Description

Technical Field

[0001] This utility model relates to an image processing device, specifically to an image transmission system with adjustable arrangement mode and resolution. Background Technology

[0002] Existing image transmission systems include a transmitter, a network cable, and a receiver. The transmitter is located at a local location and is used to connect to the image source, while the receiver is located at a remote location and is used to connect to the display device. The appropriate length of the network cable is selected based on the distance between the local and remote locations.

[0003] Since existing image transmission systems can only transmit one image at a time, when a user needs to transmit two images simultaneously, two separate image transmission systems must be used to transmit the two images.

[0004] If two images need to be displayed at the same resolution on two different display devices, an additional image resolution adjustment device is required. This device first adjusts the resolution of the two images to be identical, and then transmits each image to one of the two display devices. However, for beginners, it takes a considerable amount of time to learn how to set up the image resolution adjustment device, and such devices are also quite expensive. Utility Model Content

[0021] The following will illustrate this with specific examples.

[0022] Figure 1 This is a schematic diagram of the first embodiment of the image transmission system of this utility model. Figure 2 for Figure 1 Functional block diagram of the image transmission system. See also Figure 1 and Figure 2 The image transmission system includes a transmitter 1, a transmission line 2, and a receiver 3. The transmission line 2 is a twisted pair or fiber optic cable, and its two ends are connected to the transmitter 1 and the receiver 3, respectively.

[0023] Transmitter 1 includes a processing circuit 11, a storage circuit 12, an array mode selection device 13, a keyboard port 14, a mouse port 15, a display device port 16, a display device port 17, a network port 18, a first audio / video input interface P1, a second audio / video input interface P2, a first universal serial bus interface P3, and a first audio input interface P4. The processing circuit 11 is connected to the storage circuit 12, the array mode selection device 13, the keyboard port 14, the mouse port 15, the display device port 16, the display device port 17, the network port 18, the first audio / video input interface P1, the second audio / video input interface P2, the first universal serial bus interface P3, and the first audio input interface P4. The processing circuit 11 is, for example, a programmable logic controller circuit, a microprocessor circuit, a microcontroller circuit, or other processor or controller with signal processing capabilities, while the storage circuit 12 is, for example, random access memory (RAM), read-only memory (ROM), flash memory, hard disk, or other storage devices with data storage capabilities. The first audio / video input interface P1 and the second audio / video input interface P2 are, for example, two HDMI ports, or one HDMI port and the other a DisplayPort port.

[0024] The arrangement mode selection device 13 includes a first knob 131 and multiple arrangement mode scales L1 to L5, each corresponding to a different image arrangement mode. The user can rotate the first knob 131 to align it with one of the multiple arrangement mode scales L1 to L5 to select one of the multiple image arrangement modes.

[0025] Keyboard port 14, mouse port 15, display device port 16, display device port 17, and network port 18 are respectively configured to connect keyboard K, mouse M, first display device V1, second display device V2, and transmission line 2. The first electronic device C1 is, for example, a first computer. The first computer has a dual display adapter, a universal serial bus interface, and a sound output interface. The two audio-visual output interfaces of the dual display adapter are respectively connected to the first audio-visual input interface P1 and the second audio-visual input interface P2 of the transmitter 1. The universal serial bus interface and the sound output interface of the first computer are respectively connected to the first universal serial bus interface P3 and the first sound input interface P4.

[0026] The user operates the keyboard K and mouse M, causing the first electronic device C1 to simultaneously transmit the first original image screen M1 and the second original image screen M2 to the transmitter 1, and also transmits the control signal K1 (e.g., USB signal) and the sound signal K2 to the transmitter 1. The first display device V1 and the second display device V2 simultaneously and respectively display the first original image screen M1 and the second original image screen M2.

[0027] The processing circuit 11 of the transmitter 1 accesses the storage circuit 12 to perform the following multiple operations. In connection with the first operation, the processing circuit 11 simultaneously acquires a first original image frame M1 and a second original image frame M2 from the first electronic device C1, and acquires the control signal K1 and the sound signal K2 of the first electronic device C1.

[0028] In the second operation, the processing circuit 11 arranges the first original image frame M1 and the second original image frame M2 according to the selected image arrangement mode to generate the corrected image frame U. For example, when the selected image arrangement mode is side-by-side along the horizontal direction (e.g., the X-axis direction), the corrected image U consists of the first original image frame M1 and the second original image frame M2 arranged side-by-side horizontally. Therefore, the user must pre-arrange the third display device V3 and the fourth display device V4 side-by-side along the horizontal direction.

