It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0029] It should be noted that the execution subject of the following method embodiment may be an image generating device, which may be implemented as part or all of an electronic device through software, hardware, or a combination of software and hardware. Optionally, the electronic device may be any electronic device capable of processing images, such as a desktop computer, a smart phone, a personal digital assistant, and a tablet computer. Of course, the electronic device may also be an independent server or a server cluster composed of multiple servers. The following method embodiment is described by taking the execution subject as an electronic device as an example.

[0030] Figure 1 A flowchart of an image generation method provided by an embodiment of the present invention. This embodiment relates to a specific process of how an electronic device obtains a target image of a target object. Figure 1 As shown, the method may include:

[0031] S101 . Generate sub-images of the target object in sequence.

[0032] Specifically, in order to facilitate the user to view the target object on the electronic device, the electronic device can convert the target object into a target image, wherein the target object can be various types of documents, such as a word document and a portable document format (PDF) document, etc., and the target object can also be a plurality of web page contents that need to be viewed and a plurality of images that need to be viewed, etc. For example, the electronic device can convert a word document into a target image, convert a PDF document into a target image, and convert a plurality of web page contents that need to be viewed into a target image.

[0033] As an optional implementation, the process of an electronic device sequentially generating sub-images of a target object may be: controlling the view control of the target object to move to the target content of the target object that has not been displayed on the screen; obtaining the sub-image corresponding to the target content, and returning to the step of controlling the view control of the target object to move to the target content of the target object that has not been displayed on the screen, until all contents of the target object are displayed and all sub-images of the target object are obtained.

[0034] Among them, the electronic device can generate a sub-image sequence of the target object through a view control. In the Android system, the view control is View. The electronic device obtains the target content in the target object by controlling the movement of the view control, so that the view control moves to the target content of the target object that has not been displayed on the screen. For the target content currently displayed on the screen, the electronic device can use a corresponding image acquisition method to obtain the sub-image corresponding to the target content. Optionally, the electronic device can use a screenshot method to obtain the sub-image corresponding to the target content. Specifically, the electronic device calls the interface of the screenshot system to obtain the sub-image corresponding to the currently displayed target content through the screenshot system. After obtaining the sub-image corresponding to the currently displayed target content, the electronic device returns to the above-mentioned step of controlling the view control of the target object to move to the target content of the target object that has not been displayed on the screen, and repeats the above process until all the contents of the target object are displayed, thereby obtaining all the sub-images of the target object.

[0035] As another optional implementation, for a target object that can be rendered into an image, the electronic device can sequentially generate each sub-image of the target object by using an image rendering method. In this case, the process of sequentially generating each sub-image of the target object by the electronic device can be: reading target content that has not been rendered in the target object; rendering the target content into a corresponding sub-image, and returning to the step of reading target content that has not been rendered in the target object, until all the contents of the target object are rendered, and all the sub-images of the target object are obtained.

[0036] S102. Writing the sub-images into an image file in an external memory in sequence according to the order of the sub-images in the target object to obtain a target image corresponding to the target object.

[0037] The external memory is relative to the running memory of the electronic device, and the external memory may be a disk memory, such as a hard disk, a floppy disk, an optical disk, and a USB flash drive. The image file may include a file header and a file body, wherein the file header may include the size information of the image file, and the file body is used to store a sub-image sequence of the target object. The file format of the image file may be a Joint Photographic Experts Group (JPEG) format, a Graphics Interchange Format (GIF) format, and an image file storage format (Portable Network Graphic Format, PNG) format, etc.

[0038] After obtaining the sub-image of the target object, the electronic device directly writes the sub-image into the image file of the external memory based on the order of the sub-image in the target object, that is, automatically splicing the sub-image with the current last sub-image in the image file in the external memory. After the splicing is completed, the sub-image is the current last sub-image in the image file. After the electronic device obtains the sub-image of the target object again, the electronic device continues to write the sub-image obtained this time into the above image file according to the above process. In other words, the electronic device obtains each sub-image of the target object in sequence, and writes each sub-image into the above image file in sequence according to the order of each sub-image in the target object, thereby realizing automatic splicing of each sub-image.

