Description

Video device and image configuration method thereof

A video recording device, in particular, a video recording device capable of automatically configuring images and a configuration method thereof.

The image capture device is used to capture image signals and then transmit the image signals to the video device. Then, the video device re-records the received video signal as an image file. That is to say, the conventional video recording device only records the received video signal and becomes an image file, and does not perform any processing on the image signal.

Moreover, when there are multiple image capturing devices, the image capturing devices respectively capture the image signals. Then, the video recording device separately records each video signal. In other words, when there are multiple image signals, the video device records each image signal to generate multiple image files.

That is to say, the video device generates a corresponding image file for each image signal. Therefore, when there are multiple image files, all the images will be visible when the user plays each image file at the same time. However, when this mode is slightly played back, the image files are not synchronized, which causes a problem that the user does not feel good.

In view of the above problems, the present invention provides a video recording apparatus capable of simultaneously recording and configuring a plurality of images in a video file.

An embodiment of the invention provides a video recording device, including: a plurality of image input ports, an image output port, and an image processing module. Each image input port is configured to connect to an image source to receive image signals. The image output port is configured to be connected to the display device to display a picture on the display device according to the output signal. The image processing module is connected to each image input port and image output port. The image processing module includes: a display control unit, a picture fusion unit, and a recording unit. The display control unit selects at least one first signal of each image signal according to the operation input, and mixes each of the first signals into an output signal. The picture fusion unit mixes the output signal and at least one second signal of each image signal into a video signal. The recording unit generates a video file according to the video signal.

An embodiment of the present invention provides an image configuration method for a video recording device, including: receiving a plurality of video signals. Selecting at least one first signal and at least one second signal in each image signal according to the operation input. Mix each of the first signals as an output signal. A screen is displayed on the display device according to the output signal. The second signal and the output signal are mixed into a video signal. And generate a video file based on the video signal.

According to the foregoing embodiment, the at least one first signal is selected and mixed into an output signal via the display control unit, and the output signal and the at least one second signal are mixed into a video signal via the picture fusion unit. In order to further generate video files for video signals. In this way, a plurality of image signals can be mixed into a video signal, thereby generating an image file having a mixture of multiple image signals. In this way, when the user plays the image file, the image corresponding to the plurality of image signals can be simultaneously viewed, so that the user can conveniently view the images simultaneously.

Referring to FIG. 1 , the video recording device 1 includes a plurality of image input ports 10 , an image output port 20 , and an image processing module 30 . The image processing module 30 is connected between each of the image input ports 10 and the image output ports 20 .

Each of the image input ports 10 is connected to each of the image sources 101 to receive image signals from the respective image sources 101 (step S01 of FIG. 2). That is to say, each image source 101 can be an output interface of the image signal.

In an embodiment, the image source 101 can be a computer, a notebook computer, a tablet computer, a smart phone, a camera, a remote audio and video device, an electronic whiteboard, a projector, a wireless projection device, a microphone and a sound amplification system, or the like. The output interface of the device for image signal is not limited by the present invention.

The image output port 20 is connected to the display device 201. The display device 201 can display a picture according to the output signal.

In one embodiment, the display device 201 can be a television, a computer, a notebook computer, a tablet computer, a smart phone, or other display device 201 having a display unit, and the present invention is not limited thereto.

The image processing module 30 includes a display control unit 31, a screen fusion unit 32, and a recording unit 33. The display control unit 31 selects at least one of the image signals as the first signal according to the operation input (step S02 of FIG. 2), and mixes the first signals into an output signal (step S03 of FIG. 2). The remaining image signals are the second signals (step S02 of FIG. 2). Then, the output signal is output from the image output port 20 to the display device 201 (step S04 of FIG. 2), so that the display device 201 can display the picture according to the output signal.

In one embodiment, the operation input can be operated by a button, a switch, a touch input, a remote control, or any other manner to select at least one of the image signals as the first signal.

The picture fusion unit 32 mixes the output signal and at least one of the second signals into a video signal (step S05 of FIG. 2). That is to say, after the display control unit 31 selects according to the operation input, each image signal can be divided into the first signal and the second signal. Then, the output signal corresponding to the first signal and the second signal are mixed into a video signal via the picture fusion unit 32.

For example, the display control unit 31 selects the video signal of channel 1 (CH1) as the first signal according to the operation input, and the remaining channels 2, 3 (CH2, CH3) are the second signal. Here, the display control unit 31 uses the first signal as an output signal, and outputs it to the display device 201 via the image output port 20 for the display device 201 to display a screen corresponding to the output signal (CH1). Then, the picture fusion unit 32 mixes the output signal (ie, the image signal of CH1) and the second signal (CH2, CH3) of the image signal into a video signal.

For example, the display control unit 31 selects the video signal of channel 1 and channel 2 (CH1, CH2) as the first signal according to the operation input, and the remaining channel 3 (CH3) is the second signal. Here, the display control unit 31 uses the first signal as an output signal, and outputs it to the display device 201 via the image output port 20 for the display device 201 to display a screen corresponding to the output signals (CH1, CH2). Then, the picture fusion unit 32 mixes the output signals (ie, the image signals of CH1 and CH2) and the second signal (CH3) of the image signals into a video signal.

