[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] In one embodiment, in the current process of mobile phone photography, after clicking the camera button, the application (Application, APP) determines whether the mobile phone memory is sufficient at this time. If sufficient, it immediately sends the frame data and corresponding parameters required for this photo shooting, obtains them from the camera hardware abstraction layer, and sends them to the asynchronous partial synchronization (Asynchronous Partial Synchronous, APS) algorithm processing module to process the image. After the processing is completed, it returns to the APP to be sent to the album for display; if the mobile phone memory is insufficient at this time, the photo shooting event will not be responded to. Figure 1 As shown in the steps:

[0035] Step 101, receiving a command to start taking photos.

[0036] Here, the user may click to take a photo.

[0037] Step 102, determining whether the mobile phone memory is sufficient at this time.

[0038] Here, if the mobile phone memory is sufficient, go to step 103, if the mobile phone memory is insufficient, go to step 107.

[0039] Step 103, capturing the required image through the mobile phone camera.

[0040] Step 104: Send and execute a real-time photography task (RTJob).

[0041] Step 105, entering the APS algorithm processing module to perform algorithm post-processing on the original image data.

[0042] Step 106, after the original image data is processed, the obtained image is returned to the APP, so that the APP sends the image to the album for display.

[0043] Step 107, discard the photo taking event.

[0044] During the photo shooting process, the phone processes the photo data, which requires a certain amount of mobile phone memory space to store the original data, the intermediate data during the processing, and the final large image return data. If there is not enough memory space, it will cause memory stampede or task execution failure, so the photo event is discarded when the memory is insufficient.

[0045] exist Figure 1 In the process required for taking photos, the APS algorithm processing module takes the longest time. The APS algorithm processing module needs to call the central processing unit (CPU), graphics processing unit (GPU), neural network processor (NPU), camera image processor (ISP) and other hardware resources to perform multiple operations such as data frame fusion and denoising. The photo is not finished until all algorithms are processed. The normal effect algorithm processing takes about 1 to 2 seconds, so there will inevitably be memory accumulation in the quick shooting scene. Figure 2 As shown, in the first photo 21, the first photo 22, the first photo 23 and the fourth photo 24, each photo has three stages. Taking the first photo as an example, the photo process includes: start capture, add frame and algorithm processing (algo process); among them, the startCapture stage and the add Frame stage take a total of 500 milliseconds (ms), and the algo Process stage takes 2000ms. It can be seen that in the entire process of taking pictures, the algorithm processing in the APS algorithm processing module takes the longest time, which requires 2000ms. In this way, memory accumulation is prone to occur in the quick shot scene.

[0046] In order to solve the problem of snapshot accumulation in memory, the related technology switches the algorithm to a lightweight algorithm to process, sacrificing the final imaging effect to avoid memory accumulation, such as Figure 3 As shown in the steps:

[0047] Step 301, receiving a command to start taking photos.

[0048] Step 302, determining whether the number of accumulated photographs in the memory is greater than N times.

[0049] Here, if the number of accumulated photographs in the memory is greater than N times, go to step 303; if the number of accumulated photographs in the memory is less than N times, go to step 304.

[0050] Step 303: Select an algorithm with poor imaging effect but short time consumption.

[0051] Step 304, select an algorithm that has good imaging effect but takes a long time.

[0052] Step 305, collecting frame data required by this photo-taking algorithm.

[0053] Step 306: Send the original image data that meets the frame data to the APS algorithm processing module for algorithm processing.

[0054] Step 307, after processing the original image data, the image is sent back to the APP, so that the APP sends the image to the album for display.

[0055] In this photo-taking process, when the phone is low on memory, the photo-taking event will be discarded. This means that when the phone's background application or the phone's camera occupies the memory for any reason, the phone's camera will be unable to respond to the photo-taking event, which provides a poor user experience. In addition, in order to reduce memory accumulation in quick-shot scenarios, related technologies sacrifice imaging effects.

