Description

Technical Field

[0001] The present disclosure relates to the field of data processing technology, and in particular to a data processing method, an image data processing method, an apparatus, a device, and a medium. Background Art

[0002] Data processing is essential in electronic devices. In order to better use data to represent some information, the maximum data bit of the data is usually fixed. However, for some data, the maximum data bit may no longer be able to accurately represent the corresponding information. For example, for image data, the maximum data bit of the image data is 10 bits, but the actual information to be represented may be 12 bits. In this case, 10 bits of data cannot be used to represent the information of 12 bits of data.

[0003] In related technologies, in order to better represent the corresponding information, when the data bits are insufficient, the data bits are increased. However, increasing the data bits will use more memory. Moreover, when transmitting data, the large amount of data will increase the power consumption of the transmission and reduce the transmission rate, thereby reducing the performance of the device.

[0143] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0144] The data processing method provided by the embodiments of the present disclosure can be applied to various scenarios, such as image data processing scenarios, video data processing scenarios, and the like.

[0145] Taking image data processing as an example, in related technologies, during the imaging process, the image sensor first captures a raw image (image data). After a series of image processing operations on the raw image, a de-mosaicing algorithm is used to convert the raw image into an RGB image. After the RGB image is processed, it is converted into a YUV image for further image processing. During this series of image processing, the data bit size of the image data in RAW and YUV formats affects the accuracy of image processing. Images with larger data bits have higher image accuracy and better image quality, but this also brings problems: increased memory consumption and data transmission power consumption, resulting in reduced performance. Therefore, a trade-off is usually made between image quality, performance, power consumption, and memory.

[0146] In one example, the raw image captured by an image sensor has 10 bits of data. Because image processing operations such as pixel correction, black level correction, lens shading correction, and white balance correction are performed on the raw image, the data bits of the raw image need to be increased from 10 to 16 or 18 bits. This, on the one hand, prevents data overflow during the processing of these algorithms, and on the other hand, improves data precision and image processing quality. However, increasing the data bits to improve image processing precision not only increases the storage space of the raw image and increases memory usage, but also increases power consumption and reduces the transmission rate during the transfer of each image processing algorithm to the next, resulting in a decrease in device performance.

[0147] The data processing method and image data processing method provided by the embodiments of the present disclosure propose a data encoding and decoding function. The data is first encoded, and the data with larger data bits is saved into the data with smaller data bits. Then, the encoded data is decoded to obtain the original data. While ensuring the complete preservation of the data, the use of memory is reduced. During data transmission, the transmission rate can be increased, and the performance of the device can be improved. In addition, for image data, since the data is completely preserved, high-precision image data can be saved, which increases the accuracy of image processing and improves image quality.

[0148] In one example, using the long-exposure image, normal-exposure image, and short-exposure image in HDR (High Dynamic Range) technology as examples, in the long-exposure case, the overall brightness of the exposed image is brighter, the image data is larger, and data overflow is very easy. In the normal-exposure case, the overall brightness of the exposed image is relatively normal, but the image data in the highlights is also larger, making data overflow easy. In the short-exposure case, the overall brightness of the exposed image is darker, and the image data is smaller. Based on the above characteristics of exposed images with different exposure levels, combined with the limited data bits for image data storage (for example, the maximum data bits of image data are 10 bits, and the pixel parameter of each pixel is up to 1023. If it exceeds 1023, it will overflow. For example, if the pixel parameter is 1260, the pixel parameter will be truncated to 1023), and the smaller image data of the short-exposure image, the image data of the short-exposure image can be fully utilized to store the overflowed data bits in the image data of the long-exposure and normal-exposure images.

[0149] The method provided in the embodiments of the present disclosure is executed by an electronic device, which may be a mobile phone, tablet computer, laptop computer, wearable device, smart home device, or the like.

[0150] The data processing method provided by the embodiment of the present disclosure includes a data encoding process and a data decoding process. Figure 1 and Figure 2 The embodiment shown illustrates the encoding process by Figure 3 and Figure 4 The illustrated embodiment illustrates the decoding process.