[0039] Optionally, before the above S102, the method may further include: the electronic device obtains the order of each sub-image in the target object.

[0040] When the electronic device generates each sub-image of the target object through the view control, the electronic device controls the view control to move to the target content of the target object that has not been displayed on the screen, obtains the position of the target content in the target object, and determines the order of the sub-images corresponding to the target content based on the position. For the order of other sub-images, the order of the sub-images corresponding to the target content can be referred to.

[0041] When the electronic device sequentially generates each sub-image of the target object by image rendering, the electronic device reads the target content that has not been rendered in the target object, and at the same time, obtains the position of the target content in the target object, and determines the order of the sub-images corresponding to the target content based on the position. For the order of other sub-images, the order of the sub-images corresponding to the target content can be obtained by referring to the method of obtaining the order of the sub-images corresponding to the target content.

[0042] It can be seen from the above process that the electronic device directly realizes the splicing of each sub-image of the target object in the external memory, and after obtaining a sub-image of the target object, the sub-image is directly written into the external memory for splicing based on the order of the sub-image, without the need to use memory splicing technology, which greatly reduces the occupation of the running memory. When a large target object needs to be converted into an image, especially for electronic devices with limited memory, the success rate of image generation is greatly improved.

[0043] Since each sub-image is spliced ​​in the image file in sequence, each sub-image can be stored in the image file in the form of a one-dimensional vector. Therefore, in order to display the target image normally later, the electronic device needs to store the size information of the target image in the file header of the image file. To this end, based on the above embodiment, optionally, the method may also include: determining the target length and target width of the target image; writing the target length and target width into the file header of the image file. Optionally, the process of S102 may be: according to the order of each sub-image in the target object, each sub-image is sequentially written into the image file of the external storage device by vertical splicing or horizontal splicing to obtain the target image of the target object.

[0044] Among them, the target length refers to the length of the target image in the vertical direction, and the target width refers to the length of the target image in the horizontal direction. When the electronic device uses a vertical splicing method to splice each sub-image, the electronic device can add the lengths of all sub-images to determine the target length, and determine the maximum width in each sub-image as the target width. When the electronic device uses a horizontal splicing method to splice each sub-image, the electronic device can determine the maximum length in each sub-image as the target length, and add the widths of all sub-images to determine the target width. After obtaining the target length and target width of the target image, the electronic device writes the target length and target width into the file header of the image file. In this way, when the target image is displayed subsequently, the electronic device can read the target length and target width in the file header of the image file, load the data in the file body based on the target length and target width, and display the target image.

[0045] The image generation method provided by the embodiment of the present invention sequentially generates each sub-image of the target object, and sequentially writes each sub-image into the image file of the external memory according to the order of each sub-image in the target object, so as to obtain the target image corresponding to the target object. That is to say, after each sub-image is obtained, the electronic device will directly write the sub-image into the image file of the external memory according to the order of the sub-image in the target object, so as to automatically complete the splicing of each sub-image of the target object in the external memory. Compared with the traditional method of needing to complete the splicing of all sub-images in the running memory and then write them into the disk memory, the overhead of the running memory is greatly reduced, thereby improving the success rate of image generation.

[0046] In practical applications, in order to increase the speed of generating the target image, the electronic device may execute the writing step of the current sub-image of the target object and the generating step of the next sub-image of the target object in parallel. Based on the above embodiment, optionally, the above S102 may include:

[0047] S1021. According to the first order of the current sub-image of the target object in the target object, write the current sub-image into an image file in an external memory, and generate a next sub-image of the target object.

[0048] Among them, after obtaining the current sub-image of the target object, the electronic device writes the current sub-image into the image file of the external memory based on the first order of the current sub-image in the target object. At the same time, the electronic device immediately generates the next sub-image of the target object without waiting for the current sub-image to be written into the image file before generating the next sub-image.