[0056] Based on this, the embodiment of the present application provides an image processing method, which first determines the memory of the image processing terminal after obtaining the photo instruction, and saves the original image data corresponding to the photo instruction when it is determined that the memory does not meet the preset conditions; in this way, after determining that the memory of the image processing terminal does not meet the preset conditions, the original image data is saved in the image processing terminal, which can facilitate the subsequent call of the original image data to execute the task under the photo instruction. In this way, when the mobile phone memory is insufficient, the obtained original image data is saved, and when the mobile phone memory is sufficient, the algorithm processing of the photo task is performed, thereby solving the problem that the mobile phone camera cannot take pictures under low memory.

[0057] The image processing method provided in the embodiment of the present application can be applied to Figure 4 In the application environment shown. Among them, the image processing terminal 401 may include a display module and a collection module. After receiving a photo-taking instruction or, first determine whether the memory meets the preset conditions; if the memory does not meet the preset conditions, then the original image data of the current scene is collected by the collection module and saved in the disk of the image processing terminal 104; when it is detected that the memory meets the preset conditions, the saved original image data is read from the disk, so that the original image data is processed to obtain the target image and displayed on the display module. Among them, the image processing terminal 401 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0058] In one embodiment, Figure 5 As shown, an image processing method is provided, which is applied to Figure 5 The image processing terminal in the example is used as an example to illustrate, including the following steps:

[0059] Step 501, in response to the acquired photographing instruction, if it is determined that the memory of the image processing terminal does not meet the preset condition, save the original image data corresponding to the photographing instruction.

[0060] The photo command may be a quick shot command or a non-quick shot command, such as a regular photo command or a slow shot command. The photo command may be input by the user by clicking a photo button, or by voice, or by remote control. The image processing terminal corresponding to the photo command may be a terminal to which the application receiving the photo command belongs, or a terminal receiving the photo command. For example, a mobile phone, computer, drone, or camera device with a photo application installed.

[0061] The original image data matched by the photographing instruction is the unprocessed image data acquired by the image processing terminal, and the original image data may be the image data volume and image parameters required to satisfy the photographing instruction.

[0062] Exemplarily, if the photo taking instruction is a non-snapshot instruction, the original image data is data satisfying the image parameters of the non-snapshot instruction, for example, the image parameters may include the original (ROW) image format, image size, image background, image watermark, etc. If the photo taking instruction is a snapshot instruction, the original image data is original image data satisfying the required number of image frames under the snapshot instruction.

[0063] The preset condition is used to determine the memory occupancy of the image processing terminal, and can be set according to the memory space or data processing capacity of the image processing terminal, or can be user-defined. If the memory of the image processing terminal does not meet the preset condition, it means that the memory occupancy rate of the image processing terminal is high, and the current memory is insufficient to immediately execute the photo command; if the memory of the image processing terminal meets the preset condition, it means that the memory occupancy rate of the image processing terminal is low, and the current memory is sufficient to immediately execute the photo command; in this way, when the memory does not meet the preset condition, saving the original image data corresponding to the photo command can facilitate the subsequent calling of the original image data when the memory meets the preset condition to actively respond to the photo command.

[0064] In some possible implementations, after obtaining the photographing instruction, the original image data matching the photographing instruction is obtained. At the same time, it is determined whether the memory of the image processing terminal meets the preset conditions. If the memory of the image processing terminal does not meet the preset conditions, the original image data is saved.

[0065] Step 502: When it is detected that the memory of the image processing terminal meets the preset condition, the stored original image data is processed to obtain the target image of the photographing instruction.

[0066] The fact that the memory satisfies the preset condition indicates that the memory of the image processing terminal is not occupied at the current moment and can be used for image processing. The target image of the photo command, that is, the image output to the album, is displayed on the display interface of the image processing terminal for easy viewing by the user.

