Embodiment 1

[0057]The embodiment of the present invention provides an image acquisition method, please refer to figure 1 , which is a schematic flowchart of Embodiment 1 of the image acquisition method provided by the embodiment of the present invention, as figure 1 As shown, the method includes the following steps:

[0058] S101. During the process of continuously acquiring images, detect a picture change between two adjacent frames of images.

[0059] In the embodiment of the present invention, it is possible to detect the picture change between two adjacent frames of images in the process of continuous image acquisition, in order to use the acquisition method for the currently acquired image according to the picture change between two adjacent frames of images. Quality is adjusted.

[0060] In a specific implementation process, by detecting the picture change between two adjacent frames of images, the current frame picture and the previous frame picture in the collected image can be ...

Embodiment 2

[0102] The embodiment of the present invention also provides an image acquisition method, please refer to figure 2 , which is a schematic flowchart of Embodiment 2 of the image acquisition method provided by the embodiment of the present invention, as figure 2 As shown, the method includes the following steps:

[0103] S201. During the process of continuously acquiring images, detect a picture change between two adjacent frames of images.

[0104] S202, whether there is a change between two adjacent frames of images, if yes, execute S203; if not, execute S204.

[0105] S203, whether the difference between two adjacent frames of images changes greatly, if yes, execute S205; if not, execute S206.

[0106] S204. Adjust the acquisition quality used for the currently acquired image to the lowest acquisition quality.

[0107] S205. Adjust the collection quality used for the currently collected image to the highest collection quality.

[0108] S206. Adjust the acquisition quali...

Abstract

The embodiment provides an image acquisition method and a device. On one hand, the image acquisition method comprises steps of: detecting frame change conditions between adjacent two frames of images in an image continuous acquisition process; then, according to the frame change conditions between adjacent two frames of images in an image continuous acquisition process, adjusting the acquisition quality of the current acquisition image; and finally, carrying out image acquisition by use of the acquisition quality obtained through the adjustment. Therefore, according the technical scheme provided by the embodiment, a problem of failure to meet different image acquisition requirements caused by the poorer flexibility caused by the use of fixed acquisition quality to acquire the image is solved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of communication technologies, in particular to an image acquisition method and device. [0003] 【Background technique】 [0004] At present, most of the image acquisition devices on the market are relatively traditional. Generally, the image acquisition quality of the images acquired by the image acquisition devices is set in advance, and the acquisition quality will not change during the image acquisition process. [0005] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0006] If the preset capture quality is high, the captured images will take up a lot of storage space, greatly shortening the image capture time; if the preset capture quality is low, the quality of the captured images will be poor, affecting image review and identification. Therefore, the use of fixed acquisition quality to acquire images in the ...
