Embodiment Construction

[0018] The specific implementations of the method and device for partially enlarging a displayed image provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0019] refer to figure 1 as shown, figure 1 It is a flow chart of a local zoom-in method for displaying an image in an embodiment, including the following steps:

[0020] S10, acquiring partial images arranged on the splicing wall after video signal processing;

[0021] The above steps can be executed by a video signal processor of a display device such as a video wall, where the video signal processor is a video signal processor of a display device corresponding to a displayed image. The video signal processor can identify the image to be enlarged (that is, the partial image) framed by the user through its input device (such as a mouse, etc.).

[0022] S20, in the process of enlarging the partial image, repairing the details in the process of enlarging the im...

Abstract

The present invention relates to a method and an apparatus for partially magnifying a display image. The method for partially magnifying the display image comprises the following steps: obtaining a partial image laid out on a video wall and processed by the video signal; during the picture magnification of the partial image, repairing details during the picture magnification through a pre-stored weight coefficient to obtain a magnified image, wherein the weight coefficient is an artificial neural network weight coefficient obtained by learning a large number of pictures; displaying the magnified image in the form of a window next to a mouse frame selection area, and placing the magnified image on the next window of the mouse window. According to the method and the apparatus for partially magnifying the display image provided by the present invention, the magnified image can accurately represent each detail of the partial image, the corresponding magnification effect is effectively improved, and the display effect of the magnified partial image can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for partially enlarging a displayed image. Background technique [0002] Display devices such as large-screen splicing walls often need to be connected to the images captured by the camera for corresponding monitoring. During the monitoring process, when the details need to be checked, the user will freeze the picture frame and zoom in on the partial image for viewing. However, in the traditional solution, the partial enlargement of the image displayed by the display device is to use the more commonly used difference amplification method. This method does not make the details clearer after the image is enlarged, and it is easy to make the local image enlarged. The display effect is poor. Contents of the invention [0003] Based on this, it is necessary to provide a partial zoom-in method and device for displaying an image in order to solve the tech...