[0151] Figure 1 is a flow chart showing a data processing method according to an exemplary embodiment, which is executed by an electronic device, see Figure 1 , the method comprises the following steps:

[0152] Step S101 , determining first target data and second target data, where the first target data is data greater than a first threshold among a plurality of first data included in a first data set, and the second target data is data less than a second threshold among a plurality of second data included in a second data set.

[0153] A data set is a collection of data. For a first data set and a second data set, the data contained in the first data set and the second data set are different, and the maximum value of the multiple first data included in the first data set is greater than the maximum value of the multiple second data included in the second data set, or in other words, the average value of the multiple first data included in the first data set is greater than the average value of the multiple second data included in the second data set. The data in the first data set is larger and the data in the second data set is smaller. When the data in the first data set overflows, the smaller data in the second data set is used to store the overflowed data in the first data set.

[0154] For the first data set, when the data bits of the first data in the first data set exceed the maximum data bits corresponding to the first data set, that is, when the first data is greater than a first threshold, the first data is determined as the first target data. The first threshold is related to the maximum data bits corresponding to the first data set. For example, if the maximum data bits corresponding to the first data set are 10 bits, then the first threshold is 1023; if the maximum data bits corresponding to the first data set are 14 bits, then the first threshold is 16383.

[0155] For the second data set, when the second data set is used to store data that overflows from the first data set, it is necessary to ensure that the second data set does not overflow after storing the data in the first data set. Therefore, when the second data set is less than a second threshold, the second data set is determined as the second target data. The second threshold is related to the maximum data bit corresponding to the second data set. For example, if the maximum data bit corresponding to the second data set is 10 bits, then the second threshold is 100; if the maximum data bit corresponding to the second data set is 14 bits, then the second threshold is 1000.

[0156] Step S102, extracting first information from the first target data and adding the first information to the second target data, the first information is used to indicate the value of the first preset position in the first target data, the first preset position is located before the least significant bit, and the value of the first preset position is not 0.

[0157] Extracting the first information from the first target data, that is, extracting the value of the first preset position from the first target data, and the first target data after extracting the first information no longer contains the value. The first preset position is located before the least significant bit, and the value of the first preset position is not 0. For example, if the first preset position is the most significant bit and the first target data is 7999, then 7 is extracted from the first target data, and the first target data after extracting the first information is 999. For another example, if the first preset position is the second most significant bit and the first target data is 7999, then 9 is extracted from the first target data, and the first target data after extracting the first information is 799.

[0158] The first information is appended to the second target data. This means that the value extracted from the first target data is added to the second target data. For example, the value can be appended before the most significant bit of the second target data, or after the most significant bit and before the second most significant bit of the second target data. For example, if the first information is 7 and the second target data is 49, the second target data after appending the first information is 749. Alternatively, the second target data after appending the first information can be 479.

[0159] Step S103 : determining a third data set based on the first data excluding the first target data and the first target data after the first information is extracted.

[0160] The third data set is a data set obtained by processing some data in the first data set, and includes the first target data after the first information is extracted and the first data in the first data set without the first information being extracted.

[0161] Step S104 : determining a fourth data set based on the second data excluding the second target data and the second target data after the first information is added.

[0162] The fourth data set is a data set obtained by processing some data in the second data set, and includes the second target data with the first information added thereto and the second data in the second data set without the first information added thereto.

[0163] The method provided by the embodiment of the present disclosure makes full use of the data bits of the data in the second data set, and saves the first information of the larger data in the first data set into the smaller data in the second data set, that is, the data overflowing from the first data set is saved in the second data set. While ensuring that the data in the first data set and the second data set are completely saved, the use of memory is reduced, so that when transmitting the data in the first data set, the power consumption of the transmission can be reduced, the transmission rate can be increased, and the performance of the device can be improved.

