A method for dual-camera-based imaging, wherein the dual cameras comprise a wide-angle camera and a telephoto camera, and the method comprises: acquiring (S101) a first image shot by the wide-angle camera and a second image shot by the telephoto camera simultaneously; cropping (S102) the first image according to a target region of the first image to acquire a third image, wherein the target region is preset, the target region is a first part of the first image which takes a center of the first image as a center of the target region and spans a range determined according to at least one of the following: an angle of field of view of the wide-angle camera, a resolution of the wide-angle camera, or the ambient light luminance; determining (S103) depth information of the third image according to the third image and the second image; and performing (S104) blurring processing on the third image according to the depth information, to obtain a fourth image, wherein before cropping the first image according to the target region of the first image to acquire the third image, the method further comprises: determining a distribution region of the first image having a same view as that of the second image, wherein cropping the first image according to the target region of the first image to acquire the third image comprises: cropping the first image to obtain an intersection of the first part of the first image corresponding to the target region and a second part of the first image corresponding to the distribution region as the third image. acquiring (S101) a first image shot by the wide-angle camera and a second image shot by the telephoto camera simultaneously; cropping (S102) the first image according to a target region of the first image to acquire a third image, wherein the target region is preset, the target region is a first part of the first image which takes a center of the first image as a center of the target region and spans a range determined according to at least one of the following: an angle of field of view of the wide-angle camera, a resolution of the wide-angle camera, or the ambient light luminance; determining (S103) depth information of the third image according to the third image and the second image; and performing (S104) blurring processing on the third image according to the depth information, to obtain a fourth image, wherein before cropping the first image according to the target region of the first image to acquire the third image, the method further comprises: determining a distribution region of the first image having a same view as that of the second image, wherein cropping the first image according to the target region of the first image to acquire the third image comprises: cropping the first image to obtain an intersection of the first part of the first image corresponding to the target region and a second part of the first image corresponding to the distribution region as the third image. determining a distribution region of the first image having a same view as that of the second image, wherein cropping the first image according to the target region of the first image to acquire the third image comprises: cropping the first image to obtain an intersection of the first part of the first image corresponding to the target region and a second part of the first image corresponding to the distribution region as the third image. <EOS>
