Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.
Because the problem of inaccurate test result of the image processing performance exists in the prior art, the embodiment of the invention provides a method and a device for testing the image processing performance in order to improve the accuracy of the test result of the image processing performance.
In an embodiment of the present invention, there is provided an image processing performance testing method, including:
carrying out image processing on the sample image to obtain a current processing result;
under the condition that the accumulated time for carrying out image processing on the sample image is less than the preset time, determining whether the current processing result of the sample image is the same as the historical processing result of the sample image, if so, adjusting the pixel value of a target pixel point in the sample image to obtain a new sample image, and returning to the step of carrying out image processing on the sample image;
and under the condition that the accumulated time for carrying out image processing on the sample image is not less than the preset time, obtaining a test result of the image processing performance of the electronic equipment according to the accumulated time and the accumulated times for carrying out image processing on the sample image.
As can be seen from the above, since each pair of sample images is subjected to image processing, the pixel values of the target pixel points in the sample images are subjected to primary transformation, so as to generate new sample images. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of the test result. In addition, the new sample image is obtained by adjusting the pixel value of the target pixel point in the original sample image, so that a plurality of different new sample images can be obtained on the basis of one sample image under the condition of not increasing the occupied space of the sample image, and the electronic equipment can be subjected to image processing performance test, thereby saving the storage space of the electronic equipment.
The following describes the method and apparatus for testing image processing performance according to the embodiments of the present invention with specific embodiments.
Referring to fig. 1, an embodiment of the present invention provides a flowchart of a first method for testing image processing performance, which may be implemented by the following steps S101 to S104.
S101: and carrying out image processing on the sample image to obtain a current processing result.
Specifically, the sample Image may be processed by a CPU (Central Processing Unit) installed in the electronic device, or may be processed by an Image Processing Unit installed in the electronic device, such as a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), an ISP (Image Signal Processor), an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or the like.
The number of sample images may be 1 or more, and when the number of sample images is plural, image processing may be sequentially performed on each sample image. The sample images may be images in the same image format or images in different image formats. For example, JPEG format, PNG format, WEPB format, HEIF format, and the like. The image content of the sample image may be any content, which is not limited in the embodiment of the present invention, for example, the image content may be a person, an animal, a plant, and the like.
The image processing may be image decoding or image encoding, or may be other image processing such as image recognition, image stitching, or image feature extraction. When the image processing is image decoding, the image decoding process may be completed in a bitmap factory manner, and a current processing result obtained after the image decoding is a bitmap.
S102: and under the condition that the accumulated time for carrying out image processing on the sample image is less than the preset time, determining whether the current processing result of the sample image is the same as the historical processing result of the sample image.
Specifically, the history processing result is: a processing result of the sample image obtained before the current processing result is obtained.
The accumulated time length is as follows: the cumulative total time length for image processing of all the sample images subjected to image processing, for example, if the time length for image processing of the sample image M is 2 seconds, and the time length for image processing of the sample image N is 3 seconds, the cumulative time length is 5 seconds.
In an embodiment of the present invention, if the current processing result is the same as the historical processing result, it indicates that the electronic device may directly read the previously generated historical processing result, and as the current processing result obtained by the current image processing, the electronic device does not actually perform image processing on the sample image, which may affect the accuracy of the test result of the image processing performance.
When the current processing result is different from the historical processing result, it is considered that the electronic device normally performs the image processing until now, and the accuracy of the test result of the image processing performance is not affected, so that the flow of the image processing performance test can be continued, and step S103 can be executed.
In addition, the time length required for the process of determining whether the current processing result of the sample image is the same as the historical processing result of the sample image is not counted in the accumulated time length, and whether the current processing result is the same as the historical processing result may be determined by a thread other than a thread executing image processing, so as to prevent the process of determining whether the current processing result is the same as the historical processing result from affecting the image processing process of the sample image.
S103: and adjusting the pixel value of the target pixel point in the sample image to obtain a new sample image.
Specifically, the target pixel point may be any pixel point in the randomly determined sample image, or may be a pixel point at a preset position. The number of target pixel points in the sample image can be any random number or a preset number.
