Description

[Technical Field]

[0001] This invention relates to a computer switching device, and more particularly to a computer switching device that supports image segmentation and its operating method. [Previous Technology]

[0002] With the advancement of electronic technology, many commercial activities or exhibitions have shifted from paper posters to screens. For some large-sized pictures, if only one screen is used to display them, the size of the picture must be reduced to make the picture appear on the screen completely, making it difficult to view. Therefore, in order to display pictures at their original size, multiple televisions are usually used to form a screen to display the pictures.

[0003] For some IT engineers, multiple screens may be needed to display code when editing programs. For esports players, multiple screens may be needed to display various game screens.

[0004] However, to achieve the visual effects of the above-mentioned screen wall, additional image processing equipment must be installed to display the image source on multiple screens. However, current image processing equipment requires a lot of time for beginners to learn how to set it up, and the price of image processing equipment is also quite high. [Summary of the Invention]

[0005] The technical problem to be solved by the present invention is to provide a computer switching device and its operation method in view of the prior art.

[0006] To solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide a computer switching device. The computer switching device is configured to connect to a computer, a display screen, a mouse, and a keyboard. The computer switching device includes a processing circuit, a storage circuit, multiple switching devices, and multiple computer connection ports. The processing circuit is connected to the storage circuit and the multiple switching devices. The multiple computer connection ports are respectively connected to the multiple switching devices, and one of the computer connection ports is configured to connect to the computer. Based on the operation of the switching devices, the processing circuit is electrically connected to the computer. The processing circuit accesses the storage circuit to perform the following operations: acquiring an original image from the computer; dividing the original image into multiple sub-images; identifying the picture portion and blank portion of each sub-image based on the pixel data of each sub-image; arranging the multiple picture portions to establish a corrected image; and controlling the display screen to display the corrected image.

[0007] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is to provide an operation method for a computer switching device. The operation method includes: electrically connecting the processing circuit to the computer by operating the switching device; acquiring the original image from the computer by the processing circuit; dividing the original image into multiple sub-images by the processing circuit; identifying the screen portion and blank portion of each sub-image based on the pixel data of each sub-image by the processing circuit; arranging the multiple screen portions to establish a corrected image by the processing circuit; and controlling the display screen to display the corrected image by the processing circuit.

[0008] One of the beneficial effects of the present invention is that the computer switching device and its operation method provided by the present invention can pre-divide the image into multiple sub-images, regardless of the image having any special aspect ratio, without the need to display the image through multiple display screens or configure additional image processing equipment for image processing, and display the multiple sub-images side by side on one display screen in various arrangement methods according to the customized ratio requirements.