[0067] In some possible implementations, after the original image is saved, the memory information of the image processing terminal is detected. For example, the memory information of the image processing terminal may be detected at certain time intervals, or the memory information of the image processing terminal may be detected continuously. Until it is detected that the memory information of the image processing terminal meets the preset conditions, the saved original image data is read, and the original image data is processed using the image processing algorithm required by the photo instruction to obtain the target image, thereby completing the photo task of the photo instruction. For example, the original image data is subjected to filter processing, image format conversion processing, noise reduction processing, etc., to obtain the target image that can be presented to the user.

[0068] In an embodiment of the present application, after obtaining a photographing instruction, the memory of the image processing terminal corresponding to the photographing instruction is first determined, and when it is determined that the memory of the image processing terminal does not meet the preset conditions, the original image data corresponding to the photographing instruction is saved; in this way, the original image data can be easily called later to execute the task under the photographing instruction. When it is detected that the memory of the image processing terminal meets the preset conditions, the saved original image data is processed to obtain the target image of the photographing instruction. In this way, the original image data obtained under this photographing instruction is saved when the memory does not meet the preset conditions, and the saved original image data is read until the memory of the image processing terminal meets the preset conditions, so that the original image data can be effectively processed in the memory that meets the preset conditions, so as to complete the task under the photographing instruction with high accuracy, and then provide the target image that meets the photographing instruction.

[0069] In some possible implementations, before step 501, in order to accurately analyze whether the memory meets the preset conditions, it also includes Figure 6 Steps shown:

[0070] Step 601, in response to the photographing instruction, determining the memory information of the image processing terminal.

[0071] The memory information of the image processing terminal is used to characterize the occupancy of the disk in the image processing terminal; optionally, the memory information may be the remaining amount of memory space or the number of snapshots accumulated in the memory. The determined memory information is different for different types of photo instructions. For example, if the photo instruction is a non-snapshot instruction, the memory information is the remaining amount of memory space in the image processing terminal; if the photo instruction is a snapshot instruction, the current internal information is the number of photos accumulated in the memory of the image processing terminal. The user inputs the photo instruction by clicking on the photo instruction. After receiving the photo instruction, the disk of the image processing terminal is accessed to obtain the memory information of the disk.

[0072] Step 602: Determine whether the memory of the image processing terminal meets the preset condition according to the memory information.

[0073] The preset condition varies with different memory information. For example, if the memory information is the remaining amount of memory space, the preset condition is the preset memory threshold; if the memory information is the number of times of accumulated photos, the preset condition is the preset number threshold. If the remaining amount of memory space is less than the preset memory threshold, or the number of accumulated photos is greater than the preset number threshold, it means that the current memory occupancy rate of the image processing terminal is high, that is, the memory information does not meet the preset condition.

[0074] In some possible implementations, if the memory information does not meet the preset conditions, it means that the disk occupancy rate in the image processing terminal is high and it is not suitable to immediately complete the photo task of the photo instruction. At this time, the acquired original image data is saved, which can facilitate reading the original image data when the memory information of the image processing terminal meets the preset conditions in the future, thereby completing the photo task of the photo instruction with high quality.

[0075] After receiving the photo command, it is determined whether the memory information meets the preset conditions. If the memory information meets the preset conditions, it means that the memory occupancy rate of the image processing terminal is not high at the current moment, and the original image data can be directly obtained, and the target image processing algorithm corresponding to the photo command is used to process the original image data to obtain the target image. In this way, when it is determined that the memory information meets the preset conditions, the photo command is responded to immediately, so that the photo task under the photo command can be completed quickly and with high quality to obtain the target image that meets the user's needs.

[0076] In one embodiment, when the photo taking instruction is not a quick shot instruction and the memory information includes the remaining memory space of the image processing terminal, the remaining memory space of the image processing terminal is analyzed to accurately determine whether the memory meets the preset condition, that is, the above step 602 may include the following two situations:

[0077] In case 1, when the remaining amount of the memory space is less than the preset memory threshold, it is determined that the memory of the image processing terminal does not meet the preset condition.

