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 to be construed as limiting 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.
Example one
Fig. 2 is a flowchart of an image erasing method according to an embodiment of the present invention, which is applicable to a situation where, when a drawing camera in a game scene is switched, an erasing camera bound to the drawing camera is called to erase buffered frame data stored in a video memory, where the method may be executed by an image erasing apparatus, and the image erasing apparatus may be implemented by software and/or hardware, and may be integrated in an electronic device such as a computer or a server.
Before the technical solution of the present embodiment is described, an application scenario may be exemplarily described. The scene in the game and the image displayed on the display interface can be constructed by a plurality of cameras, for example, the near view and the far view can adopt different cameras to shoot corresponding images, and after the images are shot, the images can be sent to the camera corresponding to the main screen, so that the camera corresponding to the main screen can display the images on the display interface. In the process of practical application, there is a case where the camera is switched at the time of image display. When the camera lens is switched, the buffered frame data in the display memory may be superimposed, that is, the buffered frame data stored in the display card is more, which may cause a problem of screen splash. In order to avoid the problem, the erasing camera can be arranged to call the erasing camera to erase the cache frame data stored in the display memory when the switching of the camera is detected, so that the technical problem that the mobile phone is flashed back due to the fact that a display screen is displayed or the number of data stored in the display memory is large is avoided.
As shown in fig. 2, the method of the present embodiment includes:
s110, when the operation of triggering switching from the current drawing camera to the target drawing camera is detected, sending a switching instruction to the target drawing camera and starting a target erasing camera bound by the target drawing camera.
The current drawing camera may be a camera that draws a current-time game scene, and is used to render a corresponding picture of the current-time game scene. For example, the current camera draws a game scene 1. The current drawing camera may be a camera corresponding to the current video picture, that is, the current drawing camera may be configured to render a video frame, i.e., a game picture, at the current time and under the visual angle of the current drawing camera. That is, the display interface may display a corresponding video frame, which may be captured by the camera a or the camera B. The camera corresponding to the video frame displayed on the display interface can be used as the current drawing camera. The target drawing camera may be a camera for drawing a future time game scene, and is configured to render a picture corresponding to the future time game scene. For example, the target rendering camera renders game scene 2. The target rendering camera may be a camera corresponding to a video picture at a future time, that is, the target rendering camera may be configured to render a video frame under a visual angle of the camera at the future time. That is, the target drawing camera is any drawing camera except for the current drawing camera and the erasing camera bound to the current drawing camera.
It should be noted that the current rendering camera may include one, two, and more than two rendering cameras, and the target rendering camera may include one, two, and more than two rendering cameras.
The switching instruction may be understood as an instruction to switch the current drawing camera to the target drawing camera. And generating a switching instruction when detecting a key triggering scene switching or detecting that the scene is to be switched. The target-erasing camera may be used to erase the game video frame rendered by the current drawing camera before the target-drawing camera renders the game view. In order to erase the buffered frame data in the video memory before operating the corresponding rendering camera, an erase camera may be bound to each rendering camera.
In the present embodiment, there are various ways of triggering an operation of switching from the current rendering camera to the target rendering camera and generating a corresponding instruction. For example, a trigger area may be set in advance, and when a user triggers any position in the trigger area, a command for switching from the current camera to another camera may be generated; a trigger button can be preset, and when a user triggers the preset trigger button, an instruction for switching from the current camera to other cameras can be generated; or the following steps: the operation of switching from the current drawing camera to the target drawing camera is triggered in a voice mode, and when a user triggers a preset trigger operation, an instruction for switching from the current camera to other cameras can be generated.
Wherein, the purpose of switching from the current drawing camera to the target drawing camera is as follows: the method comprises the following steps of realizing mutual switching among different scenes (for example, switching scene 1 into scene 2), and/or realizing mutual switching among game interfaces corresponding to different drawing camera visual angles in one scene (for example, switching a top view visual angle into an orthogonal visual angle). The purpose of sending a switching instruction to a target drawing camera and starting an erasing camera bound by the target drawing camera is as follows: and erasing game video frame data stored in the video memory before the target drawing camera renders the game picture, namely erasing the video frame cached in the video memory when the current drawing camera displays the video frame, so as to avoid the phenomenon of memory overflow.
Specifically, the switching operation for switching the camera is preset, for example, the pre-trigger operation includes sliding a screen, double-clicking a screen, and the like, after the switching trigger operation is set, the operation of the player may be obtained in real time, and when it is detected that the operation of the player is the preset trigger operation, a switching instruction for switching from the current drawing camera to the target drawing camera may be generated. When the switching system receives the switching instruction, the target drawing camera can be called according to the received switching instruction, namely the switching instruction is sent to the target drawing camera and the target erasing camera bound with the target drawing camera, so that the target drawing camera is started, and the target erasing camera erases the cache frame data in the video memory.
