Embodiment 1

[0031] Embodiment 1: see figure 1 As shown, it is a flow chart of the image processing method in the embodiment of the present application, the method can be applied to an image processing device, and the image processing device can be an NVR or other types of devices, without limitation, the image The processing method may include the following steps:

[0032] Step 101, acquire an original image that needs to be processed as a screenshot, and the original image includes image attributes.

[0033] Exemplarily, obtaining the original image that needs to be processed as a screenshot may include but not limited to:

[0034] Mode 1: Screen out some video images from a video image collection (including multiple frames of video images) stored in a specified storage medium (such as a hard disk). For each screened video image, the image attribute corresponding to the video image is obtained, and the image attribute is added to the video image to obtain an original image.

Embodiment 2

[0063] Embodiment 2: After the IPC collects the video image, it sends the video image to the NVR through the network, and the NVR stores the video image in a designated storage medium. Since the NVR is connected to multiple IPCs, that is, the multiple IPCs all send video images to the NVR, therefore, the NVR stores the video images of the multiple IPCs in a designated storage medium.

[0064] In order to realize the screenshot process of video images, NVR needs to select some video images from a large number of video images in the specified storage medium, and add image attributes to these video images. That is to say, for unselected video images, image attributes may not be included, and for selected video images, image attributes may be included. The process of adding image attributes to video images will be described below in conjunction with specific embodiments.

[0065] see figure 2 Shown is the flow chart of image processing method, and this method may comprise the f...

Embodiment 3

[0084] Embodiment 3: When screenshot processing is required, the NVR can acquire the original image that needs to be screenshot processed from the designated buffer, and perform screenshot processing on the original image. The screenshot processing process will be described below in combination with specific embodiments. see Figure 4 Shown is a flow chart of the image processing method, including:

[0085] In step 401, the NVR acquires the original image that needs to be processed as a screenshot from the specified buffer. Exemplarily, the NVR can acquire the original image from a specified buffer according to the write index corresponding to the original image.

[0086] For example, referring to the above-mentioned embodiment, it is assumed that the write index includes write index 1, write index 2 and write index 3, write index 1 includes start position A1 and end position A2, write index 2 includes start position A3 and end position A4, write Index 3 includes a start po...

Abstract

The invention provides an image processing method, device and apparatus and the method can comprise the steps: obtaining an original image needing to be subjected to screenshot processing, wherein theoriginal image comprises image attributes; determining screenshot parameters corresponding to the original image according to the image attributes; converting the original image into a target image according to the screenshot parameters; and displaying the target image, and / or storing the target image. According to the technical scheme, a user is prevented from sending a large number of screenshot commands, and the use experience of the user can be improved.

Description

technical field [0001] The present application relates to the field of video technology, in particular to an image processing method, device and equipment. Background technique [0002] After the IPC (Internet Protocol Camera, network camera) collects the video image, it sends the video image to the NVR (Network Video Recorder, network hard disk recorder) through the network, and the NVR stores the video image in the specified storage medium (such as hard disk, etc.) . Usually, the IPC will send a large number of video images to the NVR, and the NVR will store a large number of video images in a designated storage medium. [0003] In some application scenarios, NVR needs to select some video images from a large number of video images in the specified storage medium, and convert the format of some video images to obtain the target video image, and then, NVR displays or stores the target video image. This process can be It is called the screenshot process of video image. ...