Since a new sample image is obtained and the cumulative duration of image processing on the sample image is less than the preset duration, that is, the process of the image processing performance test is not yet ended, the process of the image processing performance test needs to be continuously executed, and the process returns to the step S101 to be continuously executed.
S104: and under the condition that the accumulated time for carrying out image processing on the sample image is not less than the preset time, obtaining a test result of the image processing performance of the electronic equipment according to the accumulated time and the accumulated times for carrying out image processing on the sample image.
Specifically, the accumulated time for performing image processing on the sample image is not less than the preset time, which indicates that the time for performing the image processing performance test on the electronic device has reached the preset time.
In an embodiment of the present invention, the accumulated number of times may be divided by the accumulated time duration, the calculation result may represent the number of sample images that can be processed by the electronic device in a unit time duration, and the calculation result may be used as a test result. However, since the value of the calculation result may be small, and the calculation result is directly used as the test result, the difference between the test results of different electronic devices may be small, and it is difficult to reflect the difference between the image processing performances of different electronic devices, so that in order to intuitively represent the image processing performance of the electronic devices, the calculation result may be multiplied by a first preset coefficient to be used as the test result. For example, the first predetermined coefficient may be 100, 1000, or the like.
As can be seen from the above, since each pair of sample images is subjected to image processing, the pixel values of the target pixel points in the sample images are subjected to primary transformation, so as to generate new sample images. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of the test result. In addition, the new sample image is obtained by adjusting the pixel value of the target pixel point in the original sample image, so that a plurality of different new sample images can be obtained on the basis of one sample image under the condition of not increasing the occupied space of the sample image, and the electronic equipment can be subjected to image processing performance test, thereby saving the storage space of the electronic equipment.
Referring to fig. 2, an embodiment of the present invention provides a flowchart of a second method for testing image processing performance, where, when there are images in multiple image formats in the sample image, the step S102 may be implemented in the following manner, compared with the embodiment shown in fig. 1.
The sample images for each image format are processed as follows S102A-S102B:
S102A: and under the condition that the accumulated time for carrying out image processing on the sample image is less than the preset time, judging whether a first accumulated sub-time for carrying out image processing on the sample image in an image format is less than a first preset sub-time.
And the sum of the first preset sub-time lengths corresponding to the image formats is equal to the preset time length.
Specifically, the first preset sub-durations corresponding to different image formats may be the same or different, and since the sum of the first preset sub-durations corresponding to different image formats is equal to the preset duration, the total accumulated duration of image processing on the sample image is equal to or greater than the preset duration under the condition that the first accumulated sub-duration of image processing on the sample image of each image format is not less than the first preset sub-duration.
In addition, the number of sample images per image format may be 1, that is, there are a plurality of different image formats for the sample images, and the number of sample images per image format is 1. The number of sample images in each image format may be multiple, that is, there are multiple different image formats for the sample images, and the number of sample images in each image format is multiple. The number of sample images of different image formats may be the same or different.
If the first cumulative sub-duration is less than the first preset sub-duration, the duration of image processing on the sample image in the image format has not reached the first preset sub-duration, and it is necessary to continue image processing on the sample image in the image format, and step S102B is executed.
And under the condition that the first accumulated sub-time length is not less than the first preset sub-time length, the time length for carrying out image processing on the sample image in the image format reaches the first preset sub-time length, the sample image in the image format does not need to be continuously subjected to image processing, and the step S101 is returned to, and the sample images in other image formats are processed.
In an embodiment of the present invention, image processing may be preferentially performed on a sample image in an image format, and when a first accumulated sub-time length for performing image processing on the sample image in the image format is not less than a first preset sub-time length, image processing may be performed on a sample image in a next image format. Only the first accumulated sub-period of image processing for the sample image of one image format needs to be timed at the same time during the process of performing the image processing performance test.
The image processing may be performed on each sample image in a sequential loop, and the sequence may be any sequence, i.e., the sequence is independent of the image format of the sample image. That is, when the first accumulated sub-time length of the image processing on the sample image of one image format is smaller than the first preset sub-time length, the image processing on the sample image of another image format is started, and after the image processing on each sample image is completed once, the next round of image processing on each sample image is started. The first accumulated sub-durations of the respective image formats need to be clocked separately at the same time.