[0164] Figure 2 is a flow chart showing a data processing method according to an exemplary embodiment, which is executed by an electronic device, see Figure 2 , the method comprises the following steps:

[0165] Step S201: Acquire a first data set and a second data set.

[0166] The first data set includes a plurality of first data, and the second data set includes a plurality of second data. The maximum data bits corresponding to the first data set and the maximum data bits corresponding to the second data set may be the same or different. For example, the maximum data bits corresponding to the first data set and the maximum data bits corresponding to the second data set are both 10 bits.

[0167] In one example, taking the first data set as first image data (image data of a long-exposure exposure image) and the second data set as second image data (image data of a short-exposure exposure image) as an example, the first data set is shown in Table 1 below, and the second data set is shown in Table 2 below:

[0168] Table 1

[0169] 1023 1999 3500 2538 799 8000 563 200 679

[0170] Table 2

[0171] 40 77 135 98 31 301 17 7 27

[0172] Each value in Table 1 and Table 2 represents a pixel parameter.

[0173] In some embodiments, the number of the first data sets may be one or more, and the number of the second data sets may also be one or more.

[0174] Step S202 : determining first target data from a plurality of first data in the first data set.

[0175] The first target data is data in the first data set that is greater than the first threshold. The number of first target data can be one or more. In one example, the first data set is as shown in Table 1 above. When the first threshold is 1023, the first target data are 1999, 3500, 2538, and 8000.

[0176] Step S203: determining second target data from the plurality of second data in the second data set.

[0177] The second target data is data in the second data set that is less than the second threshold. The number of second target data can be one or more. In one example, the second data set is as shown in Table 2 above. When the second threshold is 100, the second target data are 40, 77, 98, 31, 17, 7, and 27.

[0178] Step S204: extracting first information from the first target data.

[0179] The first information is used to indicate a value of a first preset position in the first target data. The first preset position may be the highest bit in the data.

[0180] In some embodiments, when the first preset position is the highest bit, and the value of the second highest bit in the first target data is 0, the value of the second highest bit and the value of the lowest bit in the first target data are swapped to obtain swapped first target data; and the first information is extracted from the swapped first target data. The second highest bit can be the second highest bit in the data, and the lowest bit can be the lowest bit in the data. For example, if the first target data is 3023, the value of the second highest bit is 0, and the value of the lowest bit is 3, then 0 and 3 are swapped to obtain the swapped first target data of 3320.

[0181] In some embodiments, considering that the value of the lowest bit of the first target data after the swap is 0, if the lowest bit of other first data is also 0, it is impossible to tell whether the data is the first target data. Therefore, when the value of the lowest bit in the first data is 0, the first data is added to or subtracted from the preset value to obtain the updated first data. The preset value is an odd number, for example, the preset value is 1, 3 or other odd numbers. Of course, in order to make the updated first data as close as possible to the original first data, the preset value can take the minimum value of 1. For example, if the first data is 3330 and the value of the lowest bit is 0, then 1 is added to 3330 to obtain the updated first data 3331, or 1 is subtracted from 3330 to obtain the updated first data 3329.

[0182] In one example, when there are multiple first target data, based on the data set shown in Table 1 above, the first information extracted from the first target data is as shown in Table 3 below:

[0183] Table 3

[0184] 1023 (1)999 (3)500 (2)538 799 (7)999 563 200 679

[0185] Among them, 1, 3, 2 and 7 are the extracted first information.

[0186] In some embodiments, when the first preset position is not the highest bit, there is no need to exchange the values ​​at different positions in the first target data, but the first information can be directly extracted from the first target data.

[0187] Step S205 , converting the type of the second target data into the fourth type; adding the first information to the converted second target data to obtain the second target data after the first information is added.

[0188] In the embodiment of the present disclosure, in order to facilitate subsequent differentiation between which second data have the first information added and which have not, the type of the second target data is converted to the fourth type, while the type of the other second data without the first information added is converted to the third type. The third type is different from the fourth type; when the third type is an even number, the fourth type is an odd number, and when the third type is an odd number, the fourth type is an even number.