[0049] S1022. Obtain a second order of the next sub-image in the target object, and write the next sub-image into the image file according to the second order until the last sub-image of the target object is written into the image file, thereby obtaining a target image of the target object.

[0050] For example, it is assumed that the current sub-image of the target object obtained by the electronic device is matrix 1 The electronic device directly writes the current sub-image into the image file of the external memory in the order of the current sub-image in the target object. The specific storage form of the current sub-image in the image file can be [1,2,3,4,5,6,7,8,9]. While writing the current sub-image, the electronic device also continues to generate the next sub-image of the target object. Assume that the next sub-image of the target object is matrix 2 The electronic device writes matrix 2 into the above image file in the order of the next sub-image. At this time, the data in the file body of the image file is updated to [1,2,3,4,5,6,7,8,9,1,2,3,3,2,1,7,8,9]. Further, assuming that the electronic device uses vertical splicing to splice the sub-images, and assuming that the target object includes 2 sub-images, the target length determined by the electronic device is the sum of the lengths of the above sub-images, and the target width is the maximum width of each sub-image. In this way, the electronic device determines the target length of the target image (the target image is the image after the target object is converted) as 6 and the target width as 3. The electronic device writes the target length and target width of the target image into the file header of the image file. In this way, the electronic device can load the data in the image file based on the target length and target width to display the target image. The target image displayed at this time can be

[0051] In practical applications, in order to further reduce the overhead of the running memory in the image generation process, based on the above embodiment, optionally, after writing the current sub-image into the image file in the external memory, the electronic device can also release the memory space occupied by the current sub-image in the running memory.

[0052] In this way, when generating the next sub-image of the target object, the electronic device can re-apply to the running memory for the memory space required for the next sub-image. It can be understood that during the entire image generation process, the size of the memory space occupied by the electronic device in the running memory is the same as the size of a sub-image. Compared with the method of stitching all sub-images in the running memory and then writing them to the disk storage, the running memory overhead is greatly reduced, thereby further improving the success rate of image generation.

[0053] In this embodiment, by executing the writing step of the current sub-image of the target object and the generating step of the next sub-image of the target object in parallel, the image generating speed is greatly improved compared with generating the next sub-image of the target object after completing the writing of the current sub-image. At the same time, after writing the current sub-image into the image file in the external memory, the electronic device can also release the memory space occupied by the current sub-image in the running memory, which greatly reduces the overhead of the running memory, thereby further improving the success rate of image generation.

[0054] After obtaining the current sub-image of the target object, the electronic device may encode the current sub-image and then write it into the image file of the external memory. In order to further improve the image generation speed, based on the above embodiment, optionally, Figure 2 As shown, the above S102 may include:

[0055] S201. Divide a current sub-image of the target object into a plurality of image blocks, wherein the image blocks correspond to encoders one by one.

[0056] Specifically, the electronic device may encode the current sub-image using a multi-threaded encoding method. To this end, the electronic device may divide the current sub-image into a plurality of image blocks based on the number of encoders, the number of divided image blocks being the same as the number of encoders, and different image blocks corresponding to different encoders. In the process of dividing the current sub-image, the electronic device may evenly divide the current sub-image into a plurality of image blocks, or may divide the current sub-image into a plurality of image blocks of different sizes according to a preset division rule. This embodiment does not limit the division method of the current sub-image. In addition, the encoding method adopted by the above-mentioned encoder may be Huffman coding, predictive coding, or transform coding, etc., and the corresponding encoding method may be selected according to actual needs.

[0057] S202 . Encode each image block by using an encoder corresponding to each image block to obtain a plurality of encoded image blocks.

[0058] After dividing the current sub-image into a plurality of image blocks, the electronic device uses corresponding encoders to encode each image block simultaneously, thereby obtaining a plurality of encoded image blocks.

[0059] S203 . Write each encoded image block into an image file in an external memory according to the first order of the current sub-image in the target object.

