Hereinafter, a kind of image processing method provided by the embodiments of the present application will be elaborated in conjunction with specific embodiments, as described in Figure 3, which includes:
S300, in the operational process of target application, image processing apparatus obtains image frame sequence to be processed.
Wherein, above-mentioned target application can be any application that image operation is carried out dependent on GPU installed in image processing apparatus.What the target application can be downloaded for user from third-party application market, or the included application of image processing apparatus system, the embodiment of the present application are not especially limited this.
Illustratively, target application is AutoCAD (Auto Computer Aided Design), 3Ds Max (3D Studio Max), Pro/Engineer or video player etc..
Image frame sequence to be processed includes multiple picture frames to be processed.Since the type of target application is different, image processing apparatus can be directly obtained institute's picture frame to be handled that the image frame sequence to be processed includes, this can also be not especially limited each of image frame sequence to be processed picture frame to be processed, the embodiment of the present application in real time.
Illustratively, target application is live video player, it includes all multielements such as character moulding, environmental background that live video player, which needs the content presented for user, and during playing live video, image processing apparatus shows these elements by rendering different picture frames.Since live video is to show image in a manner of frame, image processing apparatus needs to obtain each picture frame to be processed in real time.
S301, image processing apparatus sequentially generate calculation command queue and the rendering command queue of each picture frame to be processed in image sequence to be processed.
For each picture frame to be processed, image processing apparatus is after getting the picture frame to be processed, all calculation commands of the picture frame to be processed are put into the calculation command queue of the first preset kind, it and by the picture frame to be processed is that all renderings order is put into the rendering command queue of the second preset kind, in this way, producing calculation command queue and the rendering command queue of the picture frame to be processed.
From the description of S300 it is found that image processing apparatus can obtain each picture frame to be processed in real time, institute's picture frame to be handled that image frame sequence to be processed includes can also be directly obtained.No matter image processing apparatus uses which kind of above-mentioned mode to obtain picture frame to be processed, which generates calculation command queue and the rendering command queue of each picture frame to be processed according to the sequencing for the time for obtaining picture frame to be processed.
Specifically, the CPU that operational objective is applied in image processing apparatus generates calculation command queue and the rendering command queue of each picture frame to be processed.
For each picture frame to be processed, CPU is after the calculation command queue and rendering command queue for generating the picture frame to be processed, GPU into image processing apparatus sends calculation command queue and the rendering command queue of the picture frame to be processed, in this way, GPU can be according to the calculation command queue got, calculate all pixels of the picture frame to be processed, and GPU is according to the rendering command queue got, the picture frame to be processed is rendered, and shows the picture frame to be processed after rendering on the display of image processing apparatus.
For ease of description, the embodiment of the present application is illustrated so that GPU obtains the first calculation command queue and the first rendering command queue as an example.Wherein, the first rendering command queue includes multiple rendering orders corresponding with n-th picture frame, N > 1.First calculation command queue includes multiple calculation commands corresponding with the N+1 picture frame.Here, n-th picture frame and the N+1 picture frame are the picture frame to be processed of foregoing description.
S302, image processing apparatus GPU the rendering order that includes of the first rendering command queue is executed using first thread, render n-th picture frame.
In conjunction with foregoing description, a free time SM unit (referred to as are as follows: the first SM unit) in the GPU of image processing apparatus executes the rendering order that the first rendering command queue includes using first thread, to complete the rendering task of n-th picture frame, the rendering of n-th picture frame is realized.
Specifically, the method for the first SM unit rendering n-th picture frame are as follows: the first SM unit according to preset algorithm, calculates the characteristic value of the first rendering command queue first；Then, whether the first SM unit judges are locally stored with the characteristic value of other the rendering command queues equal with the first rendering characteristic value of command queue.
If the characteristic value of the first rendering command queue is equal with the target of storage rendering characteristic value (referred to as the first numerical value) of command queue, target rendering command queue includes multiple rendering orders corresponding with X (X >=1 N >) a picture frame, then illustrate that n-th picture frame and X picture frame repeat, first SM unit can directly render n-th picture frame using the rendering result of X, ground picture frame, and rendering result may include textures information and shadow information etc..Correspondingly, rendering result of the first SM unit from local acquisition target rendering a picture frame of the corresponding X (X >=1 N >) of command queue, and the rendering result of X, base area picture frame renders n-th picture frame.In this scene, the process of rendering n-th picture frame no longer needs to additionally occupy hardware resource, and the hardware resource occupied when can reduce image rendering reduces the power consumption of image processing apparatus.
If the local not stored feature for having other the rendering command queues equal with the first rendering characteristic value of command queue