S102B: it is determined whether a current processing result of the sample image in the image format is the same as a historical processing result of the sample image in the image format.
In an embodiment of the present invention, if the current processing result of the sample image in the image format is the same as the historical processing result, it indicates that the electronic device may directly read the historical processing result of the previously generated sample image in the image format, and as the current processing result obtained by the current image processing, the electronic device does not actually perform image processing on the sample image in the image format, which may affect the accuracy of the test result of the image processing performance.
If the current processing result of the sample image in the image format is different from the historical processing result, it is considered that the electronic device normally performs the image processing on the sample image in the image format until now, and the accuracy of the test result of the image processing performance is not affected, so that the flow of the image processing performance test can be continued, and step S103 is executed.
Compared to the previous embodiment shown in FIG. 1, step S104 can be implemented by the following steps S104A-S104B.
S104A: and determining a test sub-result of the image processing sub-performance of the image processing of the image in the image format by the electronic equipment according to the first accumulative sub-time and the first accumulative sub-times of the image processing of the sample image in the image format for each image format.
Specifically, for each image format, the first accumulated sub-number of times of the image format may be divided by the first accumulated sub-duration, the calculation result may represent the number of sample images of the image format that can be processed by the electronic device in a unit duration, and the calculation result may be used as a test sub-result. However, since the value of the calculation result may be small, and the calculation result is directly used as the test sub-result, the difference between the test sub-results of different electronic devices may be small, and it is difficult to reflect the difference between the image processing performances of different electronic devices, so that in order to intuitively represent the image processing performance of the electronic devices, the calculation result may be multiplied by a second preset coefficient to be used as the test result.
Specifically, since the calculation result is multiplied by the second preset coefficient only to increase the size of the calculation result, the size ratio relationship between the calculation results corresponding to different image formats cannot be changed, and thus the second preset coefficient is the same for different image formats. For example, the second preset coefficient may be 100, 1000, or the like.
S104B: and determining the test result of the image processing performance of the electronic equipment according to each test sub-result.
Specifically, the statistical results such as the sum, the weighted sum, the average, and the weighted average of the respective test sub-results may be used as the test results of the image processing performance.
In addition, the test result of the image processing performance of the electronic device can also be determined according to the following formula:
Figure BDA0002920952420000131
wherein G isnFor the above test results, i is the index of the image format, n represents the total number of image formats, fiWeight, x, corresponding to the ith image formatiAnd testing the sub-result corresponding to the ith image format.
In particular, the test result calculated according to the above formula may be referred to as a weighted geometric mean of the test sub-results.
As can be seen from the above, because the sample images in different image formats include different information, and the same electronic device performs different image processing performances on the sample images in different image formats, when the sample images include images in different image formats, the test sub-results of the electronic device performing image processing on the sample images in different image formats are respectively calculated, and then the test results are obtained according to the test sub-results, so that the calculated test results can reflect the image processing performances of the electronic device performing image processing on the sample images in different image formats, and the determined image processing performances are more accurate.
Referring to fig. 3, a flowchart of a third method for testing image processing performance is provided in the embodiment of the present invention, and in the case that the number of the sample images is greater than 1, compared with the embodiment shown in fig. 1, the step S102 may be implemented in the following manner.
Each sample image is processed as per the following steps S102C-S102D.
S102C: and under the condition that the accumulated time length for carrying out the image processing on the sample image is less than the preset time length, judging whether a second accumulated sub-time length for carrying out the image processing on the sample image is less than a second preset sub-time length.
And the sum of the second preset sub-time lengths corresponding to the sample images is equal to the preset time length.
Specifically, the second preset sub-durations corresponding to different sample images may be the same or different, and since the sum of the second preset sub-durations corresponding to different sample images is equal to the preset duration, the total accumulated duration of the image processing on the sample images is greater than or equal to the preset duration under the condition that the second accumulated sub-duration of the image processing on each sample image is not less than the second preset sub-duration.
