A method includes: receiving a first event, where the first event is used to trigger image quality adjustment of a splicing display; sending N reference pictures including a first reference picture to the splicing display in response to the first event; receiving a first photo obtained by photographing an entire display area of the splicing display when the splicing display displays the first reference picture in full screen as a whole; and generating a first image quality adjustment parameter and a second image quality adjustment parameter based on the first reference picture and the first photo, where the first image quality adjustment parameter and the second image quality adjustment parameter is used to adjust image quality of the first and second display respectively.

Image quality adjustment method and apparatus

A data processing method, apparatus, and system, where the method includes: receiving a data insertion request sent by service software, where the data insertion request includes a data record, and the data record includes an object type identifier, a field value, a field identifier, and an object instance identifier; generating a field index based on the object type identifier, the field value, and the object instance identifier; generating a relationship index based on the object type identifier; writing the data record to a database; and caching an index record and an operation for the index record into a cache apparatus, where the index record includes the relationship index and the field index. Using the foregoing solution, high-performance data processing of a flat-wide table is implemented.
