Embodiment 1
[0056] figure 2 It is a schematic diagram of an image display process provided by an embodiment of the present invention. The process includes the following steps:
[0057] S201: Receive an associated display operation from a user, where the current display area includes a plurality of first rectangular areas, and the screen of each connected channel is displayed in the corresponding first rectangular area.
[0058] The image display method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device can be a PC, a tablet computer, etc., or a network hard disk video recorder, NVR, or other image acquisition device.
[0059] In the electronic device, the display area is divided into a plurality of first rectangular areas in advance according to a preset rule, for example, the display area is divided into 4, 8, or 16 first rectangular areas. Such as figure 1 As shown, the display area is divided into 16 first rectangular areas. In ...
Embodiment 2
[0068] On the basis of the foregoing embodiment, in the embodiment of the present invention, if the channel corresponding to the associated display operation does not belong to the channel of the multi-camera, the method further includes:
[0069] The picture of the channel is displayed in the entire display area.
[0070] Also to figure 1 As an example, if the electronic device determines that the channel corresponding to the associated display operation is a normal camera IPC1, it will display the screen of the normal camera IPC1 as Figure 5 The style, that is, the picture of the ordinary camera IPC1 channel is displayed in the entire display area.
Embodiment 3
[0072] In order to determine the second rectangular area corresponding to each channel of the multi-camera, on the basis of the foregoing embodiments, in the embodiment of the present invention, before determining the second rectangular area corresponding to each channel of the multi-camera , The method further includes:
[0073] Send a configuration information query request to the multi-eye camera, and receive information about the number of channels returned by the multi-eye camera.
[0074] The electronic device may send a configuration information query request to the connected multi-lens camera. After receiving the configuration information query request, the multi-lens camera sends information about the number of its own channels to the electronic device. The electronic device divides the display area according to the number of channels of the multi-lens camera to obtain a plurality of second rectangular areas.

Abstract
The invention discloses an image display method and device. The image display method comprises the following steps: receiving an associated display operation of a user; judging whether a channel corresponding to the associated display operation belongs to a channel of a multi-view camera, and if so, determining a second rectangular area corresponding to each channel of the multi-view camera; and displaying a picture, corresponding to each channel, of the multi-view camera in each second rectangular area. According to the embodiment of the invention, after the associated display operation of the user is received, if the channel corresponding to the associated display operation belongs to the channel of the multi-view camera, the second rectangular area corresponding to each channel of the multi-view camera is determined, and the picture of each channel of the multi-view camera is displayed in the plurality of second rectangular areas. And at the moment, the displayed pictures are channel pictures of the multi-view camera, so that the relevance of picture display of the multi-view camera is improved.
Description
Technical field [0001] The present invention relates to the field of image processing technology, in particular to an image display method and device. Background technique [0002] At present, the display method of the network video recorder (NVR) preview screen is mainly to divide the display area into different rectangular areas. When an IPC is connected, the IPC screen is displayed in a rectangular area. These rectangular areas are generally All of them are divided into equal parts in the shape of "well", such as 4 divisions, 9 divisions, and 16 divisions. The screens in these rectangular areas can be swapped, such as swapping 1 screen and 4 screens, double-clicking the mouse to zoom in on a single channel screen, and so on. Such as figure 1 As shown, the display area is divided into 16, and the normal display mode displays the screens from IPC1 to IPC5 and the three screens of the multi-eye IPC in the corresponding rectangular area, namely, multi-eye IPC1.1, multi-eye IPC1.2...