[0060] Taking the uniform division of the image as an example, the specific process of writing the current sub-image into the image file is introduced. Figure 3 , the electronic device evenly divides the current sub-image into N parts to obtain N image blocks. Wherein, N is greater than or equal to 2. Then, the electronic device uses a corresponding encoder to simultaneously encode the 1st image block, the 2nd image block...the Nth image block to obtain N encoded image blocks (the 1st encoded image block, the 1st encoded image block...the Nth encoded image block). Then, the electronic device writes each encoded image block into the image file of the external memory based on the first order of the current sub-image in the target object. Of course, the electronic device also writes the N encoded image blocks into the image file according to the order of each encoded image block in the current sub-image.

[0061] In practical applications, while encoding the current sub-image in a multi-threaded encoding manner, in order to further improve the image generation speed, the electronic device may also adjust corresponding encoding parameters to encode the image blocks divided by the current sub-image. To this end, based on the above embodiment, optionally, the above S202 may include:

[0062] S2021. Obtain encoding parameters adjusted by the user for the encoder corresponding to each image block.

[0063] Among them, the encoding speed corresponding to the adjusted encoding parameter is higher than the encoding speed corresponding to the encoding parameter before adjustment. Optionally, the encoding parameter can be the compression level of the image. In the specific implementation, a variety of image compression levels can be provided, for example, compression level 1, compression level 2... compression level 10, etc. Moreover, the higher the compression level of the image is set, the lower the encoding speed of the image, and vice versa, the lower the compression level of the image, the higher the encoding speed of the image. Based on this, in order to further improve the encoding speed of the image, thereby further improving the image generation speed, before encoding, the compression level of the image can be set to a lower level in advance. In this way, the electronic device can obtain the compression level of the image reset by the user, and encode the image block based on the compression level of the reset image. Among them, the compression level of the reset image is lower than the compression level of the image before adjustment.

[0064] S2022. Encode each image block by using each encoder and the encoding parameters adjusted by each encoder to obtain a plurality of encoded image blocks.

[0065] Among them, after obtaining the adjusted encoding parameters for each encoder, the electronic device uses each encoder and uses the adjusted encoding parameters of each encoder to encode each image block at the same time, and obtains multiple encoded image blocks. Taking the encoding parameter as the compression level as an example, it is assumed that the compression level before adjustment is 5, the compression level after adjustment is 3, and the encoding speed of the image corresponding to the compression level before adjustment is higher than that of the image corresponding to the compression level before adjustment. After obtaining the adjusted compression levels of each encoder, the electronic device uses a relatively low compression level to encode each image block of the current sub-image at the same time, obtains multiple encoded image blocks, and writes each encoded image block into the image file based on the order of each encoded image block in the current sub-image, thereby completing the writing process of the current sub-image.

[0066] In this embodiment, the electronic device can encode the current sub-image using a multi-threaded encoding method, thereby increasing the encoding speed of the image, thereby increasing the image generation speed. In addition, the electronic device can also encode the image block of the current sub-image using a relatively low encoding parameter, thereby further increasing the image encoding speed, thereby further increasing the image generation speed.

[0067] In one embodiment, in order to improve the accuracy of the target image, an abnormality detection mechanism is also provided. Based on the above embodiment, optionally, Figure 4 As shown, before writing the current sub-image into the image file in the external memory, the method may further include:

[0068] S401: Perform anomaly detection on the current sub-image.

[0069] Among them, the electronic device can use image rendering to obtain a sub-image sequence of the image to be generated. In this way, due to some problems in the image rendering method itself, some abnormalities may occur in the obtained sub-image sequence. For example, the obtained sub-image may have a large area of ​​white screen, black screen or blur. Therefore, after obtaining the current sub-image, the electronic device needs to perform an abnormality detection on the current sub-image to detect whether the current sub-image has abnormalities such as white screen, black screen or blur.