[0078] Among them, after obtaining the photo taking instruction, the disk used to store image data in the image processing terminal is first detected; and then the remaining memory space in the disk is determined. The preset memory threshold can be set according to the total storage space of the image processing terminal and the data processing speed of the terminal. For example, if the data processing speed is relatively high, the preset memory threshold can be appropriately set to be relatively small. The preset storage threshold can represent the size of the storage space, and can also be the ratio of the remaining memory space to the total storage space; if the total storage space is relatively large, then the ratio as the preset memory threshold can be set to be relatively small.

[0079] In case 2, when the remaining amount of the memory space is greater than or equal to the preset memory threshold, it is determined that the memory of the image processing terminal meets the preset condition.

[0080] Among them, if the remaining amount of memory space is greater than or equal to the preset memory threshold, it means that the image processing terminal has sufficient memory space to respond to the photo command, and can quickly and high-quality execute the photo task under the photo command. In this way, by judging whether the remaining amount of memory space of the image processing terminal is less than the preset memory threshold, it is possible to more accurately analyze whether the remaining amount of memory space of the image processing terminal is sufficient. Moreover, in the embodiment of the present application, if the remaining amount of memory space of the image processing terminal is insufficient, the original image data is first saved in the preset disk, and there is no need to discard the photo task of the photo command; when the remaining amount of memory space is sufficient, the original image data is read again, so that the photo task under the photo command can be completed with higher quality.

[0081] In some possible implementations, in order to make the original image data satisfy the photographing task under the photographing instruction, the acquired original image data may be saved through the following process:

[0082] First, in response to the acquired photographing instruction, when it is determined that the memory of the image processing terminal does not meet the preset conditions, the image parameters matching the photographing instruction are determined.

[0083] The image parameters matched by the photo taking instruction include one or more of the following: the image format (eg, RAW format or YUV format), the image size, the image background, and whether there is a watermark in the image.

[0084] In some possible implementations, when a photographing instruction is obtained, the image parameters required to complete the photographing instruction can be obtained by parsing the photographing instruction.

[0085] Then, in the picture corresponding to the photographing instruction, the original image data satisfying the image parameters is acquired and saved.

[0086] The picture corresponding to the photographing instruction is the picture within the acquisition range of the camera in the image processing terminal in response to the photographing instruction, such as the preview picture that can be seen through the camera. In the picture corresponding to the photographing instruction, data is collected for the picture according to the image parameters to obtain and save the original image data; for example, the original image data is saved in a preset disk of the image processing terminal. In this way, according to the image parameters matched by the photographing instruction, the data in the current scene is collected, so that the obtained original image data can meet the photographing task under the photographing instruction. Saving such original image data can facilitate the subsequent algorithm post-processing of the original image data to obtain the target image that meets the photographing task.

[0087] In one embodiment, in order to complete the photographing task under the photographing instruction with high quality and obtain the target image with good display imaging effect, the above step 502 can be implemented by the following process:

[0088] S1, detecting the remaining amount of memory space of the image processing terminal.

[0089] The remaining amount of memory space of the image processing terminal may be detected at a first preset time interval. The first preset time interval may be set according to the processing time required for the image processing terminal to successfully complete a photo task under a photo instruction, for example, the first preset time interval is set to be greater than or equal to 0 and less than the processing time; the first preset time interval may also be user-defined.

[0090] Exemplarily, if the first preset time interval is 0, the remaining memory space of the image processing terminal is continuously checked; or, if the first preset time interval is greater than 0, the remaining memory space of the image processing terminal is periodically checked according to the first preset time interval.

[0091] S2, when it is detected that the remaining amount of memory space is greater than or equal to the preset memory threshold, processing the saved original image data to obtain the target image.

