However, the method of determining the distance parameter from the first detection image in the present invention is not limited to the above.

If the device 100 includes the third image capture module 130, the control module 150 can also use the first detection image and the second image captured synchronously by the first image capture module 110 and the third image capture module 130.

If the device 100 also Including the third image capture module 130, the stream combination may also include a third image stream synchronously generated by the third image capture module 130 and the first image capture module.

In more detail, the stream combination generated by the imaging module 160 may also be an image stream including multiple frames, each frame in the stream combination may contain multiple pixel blocks, and all the frames in the stream combination include The size and quantity of the pixel blocks can be the same, as shown in "FIG. 4", the frame 400 includes 25 pixel blocks. Each pixel block of each frame in the stream combination contains a target image captured by a different image capture module (in this creation, the target image contained in the pixel block is also called an image frame), and Different pixel blocks of each frame in the stream combination are target images captured synchronously by each image capture module. In other words, since the image streams generated by each image capture module are synchronized, that is, the target images in the image streams generated by each image capture module are synchronized, so the imaging module 160 can separate the synchronized target images Added to different pixel blocks of the same frame in the stream combination.

Generally speaking, the position of the target image (image frame) of each video stream included in the stream combination is fixed in all the frames of the stream combination, that is, they are arranged at the same position in the frames of the stream combination The image frames included in the pixel block are target images (frames) at different times of the image stream generated by the same image capture module. For example, if the second target image captured by the second image capture module 124 is arranged in the pixel block 411 in the upper left corner of the frame 400, then in In all frames combined by the stream, the second target image captured by the second image capture module 124 is fixedly arranged in the pixel block 411 in the upper left corner.

What needs to be specially mentioned is that the position of the pixel block corresponding to the target image of each image stream in each frame of the stream combination can be determined according to the capture angle of each image stream, that is to say The imaging module 160 can determine the pixel block size of the target image captured by each image capture module in each frame of the stream combination according to the relative position of each image capture module in the device 100 or the module identification data. Location. For example, if the device 100 includes 25 image capture modules, it is assumed that according to the positions of the image capture modules in the device 100 from left to right, they are the second image capture module 124, ..., the second image Capture module 122, ..., first image capture module 110, ..., second image capture module 121, ..., second image capture module 123, then the second image capture module 124 captures The second target image can be arranged in the pixel block 411 in the upper left corner of the frame 400 combined by the stream, and the image arranged on the right side of the second image capture module 124 and adjacent to the second image capture module 124 The second target image in the image stream generated by the capture module can be arranged in the second pixel block 412 on the left of the first row of the frame 400, and so on, ..., captured by the first image capture module 110 The captured first target image can be arranged in the pixel block 433 in the center of the frame 400 combined by the stream, ..., arranged on the left side of the second image capture module 123 and adjacent to the second image capture module 123 The second target image in the image stream generated by the capture module can be arranged in the second pixel block 454 on the right side of the last column of the frame 400, and the second target image captured by the second image capture module 123 will be able to The pixel block 455 is arranged in the lower right corner of the stream combined frame 400 .

The communication module 170 can be electrically connected with the imaging module 160 and the display module 190, and can also be connected with external devices such as the display device 250 through wired and/or wireless communication technology, so as to make the device The 100 and the external device can transmit data or signals to each other, for example, combining and transmitting the stream generated by the imaging module 160 to the display device 250 , or receiving video and audio streams transmitted by other communication devices.

The display module 190 is electrically connected to the communication module 170 and can display the video and audio streams received by the communication module 170 .

The display device 250 can be connected with the communication module 170, and can receive the combination of streams transmitted by the communication module 170, and can display the first image stream in the received combination of streams, and specify one or more second video streams. The image capture module 120 can display the second image stream and/or the third image stream, and the display device 250 can also display all the image streams.

Next, an example is used to explain the operation process of this creation, and please refer to "Figure 5" for the flow chart of the immersive streaming video capture and imaging mentioned in this creation.

After the user of the device 100 activates the device 100, the first image capture module 110 can capture the first detection image including the shooting target 210 (step 510). In this embodiment, assuming that after the device 100 is activated, the control module 150 can generate detection signals at regular intervals, the first image capture module 110 can capture Take the first detection image once.