In addition, the image formats of different sample images may be the same, that is, there is one image format of the sample images, and the number of the sample images in the image format is multiple. The image formats of different sample images may be different, that is, there are multiple different image formats for the sample images, and the number of the sample images in each image format may be one or multiple.
If the second accumulated sub-duration is less than the second preset sub-duration, the duration of image processing on the sample image has not reached the second preset sub-duration, and image processing needs to be continued on the sample image, and step S102D is executed.
And under the condition that the second accumulated sub-time length is not less than the second preset sub-time length, the time length for carrying out the image processing on the sample image reaches the second preset sub-time length, the sample image does not need to be continuously subjected to the image processing, and the step S101 is returned to, and other sample images are processed.
In an embodiment of the present invention, image processing may be preferentially performed on one sample image, and when the second accumulated sub-time length for performing image processing on the sample image is not less than the second preset sub-time length, image processing may be performed on the next sample image. In the process of performing the image processing performance test, the second accumulated sub-durations of only one sample image need to be respectively timed.
The image processing may also be performed on each sample image in a sequential and cyclic manner, that is, when the second accumulated sub-time length for performing the image processing on one sample image is less than the second preset sub-time length, the image processing on the next sample image is started, and after the image processing on each sample image is completed once, the next round of image processing on each sample image is started again. The second accumulated sub-durations for the respective sample images need to be clocked simultaneously.
S102D: it is determined whether the current processing result of the sample image is the same as the historical processing result of the sample image.
In an embodiment of the present invention, if the current processing result of the sample image is the same as the historical processing result, it indicates that the electronic device may directly read the historical processing result of the previously generated sample image, and as the current processing result obtained by the current image processing, the electronic device does not actually perform image processing on the sample image, which may affect the accuracy of the test result of the image processing performance.
When the current processing result of the sample image is different from the historical processing result, it is considered that the electronic device normally performs the image processing on the sample image until now, and the accuracy of the test result of the image processing performance is not affected, so that the flow of the image processing performance test can be continued.
In addition, under the condition that the second accumulated time length for carrying out image processing on each sample image is not less than the second preset time length, the sum of the second accumulated sub-time lengths of each sample image is the accumulated time length, and the sum of the second accumulated sub-times for carrying out image processing on each sample image is the accumulated times.
As can be seen from the above, in the embodiment provided by the present invention, a plurality of sample images are provided for testing the image processing performance of the electronic device, and because the image complexity of different sample images is often different, the time required for the electronic device to perform image processing on different images is different. The test of the image processing performance by adopting a plurality of sample images can enable the test result obtained by the test to reflect the image processing performance of the electronic equipment for processing the sample images with different image complexity, so that the determined image processing performance is more accurate.
Referring to fig. 4, a flowchart of a fourth method for testing image processing performance according to an embodiment of the present invention further includes the following step S105 before the step S101, compared to the embodiment shown in fig. 1.
S105: and reading the sample image into the memory in a binary stream mode.
Specifically, in the process of image processing of the sample image by the electronic device, the sample image is read from the memory for image processing.
The binary stream includes binary numbers representing different sample images, and the binary numbers corresponding to the same sample image are adjacent to each other in the binary stream. Different pixel points in the sample image correspond to different binary numbers.
Compared to the aforementioned embodiment shown in fig. 1, the above step S103 can be implemented by the following step S103A.
S103A: and adjusting the value of the binary digit used for expressing the target pixel point in the binary digit stream corresponding to the sample image.
Specifically, since the binary stream only includes two numbers, i.e., 1 and 0, the value of the binary digit used for representing the target pixel point can be adjusted from 1 to 0, or from 0 to 1, so as to adjust the value of the binary digit used for representing the target pixel point.
In an embodiment of the present invention, each binary digit used for representing the target pixel point may be adjusted, and values of a part of binary digits used for representing the target pixel point may also be randomly adjusted.