[0092] Here, if it is detected that the remaining amount of memory space is greater than or equal to the preset memory threshold, it means that at the current moment, the remaining amount of memory space of the image processing terminal is large, that is, there is enough memory space to perform algorithm post-processing on the saved original image data to obtain the target image that can be output to the album for the user to view. In this way, by detecting in real time whether the remaining amount of memory space of the image processing terminal is sufficient, the saved original image data is processed until it is detected that the remaining amount of memory space is sufficient, so that the photo-taking task can be completed with high accuracy without affecting the imaging effect of the output target image.

[0093] In some possible implementations, when the memory information is the remaining amount of memory space, in order to complete the photographing task under the photographing instruction in sufficient memory space to obtain a target image with good image quality, the above step 502 may be implemented by the following process:

[0094] First, when it is detected that the remaining amount of memory space is greater than or equal to the preset memory threshold, the original image data is read from a preset disk of the image processing terminal.

[0095] The preset disk is used to store the original image data. In the process of real-time detection of the remaining memory space of the image processing terminal, if it is detected that the remaining memory space is greater than or equal to the preset memory threshold, it means that the memory space of the image processing terminal is sufficient for image processing at the current moment, and then the saved original image data is read from the preset disk.

[0096] Then, the original image data is post-processed using a target image processing algorithm matched with the photographing instruction to obtain the target image.

[0097] Among them, the target image processing algorithm required for the photo command includes one or more of the following algorithms: image conversion algorithm, filtering algorithm, noise reduction algorithm, beauty processing algorithm, filter processing algorithm, watermark processing algorithm, blur processing algorithm, High Dynamic Range Imaging (HDR) processing algorithm and multi-frame processing algorithm. After reading the original image data from the preset disk, enter the APS algorithm processing module, call the target image processing algorithm in the APS algorithm processing module, post-process the original image data, obtain the target image, and return the target image to the application that receives the photo command to send it to the terminal album, so as to present it to the user. In this way, when it is detected that there is sufficient remaining memory space, the original image data is read and the original image data is post-processed by the algorithm, so that the target image that meets the photo command can be obtained efficiently and with high quality.

[0098] In one embodiment, when the photographing instruction is a quick-take instruction and the memory information includes the number of accumulated photographing times in the memory of the image processing terminal, the number of accumulated photographing times in the memory of the image processing terminal is analyzed to accurately determine whether the memory meets the preset condition, that is, the above step 602 includes the following two situations:

[0099] In case 1, when the number of photo accumulation times is greater than a preset number threshold, it is determined that the memory of the image processing terminal does not meet the preset condition.

[0100] Among them, the preset number threshold can be set according to the total storage space of the image processing terminal and the data processing speed of the terminal. For example, if the data processing speed is relatively high, the preset number threshold can be appropriately set to be relatively high; if the data processing speed is relatively low, the preset number threshold can be appropriately set to be relatively low. If the number of accumulated photos is greater than the preset number threshold, it means that the number of photos accumulated in the memory of the image processing terminal is relatively large, so that it is not possible to continue to respond immediately to the input photo command. Therefore, in the embodiment of the present application, the acquired original image data is temporarily stored in the preset disk of the image processing terminal, and the image processing is performed when the number of accumulated photos in the memory is relatively small.

[0101] In some possible implementations, after obtaining a photographing instruction, first detect a disk in the image processing terminal for storing image data; then determine the number of photograph accumulations in the disk, thereby determining whether the number of photograph accumulations is greater than a preset threshold.

[0102] In case 2, when the photo accumulation times are less than or equal to the preset times threshold, it is determined that the memory of the image processing terminal meets the preset conditions.

