Image processing method and device

The invention provides an image processing method and device. The method comprises the steps that after n first images shot by a main camera and secondary images shot by a secondary camera are acquired, synthesis and noise reduction are conducted according to the n first images to obtain a main image; and depth information of the main image is calculated according to a main image and a secondary image, so that the main image is subjected to blurring processing according to the depth information of the main image to obtain a needed second image. On one hand, the imaging effect of the imaged picture is improved, on the other hand, the accuracy of the depth information is improved, therefore, the image processing effect is good, and the technical problem that in the prior art, the effect of an image obtained after blurring processing is poor is solved.
