Abstract

The invention discloses a background blurring method based on a depth of field, used for processing scene data collected by an electronic device, wherein the scene data comprises a scene main image. The background blurring method comprises the steps of processing the scene data to acquire image depth information of the scene main image; acquiring the most front point of the scene main image according to the image depth information; determining an area except the area adjoined with the most front point and with continuously variable depth to be a background part; acquiring background depth information of the background part; dividing the background part into at least one blurring area according to the background depth information, wherein the span of a depth range corresponding to each blurring area is positively correlated with the distance between the depth range and the most front point of the scene main image; determining a blurring degree of each blurring area, wherein the blurring degree of each blurring area is positively correlated with the corresponding depth; and blurring the background part. The invention also discloses a background blurring device based on the depth of field and the electronic device. According to the method and the devices provided by the invention, the blurring effect of the image can be more natural and closer to an optical out-of-focus effect.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a depth-of-field-based blurring method and device, and an electronic device. Background technique [0002] Existing background blurring techniques are not ideal. Contents of the invention [0003] Embodiments of the present invention provide a method for blurring a background based on a depth of field, a device for blurring a background based on a depth of field, and an electronic device.
