s101: the size of the image to be stored is obtained, the number of sectors needing to be erased is calculated according to the size of the image to be stored and the size of the sectors obtained in advance, and the sectors are erased from the address to be stored according to the number of the sectors.
In the embodiment of the present invention, the number of the images to be stored may be one or more, and if there are a plurality of images to be stored, the images may be sequentially stored in sequence.
Dividing the size of the image to be stored by the size of the sector to obtain the number of sectors needing to be erased, and erasing the sector from the address to be stored, wherein the number of the erased sectors is the number of the sectors needing to be erased. The address to be stored is the current storage address, that is, the storage space before the address to be stored stores data. The size of each sector is fixed, for example the size of each sector may be 128 KB.
Optionally, if the remaining storable space of the sector to which the address to be stored belongs can store the size of the image to be stored and the data of the image to be stored, that is, the sum of the first preset size and the size of the image to be stored is less than or equal to the size of the remaining storable space of the sector to which the address to be stored belongs, the sector does not need to be erased, and the step S102 is directly performed. The first storage space with the preset size is a storage space with a preset size for storing the size of the image to be stored.
If the sector to which the address to be stored belongs is erased, erasing is started from the next sector of the sector, and the number of the erased sectors is the number of the sectors needing to be erased. If the value obtained by dividing the size of the image to be stored by the size of the sector is a decimal, rounding up the decimal to obtain the number of the sectors needing to be erased.
S102: and writing the size of the image to be stored into the address to be stored, and updating the address to be stored.
In the embodiment of the invention, before the data of the image to be stored is stored, the size of the image to be stored is written into the address to be stored, and the address to be stored is updated. The area for storing the size of the image to be stored is an identification area of the image to be stored, and may also be referred to as an index area of the image to be stored, and the identification area of each image may be used to segment the continuously stored image, and may also be used to know the size of the image, so as to facilitate reading.
Specifically, the address to be stored is updated by shifting the address to be stored backward by a first preset size, so as to obtain an updated address to be stored. The first preset size is a preset space for storing the size of the image to be stored, and may be set according to actual requirements, for example, may be set to 4 bytes.
S103: and acquiring data of the image to be stored, writing the data of the image to be stored into the updated address to be stored, and obtaining a new address to be stored after the data of the image to be stored is written.
In the embodiment of the invention, the data of the image to be stored is acquired, and the data of the image to be stored is written in from the updated address to be stored. And after the data of the image to be stored is written, a new address to be stored can be obtained. The new address to be stored is obtained by shifting the updated address to be stored backward, and the backward shifted address is the size of the image to be stored.
S104: and if the next image to be stored exists, taking the next image to be stored as a new image to be stored, and continuing to execute the step of obtaining the size of the image to be stored.
When the number of the images to be stored is greater than one, that is, there is a next image to be stored, at this time, the next image to be stored is used as a new image to be stored, and the step S101 is returned to execute in a loop according to the new address to be stored until all the images to be stored are stored.
And if the number of the images to be stored is one, finishing the image storage.
As can be seen from the above description, in the embodiment of the present invention, the size of the image to be stored is written into the address to be stored, the address to be stored is updated, the data of the image to be stored is written into the updated address to be stored, and after the data of the image to be stored is written into the address to be stored, a new address to be stored is obtained, if there is a next image to be stored, the next image to be stored is used as a new image to be stored, and the step of obtaining the size of the image to be stored is continuously performed, so that continuous storage of the image can be realized, waste of storage space is reduced, and storage performance is improved; by storing the size of the image before each image data, it is possible to increase the identification area before each image data is stored, to segment the respective images from each other, while the identification area indicates the size of each image, to facilitate reading.

S202: and after the data of the image to be stored is written, reading the written data of the image to be stored from the updated address to be stored, and calculating a second check code according to the read written data.
After the data of the image to be stored is completely written, reading the written data of the image to be stored from the address of the data of the image to be stored, namely the updated address to be stored, and calculating a second check code according to the read data of the image to be stored. The method for calculating the second check code is the same as the method for calculating the first check code, and the second check code may be a CRC check code.
S203: and if the first check code is the same as the second check code, continuing to execute the step of obtaining a new address to be stored after the data of the image to be stored is written.
In the embodiment of the invention, whether the written data of the image to be stored is correct and complete can be judged by comparing whether the first check code and the second check code are the same.
If the first check code is the same as the second check code, which indicates that the written data of the image to be stored is correct and complete, the step of "obtaining a new address to be stored" after the data of the image to be stored is written "in step S103 may be continuously performed. The next image to be stored may continue to be stored.
S204: and if the first check code is different from the second check code, prompting image storage failure information and quitting the image storage process.
And if the first check code and the second check code are different, which indicates that the written data of the image to be stored may be wrong or incomplete, directly prompting the user of image storage failure information, and exiting the image storage process.
As can be seen from the above description, in the embodiment of the present invention, by calculating the first check code according to the data of the image to be stored before writing, calculating the second check code according to the read data of the image to be stored after writing, and comparing whether the first check code and the second check code are the same, it can be determined whether the written data of the image to be stored is correct and complete.

In the embodiment of the present invention, the third check code may be a CRC check code. The CRC operation may be performed according to the size of the image to be stored, and the third check code may be obtained. Other existing methods can also be used to calculate the third check code according to the size of the image to be stored. The third check code is used for confirming the validity of the address.
The size of the image to be stored and the third check code can be written into the address to be stored together, and then the address to be stored is updated. Specifically, starting from the address to be stored, writing the size of the image to be stored and a third check code into a storage space with a second preset size; and updating the address to be stored according to the address to be stored and the second preset size. The second preset size may be set according to actual requirements, for example, the second preset size may be set to 6 bytes, the size of the image to be stored may be 4 bytes, and the third check code may be stored in 2 bytes. And the address to be stored is shifted backwards by the address with the second preset size to obtain an updated address to be stored.
In an embodiment of the present invention, the step S102 may include the following steps:
writing the size of the image to be stored into a first preset size of storage space from the address to be stored;
and updating the address to be stored according to the address to be stored and the first preset size.
In the embodiment of the invention, the size of the image to be stored is written into the storage space with the first preset size. And the address to be stored is shifted backwards by the first preset size to obtain an updated address to be stored.
When the images need to be read, the storage addresses and the image sizes of all the images in NorFlash can be obtained only by searching from the NorFlash image initial addresses one by one according to the sequence of the stored structure array (the identification area and the image data area). And applying for a memory buffer area according to the storage address and the image size, and reading the image from NorFlash according to the storage address and the image size so as to display the image.