Illustratively, the current drawing camera is a, the target drawing camera is B, and the target erasing camera bound by the target drawing camera is B1, and when an operation of triggering switching from the current camera a to the target drawing camera B is detected, a drawing camera switching instruction may be generated. When a drawing camera switching instruction is received, a call or start instruction may be sent to the target drawing cameras B and B1 to start the target drawing camera B, and the target erasing camera B1 bound to the target drawing camera may be started to erase the buffered frame data of the dyed game picture by the target erasing camera.
And S120, erasing the cache frame data in the video memory by the target erasing camera based on the switching instruction, and enabling the target drawing camera to work based on the switching instruction.
The video memory may also be referred to as a frame buffer. The display memory can be used for storing rendering data processed or to be extracted by the display card chip, namely the display memory is a component used for storing image information to be processed. The buffered frame data may store data in a video memory.
Specifically, when the target drawing camera receives the switching instruction, when it is detected that the target erasing camera bound to the target drawing camera is in a starting state, the target erasing camera may erase the buffered frame data in the display memory, and optionally, after the target erasing camera erases the buffered frame data in the display memory, the target drawing camera may operate according to the switching instruction received by the target drawing camera, so as to implement switching of the current drawing camera to the target drawing camera.
Optionally, the causing the target erasing camera to erase the buffered frame data in the video memory based on the switching instruction includes: when a target erasing camera receives a switching instruction, the target erasing camera starts to erase the cached frame data in the display memory; and when the detected working time of the target erasing camera reaches the preset time threshold, stopping working.
Wherein the duration threshold may be a duration (e.g., 500 milliseconds) set empirically.
Specifically, a working time threshold of the target erasing camera is preset, when the target erasing camera receives a switching instruction, the target erasing camera starts to erase the cached frame data in the video memory, the working time of the target erasing camera is recorded, and when the working time of the target erasing camera reaches the preset time threshold, the working of the target erasing camera is stopped.
Illustratively, the threshold operating time for the target erasure camera is preset to be 500 milliseconds. The time corresponding to the start of erasing the buffered frame data in the video memory by the target erasing camera is 9 points, 10 minutes, 0 seconds and 0 milliseconds, and when the working time of erasing the buffered frame data in the video memory by the target erasing camera is 9 points, 10 minutes, 0 seconds and 500 milliseconds, the working of the target erasing camera is stopped.
Currently, the working time length of the target erasing camera is determined, which may also be determined by a preset number of buffer frames, and optionally, an erasing frame number threshold of the target erasing camera may be preset, and optionally, 30 frames.
Specifically, when the target erasing camera receives the switching instruction, the target erasing camera starts to erase the cached frame data in the video memory, records the number of the video frame frames of the target erasing camera, and stops the work of the target erasing camera when detecting that the number of the video frame erased by the target erasing camera reaches the preset erasing frame number threshold.
Illustratively, the threshold of the number of erasing frames of the target erasing camera is preset, and optionally, the threshold of the number of erasing frames is 20 frames. And when the number of the erasing frames of the buffer frame data in the erasing video memory of the target erasing camera reaches 20 frames, stopping the work of the target erasing camera.
According to the technical scheme of the embodiment of the invention, when the operation of triggering the switching from the current drawing camera to the target drawing camera is detected, the switching instruction is sent to the target drawing camera and the target erasing camera bound by the target drawing camera is started, the target erasing camera erases the cache frame data in the display memory based on the switching instruction and works based on the switching instruction, so that the problem that the cache frame data in the display memory are overlapped to cause screen splash in the prior art when the cameras are switched is solved, and the technical problems of jam, downtime and flash backing of the mobile terminal exist when a game is installed on the mobile terminal.
Example two
Fig. 3 is a schematic flow chart of an image erasing method according to a second embodiment of the present invention, and based on the foregoing embodiment, when it is detected that a plurality of target erasing cameras are started, the technical solution of the present embodiment may be implemented.
The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 3, the method of the present embodiment may include:
s210, when the operation of triggering switching from the current drawing camera to the target drawing camera is detected, sending a switching instruction to the target drawing camera and starting a target erasing camera bound by the target drawing camera.
S220, enabling the target to erase the cache frame data in the video memory based on the switching instruction, and enabling the target to draw the camera to work based on the switching instruction.
