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.
Example one
Fig. 1 is a schematic flow chart of an image erasing method according to an embodiment of the present invention, which is applicable to a situation that a target erasing camera can be called to erase buffered frame data stored in a video memory when a camera is switched in a game scene.
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 blooming. In order to avoid the problem, an erasing camera can be arranged, so that when the switching of the camera is detected, the erasing camera is called to erase the cache frame data stored in the display memory, and the technical problem that the mobile phone is flashed off 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. 1, the method of this embodiment includes:
and S110, when receiving an instruction of switching from the current camera to other cameras, sending a calling instruction to the target erasing camera.
The display interface may display a corresponding video frame, where the video frame may be shot by the camera a or shot by the camera B. The camera corresponding to the video frame displayed on the display interface can be used as the current camera. The other cameras are any cameras other than the current camera and the erasing camera. And generating a switching instruction when detecting a key triggering scene switching or detecting that the scene is to be switched. The target erasure camera is a camera used to erase buffered frame data. The benefits of setting up a target erasure camera are: the buffered video frame data may be deleted based on the erasure of the camera upon a camera switch.
Specifically, the camera switching instruction may be generated when an operation of triggering switching of the current camera to the other camera is detected, or when switching from the current camera to the other camera is detected. When receiving a switching instruction, the switched-to camera can be called, and meanwhile, a calling instruction can be sent to a target erasing camera, so that the target erasing camera is called to erase the buffered frame data buffered during camera switching.
Illustratively, the target erasing camera is a, the current camera is B, and the switched-to camera is C, and when an operation triggering switching from the current camera B to the other camera C is detected, a camera switching instruction may be generated. When a camera switching instruction is received, a call instruction can be sent to other cameras C, and at the same time, a call instruction can be sent to the target erasing camera a, so that the target erasing camera a can erase the buffered video frame data, that is, the frame data in the game scene.
Before the buffered frame data is erased based on the erasing camera, a target erasing camera can be created, and the attribute parameters of the target erasing camera are set, so that the target erasing camera executes a corresponding data erasing task based on the set attribute parameters.
Optionally, a target erasing camera manager in the target project, and managing the attribute information based on the target erasing camera manager; creating at least one target erasing camera to erase the buffered frame data based on the at least one camera according to the attribute information.
The target project may be a game project, that is, a created game code, and the whole code of the game may be taken as the game project, that is, the target project. An object-erasing camera manager, for example, a FreshCameraMgr manager class, can be created within the gaming project, based on which attribute information of the erasing camera can be managed. Meanwhile, a target erasing camera may be created for erasing the picture contents. When the target erasing camera runs, the canvas content can be erased frame by frame, the erasing frequency can be understood as 60 frames per second, the game interface camera draws 60 times, and the target erasing camera can also be erased 60 times. The target attribute information may include the depth value of the target erasure camera, i.e., the lowest depth; it may also include setting the camera clear mode to SolidColor. Meanwhile, the background color of the object-erasing camera may be set to a solid color, for example, black. The purpose of setting the background color as the pure color is to avoid the problems of display leakage and upper penetration when the target erasing camera works.
Specifically, at least one globally usable target erasure camera may be created in advance, and a manager of the target erasure cameras may be created at the same time. Meanwhile, it is possible to set the attribute information of the target erasing camera and manage the set attribute information based on the target erasing camera manager.
For example, referring to fig. 2, an erasing camera may be created, and the attribute information of the erasing camera includes a camera refresh parameter, i.e., a clearing mode; the depth of the camera, the depth value may be-1. The manager of the target erasing camera also comprises an interface and an ID (identity) of the erasing camera and the calling camera which are independently used globally, the camera is called based on the camera calling interface, and the target erasing camera can be called based on the ID.
In this embodiment, when receiving an instruction to switch from the current camera to another camera, sending a call instruction to the target erasing camera includes: when a switching instruction for switching from the current video camera to other video cameras is received, a camera interface corresponding to the target erasing video camera is called, and a calling instruction is sent to the target erasing video camera based on the camera interface.
