[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] Please refer to Figure 1 , which is a flow chart of a method for independently adjusting video display content in a first embodiment of the present invention. The method for independently adjusting video display content provided by the embodiment of the present invention specifically includes the following steps.

[0051] Step S101: Copy the first video being recorded to obtain a second video. In this embodiment, after the contact image sensor (CIS) inputs the raw data (RAW data) into the system on chip (SOC), the image signal processor (ISP) copies the recorded video information to obtain two copies of the video data, the first video and the second video, which are exactly the same.

[0052] Step S102, stores the first video in a preset first buffer area, and stores the second video in a preset second buffer area. In the present application, the present application adopts two copies of the video, that is, a dual-stream method for processing. Specifically, a SOC with a dual-stream processing function is adopted, which can process the first video and the second video at the same time. The double data rate synchronous dynamic random access memory (Double Data Rate, DDR) is divided into two groups of cache areas, a first cache area and a second cache area. The first cache area and the second cache area are independent. Among them, the first cache area is used for the original video directly obtained by the codec (COder-DECoder, CODEC), and the second cache area is used to store the video to be processed that is scaled and moved according to user instructions.

[0053] In some feasible embodiments, the first buffer area and the second buffer area are of the same size. The first video is stored in the preset first buffer area, and the second video is stored in the preset second buffer area, which is determined according to actual application. In other feasible embodiments, the first buffer area and the second buffer area are of different sizes. The first video is stored in the preset first buffer area, and the second video is stored in the preset second buffer area, which is determined according to actual needs.

[0054] Step S103, when a video display adjustment instruction is obtained, the second video is adjusted according to the video adjustment instruction to obtain a third video, and the third video is displayed on the display device. In this embodiment, the video display adjustment instruction includes any one or more of scaling and moving. In this embodiment, when the video is displayed on the display interface, it does not affect the storage of the original video, so the second video is adjusted accordingly according to the user adjustment instruction obtained as the third video. For the video adjustment steps, please refer to steps S1031 to S1037, and steps S1032 to S1038.

[0055] In step S104, when a video playback instruction is received, the first video stored in the first buffer area is displayed on the display device. In this embodiment, when the video is played back, the first video stored in the first buffer area is displayed. The first video is the original video, recording the original perspective of the video capture device. This ensures the authenticity of the video content.

[0056] The first video being recorded is copied to obtain a second video; the first video is stored in a preset first buffer area, and the second video is stored in a preset second buffer area; when a video display adjustment instruction is obtained, the second video is adjusted according to the video adjustment instruction to obtain a third video, and the third video is displayed on the display device; when a video playback instruction is obtained, the first video stored in the first buffer area is displayed on the display device. This ensures that the video recorded content can be restored to the original field of view, and the displayed image can be adjusted according to the user's preferences during use, ensuring user comfort.

[0057] Please refer to Figure 2 , which is a sub-flowchart of the method for independently adjusting video display content in the second embodiment of the present invention. The method for independently adjusting video display content provided by the second embodiment differs from the method for independently adjusting video display content provided by the first embodiment in that, after storing the first video in the preset first buffer area and the second video in the preset second buffer area, the method for independently adjusting video display content provided by the second embodiment further includes the following steps.

[0058] Step S201: When the video processing capability of the image processor is greater than or equal to a preset standard, the first video and the second video are processed simultaneously to obtain a first cached video and a second cached video.

[0059] In step S202 , the first cached video is stored in a preset first cache area and the second cached video is stored in a preset second cache area.

[0060] In this embodiment, different ISPs have different video processing capabilities. When the image processor has a strong video processing capability and can process multiple views simultaneously, the image quality processing of the two videos is performed simultaneously, that is, the first video, i.e., the original video, is processed accordingly, and the second video is also processed according to display parameters such as brightness and contrast as required. The processed two images are stored in the designated cache area at the same time.

[0061] Please refer to Figure 3, which is a sub-flowchart of the method for independently adjusting video display content in the third embodiment of the present invention. The method for independently adjusting video display content provided in the third embodiment differs from the method for independently adjusting video display content provided in the first embodiment in that, after storing the first video in the preset first buffer area and the second video in the preset second buffer area, the method for independently adjusting video display content provided in the third embodiment further includes the following steps.

[0062] Step S301 : When the video processing capability of the image processor is less than a preset standard, the first video and the second video are processed respectively to obtain a first cached video and a second cached video.

[0063] Step S302: storing the first cached video in a preset first cache area and storing the second cached video in a preset second cache area.

[0064] In this embodiment, different ISPs have different video processing capabilities. When the image processor's video processing capabilities are weak and unable to process multiple views simultaneously, the image quality of the two video channels is processed separately. The first video is processed first. Generally, the first video requires less processing and is processed faster. After the first video is processed, the second video is processed, and the brightness and contrast of the second video are manipulated to achieve the user's preferred parameters. The two processed images are stored sequentially in the designated cache area.

