Abstract: A photographing method, including: obtaining a preview stream; detecting a movement speed of a photographed subject according to the preview stream; obtaining a first exposure time by shortening, according to the movement speed, an initial exposure time for preview frames in the preview stream, in response to determining that the movement speed is higher than a preset speed threshold; and capturing a picture based on the first exposure time.

Abstract: An image processing method is provided. The method includes: obtaining a to-be-processed image; extracting attribute information of the to-be-processed image; determining an image processing strategy corresponding to the to-be-processed image according to the attribute information; and obtaining a target image by processing the to-be-processed image according to the image processing strategy.

Abstract: According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor cause the processor to receive parameters for a partition range for a partition key associated with a table. The table may have a vertical table structure. The processor may generate an index of vertical table columns based on the received parameters for the partition range. The generated index may be a physical store for data from the table and may have a subset of rows of the table correlating to the partition range. The processor may receive a query having a predicate associated with the partition key associated with the table and, based on a determination that the predicate included in the received query is within a partition range for the generated index, the processor may execute the query using the generated index.
