Problems solved by technology

[0003] However, the first method needs to use dual cameras to calculate the depth information, which has a large amount of calculation and is unstable, and it is easy to make the image blurred; the second method is easily affected by factors such as illumination changes and object movement; the third method requires artificial operation, the human factor is large
Therefore, the effect of small depth of field images captured by the above three methods is poor

Abstract

The invention provides an image processing method and a terminal. The method comprises the steps that phase difference data of a target image which is currently collected are acquired; the phase difference data are used for reflecting distribution phase difference in the target image; according to the phase difference data, a defocus area and a focus area of the target image are determined; blur processing is carried out on the defocus area of the target image; and the focus area and the blurred defocus area of the target image are synthesized to acquire a small field depth image. According to the invention, the shooting effect of the small field depth image can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and a terminal. Background technique [0002] With the rapid development of terminal technology, there are more and more mobile terminals with a shooting function, such as digital cameras, mobile phones, and tablet computers. Due to the limitation of the size of the imaging device of the mobile terminal, it is difficult to use a large aperture and a telephoto lens, which makes it difficult to capture images with a small depth of field. In order to solve the above problems, the current common processing methods are as follows: Method 1. Use dual cameras for close-up shooting, extract the depth map and record the focus position, and perform defocus blur processing on the image area farther from the focus position. Image areas that are closer to the focus position are not defocused. The difference between method two and method one is tha...
