Abstract

The invention provides a preview image processing method and device, a camera device and a readable storage medium. The method is applied to the camera device and comprises the steps that a reference preview image collected by the camera device is obtained, and the reference preview image comprises a shooting body; determining position information of a shooting background in the reference preview image in the reference preview image; determining the relative movement speed of the shooting main body relative to the camera device; if the relative movement speed is smaller than a first threshold value, and if the time interval between the acquisition of the preview image to be processed and the acquisition of the reference preview image is smaller than a first preset time interval, performing blurring processing on an image area indicated by the position information in the preview image to be processed when the preview image to be processed acquired by the camera device subsequently is acquired. According to the invention, the blurring processing of the preview image can be realized on the premise that the data processing amount of the camera device is prevented from being too large.

Description

technical field

[0001] The present application belongs to the field of image processing, and in particular relates to a preview image processing method, a preview image processing device, a camera device and a computer-readable storage medium. Background technique

[0002] At present, when we use a camera device (such as a smart phone) to capture a preview image, we sometimes hope that the preview image can present a blurred background effect. At present, a commonly used background blurring method is: detecting a subject in an image to obtain location information of the subject, and then performing blurring processing on an image area outside the subject.

[0003] The frame rate of the preview image captured by the camera device is about 24 frames / s. Therefore, if the camera device performs background blurring processing on each frame of the preview image, it will undoubtedly increase the data processing capacity of the camera device, thereby making the camera device There ...