As can be seen from the above, since the sample image is read into the memory in the form of a binary stream before the sample image is subjected to image processing, the electronic device can directly obtain the sample image from the memory for image processing when the sample image needs to be subjected to image processing. Therefore, the counted accumulated time for processing the sample image does not include the time required for reading the sample image into the memory, so that the accuracy of the counted accumulated time is improved, and the accuracy of the image processing performance determined according to the accumulated time is improved.
Corresponding to the foregoing method for testing processor performance, referring to fig. 5, an embodiment of the present invention further provides a schematic structural diagram of a first apparatus for testing image processing performance, where the apparatus includes:
the image processing module 501 is configured to perform image processing on the sample image to obtain a current processing result;
a pixel value adjusting module 502, configured to determine whether a current processing result of the sample image is the same as a historical processing result of the sample image when an accumulated time for performing image processing on the sample image is less than a preset time, and if the current processing result is different from the historical processing result of the sample image, adjust a pixel value of a target pixel point in the sample image to obtain a new sample image, and return to the image processing module 501;
a result obtaining module 503, configured to obtain a test result of the image processing performance of the electronic device according to the cumulative duration and the cumulative number of times of image processing performed on the sample image, when the cumulative duration of image processing performed on the sample image is not less than a preset duration.
As can be seen from the above, since each pair of sample images is subjected to image processing, the pixel values of the target pixel points in the sample images are subjected to primary transformation, so as to generate new sample images. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of the test result. In addition, the new sample image is obtained by adjusting the pixel value of the target pixel point in the original sample image, so that a plurality of different new sample images can be obtained on the basis of one sample image under the condition of not increasing the occupied space of the sample image, and the electronic equipment can be subjected to image processing performance test, thereby saving the storage space of the electronic equipment.
Referring to fig. 6, a schematic structural diagram of a second image processing performance testing apparatus according to an embodiment of the present invention is provided, where when images in multiple image formats exist in the sample image, compared with the embodiment shown in fig. 5, the pixel value adjusting module 502 includes:
the sample image of each image format is processed by the following image processing submodule 502A;
the image processing sub-module 502A is specifically configured to:
judging whether a first accumulated sub-time length for carrying out image processing on a sample image in an image format is less than a first preset sub-time length or not, wherein the sum of the first preset sub-time lengths corresponding to all the image formats is equal to the preset time length;
if the current processing result of the sample image in the image format is smaller than the historical processing result of the sample image in the image format, determining whether the current processing result of the sample image in the image format is the same as the historical processing result of the sample image in the image format, if the current processing result of the sample image in the image format is different from the historical processing result of the sample image in the image format, adjusting the pixel value of a target pixel point in the sample image to obtain a new sample image, and;
if not, returning to execute the image processing module 501 to process sample images in other image formats;
the result obtaining module 503 includes:
the sub-result determining sub-module 503A is configured to determine, for each image format, a sub-result of testing the image processing sub-performance of the image processing performed on the image in the image format by the electronic device according to a first accumulated sub-time and a first accumulated sub-time for performing the image processing on the sample image in the image format under the condition that the accumulated time for performing the image processing on the sample image is not less than a preset time;
the result determining sub-module 503B is configured to determine a test result of the image processing performance of the electronic device according to each test sub-result.
As can be seen from the above, because the sample images in different image formats include different information, and the same electronic device performs different image processing performances on the sample images in different image formats, when the sample images include images in different image formats, the test sub-results of the electronic device performing image processing on the sample images in different image formats are respectively calculated, and then the test results are obtained according to the test sub-results, so that the calculated test results can reflect the image processing performances of the electronic device performing image processing on the sample images in different image formats, and the determined image processing performances are more accurate.
In an embodiment of the present invention, the result determining sub-module 503B is specifically configured to:
determining a test result of the image processing performance of the electronic equipment according to the following formula:
Figure BDA0002920952420000181
wherein G isnFor the test results, i is the index of the image format, n denotes the total number of image formats, fiWeight, x, corresponding to the ith image formatiAnd testing the sub-result corresponding to the ith image format.
