Focusing method, focusing device and photographing machine

The embodiment of the invention discloses a focusing method, a focusing device and a photographing machine. The focusing method comprises the following steps: receiving a focusing success signal of afocusing system, and acquiring an image; performing image processing; if the image is not clear, controlling the focusing system to focus again; and if the image is clear, storing the image. Comparedwith the prior art, according to the embodiment of the invention, whether the successfully focused image is clear or not can be judged in time, and for an unclear image, the focusing system is controlled to focus again so as to obtain a new image, so that the definition of the image stored in the embodiment of the invention is relatively high, the focusing success rate is improved, and the photographing machine can photograph the clear image. 本发明实施例公开了一种对焦方法、对焦装置和拍照机。对焦方法包括：接收对焦系统对焦成功的信号，并获取图像；进行图像处理；若所述图像不清晰，则控制所述对焦系统重新对焦；若所述图像清晰，则储存所述图像。与现有技术相比，本发明实施例能够及时判断出对焦成功获取的图像是否清晰，对于不清晰的图像，本发明实施例控制对焦系统重新对焦，从而获取新的图像，因此，本发明实施例存储