And S230, when the at least two target erasing cameras are detected to work, reserving one target erasing camera to work according to the starting time of the at least two target erasing cameras. Illustratively, the drawing camera a is bound with the erasing camera A1, the drawing camera B is bound with the erasing camera B1, and the drawing camera C is bound with the erasing camera C1. The working time threshold value of the erasing camera is preset to be 2 seconds. When the drawing camera a with 9 dots and 10 minutes and 30 seconds is switched to the drawing camera B, the start time of the erasing camera B1 is 9 dots and 10 minutes and 30 seconds. When the camera B is switched to the camera C at 9 dots, 10 minutes, and 31 seconds, the start time of the erasing camera C1 is 9 dots, 10 minutes, and 31 seconds. The working time of B1 for erasing the shot at 9 points, 10 minutes and 31 seconds is 1 second and less than 2 seconds, so that when the B1 and the C1 are in working state at 9 points, 10 minutes and 31 seconds, the B1 is stopped to work, and the C is kept to work. That is, the reason why two or more target erasing image capturing operations are caused is that: and the switching interval time between the drawing cameras is less than the working time length threshold value of the preset target erasing camera. The benefit of keeping a target erase camera operational is to improve video memory erase performance.
Specifically, the number of target erasing cameras in the working state is acquired, when the number of the target erasing cameras in the working state is detected to be two or more, the working starting time of the target erasing cameras in the working state is acquired, the latest started target erasing camera is reserved to work according to the starting time of the target cameras, and the work of the target erasing cameras except the latest started target erasing camera is stopped, so that the latest started target erasing camera erases the cache frame data in the display memory.
Optionally, before the step of detecting that the operation of switching from the current drawing camera to the target drawing camera is triggered, the image erasing method of this embodiment further includes: and creating at least one erasing camera, and respectively setting the attribute parameters of each erasing camera so as to enable the at least one target erasing camera to erase the cached frame data in the video memory based on the attribute parameters.
The attribute parameters may be preset attribute parameters for erasing the camera, and the attribute parameters for erasing the camera may include a camera erasing parameter, a camera depth value, and a background parameter of the camera. The camera erasing parameter is used for erasing the buffered frame data. The camera depth value is used to erase full screen data. The background parameter of the camera is used to set the erased background to a preset color (e.g., black). It should be noted that the attribute parameters of each erasure camera may be the same or different.
Specifically, the number of the drawing cameras is obtained, the erasing cameras with the same number as the drawing cameras are created according to the number of the drawing cameras, the camera erasing parameters, the camera depth values and the camera background parameters of each erasing camera are preset, and the target erasing camera erases the cache frame data in the display memory based on the attribute parameters according to the erasing parameters, the camera depth values and the camera background parameters of the erasing cameras.
Optionally, the causing the target erasing camera to erase the buffered frame data in the video memory based on the switching instruction includes: setting the erasure camera based on the depth value; and erasing the cached frame data corresponding to the display interface camera based on the erasing parameters, and setting the erased background as a preset color according to the background parameters.
The camera erasing setting based on the depth value aims to set the erasing camera in a drawing layer corresponding to the preset depth value, so that the erasing camera erases the cached frame data corresponding to the display interface camera based on the erasing parameters. The display interface camera is used for drawing a camera of a screen display picture. The preset color may be black. The black setting has the advantage that the problem that the image wears the upper due to leakage of the display memory is avoided.
Specifically, the drawing layer corresponding to the camera is determined to be erased according to the depth value of the camera, the camera is erased according to the drawing layer corresponding to the camera, and the full-screen data is erased according to the depth value in the camera. And according to the cached frame data corresponding to the erasing display interface camera of the erasing camera, setting the erased background to be a preset color according to the background parameter of the erasing camera, so that the target erasing camera erases the cached frame data in the display memory based on the attribute parameter.
Optionally, after the creating at least one erasing camera, the method further includes: and binding each erasing camera with the corresponding drawing camera of the drawing layer, and creating a binding relationship between the erasing camera and the drawing camera so as to search the corresponding target erasing camera based on the binding relationship of the camera identifier of the target drawing camera when the target drawing camera is detected to be switched.
The drawing layer can be understood as a drawing layer corresponding to a rendering picture of the camera. The purpose of creating the binding relationship between the erasing camera and the drawing camera is to search for a corresponding target erasing camera based on the binding relationship of the camera identifier of the target drawing camera when the switch to the target drawing camera is detected.
Specifically, according to the camera identifier of the drawing camera and the camera identifier of the erasing camera, each erasing camera is bound with the drawing camera of the corresponding drawing layer, and a binding relationship between the erasing camera and the drawing camera is created. Optionally, the binding relationship between the erasing camera and the drawing camera is created and stored in the configuration file.
