is the first camera, the second target camera is the second camera.
[0088] As an example, if the first target camera is the second camera, the second target camera is the first camera.
[0089] In embodiments of the present disclosure, the second folding state described above can be a folded state or an unfolded state, and the first folding state and the second folding state are different.
[0090] As an example, if the first folding state is a folded state, the second folding state is an unfolded state.
[0091] As an example, if the first folding state is an unfolded state, the second folding state is a folded state.
[0092] Specifically, based on the folding state change, it is determined that the folding state of the foldable device changes from a first folding state to a second folding state during the first application calling the front camera, and one of the first camera and the second camera that is different from the first target camera is selected as the second target camera.
[0093] In some embodiments, the first folding state is a folded state, and the second folding state is an unfolded state, and the second target camera is the second camera; or, the first folding state is the unfolded state, and the second folding state is the folded state, and the second target camera is the first camera.
[0094] As an example, it is determined that the folding state of the foldable device changes from the folded state to the unfolded state, and the second camera is selected as the second target camera.
[0095] As an example, it is determined that the folding state of the foldable device changes from the unfolded state to the folded state, and the first camera is selected as the second target camera.
[0096] It should be noted that in some embodiments of the present disclosure, corresponding angle ranges can be set for the folded state and the unfolded state of the foldable device. Thus, the folding state of the foldable device can be determined according to the angle range to which the folding angle between the upper and lower parts of the foldable device belongs.
[0097] As an example, the folding angle corresponding to the unfolded state is greater than 30 degrees and less than or equal to 180 degrees, and the folding state is greater than or equal to 0 degrees and less than or equal to 30 degrees. If the folding angle of the foldable device is 180 degrees when the foldable device is in the first folding state, when the user changes the folding angle of the foldable device from 180 degrees to 120 degrees, it is determined that the folding state of the foldable device does not change; when the user changes the folding angle of the foldable device from 180 degrees to 20 degrees, it is determined that the folding state of the foldable device changes from the unfolded state to the folded state.
[0098] In some embodiments, the folding state of the foldable device can be determined to change based on the folding operation or unfolding operation of the user on the foldable device.
[0099] Step S404: sending an image acquisition request to the second target camera and stopping sending an image acquisition request to the first target camera, to activate the second target camera and deactivate the first target camera, to call the second target camera through the logical camera.
[0100] As an example, taking the first target camera as the first camera and the second target camera as the second camera. The image acquisition request is sent to the second camera, and the image acquisition request is stopped to the first camera, to activate the second camera and deactivate the first camera, to call the second camera to acquire image data.
[0101] As an example, taking the first target camera as the second camera and the second target camera as the first camera as an example. An image acquisition request is sent to the first camera, and the sending of the image acquisition request to the second camera is stopped to activate the first camera and deactivate the second camera to call the first camera to acquire image data.
[0102] It can be understood that if the folding state of the foldable device changes again, the first camera and the second camera can be controlled according to the steps provided in any embodiment of the present disclosure based on the folding state before and after the change each time the folding state of the foldable device changes.
[0103] By implementing the embodiments of the present disclosure, the second target camera can be activated and the first target camera can be deactivated when the folding state of the foldable device changes, so as to switch the called camera. Thus, based on the folding state change of the foldable device, the camera suitable for the actual folding state can be quickly switched to, and the user experience is improved.
[0104] In some embodiments of the present disclosure, the above method further comprises: determining that the first application stops calling the front camera, and powering down the first camera and the second camera.
[0105] In some embodiments of the present disclosure, before the step of configuring the logical camera, the above method further comprises: obtaining the current folding state of the foldable device; and determining that the current folding state is the folded state, and continuing to execute the step of calling the logical camera of the foldable device.
[0106] Specifically, in the case that the folding state of the foldable device is the folded state when it is determined that the first application calls the front camera, the logical camera of the foldable device and the subsequent steps in the foregoing embodiments of the present disclosure are continued to be executed.
[0107] In some embodiments of the present disclosure, the above method can further comprise: obtaining the current folding state of the foldable device; and determining that the current folding state is the unfolded state, and powering up the second camera to enable the first application to call the second camera.
[0108] Specifically, when it is determined that the first application calls the front camera, the current folding state of the foldable device is the unfolded state, and the second camera is powered up, so that the first application can call the second camera to acquire image data.
[0109] Optionally, the above method further comprises: in response to the folding state of the foldable device changing from the unfolded state to the folded state, powering up the first camera and powering down the second camera, so as to call the first camera to acquire image data.
[0110] It can be understood that if the folding state of the foldable device changes again, the power-on and power-off states of the first camera or the second camera can be adjusted again based on the folding state of the foldable device after the change each time the folding state of the foldable device changes.
[0111] Referring to Figure 5 , Figure 5 is a schematic diagram of a camera calling scheme according to an exemplary embodiment. As shown in Figure 5 , when a user needs to call a front camera (i.e., logical camera 1 shown in Figure 5 ) through an application, if the foldable device is currently in a folded state, the camera ID of the first camera (i.e., physical camera 0 shown in Figure 5 ) disposed on one side of the outer screen of the foldable device and the camera ID of the second camera (i.e., physical camera 1 shown in Figure 5 ) on one side of the inner screen are remapped to the corresponding camera ID of a virtual camera (i.e., logical camera 8 shown in Figure 5 ), and the camera is powered on; the logical camera is called through the configure_streams 8 instruction; the image data acquisition request is sent to the first camera to acquire image data using the first camera; when the folding state of the foldable device changes, if the changed folding state is an unfolded state, the image data acquisition request is sent to the second camera to acquire image data using the second camera; if the changed folding state is a folded state, the image data acquisition request is sent to the first camera to acquire image data using the first camera; after the user stops calling the front camera through the first application, the first camera and the second camera are powered off (i.e., Release physical camera 0 and Release physical camera 1 shown in Figure 5 ).
[0112] If the foldable device is currently in an unfolded state, the second camera is directly powered on through configure_streams to acquire image data using the second camera; when the folding state of the foldable device changes, the powered-on camera is powered off and the powered-off camera is powered on, thereby realizing switching of the front camera; after the user stops calling the front camera through the first application, the powered-on camera is powered off.
[0113] Referring to Figure 6 , Figure 6 is a schematic diagram of a camera calling device according to an exemplary embodiment. As shown inFigure 6 As shown, the apparatus 600 includes: a first processing module 601 configured to determine that a first screen of a foldable device interacts with a user; a second processing module 602 configured to, in response to a first application calling a target camera, configure a logical camera to perform an image capturing operation on a front scene of the first screen; and a third processing module 603 configured to, based on a folding state change of the foldable device, call a first camera or a second camera through the logical camera.
[0114] In an implementation manner, the second processing module 602 is specifically configured to: remap camera identifiers of the first camera and the second camera to an identifier of the logical camera; and based on the identifier of the logical camera, power on the first camera and the second camera.
[0115] In an implementation manner, the third processing module 603 is specifically configured to: based on the folding state change, determine that a folding state of the foldable device does not change and is a first folding state; based on the first folding state, select one of the first camera and the second camera as a first target camera; and send an image acquisition request to the first target camera to activate the first target camera, so as to call the first target camera through the logical camera.
[0116] In an optional implementation manner, the first folding state is a folded state, and the first target camera is the first camera; or, the first folding state is an unfolded state, and the first target camera is the second camera.