In an embodiment of the present invention, when the number of the sample images is greater than 1, the pixel value adjusting module 502 is specifically configured to:
each sample image is processed as follows:
judging whether a second accumulated sub-time length for carrying out image processing on the sample images is less than a second preset sub-time length or not, wherein the sum of the second preset sub-time lengths corresponding to the sample images is equal to the preset time length;
if the current processing result of the sample image is smaller than the historical processing result of the sample image, determining whether the current processing result of the sample image is the same as the historical processing result of the sample image, if the current processing result of the sample image is not the same as the historical processing result of the sample image, adjusting the pixel value of a target pixel point in the sample image to obtain a new sample image, and returning to the image processing module;
if not, the image processing module 501 is returned to be executed to process other sample images.
As can be seen from the above, in the embodiment provided by the present invention, a plurality of sample images are provided for testing the image processing performance of the electronic device, and because the image complexity of different sample images is often different, the time required for the electronic device to perform image processing on different images is different. The test of the image processing performance by adopting a plurality of sample images can enable the test result obtained by the test to reflect the image processing performance of the electronic equipment for processing the sample images with different image complexity, so that the determined image processing performance is more accurate.
In an embodiment of the present invention, the apparatus further includes:
the image reading module is used for reading the sample image into the memory in a binary stream mode;
the pixel value adjusting module 502 is specifically configured to:
and under the condition that the accumulated time for performing image processing on the sample image is less than the preset time, determining whether the current processing result of the sample image is the same as the historical processing result of the sample image, if so, adjusting the value of the binary bit used for representing the target pixel point in the binary stream corresponding to the sample image, and returning to execute the image processing module 501.
In one embodiment of the present invention, the image processing is: image decoding or image encoding.
As can be seen from the above, since the sample image is read into the memory in the form of a binary stream before the sample image is subjected to image processing, the electronic device can directly obtain the sample image from the memory for image processing when the sample image needs to be subjected to image processing. Therefore, the counted accumulated time for processing the sample image does not include the time required for reading the sample image into the memory, so that the accuracy of the counted accumulated time is improved, and the accuracy of the image processing performance determined according to the accumulated time is improved.
An embodiment of the present invention further provides an electronic device, as shown in fig. 7, including a processor 701, a communication interface 702, a memory 703 and a communication bus 704, where the processor 701, the communication interface 702, and the memory 703 complete mutual communication through the communication bus 704,

When the electronic equipment provided by the embodiment of the invention is applied to testing the image processing performance, because each pair of sample images is subjected to image processing once, the pixel values of target pixel points in the sample images are subjected to one-time conversion, and a new sample image is generated. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of the test result. In addition, the new sample image is obtained by adjusting the pixel value of the target pixel point in the original sample image, so that a plurality of different new sample images can be obtained on the basis of one sample image under the condition of not increasing the occupied space of the sample image, and the electronic equipment can be subjected to image processing performance test, thereby saving the storage space of the electronic equipment.

When the computer program stored in the computer-readable storage medium provided in this embodiment is used to test the image processing performance, since each pair of sample images is subjected to image processing once, the pixel values of the target pixel points in the sample images are subjected to a conversion once, so as to generate new sample images. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid. Therefore, the scheme provided by the embodiment of the invention can improve the accuracy of the test result. In addition, the new sample image is obtained by adjusting the pixel value of the target pixel point in the original sample image, so that a plurality of different new sample images can be obtained on the basis of one sample image under the condition of not increasing the occupied space of the sample image, and the electronic equipment can be subjected to image processing performance test, thereby saving the storage space of the electronic equipment.

When the computer program product provided by this embodiment is executed to test the image processing performance, since each pair of sample images is subjected to image processing once, the pixel values of the target pixel points in the sample images are transformed once, and a new sample image is generated. Therefore, the sample images are different in each image processing process of the electronic device, and therefore if the electronic device normally performs image processing on the sample images, the current processing results obtained in each image processing process are different. Therefore, if it can be determined that the current processing result of the sample image is different from the historical processing result, it can be considered that the electronic device normally performs image processing in the process of testing the image processing performance of the electronic device. Otherwise, it may be considered that the electronic device directly reads the processing result generated earlier as the processing result generated later, and does not substantially perform image processing, and the test result of testing the image processing is invalid.
