Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic diagram of an application scenario of a resolution determination method in a video call process according to an embodiment of the present invention. The method for determining the resolution in the video call process provided by the embodiment of the invention can be executed by the wearable device 12. As shown in fig. 1, the video call in the embodiment of the present invention may occur between the wearable device 12 and the wearable device 13, between the wearable device 12 and the mobile phone 14, or between the wearable device 12 and a Personal Computer (PC) 15. That is, the video call in the embodiment of the present invention may occur between the wearable device 12 and any other device capable of video call. In the embodiment of the invention, when the wearable device 12 performs the video call, the resolution of the image can be intelligently reduced according to the image acquired by the camera, so that the data volume uploaded in the video call process is reduced, the power consumption of the wearable device is reduced, and the user experience is further improved.
Fig. 2 is a flowchart illustrating a first embodiment of a method for determining resolution in a video call process according to an embodiment of the present invention. As shown in fig. 2, the method for determining resolution in a video call process provided by the embodiment of the present invention includes the following steps:
step 201: and in the video call process, identifying the image collected by the camera.
Specifically, the wearable device related to the embodiment of the present invention may be a smart watch, a smart bracelet, a smart wristband, or smart glasses, etc. having a video call function.
The wearable device in this embodiment may actively send a video call request, or receive a video call request sent by another device, to perform a video call service. The wearable device may send the video call request through a video call portal in the operating system or may send the video call request through an installed third party application (e.g., instant messaging software).
In the video call service, a camera of the wearable device can acquire objects in a visual field to form an image. Wearable equipment can send this image to video call's peer device to make peer device display the image that wearable equipment's camera was gathered. In the video call process, the operation power consumption of the wearable device sending the image to the opposite-end device of the video call is large.
In order to reduce power consumption in the video call process, in this embodiment, the wearable device identifies an image acquired by the camera when determining to perform a video call service.
Step 202: and when the object in the image is determined to comprise a preset first target object, reducing the resolution of the image to the first resolution to form a processed image.
In one implementation, the embodiment may use a template matching algorithm to perform image recognition. The specific process is as follows: the wearable device prestores a template of a first target object; the wearable device compares the image acquired by the camera with the template of the first target object; and when the object in the acquired image is determined to be matched with the template of the first target object, determining that the preset first target object is included in the image. For example, when the first target object is a human face, a template of the human face is stored in the wearable device in advance.
In another implementation, a machine learning algorithm may be employed for image recognition. The specific process is as follows: training an algorithm by adopting massive sample images, wherein whether the sample images comprise a first target object or not is calibrated; obtaining the result identified by the algorithm, comparing the result with the calibrated result, and determining an identification error; adjusting parameters in the algorithm according to the recognition error; and circulating the steps until the identification error is smaller than a certain error threshold value, and obtaining the finally determined machine learning algorithm.
In a specific implementation, the wearable device may determine whether a foreground object of the image includes a preset first target object. The foreground object of the image in this embodiment refers to an object which is closer to the camera and has an area in the image larger than a preset area threshold when the image is acquired. Based on the implementation mode, when image recognition is performed, the foreground object in the image can be segmented, and then whether the foreground object comprises a preset first target object or not is judged.
In this embodiment, when it is determined that the image includes the preset first target object, the resolution of the image is reduced to the first resolution, and a processed image is formed. In reducing the resolution of the image, the resolution of the image may be reduced to the first resolution on the basis of a default resolution of the image. The default resolution of the image refers to a preset default resolution. The default resolution may be set by a user, by a developer of an operating system of the wearable device, or by a developer of a third-party application that sends the video call.
In particular, the wearable device may adjust the resolution of the image by adjusting the compression ratio of the image. The higher the compression ratio of the image, the lower the resolution of the image; the lower the compression ratio of the image, the higher the resolution of the image. Therefore, in this embodiment, the wearable device may increase the compression ratio of the image to the compression ratio corresponding to the first resolution to achieve the reduction of the resolution of the image.
FIG. 3A is a schematic diagram of an acquired image in the embodiment shown in FIG. 2. As shown in fig. 3, if the first target object is a human face, the first target object is not included in the diagram a in fig. 3A, and the first target object is included in the diagram b in fig. 3A.
Step 203: and sending the processed image to equipment at the opposite end of the video call service.
Specifically, in an implementation manner, in a Peer-to-Peer (Peer-to-Peer, P2P) video call service, after forming a processed image, the wearable device directly sends the processed image to a device at an opposite end of the video call service. And selecting a corresponding network to send the processed image to the equipment of the opposite terminal based on the connection mode of the wearable equipment and the equipment of the opposite terminal.
In another implementation, in a non-P2P video call service, the wearable device sends the processed image to a server of the video call service after forming the processed image. And the server of the video call service sends the processed image to equipment at the opposite end of the video call service.
It should be noted that, in the embodiment of the present invention, the user of the wearable device may turn on or off the resolution determination mechanism during the video call. Fig. 3B is a schematic diagram of a user interface of the wearable device in the embodiment shown in fig. 2. As shown in fig. 3B, the wearable device may display a user interface 301. The user may select on the user interface 301 whether to trigger an instruction to initiate a resolution determination function during the video call. Taking the user interface 301 as an example for explanation: when the user selects 'yes', the user of the wearable device is indicated to trigger an instruction for starting a function for determining the resolution in the video call process; when the user selects "no", it indicates that the user of the wearable device has no instruction to activate the function of determining the resolution during the video call. If the user triggers an instruction to start the resolution determination function during the video call, the wearable device determines to execute step 201.