[0189] In some embodiments, converting the type of the second target data to the fourth type includes: when the type of the second target data itself is the fourth type, the second target data remains unchanged; when the type of the second target data is the third type, adding the second target data to a preset value or subtracting the preset value from the second target data to obtain the converted second target data. The preset value is an odd number. For example, if the third type is an even number and the fourth type is an odd number, when the second target data is 8, 1 can be added to 8 to obtain the converted second target data 9, or 1 can be subtracted from 8 to obtain the converted second target data 7.

[0190] In some embodiments, the first information is added to the converted second target data to obtain the second target data after adding the first information, including: adding the first information before the highest bit of the converted second target data, for example, the first information is 3, the converted second target data is 10, then the second target data after adding the first information is 310; or, adding the first information between the highest bit and the second highest bit of the converted second target data, for example, the first information is 3, the converted second target data is 10, then the second target data after adding the first information is 130. In the special case where the converted second target data is a single digit, the first information is added before the highest bit of the converted second target data. Of course, there may be other ways of adding, and the embodiments of the present disclosure are not limited to this.

[0191] In some embodiments, when there are multiple first target data and multiple second target data, extracting the first information from the first target data and adding the first information to the second target data includes: extracting the first information from each first target data; and sequentially adding each first information to the corresponding second target data according to the order of arrangement of the multiple first target data in the first data set and the order of arrangement of the multiple second target data in the second data set. For example, the first information of the first first target data is added to the first second target data, the first information of the second second target data is added to the second second target data, and so on until the first information of the Nth first target data is added to the Nth second target data, where N is an integer greater than 1.

[0192] In one example, based on Tables 1, 2, and 3 above, the type of the second target data in Table 2 is converted to an even number, as shown in Table 4 after the conversion. Multiple second target data in the second data set are added with the first information, as shown in Table 5 below:

[0193] Table 4

[0194] 40 78 135 98 32 301 18 8 28

[0195] Table 5

[0196] 140 378 135 298 732 301 18 8 28

[0197] It should be noted that when the number of second target data is greater than or equal to the number of first target data, the first information of each first target data is added to the corresponding second target data in sequence, starting from the first second target data; when the number of second target data is less than the number of first target data, the same number of first target data as the second target data is first selected from multiple first target data, wherein the selected first target data is greater than the unselected first target data, and then the first information of the selected first target data is added to the corresponding second target data.

[0198] Step S206, converting the type of the first data except the first target data into the first type; converting the type of the first target data after extracting the first information into the second type; and determining a third data set based on the converted first data and the converted first target data.

[0199] In the disclosed embodiment, to facilitate subsequent differentiation between data from which the first information is extracted and data from which the first information is not extracted, the type of the first data other than the first target data is converted to the first type; and the type of the first target data after the first information is extracted is converted to the second type. The first type and the second type are different; when the first type is an even number, the second type is an odd number; and when the first type is an odd number, the second type is an even number.

[0200] In some embodiments, converting the type of first data other than the first target data to the first type includes: when the type of the first data is the first type, keeping the first data unchanged; when the type of the first data is the second type, adding or subtracting the first data from a preset value to obtain converted first data, wherein the preset value is an odd number, and when the first type is an even number and the first preset position is the highest bit, the value of the lowest bit in the converted first data is not 0. For example, if the first type is an even number and the first data is 9, then 9 is subtracted by 1 to obtain the converted first data 8, but 9 cannot be added by 1 to obtain the converted first data 10. By ensuring that the value of the lowest bit in the first data from which the first information has not been extracted is not 0, the converted first data is distinguished from the first target data, making it easier to subsequently distinguish which data has had the first information extracted and which data has not.