[0029] Similarly, when the selected image arrangement mode is side-by-side along the vertical direction (e.g., the Y-axis), the corrected image screen consists of a first original image screen M1 and a second original image screen M2 arranged vertically side-by-side. Therefore, the user must pre-arrange the third display device V3 and the fourth display device V4 vertically side-by-side.

[0030] Receiver 3 includes processing circuitry 31, storage circuitry 32, resolution selection device 33, network port 34, two display device ports 35 and 36, universal serial bus interface 37, and audio output interface 38. Processing circuitry 31 is connected to storage circuitry 32, resolution selection device 33, network port 34, two display device ports 35 and 36, universal serial bus interface 37, and audio output interface 38. Processing circuitry 31 may be, for example, a programmable logic controller circuit, a microprocessor circuit, a microcontroller circuit, or other processor or controller with signal processing capabilities. Storage circuitry 32 may be, for example, random access memory (RAM), read-only memory (ROM), flash memory, hard disk, or other storage devices with data storage capabilities. Universal serial bus interface 37 can be configured to connect a USB flash drive, and audio output interface 38 can be configured to connect a speaker.

[0031] The resolution selection device 33 includes a second knob 331 and multiple resolution scales R1 to R5, each corresponding to a different image resolution. The user can rotate the second knob 331 to align it with one of the multiple resolution scales R1 to R5 to select one of the multiple image resolutions.

[0032] Network port 34 and two display device ports 35 and 36 are respectively configured to connect transmission line 2, third display device V3 and fourth display device V4.

[0033] The processing circuit 31 of the receiver 3 accesses the storage circuit 32 to perform the following multiple operations. In connection with the first operation, the processing circuit 31 acquires the corrected image frame U, the control signal K1, and the sound signal K2 from the transmitter 1, wherein the corrected image frame U is composed of a first original image frame M1 and a second original image frame M2.

[0034] In the second operation, processing circuit 31 controls third display device V3 and fourth display device V4 to display first original image frame M1 and second original image frame M2 respectively, according to the selected image arrangement mode and image resolution. For example, when the selected image arrangement mode is horizontal side-by-side and the selected image resolution is 4k, the horizontally side-by-side third display device V3 and fourth display device V4 display the first original image frame M1 and the second original image frame M2 respectively, and both have a resolution of 4k. When the selected image arrangement mode is vertical side-by-side and the selected image resolution is 1080p, the vertically side-by-side third display device V3 and fourth display device V4 display the first original image frame M1 and the second original image frame M2 respectively, and both have a resolution of 1080p.

The switching switch SW is, for example, a single-pole multi-throw mechanical switch. The user can operate the switching switch SW to electrically connect the processing circuit 11 to the first audio / video input interface P1, the second audio / video input interface P2, the first universal serial bus interface P3, and the first audio input interface P4, or to the third audio / video input interface P5, the fourth audio / video input interface P6, the second universal serial bus interface P7, and the second audio input interface P8.

The second computer's universal serial bus interface and audio output interface are connected to a second universal serial bus interface P7 and a second audio input interface P8, respectively.

[0037] When the first original image frame M1 and the second original image frame M2 are stored in the first electronic device C1, the user operates the switch SW to electrically connect the processing circuit 11 with the first audio-visual input interface P1, the second audio-visual input interface P2, the first universal serial bus interface P3, and the first audio input interface P4. Then, the user operates the keyboard K and the mouse M to cause the processing circuit 11 to simultaneously receive the first original image frame M1 and the second original image frame M2 from the first electronic device C1, and to control the first display device V1 and the second display device V2 to display the first original image frame M1 and the second original image frame M2 respectively.

[0039] When the processing circuit 11 simultaneously acquires the first original image frame M1 and the second original image frame M2 from the first electronic device C1, the processing circuit 11 arranges the first original image frame M1 and the second original image frame M2 according to the selected image arrangement mode to generate the corrected image frame U. Then, the transmitter 1 transmits the corrected image frame U to the receiver 3 via the transmission line 2. The processing circuit 31 of the receiver 3 receives the corrected image frame U from the transmitter 1 and controls the third display device V3 and the fourth display device V4 to display the first original image frame M1 and the second original image frame M2 respectively according to the selected image arrangement mode and image resolution.
