[0005] As we all know, when using the above-mentioned network camera to obtain image information and display it on the screen, if the image is full screen, you cannot receive any other text messages from the screen. If you need to receive other information from the screen, you need to shrink the video or adjust the size To minimize, so that users can not simultaneously browse video images and read text messages, resulting in great inconvenience

Embodiment Construction
[0025] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] The invention discloses a method and a device for loading additional information on a display image of a network camera terminal. The additional information can be information such as network advertisements, real-time news, instant messages or notices.
[0027] Such as figure 1 As shown, the network camera device includes: a camera 100 , an image encoding module 101 , a network processing module 102 , a control module 103 and a font and format conversion module 104 .
[0028] Wherein, the camera 100 directly outputs digital video signals as a video source;
[0029] Image processing module 101, used for digital video image signal reception, video image format conversion, additional information superimposition, MPEG-4 encoding compression and other functions;
[0030] The network processing module 102 includes two functions (1) for ...

The invention discloses a method for loading additional information on a display image at the terminal of a network camera device, comprising the steps as follows: firstly, a video image request is transmitted to the network camera device by a user by a browser, then an image processing module obtains source image data taken before from a camera and carries out format conversion, next a control module judges the storage position of the additional information and converts the format of the additional information, the source image data and the additional information respectively obtained after format conversion are output after superimposing and compressing in the image processing module, and the output compressed image is input to the browser for displaying by a network processing module. The design not only increases the additional function of the network camera device, but also can receive text information under the condition of not switching interfaces by the user, thus not only notdelaying the monitoring to the video image by the user, but also being capable of reading necessary text information.
Description
technical field [0001] The present invention relates to a digital image system, in particular to a display method and device based on the digital image system. Background technique [0002] Network camera devices include: IP Camera or Webcam, etc., where IP Camera is an intelligent product with independent IP address and embedded operating system to realize network monitoring. The above network camera devices can be connected directly through LAN, DSL or wireless network adapter. Connect to the network. A general network camera device includes a lens, optical filter, image sensor, digital compression processing controller and embedded operating system. New network camera devices can also be equipped with other more advanced functions, such as motion detection functions and so on. [0003] The network camera device first collects images, which can be regarded as composed of light of different wavelengths, and then convert it into a photoelectric signal. These photoelectric ...