[0103] Among them, if the number of accumulated photographs is less than or equal to the preset number threshold, it means that the number of accumulated photographs in the memory of the image processing terminal is small, and the input photographing command can be responded to immediately. In this way, by judging whether the number of accumulated photographs in the memory of the image processing terminal is greater than the preset number threshold, it is determined whether the number of accumulated photographs in the image processing terminal is too many, so that it is possible to accurately judge whether the memory information meets the preset conditions. Moreover, in the embodiment of the present application, if the number of accumulated photographs in the image processing terminal is too many, then in order to successfully complete each photographing command, the original image data under this photographing command is first saved in the preset disk; after the number of accumulated photographs decreases, the original image data under this photographing command is read from the preset disk, so that the original image data can be processed with a better salient processing algorithm to obtain a target image with a higher imaging effect.

[0104] In some possible implementations, when the memory information includes the number of times of photographing in the memory of the image processing terminal, in order to make the original image data satisfy the target image processing algorithm with better imaging effect, the above step 501 can be performed by Figure 7 The steps shown are to obtain and save the raw image data:

[0105] Step 701, in response to the acquired photographing instruction, when it is determined that the memory of the image processing terminal does not meet the preset condition, determine a target image processing algorithm that matches the photographing instruction in a preset image processing algorithm set.

[0106] The preset image algorithm set includes: multiple types of algorithms for imaging, each algorithm has different imaging quality, such as multiple image noise reduction methods with different image quality, multiple image filter algorithms with different image quality, multiple watermark processing algorithms with different image quality, etc. For example, in the preset image processing algorithm set, for each image processing algorithm, a target image processing algorithm with the highest imaging quality is selected; in this way, by processing the original image data through the target image processing algorithm, the imaging effect of the obtained target image can be better.

[0107] Step 702: Determine the frame data required by the target image processing algorithm.

[0108] The frame data required by the target image processing algorithm includes: the number of image frames and image parameters required when the target image processing algorithm performs image processing, etc. The image parameters may include: image format, image size, whether there is a watermark or image background light.

[0109] Step 703, in the current picture where the photo taking instruction is located, the original image data satisfying the frame data is obtained and saved.

[0110] Among them, according to the number of image frames and the required image parameters when the target image processing algorithm is used for image processing, data is collected in the picture where the photo instruction is located to obtain the original image data that meets the number of image frames and image parameters. For example, the number of image frames is 5 frames, and the image parameters include: image format and image size, then in the current picture, 5 frames of original image data that meet the image format and image size are collected. In this way, by selecting a target image processing algorithm with better imaging effect, the original image data that meets the frame data required by the algorithm is collected, so that when the number of photo stacking is small, the original image data read can be processed by the target image processing algorithm to improve the image quality of the target image and obtain an image that can meet the user's needs.

[0111] In one embodiment, when the memory information is the number of accumulated photographing times, in order to respond to the current photographing instruction without reducing the imaging effect of the target image, the above step 502 can be implemented by the following process:

[0112] S1, detecting the number of accumulated photographs in the memory of the image processing terminal.

[0113] The number of accumulated photographing times in the memory of the image processing terminal may be detected according to a second preset time interval. The second preset time interval may be the same as or different from the first preset time interval. The second preset time interval may be set according to the processing time required for the image processing terminal to successfully complete a photographing task under a quick-shooting instruction, or may be set independently by the user.

[0114] Exemplarily, if the second preset time interval is 0, the number of accumulated photos taken by the image processing terminal is continuously detected; or, if the second preset time interval is greater than 0, the number of accumulated photos taken by the image processing terminal is detected once every second preset time interval.

[0115] S2, when it is detected that the number of photographing accumulation times is less than or equal to the preset number threshold, the saved original image data is post-processed using the target image processing algorithm matched with the photographing instruction to obtain the target image of the photographing instruction.

[0116] Here, if it is detected that the number of accumulated photographs is less than or equal to the preset number threshold, it means that at the current moment, the number of accumulated photographs in the image processing terminal is small, that is, the terminal has sufficient computing power to perform algorithm post-processing on the saved original image data to obtain the target image. In this way, after it is detected that the number of accumulated photographs is reduced, the original image data is read from the preset disk to process the original image data using the determined target image algorithm. Since the target image algorithm is a selected algorithm with higher imaging quality, the imaging effect of the target image is better.

