Embodiment 1

[0032] figure 1 A flow chart showing the implementation of the method for realizing the depth-of-field effect in the mobile terminal provided by Embodiment 1 of the present invention is described in detail as follows:

[0033] In S101, a preview image to be captured is collected, and the preview image includes a character area and a background area;

[0034] In this embodiment, in order to let the user experience the depth-of-field effect in time, before S101, it may further include: outputting prompt information whether to enable the depth-of-field effect when receiving information that the user is shooting.

[0035] In S102, extract the person information in the preview image;

[0036] In this embodiment, S102 may be: extracting a histogram of oriented gradient (HOG) feature of the person in the preview image, specifically, extracting the HOG feature in the preview image, combining the HOG feature with The pre-established positive sample library is compared with the negati...

Embodiment 2

[0042] figure 2 A structural diagram of the mobile terminal provided by Embodiment 2 of the present invention is shown, and for convenience of description, only parts related to the embodiment of the present invention are shown.

[0043] The mobile terminal includes:

[0044] An acquisition unit 21, configured to acquire a preview image to be photographed, the preview image including a character area and a background area;

[0045] The extraction unit 22 is configured to extract the character information in the preview image; the calculation unit 23 is configured to calculate the area where the character is based on the character information, and calculate the area where the background is located based on the area where the character is located;

[0046] The blur processing unit 24 is configured to perform blur processing on the area where the background image is located.

[0047] Optionally, the extracting unit 22 specifically extracts the HOG features of the person in the...

Abstract

The invention relates to the technical field of communication and provides an effect of depth of field achieving method for a mobile terminal and the mobile terminal. The effect of depth of field achieving method for the mobile terminal comprises the following steps: collecting to-be-shot preview images which comprises a character region and a background region, extracting character information of the preview images, according to the character information, calculating the region where the character is located, according to the region where the character is located, calculating the region where the background is located, and conducting obscuring processing on the region where a background image is located. Due to the fact that the effect of depth of field achieving method for the mobile terminal and the mobile terminal are adopted, in the shooting process of the mobile terminal, a character position is automatically identified, a to-be-shot main character is highlighted, the background is obscured, the effect of depth of field is achieved, the mobile terminal facilitates a user shooting better photos, and user viscosity is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for realizing a depth-of-field effect in a mobile terminal and the mobile terminal. Background technique [0002] With the development of mobile terminal technology, mobile terminals have been widely popularized and gradually become an indispensable portable device in people's lives. In order to continuously meet people's needs, mobile terminals have more and more functions. Among many functions, mobile terminals The photographing function of the mobile terminal has also been widely used, and more and more people are used to using mobile terminal cameras to shoot people and scenes around them anytime and anywhere. However, the cameras on mobile terminals generally use digital zoom, which cannot achieve the depth of field on SLR cameras Effect. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a m...