[0201] In some embodiments, when the first preset position is the highest bit, converting the type of the first target data after extracting the first information into the second type includes: when the type of the first target data after extracting the first information is the second type, keeping the first target data after extracting the first information unchanged; or, when the value of the lowest bit in the first target data after extracting the first information is 0, keeping the first target data after extracting the first information unchanged. For example, if the second type is an odd number and the first target data after extracting the first information is 330, although the type of the first target data after extracting the first information is an even number, the first target data after extracting the first information remains unchanged. Or, when the value of the lowest bit in the first target data after extracting the first information is not 0 and the type of the first target data after extracting the first information is the first type, adding or subtracting the preset value from the first target data after extracting the first information to obtain the converted first target data. For example, if the first target data after extracting the first information is 342 and the second type is an odd number, adding 1 to 342 to obtain the converted first target data 343, or subtracting 1 from 342 to obtain the converted first target data 341.

[0202] In one example, based on Table 1 and Table 3 above, when the first type is an odd number and the second type is an even number, the third data set is as shown in Table 6 below:

[0203] Table 6

[0204] 1023 998 500 538 799 998 563 199 679

[0205] Step S207, converting the type of the second data except the second target data into a third type; determining a fourth data set based on the converted second data and the second target data after adding the first information, the type of the second target data after adding the first information is the fourth type.

[0206] In some embodiments, the type of the second data other than the second target data is converted to the third type, including: when the type of the second data itself is the third type, keeping the second data unchanged; when the type of the second data is the fourth type, adding the second data to a preset value or subtracting the second data from the preset value to obtain the converted second data.

[0207] Regarding the type conversion, optionally, all second data in the second data set are converted into the third type, and then the second target data are converted into the fourth type.

[0208] In some embodiments, after the third and fourth data sets are determined, in a data storage scenario, the third and fourth data sets are stored; in a data transmission scenario, the third and fourth data sets are sent. Sending the third and fourth data sets includes: sending the third and fourth data sets to another electronic device; or sending the third and fourth data sets to another module in the electronic device via one module.

[0209] It should be noted that the above embodiment uses a single first data set as an example. In another embodiment, the number of first data sets can be multiple. When there are multiple first data sets and the number of first target data in each first data set is multiple, each piece of first information is sequentially added to the corresponding second target data according to the order of arrangement of the multiple first target data in the first data set and the order of arrangement of the multiple second target data in the second data set, including: sequentially adding each piece of first information to the corresponding second target data according to the order of arrangement of the multiple first data sets, the order of arrangement of the multiple first target data in each first data set, and the order of arrangement of the multiple second target data in the second data set. For example, first, for the first first data set, the first information of the N first target data in the first first data set is sequentially added to the first N second target data in the second data set. Then, for the second first data set, the first information of the M first target data in the second first data set is sequentially added to the N+1th to N+Mth second target data in the second data set. Subsequent first data sets are sequentially added according to the order of the second target data in the first data set until the first information of the last first target data in the last first data set is added.

[0210] In one example, two first data sets are used, one first data set is shown in Table 1 above, and the other first data set (image data of a normally exposed image) is shown in Table 7 below:

[0211] Table 7

[0212] 800 1537 2560 1952 614 6000 433 153 522

[0213] The second data set is shown in Table 2 above. According to the above embodiment, when the first type is an odd number, the second type is an even number, the third type is an odd number, and the fourth type is an even number, the data in Table 1, Table 2, and Table 7 are processed respectively, and finally the data sets shown in Table 8 (third data set), Table 9 (third data set), and Table 10 (fourth data set) are obtained:

[0214] Table 8

[0215] 1023 998 500 538 799 998 563 199 679

[0216] Table 9

[0217] 799 536 560 951 613 998 433 153 521

[0218] Table 10

[0219] 140 379 135 298 732 301 118 28 528

[0220] The method provided by the embodiment of the present disclosure makes full use of the data bits of the data in the second data set, and saves the first information of the larger data in the first data set into the smaller data in the second data set, that is, the data overflowing from the first data set is saved in the second data set. While ensuring that the data in the first data set and the second data set are completely saved, the use of memory is reduced, so that when transmitting the data in the first data set, the power consumption of the transmission can be reduced, the transmission rate can be increased, and the performance of the device can be improved.

