Abstract:
A method and a device for generating a blurred image, and a mobile terminal are provided. The method includes the followings. According to preview image data acquired via two rear cameras of a dual-camera device, first depth-of-field information for a foreground region and second depth-of-field information for a background region in a current preview image are determined. In addition, a basic value of a blurring degree is acquired according to the first depth-of-field information and the second depth-of-field information. Furthermore, Gaussian blur process is performed on the background region according to the basic value of the blurring degree to generate the blurred image.

Claim (Index 8):
A device for generating a blurred image, comprising:\n a non-transitory computer-readable medium having computer-executable instructions stored thereon, and an instruction execution system which is configured by the computer-executable instructions to implement: a determining module, configured to determine, according to preview image data acquired via two rear cameras of a dual-camera device, first depth-of-field information for a foreground region and second depth-of-field information for a background region in a current preview image; an acquiring module, configured to acquire a basic value of a blurring degree according to the first depth-of-field information and the second depth-of-field information, the basic value of the blurring degree being a reference value of the blurring degree; and a generating module, configured to perform Gaussian blur process on the background region according to the basic value of the blurring degree to generate the blurred image; wherein the generating module comprises: a determining unit, configured to determine a blurring coefficient for each pixel in the background region according to the basic value of the blurring degree and the second depth-of-field information for the background region; and a generating unit, configured to perform the Gaussian blur process on the background region according to the blurring coefficient for each pixel in the background region to generate the blurred image; wherein the determining unit is configured to calculate a multiplied value by multiplying the basic value of the blurring degree by the second depth-of-field information of each pixel in the background region, to obtain the blurring coefficient for each pixel in the background region.