The camera interface may be an interface for calling the target to erase the camera. The camera may be invoked based on the camera interface. In order to call the target erasing camera, the target erasing camera may also be called according to the ID of the target erasing camera. The calling instruction is an instruction corresponding to the target erasing camera, and the target erasing camera can be called based on the calling instruction.
Specifically, when an instruction for switching from the current video camera to another video camera is received, the manager for the target erasing video camera may call the camera interface of the target video camera, and send a call instruction to the ID of the target erasing video camera.
And S120, starting the target erasing camera based on the calling instruction, and erasing the cached frame data based on the target erasing camera.
The video memory may also be referred to as a frame buffer. The video memory can be used for storing rendering data processed or to be extracted by the video card chip, namely the video memory is a component used for storing image information to be processed. The buffered frame data may store data in a video memory.
It should be noted that, since the target erasing camera is required to erase the buffered frame data during the camera switching, the target erasing camera can be earlier than the camera operating time to which the camera is switched. Of course, the system may also work simultaneously with the switched camera, as long as the buffered frame data stored in the graphics card can be deleted.
Specifically, after the target erasing camera receives the call instruction, the target erasing camera may be started. When the target erasing camera works, the frame data buffered in the display memory can be erased.
In this embodiment, the erasing the buffered frame data based on the target erasing camera includes: erasing the buffered frame data according to attribute information corresponding to the target erasure camera.
The attribute information may be parameter information of a preset target erasing camera.
Specifically, the target erasing camera erases the cached frame data according to preset attribute information.
On the basis of the above technical solution, the erasing the cached frame data according to the attribute information corresponding to the target erasing camera includes: and erasing full-screen data based on the depth value in the target erasing camera, erasing the cached frame data based on an erasing parameter, and setting the erased background as a preset color according to the background parameter.
Wherein the preset color may be black. The advantage of setting to black is that, avoids the display to deposit and reveals, leads to the problem that the image worn the group. Full screen data may be erased based on the depth value.
Specifically, after the target erasing camera is called, the target erasing camera may erase full-screen data in the display memory according to preset attribute information, for example, according to a depth value in the attribute information; the erased background color may be set to a preset color, such as black, according to the background parameter in the attribute information.
On the basis of the above technical solution, the attribute information further includes a task execution duration, and the erasing of the cached frame data based on the target erasing camera includes: determining the working time of the target erasing camera according to the preset task execution time; and based on the working duration, erasing the cached frame data in the working duration, wherein the task execution duration can be the working duration of the erasing camera, namely the preset duration. The duration of operation may be one minute, two minutes, five minutes, etc., i.e., the target-erasing camera may be operated at all times.
Specifically, after the target erasing camera is called, the operation of erasing the cached frame data can be continuously executed according to the preset task execution duration, namely the target erasing camera duration, until the actual erasing duration reaches the preset duration.
For example, if the target erasing camera is continuously working, when a camera switching instruction is received, the buffered frame data can be erased directly based on the erasing camera; if the continuous working time of the target erasing camera is 2min, the target erasing camera can continuously work for 2min after being started, namely the target erasing camera can continuously work for two minutes to delete the cached frame data in the display memory. At this time, the technical effect that can be achieved is that no screen is needed. Meanwhile, when the mobile terminal plays the game, the problems of display memory shackle, jamming or flash back can be avoided.
According to the technical scheme of the embodiment of the invention, when the current camera is switched to other cameras, the starting instruction can be sent to the target erasing camera, so that the target erasing camera can delete the video frame data cached in the display memory, the problems that in the prior art, when the cameras are switched, the video frame data cached in the display memory are overlapped, and therefore the screen is blurred, and when a game is installed on a mobile terminal, the technical problems of jamming, downtime and backslash of the mobile terminal exist are solved, the corresponding images can be displayed when the cameras are switched, meanwhile, the problems of jamming and backslash of the mobile terminal can be avoided, and further, the technical effect of user experience is improved.
