Fig. 1 is a flowchart of an embodiment of an image generation method provided in an embodiment of the present disclosure, where the image generation method provided in this embodiment may be executed by an image generation apparatus, and the image generation apparatus may be implemented as software, or implemented as a combination of software and hardware, and the image generation apparatus may be integrated in some device in an image generation system, such as an image generation server or an image generation terminal device. As shown in fig. 1, the method comprises the steps of:
step S101, receiving a first input selection signal, wherein the first input selection signal is used for selecting a first image source from at least two different types of image sources, and the different types of image sources are used for outputting different types of image data;
optionally, the first input selection signal is received from a human-computer interaction interface, and is used for selecting one first image source from at least two different types of image sources as a source of the current original image. Optionally, the at least two different types of image sources comprise at least two of a photo image source, a video image source, and an image sensor image source. Illustratively, the image sources include a picture image source, a video image source and an image sensor image source, three selection buttons may be respectively provided for the three image sources in the human-computer interaction interface, when one of the selection buttons is pressed by a user, a first input selection signal is generated, and the image source corresponding to the pressed button is selected as a source of an original image. Illustratively, when an image sensor is selected, a default image sensor, such as a front-facing camera in a mobile terminal, is directly selected; or displaying a list of image sensors for user selection. When the picture is selected, a default picture can be directly displayed or an interface is provided for a user to select a picture file in a local or network; when a video is selected, the default video may be displayed directly or an interface may be provided for the user to select a video file in the local or network.
It is to be understood that the first input selection signal may be any type of signal, which is intended to select different image sources as the sources of the original images, and the examples of the input selection signal and the image sources in the above alternative embodiments are only examples, and do not limit the present disclosure, and therefore, the details are not repeated herein.
Step S102, responding to the first input selection signal, acquiring first image data output in the first image source;
optionally, the image source includes an image sensor, a picture, and a video. When the image sensor is selected as an image source, image data is acquired from the designated image sensor, the image data output by the exemplary image sensor may be in formats such as CCIR601, CCIR656, RAW RGB, and the like, and the image data may be returned by different operating systems in different formats. Similarly, when a picture is selected as an image source, image data of the specified picture is directly acquired, and the picture can be a static picture or a dynamic picture; when a video is selected as image data, the image data of the specified video is directly acquired. The different types of image data in the image sources lead to different processing when adding image effects to the image data of different image sources in the prior art, and different processing modes are required to be specially realized for each type of image data, which is very inconvenient.
Step S103, converting the first image data into second image data of a fixed type, wherein the fixed type is the type of the image data used for loading the special effect data;
in this step, the first image data acquired in step S102 is converted into the second image data of a fixed type, so that the image data to be processed in the subsequent processing is the same data, and the processing method is the same for any type of source, and the control method for the image data of all sources can be unified. Optionally, the image data of the fixed type and the special effect data share the same storage location. Optionally, the image data of the fixed type and the special effect data are data of the same type. In an IOS system, image data of a camera, a picture and a video can be converted into CVPixelBufferRef, and because the CVPixelBufferRef and special effect data to be loaded share the same storage location, texture data in the CVPixelBufferRef can be directly replaced or modified by the special effect data, and special effect data can be conveniently loaded. Optionally, the special effect data and the CVPixelBufferRef are data of the same type, so that the corresponding image data in the CVPixelBufferRef can be directly replaced by the special effect data without other conversion, thereby facilitating subsequent special effect loading processing.
Step S104, loading special effect data on the second image data to generate third image data;
illustratively, the special effect data is color data of a pixel, and the loading of the special effect data on the second image data to generate third image data is superimposing or mixing color data represented by the special effect data on the pixel in the second image data to generate third image data; it can be understood that the special effect data may also be position data of pixels or other materials such as maps, which are not described herein again.
Step S105, generating a first special effect frame image according to the third image data.
After the third image data is generated, image rendering may be performed based on the third image data, and a frame image of a special effect is generated to be displayed on the display device. Illustratively, the third image data includes a rendering chain of the first special-effect frame image, each node in the rendering chain represents a rendering mode, the third image data further includes a material required by each node in the rendering chain, and then the first special-effect frame image is rendered according to the rendering chain and the material.
Optionally, after generating the first special effect frame image, the first special effect frame image is pushed to an asynchronous display thread, and the asynchronous display thread displays the first special effect frame image on a display device.
It can be understood that the first special effect frame image may be a special effect preview image when making a special effect of an image, or may be an image special effect generated when using a special effect package, and is not particularly limited herein.
Since the image data input from the image source may be different in resolution from the display apparatus on which the special effect image is finally displayed, the third image data needs to be scaled according to the resolution of the display apparatus to be adapted to the display apparatus. In this case, as shown in fig. 2, the step S105 includes, including:
step S201, receiving a first output control signal;
step S202, zooming the third image data according to the output control signal to obtain fourth image data;
step S203, generating the first special effect frame image according to the fourth image data.
Specifically, the first output control signal may be a default signal, that is, the first output control signal may be triggered after the third image data is obtained without being triggered by a user. For example, the size of the original image corresponding to the third image data is 800 × 600, but the size of the display screen displaying the special effect image is 480 × 320, at this time, the third image data needs to be scaled and converted into the fourth image data with the size of 480 × 320, and then the first special effect frame image is generated according to the fourth image data.
