Problems solved by technology

When storing and displaying, it leads to a lot of waste of the memory data space of the buffer storage area of ​​​​the GUI layer and the bandwidth of reading the memory.
In view of the above problems, the existing technology usually reduces the waste rate through compression and other methods, but the above methods increase the complexity of hardware design

Embodiment

[0039] A continuous OSD storage and display method, comprising the following steps:

[0040] S100, collect OSD element information corresponding to the video window in the GUI graphics layer.

[0041] The GUI graphics layer is used to form the final display screen after being superimposed with the monitoring video screen.

[0042] The purpose of the OSD element is to convey information to the user. The expressed information includes, but is not limited to, prompt information, warning information, and control parameter value display information.

[0043] The OSD element may be a character type (Font-Based) or a bitmap type (Bit-Map). The principle of the character OSD is to divide the displayed content in the OSD into blocks according to a specific format (12×18, 12×16, etc.), such as numbers 0-9, letters a-z, commonly used brightness, contrast symbols, etc., and put the These contents are solidified in ROM or Flash, and only the corresponding index number is stored in the d...

Abstract

The invention discloses a continuous OSD storage and display method and device, and relates to the technical field of image processing. A continuous OSD storage and display method, comprising the steps of: collecting OSD element information corresponding to a video window in a GUI graphic layer; Combining the aforementioned OSD elements by type, and continuously arranging the OSD elements in a memory based on preset rules to store; Read The foregoing storage content is taken, and each OSD element is sent to the corresponding position of the corresponding divided window according to the window segmentation information of the current screen, and the synthesized image is displayed and output after being synthesized with the video layer. The invention can save the memory data space of the storage area for storing the GUI graphics layer, and reduce the bandwidth requirement for reading the memory.

Description

technical field [0001] The present invention relates to the technical field of image processing. Background technique [0002] In the field of surveillance, the final image displayed on the display is usually composed of multiple layers, such as the video layer from one or more surveillance cameras, and the corresponding graphical interface layer. These logical levels are synthesized according to preset rules to form the final display screen. Common synthesis methods such as overlaying the lower layer through the upper layer or alpha synthesis. [0003] see figure 1 As shown, a schematic diagram of displaying a monitoring video in the prior art is illustrated, including a Graphical User Interface (Graphical User Interface, GUI for short) layer 100 , a monitoring video 200 and a final display screen 300 . The monitoring video is a 4-channel video input, Image0 represents the video input display image of channel 0, Image1 represents the video input display image of channel ...
