Embodiment 1

[0035] figure 1 It is a flow chart of the image processing method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of reducing the size of the photographed object. This method can be executed by an electronic device with a camera, and the camera can be a front camera or Rear cameras, electronic devices such as smart phones, tablet computers, smart wearable devices, etc., the method specifically includes the following steps:

[0036] Step 110: Divide the first frame of picture according to the preset reduction ratio to obtain multiple comparison areas.

[0037] The first frame picture is a frame picture that needs to be reduced. In one implementation, the user activates the camera function of the terminal, the user switches the camera to the front camera (or the rear camera) through the camera switch button, and the image acquired by the front camera is displayed on the screen. When the frame picture that the user expects to ta...

Embodiment 2

[0065] The embodiment of the present invention also provides an image processing method, as a further description of Embodiment 1, as Figure 4 As shown, before step 110, dividing the first frame according to the preset reduction ratio to obtain a plurality of comparison areas, the method further includes:

[0066] Step 100, receiving a preset reduction ratio input by a user.

[0067] The terminal displays a preset reduction ratio input interface, and receives the preset reduction ratio input by the user in the interface.

[0068] The preset reduction ratio input interface may be, but not limited to, an interactive interface such as a slide bar, an addition and subtraction button, or a text box.

[0069] The sliding bar or the addition and subtraction button interface can provide users with a preset number of optional values, for example, provide 10 optional values, which are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0; Another example provides 4 optional values, 0.25, ...

Embodiment 3

[0109] An embodiment of the present invention also provides an image processing device for implementing the above method, the device is located in a terminal, such as Figure 10 As shown, the device includes:

[0110] A comparison area division unit 11, configured to divide the first frame of pictures according to a preset reduction ratio to obtain a plurality of comparison areas;

[0111] A comparison position information determination unit 12, configured to determine the comparison position information of each comparison area according to the first position information of each comparison area divided by the comparison area dividing unit 11 in the first frame picture, the The comparison position information is used to indicate the position of the corresponding comparison area in the target frame picture.

[0112] The output unit 13 is configured to output the position prompt information corresponding to each comparison area according to the comparison position information of...

Abstract

The invention discloses an image processing method and an apparatus. The method includes: dividing a first frame picture according to a preset reduction scale and obtaining a plurality of contrast areas; determining contrast position information of each contrast area according to first position information of each comparison area in the first frame picture; outputting position prompting information corresponding to each contrast area according to the contrast position information of each contrast area; determining a second frame picture to be a target frame picture corresponding to the contrast area if an obtained image in a target area of the second frame picture is in accordance with an image of one contrast area in the plurality of contrast areas; splicing a plurality of obtained target frame pictures and obtaining a combined frame picture when obtaining the target frame picture corresponding to each contrast area; and reducing the combined frame picture according to the preset reduction scale and obtaining a result frame picture. According to the image processing method and the apparatus, the area of faces occupied in the photos can be reduced, and the selfie cost is lowered.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image processing method and device. Background technique [0002] With the development of the camera function of electronic devices, the Selfie function has been widely popularized. For example, in a scenic area, tourists can be seen taking selfies with their mobile phones, and the background of the photo is the scenery behind them. [0003] Due to the limited length of the user's arm, the proportion of the user's face in the photo is relatively large. In order to reduce the proportion of the user's face in the photo, the prior art provides a selfie stick as an auxiliary camera device to increase the distance between the electronic device and the human face, thereby reducing the area occupied by the human face in the photo. [0004] However, when using a selfie stick to take a selfie, the user needs to purchase an additional selfie stick, resulting ...