Further, as shown in fig. 3, the image generating method further includes:
step S301, receiving an input control signal;
step S302, determining whether to execute the step S104 according to the input control signal.
Alternatively, the input control signal may include one or more of an input start signal, an input end signal, an input pause signal, and an input continue signal. Inputting the second image data from a start position of the second image data in response to the second control signal being an input start signal; in response to the second control signal being an input end signal, turning off the input of the second image data; in response to the second control signal being an input pause signal, inputting second image data determined by the pause signal; and in response to the second control signal being an input continuation signal, continuing to input the second image data from a position where the second image is paused. When the input control signal is an input start signal and an input continuation signal, performing subsequent loading of special effect data on the second image data to generate third image data, and when the input control signal is an input end signal and an input pause signal, not inputting the second image data to the next step, specifically, when the input control signal is an input end signal, not inputting any second image data to the next step to generate the third image data; when the input control signal is an input pause signal, the current second image data is continuously input to the next step to achieve the pause effect of the second image data. Since the second image data does not contain the special effect data, pausing the second image data does not stop the special effect, and the special effect data is loaded into the current second image data.
Further, as shown in fig. 4, the image generating method further includes:
step S401, receiving a second output control signal;
step S402, determining whether to execute the step S104 according to the second output control signal.
Optionally, the second output control signal may include one or more of an output start signal, an output end signal, an output pause signal, and an output continue signal. Outputting the third image data from a start position of the third image data in response to the second output control signal being an output start signal; turning off the output of the third image data in response to the second output control signal being an output end signal; in response to the second output control signal being an output pause signal, outputting third image data determined by the output pause signal; in response to the second output control signal being an output resume signal, resuming output of the third image data from a position at which the third image was paused. When the second output control signal is an output starting signal and an output continuing signal, executing subsequent generation of a first special-effect frame image according to the third image data; when the second output control signal is an output end signal and an output pause signal, the third image data is not output to the next step, and specifically, when the second output control signal is an output end signal, any third image data is not output to the next step to generate the first special effect frame image; when the output control signal is the output pause signal, the current third image data is continuously input to the next step to achieve the pause effect of the third image data, and the special effect is also paused when the third image data is paused because the third image data contains the special effect data.
Further, after the step S105, the method further includes: receiving a second input selection signal for selecting a second image source from the at least two different types of image sources; acquiring fifth image data output by the second image source in response to the second input selection signal; converting the fifth image data into sixth image data of the fixed type; after the fifth image data is converted into the sixth image data, switching the image data for loading the special effect data from the second image data to the sixth image data, resulting in seventh image data generated by loading the special effect data on the sixth image data; and generating a second special effect frame image according to the seventh image data. The above steps describe the step of generating an image when switching from one image source to another image data source of a different type, in the above steps, the second input selection signal corresponds to another image source different from the current image source, and when receiving the second input selection signal, the steps are similar to the previous steps, and are not described herein again.
Further, the second image data into which the first image data is converted is stored in a first queue, and the sixth image data into which the fifth image data is converted is stored in a second queue; the step S104 includes: determining that the first queue is a queue for acquiring and loading the special effect data, acquiring the second image data from the first queue, and loading the special effect data on the second image data to obtain the third image data; the switching the image data for loading the special effect data from the second image data to the sixth image data after the fifth image data is converted into the sixth image data, resulting in seventh image data generated by loading the special effect data on the sixth image data, including: after the sixth image data is stored in the second queue, the queue for acquiring and loading the special effect data is switched from the first queue to the second queue, the sixth image data is acquired from the second queue, and the special effect data is loaded on the sixth image data to obtain the seventh image data. In the above embodiment, a queue is provided for each image source to store fixed type image data acquired from the image source, and when the image source is switched from the first image source to the second image source, before sixth image data of the second image source is not stored in the second queue, third image data is generated using the second data stored in the first queue to keep outputting the first special effect frame image, and after the sixth image data is stored in the second queue, seventh image data is generated using the sixth data stored in the second queue to generate the second special effect frame image. Therefore, when the image source is switched, the display effect cannot be influenced by the gap on the display caused by the throughput speed of the image source or the conversion speed of the image data.
Further, in the above image generation method, each of the at least two different types of image sources corresponds to a different processing thread; wherein the step S102 includes: acquiring first image data output in the first image source through a first processing thread corresponding to the first image source in response to the first input selection signal; the step S103 includes: converting, by the first processing thread, the first image data into a fixed type of second image data. Different image sources are processed by using different processing threads so as to keep the plurality of threads independent and not interfered with each other, and thus, when the image sources are switched, the same thread is not required to be switched among the plurality of image sources.

The image generation method comprises the following steps: receiving a first input selection signal for selecting a first image source from among at least two different types of image sources; acquiring first image data output in the first image source in response to the first input selection signal; converting the first image data into second image data of a fixed type, wherein the fixed type is a type of image data for loading special effect data; loading special effect data on the second image data to generate third image data; and generating a first special effect frame image according to the third image data. According to the method, after the image data of different image sources are converted into the image data of the fixed type, the special effect data are loaded on the image data of the fixed type to generate the special effect image, so that the special effect data are loaded on the image data of the same type, the loading modes are uniform, and the special effect is more convenient to load in the images of different image sources.
