Problems solved by technology
In the prior art, the method of improving the hardware structure or using software to synthesize multiple frames of pictures is usually used to prevent shaking and improve the clarity of the photo during the photographing process. However, the method of using hardware to prevent shaking and reduce the clarity of the picture will increase the hardware Production cost, in addition, its application on mobile terminals such as mobile phones and tablet computers is not mature, and the yield rate of production is low; while the method of using software to synthesize multiple frames of pictures to prevent shaking and reduce the clarity of pictures, there is an algorithm The synthesis speed is slow, and the synthesis effect is sometimes not ideal

The embodiment of the invention provides photographing method and device. The photographing method comprises the steps of receiving a photographing previewing instruction; acquiring an image frame acquired by a camera; calculating a focusing evaluation value of the image frame; adding the image frame to an image cache array to be stored; receiving an input photographing instruction; selecting a target image frame from the image cache array according to the focusing evaluation value of the image frame; outputting the target image frame as a photographed image. With the adoption of the method, the definition of a photo can be improved, and the jittering is prevented.
Description
technical field [0001] The invention relates to the technical field of photographing, in particular to a photographing method and device. Background technique [0002] With the continuous development of terminal technology, many mobile terminals now support high-definition photography, for example: a mobile phone with a camera function, a tablet computer with a camera function, a handheld computer with a camera function, and the like. The quality of photos taken has become one of the criteria for evaluating the performance of a mobile terminal, and the shake generated during photo shooting is an important factor affecting the clarity of photos, so various schemes have been proposed to prevent The resulting shaking reduces the sharpness of the picture. In the prior art, the method of improving the hardware structure or using software to synthesize multiple frames of pictures is usually used to prevent shaking and improve the clarity of the photo during the photographing proc...