In an embodiment, the first signal and the second signal are not repeated. That is to say, the image signal corresponding to the output signal is not duplicated with the image signal selected as the second signal.

The recording unit 33 generates a corresponding video file according to the video signal (step S06 of FIG. 2). That is to say, the recording unit 33 converts the video signal having each video signal (CH1 to CH3) into a video file.

In an embodiment, the video file can be played through the playback device, and the playback device can display the video image corresponding to each image signal via the display unit. In one embodiment, the video frame includes a main pane 2011 and a sub-pane 2012 (shown in FIG. 6). The main pane 2011 is used to display the main screen corresponding to the output signal. The sub-pane 2012 is used to display a sub-screen corresponding to each second signal. Therefore, the main pane 2011 in the display unit of the playback device displays the screen of the first signal (step S051 of FIG. 3) and the sub-pane 2012 can display the sub-picture of the second signal (step S052 of FIG. 3).

In one embodiment, the display control unit 31 selects a partial video signal as the first signal via the operation input, and also selects a partial video signal as the second signal. When any of the first signals overlaps with any of the second signals, the picture fusing unit 32 stops mixing the repeated first signals to the main pane 2011 (step S053 of FIG. 4). In other words, when the picture fusion unit 32 determines that there is a repetition between any one of the first signals and the second signal, the picture fusion unit 32 excludes the duplicated part of the first signal, so that the video file is in the file. The content corresponding to the display of the main pane 2011 does not have the same screen as the content displayed by the sub-pane 2012.

When the one of the first signals overlaps with any of the second signals, the picture fusion unit stops mixing the repeated second signals into the video signal (step S054 of FIG. 5).

In an embodiment, the display area of the main pane is larger than the display area of the sub-pane. The invention is not limited thereto. In some embodiments, the display area of the main pane is equal to the display area of the sub-pane.

This is illustrated by some examples, but the invention is not limited thereto. For example, please refer to FIG. 7. The video file has an image signal corresponding to CH1~CH3, and CH1 is a picture captured by the camera, CH2 is a brief message content, and CH3 is a remote picture. When the display control unit 31 selects the one-party conference mode according to the operation input, it selects the image signal of CH1 as the first signal, and selects CH2 as the second signal. Here, the main pane 2011 of the display device 201 displays a screen corresponding to CH1, and one of the sub-panes 2012 displays a screen corresponding to CH2. When the remote video conference mode is selected through the operation input, it selects the image signal of CH1 as the first signal, and selects CH2 and CH3 as the second signal. At this time, the video file correspondingly displays the picture of CH1 in the main pane 2011, and displays a picture corresponding to CH2 and CH3 (ie, the second signal) in one of the sub-panels, and the other sub-panel does not display the picture. . If the screen sharing mode is selected by the operation input, it selects the image signal of CH2 as the first signal, and selects CH1 and CH3 as the second signal. Therefore, the video file will display the screen of CH2 in the main pane 2011, and the screens of CH1 and CH3 will be displayed in the second pane 2012 respectively. If the first composite mode is selected if there is an operation input, it selects the image signals of CH1 and CH2 as the first signal, and selects CH2 and CH3 as the second signals. Here, the video file will display the pictures of CH1 and CH2 in the main pane 2011, and one of the sub-panels 2012 displays the picture of CH3. If the second composite mode is selected by operating the input, it selects the image signals of CH1 and CH2 as the first signal, and selects CH2 and CH3 as the second signals. Here, the video file will display the picture of CH1 in the main pane 2011, and one of the two sub-panels 2012 displays the picture of CH2, and the other sub-pane 2012 displays the picture of CH3. If the third composite mode is selected by operating the input, it selects the image signals of CH1 and CH2 as the first signal, and selects CH2 and CH3 as the second signals. Here, the video file will display the screen of CH2 in the main pane 2011, and one of the two sub-panels 2012 displays the screen of CH3, and the other sub-pane 2012 displays the screen of CH1. That is to say, the first signal and the second signal configuration can be displayed in the main pane 2011 or the sub-pane 2012 according to the comparison table 311 set in FIG.

Here, the display control unit 31 can display each video signal in the main pane 2011 or the sub-pane 2012 according to the comparison table 311. In other words, the configuration of the display screens of the main pane 2011 and the sub-pane 2012 in the various recording modes is set in the comparison table 311. In an embodiment, the comparison table 311 can be stored in the display control unit 31. However, the present invention is not limited thereto. In some embodiments, the comparison table 311 can also be stored in the storage unit (not shown).

According to the above embodiment, at least one first signal is selected and mixed into an output signal via the display control unit 31, and the output signal and the at least one second signal are mixed into a video signal via the picture fusion unit 32. In order to further generate video files for video signals. In this way, a plurality of image signals can be mixed into a video signal, thereby generating an image file having a plurality of image signals mixed. Therefore, when the user plays the image file, the image corresponding to the plurality of image signals can be simultaneously viewed, and the images in the image file can also be switched according to the switching between the first signal and the second signal, which is convenient for the user.