Illustratively, the camera identifier of the drawing camera a is AA, the camera identifier of the drawing camera a binding and erasing camera A1 is AA1, the camera identifier of the drawing camera B is BB, and the camera identifier of the drawing camera BB binding and erasing camera B1 is BB1. And establishing binding relations between AA and AA1, and between BB and BB1.
Optionally, the image erasing method of this embodiment further includes: an erasure camera manager is created.
The camera erasing manager can be used for managing the binding relationship between the camera identification for drawing and shooting and the camera erasing manager.
Optionally, the creating and erasing camera manager includes: and determining the camera identification of each drawing camera, and binding the camera identification with the corresponding erasing camera to obtain the binding relationship among the camera identification, the erasing camera and the drawing camera.
Specifically, the camera identifier of the drawing camera, the camera erasing, and the binding relationship between the drawing cameras may be established in advance. And determining the camera identification of each drawing camera according to the camera identification of each drawing camera, binding the camera identification of each drawing camera with the erasing camera corresponding to the drawing camera according to the camera identification of each drawing camera and the corresponding relation between each drawing camera and the erasing camera, and obtaining the camera identification of each drawing camera and the erasing camera bound by each drawing camera according to the camera identification of each drawing camera and the erasing camera correspondingly bound by each drawing camera.
Correspondingly, when the operation of triggering switching from the current drawing camera to the target drawing camera is detected, sending a switching instruction to the target drawing camera and sending a switching instruction to the target erasing camera bound with the target erasing camera includes: when the operation of triggering switching from the current drawing camera to the target drawing camera is detected, determining a target erasing camera bound with the target drawing camera based on the binding relation so as to erase the cache frame data in the video memory based on the target erasing camera.
Specifically, when the operation of triggering switching from the current drawing camera to the target drawing camera is detected, the binding relationship among the camera identification of the drawing camera, the erasing camera and the drawing camera is pre-established according to the erasing manager, and the target erasing camera bound with the target drawing camera is determined so as to erase the cache frame data in the video memory based on the target erasing camera.
According to the technical scheme, when at least two targets are detected to erase the camera to work, one target is reserved to erase the camera to work according to the starting time of the at least two targets to erase the camera, the technical problems that in the prior art, when the camera is switched, buffered video frame data in a display memory are overlapped to cause screen splash are solved, and when a game is installed on a mobile terminal, the mobile terminal is stuck, crashed and flashed are solved.
EXAMPLE III
Fig. 4 is a schematic diagram of a preferred image erasing method according to a third embodiment of the present invention. The technical terms that are the same as or corresponding to the above-mentioned embodiments are not described in detail herein.
As shown in fig. 4, when it is detected that the camera corresponding to the main interface of the Mainpage bridge is switched to the camera corresponding to the game level selection main interface, or the camera corresponding to the game level selection main interface is switched to the camera corresponding to the main interface InLevel in the game level, that is, as long as the camera switching is detected, the camera erasing system provided in this embodiment, that is, the camera system corresponding to the target erasing camera, may be called to execute the present technical solution, so as to solve the problem of video memory leakage during camera switching in the prior art.
The method of this embodiment may specifically include:
the camera erasing manager can be created first, and the manager is used for managing the camera erasing, so that the camera erasing can be created first, and the specific way of creating the camera erasing can be as follows: a wipe camera component class that inherits the Monobehavior class in unity, i.e., the refreshcamerara component class, can be created. And declaring a camera identification (camera id) of a drawing camera needing to be bound, a name of the camera, and calling, registering, erasing a camera interface and a time control interface in the erasing camera component class. The time control interface aims to transmit the working time of erasing the camera and the working time of transmitting a target erasing the camera.
At least one camera instance type can be created as rfcamerabj, the component refreshpamra is hung on the rfcamerabj camera, the rfcamerabj camera is bound with the drawing cameras in the game, one rfcamerabj camera is newly added to each parent node of the cameras MainCamera, battercameracroot and the like, and the component refreshpara is hung on the rfcamerabj camera, that is, each drawing camera is bound to one erasing camera. For example, the game master camera node binds the MainCamera game master render camera with the RFMainCamera erase camera, and the game battle camera node binds the battle camera game battle render camera with the rfbattle camera. The method has the advantage of facilitating the calling of the erasing camera bound with the drawing camera based on the binding relationship between the drawing camera and the erasing camera.
The camera refresh mode clearFlag for instance RFCameraObj inside the refreshname component class can be set to solidolor (clear) and the depth of the camera set to-1 so that the hierarchy is the lowest.
The establishing of the binding relationship may be: a binding erasure camera manager RefeshCameraBindingMgr may be created to cause cameras in the game to make an associated registration.