[0070] S402: When it is determined that the current sub-image is an abnormal image, regenerate the current sub-image according to a preset retry mechanism.

[0071] Among them, when it is determined that the current sub-image is an abnormal image, the electronic device can regenerate the current sub-image. For example, re-read the content corresponding to the abnormal image in the file, and re-render the content into the corresponding image to obtain a new current sub-image. In a specific implementation, the retry frequency of the sub-image can be set, such as the retry frequency can be controlled by monitoring the system frame callback, and the electronic device re-acquires the current sub-image based on the retry frequency. Of course, when it is determined that the current sub-image is a normal image, that is, there is no abnormal situation such as a white screen, a black screen, and blur in the current sub-image, the electronic device directly writes the current sub-image into the image file according to the order of the current sub-image in the target object.

[0072] In order to facilitate those skilled in the art to understand the abnormality detection process, Figure 5 The process shown is taken as an example to introduce Figure 5 Specifically, the anomaly detection process may include:

[0073] S501: Generate a current sub-image of a target object.

[0074] S502: Detect whether the current sub-image has abnormal conditions such as white screen, black screen, blur, etc.

[0075] If it exists, execute S503; if it does not exist, after encoding the current sub-image, write the current sub-image into the image file according to the first order of the current sub-image in the target object.

[0076] S503: Wait for the system frame callback to regenerate the current sub-image.

[0077] Optionally, in order to avoid endless retries, a retry end condition may be set. Based on the above embodiment, optionally, the process of writing the current sub-image into the image file in the external storage device according to the first order of the current sub-image in the target object may be: when the number of times the current sub-image is generated reaches a preset threshold, and the newly generated current sub-image is still an abnormal image, the new current sub-image is written into the image file in the external storage device according to the first order.

[0078] Among them, when the number of retries exceeds the preset threshold, that is, when the number of acquisitions of the current sub-image reaches the preset threshold, if the newly generated current sub-image still has abnormal conditions such as white screen, black screen or blur, the new current sub-image can be directly encoded and written into the image file of the external storage device according to the first order.

[0079] Of course, for other sub-images of the target object, such as the next sub-image, the electronic device's abnormality detection process for other sub-images can refer to the above-mentioned abnormality detection process for the current sub-image, and this embodiment will not be repeated here.

[0080] In this embodiment, the electronic device can perform anomaly detection on the acquired sub-image of the target object, and regenerate the corresponding sub-image when anomalies exist in the sub-image to ensure the accuracy of the sub-image sequence, thereby improving the accuracy of the final target image.

[0081] Figure 6 A schematic diagram of the structure of an image generating device provided by an embodiment of the present invention. Figure 6 As shown, the device may include: a first generating module 601 and a first writing module 602.

[0082] Specifically, the first generating module 601 is used to sequentially generate sub-images of the target object;

[0083] The first writing module 602 is used to write the sub-images into the image file of the external memory in sequence according to the order of the sub-images in the target object, so as to obtain the target image corresponding to the target object.

[0084] The image generation device provided by the embodiment of the present invention sequentially generates each sub-image of the target object, and sequentially writes each sub-image into the image file of the external memory according to the order of each sub-image in the target object, so as to obtain the target image corresponding to the target object. That is to say, after each sub-image is obtained, the electronic device will directly write the sub-image into the image file of the external memory according to the order of the sub-image in the target object, so as to automatically complete the splicing of each sub-image of the target object in the external memory. Compared with the traditional method of needing to complete the splicing of all sub-images in the running memory and then write them into the disk memory, the running memory overhead is greatly reduced, thereby improving the success rate of image generation.

[0085] On the basis of the above embodiment, optionally, the first writing module 602 is specifically used to write the current sub-image of the target object into the image file of the external storage device according to the first order of the current sub-image of the target object in the target object, and generate the next sub-image of the target object at the same time; obtain the second order of the next sub-image in the target object, and write the next sub-image into the image file according to the second order until the last sub-image of the target object is written into the image file, so as to obtain the target image of the target object.