[0117] In one embodiment, in order to further complete the photographing task under the photographing instruction with high quality to obtain a target image that meets the user's needs, the above step 502 can be implemented by the steps shown in Figure 8:

[0118] Step 801, when the photo accumulation times are less than or equal to the preset times threshold, detecting the remaining amount of memory space of the image processing terminal.

[0119] When it is detected that the number of accumulated photographing times is greater than a preset number threshold, the remaining amount of memory space of the image processing terminal is further detected to determine whether the remaining amount of memory space of the image processing terminal is sufficient.

[0120] Step 802, when the remaining amount of the memory space is greater than or equal to a preset memory threshold, the saved original image data is processed to obtain a target image of the photographing instruction.

[0121] If the remaining amount of memory space is greater than or equal to the preset memory threshold, that is, the remaining amount of memory space is sufficient, then continue to detect whether the number of times of photo accumulation decreases by less than or equal to the preset number threshold. If the remaining amount of memory space is less than the preset memory threshold, then continue to detect the remaining amount of memory space until the remaining amount of memory space is sufficient, and then detect the number of photo accumulation. In this way, when the remaining amount of memory space is sufficient and the number of photo accumulation is small, the original image data is read from the preset disk, and the target image processing algorithm is used to process the original image data to obtain the target image.

[0122] In an embodiment of the present application, when the memory information includes the number of accumulated photographs in the memory of the image processing terminal, if the number of accumulated photographs is large, then it is continued to determine whether the remaining memory space of the image processing terminal is sufficient; if the remaining memory space is sufficient, then it is continued to detect whether the number of accumulated photographs is less than or equal to a preset number threshold, and only when the remaining memory space is sufficient and the number of accumulated photographs is small, the original image data is read to process the original image data using a target processing algorithm to obtain a target image; in this way, by performing multi-level analysis on the memory status of the image processing terminal, there can be sufficient memory space to process the original image data to complete the photographing task under the photographing instruction, and the picture quality of the target image can also be improved.

[0123] In other embodiments, after detecting that the number of photo accumulation times is greater than a preset number threshold, continue to detect whether the number of photo accumulation times has decreased; until it is detected that the number of photo accumulation times is less than the preset number threshold, then detect the remaining memory space of the image processing terminal until the remaining memory space is greater than the preset memory threshold, and read the original image data from the preset disk.

[0124] In the quick-shot scenario, when the number of accumulated photo tasks reaches a certain threshold, the photo task goes through the deferJob processing flow. When the camera is exited or the accumulated photo tasks in the memory drop to a certain value, the photo task algorithm is processed. This reduces the problem of poor imaging effects caused by the phone switching to a lightweight algorithm after taking multiple photos.

[0125] In some possible implementations, the process of processing the photographed data is as follows: Fig. 9 As shown in the steps:

[0126] Step 901, receiving a command to start taking photos.

[0127] Step 902, determining whether the current mobile phone memory is sufficient.

[0128] Here, if the current mobile phone memory is sufficient, go to step 903; if the current mobile phone memory is insufficient, go to step 911.

[0129] Step 903, using the mobile phone camera to capture the required image.

[0130] Step 904: Send and execute the RTJob instruction.

[0131] Step 905, enter the APS algorithm processing module to perform algorithm post-processing on the image data. After the algorithm processing is completed, the image is returned to the APP to be sent to the album for display.

[0132] Here, after completing step 905, you can return to step 901.

[0133] Step 911, using the mobile phone camera to capture the required image.

[0134] Step 912: Send and execute the deferJob instruction.

[0135] Step 913, storing the collected image data in the mobile phone disk.

[0136] Step 914, when the mobile phone memory is sufficient, read the image data from the disk and send it to the APS algorithm processing module.