In the embodiment of the invention, the user of the wearable device or the user of the terminal device is set to open or close the resolution determination mechanism in the video call process, so that different requirements of the user can be further met, the resolution determination mechanism in the video call process can be operated when the user has requirements, and can not be operated when the user has no requirements, and the user experience is further improved.
In a specific video call process, the wearable device can also display images acquired by the camera on a screen so as to improve user experience. Accordingly, in this embodiment, the wearable device may display the processed image after forming the processed image. More specifically, the wearable device may display the processed image on an interface of a video call.
It should be noted that, when the method provided by this embodiment is also adopted by the peer device performing a video call with the wearable device, after receiving the image sent by the peer device, the wearable device downloads and displays the image, and accordingly reduces the required data amount, thereby further reducing the power consumption of the wearable device.
According to the method for determining the resolution in the video call process, provided by the embodiment of the invention, the image acquired by the camera is identified in the video call process, when the object in the image is determined to comprise the preset first target object, the resolution of the image is reduced to the first resolution, the processed image is formed, and the processed image is sent to the equipment at the opposite end of the video call service, so that the resolution of the image is intelligently reduced, the data volume sent to the equipment at the opposite end of the video call by the wearable equipment is reduced when the acquired image is determined to comprise the preset first target object in the video call process, the power consumption of the wearable equipment is reduced, and the user experience is improved.
Fig. 4 is a flowchart illustrating a second embodiment of a method for determining resolution in a video call process according to the present invention. The embodiment of the present invention provides a detailed description on how to perform the operation when the wearable device determines that the object in the image does not include the preset first target object based on the embodiment shown in fig. 2. As shown in fig. 4, the method for determining resolution in a video call process provided by the embodiment of the present invention includes the following steps:
step 401: and in the video call process, identifying the image collected by the camera.
Step 401 is similar to the implementation process and technical principle of step 201, and is not described herein again.
Step 402: and when the object in the image is determined to comprise a preset first target object, reducing the resolution of the image to the first resolution to form a processed image.
Step 402 is similar to step 202 in implementation process and technical principle, and is not described here again.
Step 403: and when the object in the image is determined not to comprise the preset first target object, the resolution of the image is increased from the first resolution to the second resolution, and a processed image is formed.
Specifically, in the video call process, the wearable device may identify, at a preset frequency, an image captured by the camera to determine whether the captured image includes a preset first target object.
When the wearable device determines that the object in the image does not include the preset first target object, the resolution of the image is increased from the first resolution to the second resolution, and a processed image is formed. Based on the description in the embodiment shown in fig. 2, the second resolution may be smaller than or equal to the default resolution, or may be larger than the default resolution, which is not limited in the embodiment of the present invention.
In a more specific implementation, when the wearable device determines that the object in the image includes the preset second target object, it determines that the object in the image does not include the preset first target object. That is, the wearable device increases the resolution of the image from the first resolution to the second resolution when it is determined that the object in the image includes the preset second target object. For example, the preset second target object may be a character, and may also be environmental information (road information, building information, vehicle information, and the like).
FIG. 5 is a schematic illustration of another captured image in the embodiment shown in FIG. 3. Taking the second target object as the text information, as shown in fig. 5, it is shown that the captured image includes the second target object.
In steps 402 and 403, it is specifically determined whether the foreground object in the image includes a preset first target object or a preset second target object. When the foreground object is determined to comprise a preset first target object, reducing the resolution of the image to a first resolution; and when the foreground object is determined not to include the preset first target object, the resolution of the image is increased from the first resolution to the second resolution. To achieve more refined management, more specifically, when it is determined that a preset second target object is included in the foreground object, the resolution of the image is increased from the first resolution to the second resolution.
In step 403, when adjusting the resolution, specifically, the wearable device may reduce the compression ratio of the image from the compression ratio corresponding to the first resolution to the compression ratio corresponding to the second resolution to form a processed image.
Step 404: and sending the processed image to equipment at the opposite end of the video call service.
Step 404 is similar to the implementation process and technical principle of step 203, and is not described herein again.
It should be noted that, in the embodiment of the present invention, both the first target object and the second target object may be preset by a user.
The above process is described below as a specific example. Assume that the wearable device is a smart watch, and the user of the smart watch is a child. The opposite-end device performing video call with the smart watch is a smart phone, and a user of the smart phone is a parent. The first target object is a portrait of a child. When the intelligent watch and the intelligent mobile phone carry out video call, the intelligent watch can identify images collected by the camera at preset frequency. When it is determined that the image includes a portrait of a child, the smart watch reduces a resolution of the image to a first resolution to save power consumption. When it is determined that the portrait of the child is not included in the image (at this time, the image acquired by the camera is considered to be the image of the environment where the child is located), the intelligent watch improves the resolution of the image from the first resolution to the second resolution, so that parents can clearly see the environment information where the child is located, the whereabouts of the child are mastered, and the safety of the child is improved. Based on the processing mode, different requirements of users can be met on the basis of saving power consumption, and user experience is improved.
According to the method for determining the resolution in the video call process, provided by the embodiment of the invention, the image acquired by the camera is identified in the video call process, when the object in the image is determined to comprise the preset first target object, the resolution of the image is reduced to the first resolution, the processed image is formed, when the object in the image is determined not to comprise the preset first target object, the resolution of the image is improved from the first resolution to the second resolution, the processed image is formed, and the processed image is sent to the equipment at the opposite end of the video call service, so that different processing on the resolution of the image is realized according to whether the image comprises the first target object, different requirements of a user can be adapted on the basis of saving power consumption, and the user experience is further improved.