After the first image capture module 110 captures the first detection image, the control module 150 can generate a distance parameter according to the first detection image captured by the first image capture module 110 (step 520 ). In this embodiment, assuming that the distance parameter is the target distance, the control module 150 can determine the distance parameter according to Newton's method or by identifying the size of a specific object in the first detected image and comparing it with a pre-stored value to determine the distance parameter.

After the distance parameter is generated by the control module 150, the control module 150 can calculate the second image capture according to the generated distance parameter and the device distance between each second image capture module 120 and the first image capture module 110. Get the rotation angle of the module 120 (step 530), and control the rotation of each second image capture module 120 according to the calculated rotation angle of each second image capture module 120 (step 540). In this embodiment, it is assumed that the control module 150 can calculate the rotation angle of each second image capture module 120 through the trigonometric function of tan ^-1 (device distance/distance parameter) one by one, and control the rotation angle of each second image capture module 120 The module 120 rotates the angle of rotation toward the shooting target 210. If the image capture module is shown in "Fig. 3", the control module 150 can first calculate the rotation angle of the second image capture module 124 and then control the second image capture module. The set 124 rotates the calculated rotation angle counterclockwise. Then, the control module 150 can calculate the rotation angle of the second image capture module 122 and control the second image module 122 to rotate the rotation angle counterclockwise to calculate the second image capture Obtain the rotation angle of the module 121/123 and control the rotation angle of the second image capturing module 121/123 clockwise.

After the control module 150 controls the second image capturing module to rotate like the shooting target 210, the first image capturing module 110 can capture the first target image including the shooting target 210 to generate the first target image including the first target image. For the image stream, the second image capture module 120 can also capture the second target image synchronously with the first image capture module 110 and generate a second image stream including the second target image (step 550 ). In this embodiment, it is assumed that the control module 150 can generate a start signal, so that the first image capture module 110 and the second image capture module 120 can start capturing the target image synchronously when the control module 150 generates the start signal. to generate a synchronized first video stream and a second video stream.

After the image capturing modules synchronously capture the target image and generate a synchronous video stream, the imaging module 160 can generate a stream combination including the video streams synchronously generated by all the image capturing modules (step 560 ). In this embodiment, it is assumed that the imaging module 160 can determine the first image stream and the second image stream according to the arrangement position (relative position) of each image capture module in the device 100 or the module identification data of the image capture module. The arrangement order of the target images to be synchronized in the video stream, and the first video stream and the The synchronized target images in the second image stream are sequentially added to different pixel blocks of the same frame, so as to generate a stream combination including the image streams synchronously generated by all image capture modules.

In this way, through this creation, the target images of the user at different angles at the same time can be obtained through one device for subsequent use, for example, stored as a streaming file for playback, or sent to an external device for display.

For example, in the above-mentioned embodiment, if the device 100 includes the communication module 170, after the imaging module 160 generates the stream combination (step 560), the communication module 170 can combine the stream generated by the imaging module 160 The image is transmitted to the display device 250, so that the display device 250 displays one or more video streams included in the stream combination (step 570). For example, the display device 250 can sequentially extract target images of different pixel regions from each frame combined by streams at regular intervals and display the extracted target images to broadcast different image streams in rotation. The display device 250 can also directly display The combination of streams makes the displayed images simultaneously present users with different shooting angles. The display device 250 extracts the target images in each pixel area from each frame of the combination of streams and displays the read target images with corresponding pixels so as to Different viewing angles show video streams corresponding to shooting angles.

To sum up, it can be seen that the difference between this invention and the prior art lies in that after the distance parameter is judged from the detection image including the shooting target captured by the first image capture module, according to the distance parameter and each second image capture Calculate the rotation angle of each second image capture module by taking the device distance between the module and the first image capture module, and control the rotation of each second image capture module according to each rotation angle to generate The technical means of the combination of the first video stream and the second video streams generated synchronously by the image capture module and each second image capture module can solve the problems existing in the prior art by this technical means Setting up a streaming media environment that provides multiple shooting angles is likely to cause problems for photographers, thereby achieving the technical effect of reducing the complexity of setting up a video environment with multiple shooting angles.