[0137] Step 915, perform algorithm post-processing on the image data.

[0138] Step 916, after the algorithm is processed, the image is returned to the APP to be sent to the album for display.

[0139] Here, after completing step 916, the process may return to step 901.

[0140] In an embodiment of the present application, by adding an operation of storing the deferJob photo task on disk during the image data flow process, after clicking to query the memory status, the photo data is obtained, and it is determined whether to enter the RTJob process or the deferJob process according to the mobile phone's memory status. If there is sufficient memory, the RTJob process can be entered for image processing; if it is already in a low memory condition at this time, the deferJob process is entered for image processing, and all the data of this photo task is stored on disk. When the mobile phone exits the camera (which will release a large block of memory) or when enough memory is released for other reasons, the photo data is read from the disk for algorithm processing. After the algorithm processing is completed, the processed image can be sent to the album for storage.

[0141] In the snapshot scenario, the image data can be processed by Fig.10The steps shown achieve:

[0142] Step 1001, receiving a command to start taking photos.

[0143] Step 1002, determining whether the number of accumulated photos in the memory is greater than N times.

[0144] Here, if the number of accumulated photographs in the memory is greater than N times, go to step 1003; if the number of accumulated photographs in the memory is less than N times, go to step 1011.

[0145] Step 1003, select an algorithm that has good imaging effect but takes a long time.

[0146] Step 1004, collecting frame data required by this photo-taking algorithm.

[0147] Step 1005, enter the deferJob process, and store the original image data that meets the frame data into the disk.

[0148] Step 1006, when the APP determines that the number of accumulated photos in the memory is 0, the deferJob process is executed.

[0149] Step 1007, obtaining original image data from the disk.

[0150] Step 1008: Send the original image data to the APS algorithm processing module for algorithm processing.

[0151] Step 1009, after the algorithm processing is completed, the image is returned to the APP to be sent to the album for display.

[0152] After completing step 1009 , the process may return to step 1006 .

[0153] Step 1011, select an algorithm that has good imaging effect but takes a long time.

[0154] Step 1012, collecting frame data required by this photo-taking algorithm.

[0155] Step 1013, sending the original image data that meets the frame data to the APS algorithm processing module for algorithm processing.

[0156] Step 1014, after the algorithm processing is completed, the image is returned to the APP to be sent to the album for display.

[0157] After completing step 1014 , the process may return to step 1001 .

[0158] In the above Fig.10In the quick shot scenario, add the operation of storing the deferJob photo task on disk. After clicking on the photo to obtain the photo data, determine whether to enter the RTJob process or the deferJob process based on the accumulation of photo times in the phone's memory. If the accumulation of photo times does not reach the set threshold, the RTJob process can be entered to process the image; if the accumulation of photo times has reached the threshold at this time, the deferJob process can be entered to process the image and store all the photo task data on disk. When the phone exits the camera (no new photo tasks will be added at this time) or the accumulation of photo times drops below the set threshold (because the algorithm post-processing is always executing tasks), read the photo data from the disk for algorithm processing. When the algorithm processing is completed, send the processed image to the album for storage.

[0159] In an embodiment of the present application, the photo task is switched according to the memory status when taking pictures or the number of photos accumulated in the memory; wherein, the reasons for task switching include but are not limited to memory, performance, power consumption, hardware resource conflicts and all other aspects that affect the user's photo experience and imaging effect. When the memory is sufficient, the RTJob task process is executed, and when the memory is insufficient, the deferJob task process is executed. When the number of accumulated photos is low, the RTJob task process is executed, and when the number of accumulated photos is high, the deferJob task process is executed. In this way, the problem of having to switch to a lightweight algorithm due to the accumulation of photos, resulting in poor imaging effect of the mobile phone, can be solved. It can also solve the problem that the mobile phone needs to have sufficient memory for taking pictures, and when the memory is insufficient, it does not respond to the photo event, so that the mobile phone cannot take pictures.