[0065] Please refer to Figure 4 , which is a flowchart of step S103 in the first embodiment of the present invention, wherein step S103, when a video display adjustment instruction is obtained, the second video is adjusted according to the video adjustment instruction to obtain a third video, specifically including the following steps.

[0066] In step S1031, when the video display adjustment instruction is to zoom first and then move, a first center point specified by the user is obtained. In this embodiment, the second video stored in the second buffer area is processed. Specifically, the received signal area is magnified with the point as the center. First, a designated area input by the user is obtained. This area can be the area captured by a finger touching the touch screen, the location of keyboard input coordinates, etc. The center point of the area to be magnified is obtained according to a preset area center point selection method.

[0067] Step S1033: Obtain a first video processing area based on the first center point. In this embodiment, a certain area around the first center point is demarcated according to a preset rule to obtain the first video processing area, which can be a circle or other preset shapes.

[0068] Step S1035: zoom in or out the first video processing area to obtain a second video processing area. In this embodiment, the second video processing area is obtained by zooming in or out the entire video content at the center point according to the obtained magnification factor, and the second video processing area is displayed on the display device.

[0069] Step S1037: Move the second video processing area to obtain a third video. In this embodiment, the amplified second video processing area is moved up, down, left, and right, and the area where it finally stops is displayed on the display device as the third video.

[0070] Please refer to Figure 5 , which is a flowchart of step S103 in the first embodiment of the present invention, wherein step S103, when a video display adjustment instruction is obtained, the second video is adjusted according to the video adjustment instruction to obtain a third video, specifically including the following steps.

[0071] In step S1032, when the video display adjustment instruction is to move first and then zoom, a second center point specified by the user is obtained. In this embodiment, the second video stored in the second buffer area is processed. Specifically, the received signal area is magnified with the point as the center. First, a designated area input by the user is obtained. This area can be the area captured by a finger touching the touch screen, the location of keyboard input coordinates, etc. The center point of the area to be magnified is obtained using a preset area center point selection method.

[0072] Step S1034: Obtain a third video processing area based on the second center point. The third video processing area is obtained by demarcating a certain area around the second center point according to a preset rule. Specifically, the third video processing area can be a circle or other preset shapes.

[0073] Step S1036: Move the third video processing area to obtain a fourth video processing area. In this embodiment, the fourth video processing area is obtained by moving the entire content displayed on the video around the center point according to the obtained magnification.

[0074] Step S1038: zoom in or out the fourth video processing area to obtain a third video. In this embodiment, the third video is obtained by zooming in or out the entire content of the video display at the center point according to the obtained magnification factor, and the third video is displayed on the display device.

[0075] Please refer to Figure 6, which is a sub-flowchart of the method for independently adjusting video display content in the fourth embodiment of the present invention. The method for independently adjusting video display content provided by the fourth embodiment differs from the method for independently adjusting video display content provided by the first embodiment in that the method for independently adjusting video display content provided by the fourth embodiment further includes the following steps.

[0076] Step S701: Record video adjustment instructions.

[0077] Step S702: When the device is turned on again, the second video is directly adjusted according to the video adjustment instruction to obtain a third video, and the third video is displayed through the display device.

[0078] In this embodiment, the second video is an independent resource used to independently process real-time zooming, region selection, and field of view movement. In actual applications, various user adjustment parameters for image processing are obtained through an Application Program Interface (API) and recorded in a Serial Peripheral Interface (SPI) flash memory. When the video display device is restarted, the corresponding parameters can be directly read from the SPI flash memory and displayed on the third video device.

[0079] The above embodiment does not require any additional hardware costs; a standard SOC or ISP can meet the technical requirements of this solution. Furthermore, it utilizes existing techniques for processing multiple videos simultaneously, preserving the original video while enabling user-friendly adjustments during use. This perfectly solves the existing problem of being unable to simultaneously store the original video and the video with modified parameters during video recording.

[0080] The embodiment of the present invention further provides a video display device 800, please refer to Figure 7 The video display device 800 includes a recording module 810 , a cache module 820 , a video adjustment module 830 and a video review module 840 .

[0081] Specifically, the recording module 810 is used to copy the first video being recorded to obtain a second video. The cache module 820 is used to store the first video in a preset first cache area and the second video in a preset second cache area. The video adjustment module 830 is used to, when a video display adjustment instruction is obtained, adjust the second video according to the video adjustment instruction to obtain a third video, and display the third video on a display device. The video review module 840 is used to, when a video review instruction is obtained, display the first video stored in the first cache area on a display device.
