Embodiment Construction

[0017] refer to figure 1 As shown, an embodiment of the image stabilizer of the present invention includes: a signal interface unit 910 , a dynamic control unit 911 and a resolution conversion unit 912 .

[0018] The signal interface unit 910 separates the camera image data into YUV to obtain YUV data, transmits the YUV data to the resolution conversion unit 912, detects and identifies the camera image data, and obtains the row points Htotalin of the camera image data , the total line number Vtotalin, the line synchronization Hs, the field synchronization Vs, the effective area data de and the camera input clock are transmitted to the dynamic control unit 911 . The dynamic control unit 911 generates the line points Htotalout and the total line number Vtotalout suitable for the output image resolution based on the number of line points transmitted by the signal interface unit 910, the total number of lines, the camera input clock and its own operating clock, and the effective ...

Abstract

The invention provides an image stabilizer, which is connected with image acquisition equipment. The image stabilizer comprises a signal interface unit, a dynamic control unit and a resolution conversion unit, wherein the signal interface unit extracts YUV data on the basis of the image data of the camera and generates the number of line points, the number of total lines, line synchronization, field synchronization, effective area data and camera input clock; according to the number of line points, the number of total lines and the camera input clock, which are generated by the signal interface unit, and the working clock of the dynamic control unit, the dynamic control unit generates the number of line points and the number of total lines, which adapt to the resolution of the outputted image; and according to the number of line points, the number of total lines and the effective area data, which are transmitted based on the dynamic control unit, and the YUV data transmitted by the signal interface unit, the resolution conversion unit generates the outputted image with a new image resolution. The image stabilizer can regulate the image acquired by the image acquisition equipment to provide the image of which the resolution is stable and can be regulated.

Description

technical field [0001] The invention relates to image control technology, in particular to an image stabilizer. Background technique [0002] At present, with the development of multimedia technology, the resulting various image acquisition devices have greatly enriched people's daily life. In some multimedia applications, it is often necessary to save the image obtained by the image acquisition device, or use the image as a material for secondary use, for example, as a static / dynamic background of a human-computer interaction interface in a digital TV. [0003] However, when the ambient illuminance of the image acquisition device changes, its output frame rate will also change, so that its image resolution will also change accordingly, resulting in unstable images. Contents of the invention [0004] The problem solved by the invention is that when the ambient illumination of the existing image acquisition equipment changes, the output image will be unstable. [0005] In...
