Embodiment 1

[0053] The embodiment of the present invention provides a method for generating video information, and the execution subject of the method may be a terminal or an image processing module in the terminal; in the embodiment of the present invention, the execution subject is the image processing module as an example for illustration. see figure 1 , where the method includes:

[0054] Step 101: The image processing module receives the image sent by the image sensor, and acquires the first receiving time of the image;

[0055] The image sensor collects an image, and sends the image to the image processing module; the image processing module receives the image sent by the image sensor, obtains the current time, and uses the current time as the first receiving time for the image processing module to receive the image.

[0056]Further, the image processing module determines whether the image is the first frame image of the video information; if the image is the first frame image of t...

Embodiment 2

[0065] The embodiment of the present invention provides a method for generating video information, and the execution subject of the method may be a terminal or an image processing module in the terminal; in the embodiment of the present invention, the execution subject is the image processing module as an example for illustration. see figure 2 , where the method includes:

[0066] Step 201: the image processing module receives the image sent by the image sensor, and acquires the first receiving time of the image;

[0067] The image sensor collects an image, and sends the image to the image processing module. The image processing module receives the image sent by the image sensor, obtains the current time, and uses the current time as the first receiving time for the image processing module to receive the image.

[0068] The image sensor may be a camera or a video camera, etc.; and the image sensor may be an image sensor in the terminal, or an image sensor included in other d...

Embodiment 3

[0128] An embodiment of the present invention provides a device for generating video information, and the device may be a terminal or an image processing module in a terminal; see Figure 3-1 , where the device includes:

[0129] The first acquiring module 301 is configured to receive the image sent by the image sensor, and acquire the first receiving time of the image;

[0130] The second acquiring module 302 is configured to acquire the first preset receiving time of the next frame image that is preset when the video information is generated;

[0131] The first determining module 303 is configured to determine whether to discard the image according to the first receiving time and the first preset receiving time;

[0132] The generating module 304 is configured to generate video information according to the image and the first receiving time if the image is not discarded.

[0133] Further, see Figure 3-2 , the device also includes:

[0134] The second determination modul...

Abstract

The invention discloses a method and a device for generating video information. The method and the device belong to the field of multimedia technology. The method comprises the steps of receiving an image which is transmitted from an image sensor by an image processing module, and acquiring first receiving time of the image; acquiring a first preset receiving time of a next image frame which is preset in generating video information and is closest to current time by the image processing module; determining whether to discard the image by the image processing module according to first receiving time and first preset receiving time; and if the image is not discarded, generating video information by the image processing module according to the image and the first receiving time. The device comprises a first acquiring module, a second acquiring module, a first determining module and a generating module. The method and the device provided by the invention have advantages of realizing no requirement for image buffering, reducing resource consumption and improving time coupling property of generated video information.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for generating video information. Background technique [0002] At present, most mobile phones have a camera and an image processing module. The camera is used to collect images, obtain images frame by frame, and transmit the images frame by frame to the image processing module in real time, and the image processing module receives the images sent by the camera in real time. image, and generate video information according to the time of receiving the image. [0003] Usually, the first frame rate of the image collected by the camera is generally higher than the second frame rate of the image processed by the image processing module, and the image processing module needs to discard a part of the images sent by the camera when generating video information. The process of generating video information by the image processing module can be as follows: the image...
