Ring image compression and decompression method, device and equipment

Abstract

The invention discloses a method for compressing and decompressing a ring image, which comprises determining a reference data point in the ring image during the compression process, obtaining and saving characteristic data of the reference data point; The relative position between adjacent data points, determine the relative data of each data point relative to the previous data point and save it; during the decompression process, determine the starting position of the ring image according to the characteristic data of the reference data point; from the starting position At first, according to the relative data of each data point relative to the previous data point, the image of each data point is sequentially drawn to obtain a circular image. The invention is specially used for extracting the ring image, reduces the amount of data extracted during image compression, and improves the decompression speed during subsequent decompression, so that the user feels better. The invention also discloses a device, equipment and computer-readable storage medium based on the above method.

Description

technical field [0001] The invention relates to the technical field of data compression, in particular to a ring image compression and decompression method. The present invention also relates to a device, device and computer-readable storage medium based on the above method. Background technique [0002] In order to provide a more user-friendly display interface, the UI user interface display of small systems has been effectively developed, such as smart watches. In such small systems, due to user needs, there will be many need to display ring images or corresponding UI ring animations. , such as step counting rings or other progress bars. Among them, the current data storage method of the ring image adopts a common image compression and decompression method such as png. [0003] Since the general png image decompression method needs to be applicable to various systems and scenarios, in order to achieve its versatility, various types of parameter data will be extracted dur...

Problems solved by technology

However, due to the size of the small embedded system, its memory and flash are small, and the speed of the CPU is not high enough. In this case, if the png format image compression method is used, it will take up a lot of flash space and affect the small embedded Other functions of the system; and in the subsequent decompression process of the ring image, the algorithm will be complicated and the calculation will be large due to the large amount of data and the large number of data types, and the speed of the cpu of the small embedded system is higher than that of the ordinary large The system is relatively slow, so such a large amount of data processing will make the decompression speed too slow, affecting the display speed of the ring image, and the user experience is poor