[0221] Figure 3 is a flow chart showing a data processing method according to an exemplary embodiment, which is executed by an electronic device, see Figure 3 , the method comprises the following steps:

[0222] Step S301 , determining third target data and fourth target data, where the third target data is data of the second type among multiple third data included in the third data set, and the fourth target data is data of the fourth type among multiple fourth data included in the fourth data set.

[0223] Step S302 : extracting second information from the fourth target data and adding the second information to the third target data, where the second information is used to indicate a value of a second preset position in the fourth target data.

[0224] Extracting the second information from the fourth target data, that is, extracting the value at the second preset position from the fourth target data, and the fourth target data after extracting the second information no longer contains the value. The second preset position may be the highest bit, the second highest bit, or any other position other than the lowest bit in the fourth target data. For example, if the fourth target data is 749, then 7 is extracted from the fourth target data, and the fourth target data after extracting the second information is 49.

[0225] Add the second information to the third target data, that is, add the numerical value extracted from the fourth target data to the third target data. When adding the second information, determine the position to add the second information based on the position where the first information is extracted. Optionally, when the first information is the numerical value of the highest bit in the first target data, add the numerical value before the highest bit of the third target data. For example, if the second information is 7 and the third target data is 999, the third target data after adding the second information is 7999; or, when the first information is the numerical value of the second highest bit in the first target data, add the numerical value after the highest bit and before the second highest bit of the third target data. For example, if the second information is 7 and the third target data is 999, the third target data after adding the second information can also be 9799.

[0226] Step S303 : determining a fifth data set based on the third data excluding the third target data and the third target data after the second information is added.

[0227] Step S304 : determining a sixth data set based on the fourth data excluding the fourth target data and the fourth target data after the second information is extracted.

[0228] The method provided in the embodiments of the present disclosure can further decode the encoded third and fourth data sets to obtain fifth and sixth data sets. Furthermore, the data in the fifth data set does not significantly change compared to the first data set, and the data in the sixth data set does not significantly change compared to the second data set. Data accuracy can still be guaranteed through encoding and decoding. In a data transmission scenario, data is first encoded, the encoded data set is transmitted, and then the data set is decoded after transmission to obtain the decoded data. This can reduce power consumption and transmission rate during the data transmission process while ensuring data accuracy.

[0229] Figure 4 is a flow chart showing a data processing method according to an exemplary embodiment, which is executed by an electronic device, see Figure 4 , the method comprises the following steps:

[0230] Step S401 : Acquire a third data set and a fourth data set, where the third data set includes a plurality of third data and the fourth data set includes a plurality of fourth data.

[0231] Step S402 : determining third target data from a plurality of third data in the third data set.

[0232] The number of the third target data is one or more.

[0233] In some embodiments, determining the third target data includes: determining data belonging to the second type among the plurality of third data as the third target data.

[0234] In some embodiments, when the first preset position is the highest bit during the encoding process, determining the third target data includes: when the second type is an odd number, if the value of the lowest bit in the third data is 0, determining the third data as the third target data.

[0235] In one example, when the third data set is as shown in Table 8 above, the second type is an even number, and the third target data determined from the third data set includes 998, 500, 538, and 998. When the third data set is as shown in Table 9 above, the third target data determined from the third data set includes 536, 560, and 998.

[0236] Step S403 : determining fourth target data from the plurality of fourth data in the fourth data set.

[0237] In some embodiments, determining the fourth target data includes: determining data belonging to a fourth type among a plurality of fourth data as the fourth target data.

[0238] In one example, when the fourth data set is as shown in Table 10 above, the fourth type is an even number, and the fourth target data determined from the fourth data set include 140, 378, 298, 732, 118, 28, and 528.

[0239] Step S404: extract the second information from the fourth target data, and add the second information to the third target data.

[0240] The second information is used to indicate the value of a second preset position in the fourth target data. The second preset position can be the highest bit, the second highest bit, or other position in the data. The second preset position is determined according to the position where the first information is added. When the first information is added before the highest bit of the second target data, the second preset position is the highest bit. When the first information is added between the highest bit and the second highest bit of the second target data, the second preset position is the second highest bit.

