If these multiple images are directly transmitted, it will cause a large amount of transmitted data and occupy a large transmission bandwidth.
[0004] In order to reduce the amount of data, image files are usually compressed, but the amount of data is still large after this compression, and the compression rate is very low

example 1
[0270] Such as Figure 8 As shown, this example provides an image information processing method, including multiple steps such as decompression, image conversion, encoding, caching, and compression. In some application scenarios, the decompression is unnecessary.
[0271] The decompression may include:
[0272] Read compressed files, for example, compressed files compressed using video compression technology in the aforementioned embodiments;
[0273] Decompression, here, the compressed file read for decompression, resulting in multiple images, in Figure 8 Image 1, Image 2, Image 3, etc. are displayed in .
[0274] If it is necessary to perform video compression on the above-mentioned files, then proceed to the next steps, such as encoding, caching and compression. In some embodiments, the image conversion may be an unnecessary step, for example, if the original stored image is a YUVA image, no image conversion is required.
[0275] The image conversion, encoding and cac...
example 2
[0291] Such as Figure 9 As shown, this example provides a method for processing image information, and the image information may include: image data of various images. The method may include:
[0292]read compressed files;
[0293] The compressed file is decompressed to obtain decompressed file 1, decompressed file 2 and decompressed file 3, which are not limited to 3 decompressed files in actual implementation.
[0294] The cache operation may include: a video file header, an image frame header, and cache data (the cache data may include: original image data).
[0298] Determine whether it is the last image, if not return the cache operation.
[0299] Image transformations can include:
[0300] The YUVA image is obtained by encoding the image frame;
[0301] Remove the blank component of the YUVA image to obtain a grayscale image;
[0302] Store raw image data, or, ...

Abstract
Embodiments of the present invention provide an image information processing method, a device, and a storage medium. The method comprises: determining key images and other ordinary images in a to-be-compressed YUVA image. The YUVA image comprises a luminance Y component, a first color difference U component, and a second color difference V component, a transparency A component, a first blank component, and a second blank component. The data amount of the Y component is equal to that of the A component. The sum of the data amounts of the U component and the first blank component is equal to half of the data amount of the A component. The sum of the data amounts of the V component and the second blank component is equal to half of the data amount of the A component. According to the key images and the ordinary images, the YUVA image is subject to video compression and a compressed file of the YUVA image is obtained.
Description
technical field [0001] The present invention relates to the field of information technology, in particular to an image information processing method and device, and a storage medium. Background technique [0002] Sequence frame refers to an image sequence composed of several images in order; sequence frame animation refers to the playback technology of playing each image one by one in sequence. [0003] Files for sequence frame animation usually consist of multiple images. If these multiple images are directly transmitted, problems such as a large amount of transmitted data and a large occupied transmission bandwidth will be caused. [0004] In order to reduce the amount of data, image files are usually compressed, but the amount of data is still large after this compression, and the compression rate is very low. Contents of the invention [0005] In view of this, the embodiments of the present invention expect to provide an image information processing method and device...
