IPC: H04N5/232
Filed: 2019-03-14
Abstract: Provided are a photographing method and apparatus. The method comprises: when a photographing operation is executed, collecting at least two frames of candidate image data; respectively extracting, from the at least two frames of candidate image data, at least two pieces of target area data, the blurring degrees of which meet a pre-set blurring condition, partial areas of which overlap, and areas where same are located matching each other; and splicing the target area data into target image data. Partial areas overlap, so that target area data can be spliced. The association between collected candidate image data is taken into consideration. Areas where the pieces of target area data match each other mean that the content integrity of a spliced image can be ensured. Suitable target area data is screened by means of a blurring condition, thereby ensuring the definition of spliced image data, reducing the impact caused by canceling out shaking, having no need to additionally configure independent devices and reducing the cost, and the splicing processing operation is simple, thus improving the processing speed and saving on the time consumed.

Abstract: The present application provides a communication method, comprising: determining a first transmission time, the first transmission time being the transmission time for transmitting on a secondary carrier within a target time period; determining a second transmission time according to the first transmission time, the second transmission time being the transmission time for transmitting on a primary carrier within the target time period, the sum of the SAR of the primary carrier and the secondary carrier in the target time period being less than or equal to an SAR threshold value. If the first transmission time is relatively long, it is necessary to reduce the transmission time of the primary carrier within the target time period so as to ensure that the total SAR value of the wireless device during the target time period does not exceed the specification; if the first transmission time is relatively short, then the transmission time of the primary carrier within the target time period can be increased, the premise being to ensure that the total SAR value of the wireless device within the target time period does not exceed the specification. Therefore the described solution can ensure that the SAR value of a wireless device which uses a plurality of carriers for communication does not exceed a specification, and furthermore also flexibly adjust the transmission time of the primary carrier.