[0241] Adding the second information to the third target data includes: adding the second information before the most significant bit of the third target data.

[0242] Step S405 : determining a fifth data set based on the third data excluding the third target data and the third target data after the second information is added.

[0243] In some embodiments, a fifth data set is determined based on the third data other than the third target data and the third target data after adding the second information, including: when the value of the lowest bit in the third target data after adding the second information is 0, the value of the lowest bit in the third target data after adding the second information is swapped with the value of the second highest bit to obtain the swapped third target data; and a fifth data set is determined based on the third data other than the third target data and the swapped third target data.

[0244] In one example, the fifth data set is shown in Table 11:

[0245] Table 11

[0246] 1023 1998 3500 2538 799 7998 563 199 679

[0247] Among them, 1998, 3500, 2538 and 7998 are the third target data after adding the second information.

[0248] Step S406 : determining a sixth data set based on the fourth data excluding the fourth target data and the fourth target data after the second information is extracted.

[0249] It should be noted that the above implementation method takes a third data set as an example. When there are multiple third data sets and the number of third target data in each third data set is multiple, each second information is added to the corresponding third target data in sequence according to the arrangement order of the multiple third target data in the third data set and the arrangement order of the multiple fourth target data in the fourth data set, including: adding each second information to the corresponding third target data in sequence according to the arrangement order of the multiple third data sets, the arrangement order of the multiple third target data in each third data set, and the arrangement order of the multiple fourth target data in the fourth data set.

[0250] For example, first, for the first third data set, determine the L third target data in the first third data set, determine the fourth target data arranged in the first L from the multiple fourth target data in the fourth data set, and then add the second information in the first to Lth fourth target data to the first to Lth third target data in the first third data set in sequence; then, for the second third data set, determine the K third target data in the second third data set, determine the fourth target data arranged in the L+1th to L+Kth from the multiple fourth target data in the fourth data set, and then add the second information in the L+1th to L+Kth fourth target data to the first to Kth third target data in the second third data set in sequence, until the last second information is added to the last third target data in the last third data set.

[0251] The method provided in the embodiments of the present disclosure can further decode the encoded third and fourth data sets to obtain fifth and sixth data sets. Furthermore, the data in the fifth data set does not significantly change compared to the first data set, and the data in the sixth data set does not significantly change compared to the second data set. Data accuracy can still be guaranteed through encoding and decoding. In a data transmission scenario, data is first encoded, the encoded data set is transmitted, and then the data set is decoded after transmission to obtain the decoded data. This can reduce power consumption and transmission rate during the data transmission process while ensuring data accuracy.

[0252] above Figures 1-4 When the data processing method shown is applied to the image data processing scenario, the image data processing process is as follows Figure 5 shown.

[0253] Figure 5 is a flowchart of an image data processing method according to an exemplary embodiment, which is executed by an electronic device. Figure 5 , the method comprises the following steps:

[0254] Step S501, capturing multiple exposure images with different exposure levels, where the multiple exposure images include at least a first exposure image and a second exposure image, and the exposure level of the first exposure image is greater than that of the second exposure image. The first image data is used to represent the first exposure image, and the second image data is used to represent the second exposure image.

[0255] Different image data is used to represent different exposure images. For example, when capturing HDR images, the first exposure image may be a long-exposure image or a normal-exposure image, and the second exposure image may be a short-exposure image or an even shorter-exposure image. The image data includes multiple pixel parameters, each of which represents a pixel in the exposure image. The pixel parameter can represent information such as the pixel value of the pixel and various processing algorithms performed on the pixel.

[0256] Step S502, determine a first target pixel parameter and a second target pixel parameter, where the first target pixel parameter is data greater than a first parameter threshold among a plurality of first pixel parameters included in the first image data, and the second target pixel parameter is data less than a second parameter threshold among a plurality of second pixel parameters included in the second image data.
