[0051] Hereinafter, an image distribution multiplexing processing apparatus and method for an optical sensor image according to the present invention will be described in detail with reference to the attached drawings.

[0052] First, the present invention converts analog images provided from an optical sensor (e.g., an electro-optical system (e.g., TV, IR), a periscope (e.g., LLLTV)) into digital images, then multiplexes the image distribution method within the combat system, and enables the storage of compressed images when storing images.

[0053] FIG. 2 is a diagram showing the block configuration of an image distribution multiplexing processing device for an optical sensor image according to the present invention.

[0054] Referring to FIG. 2, the image distribution multiplexing processing device for an optical sensor image according to the present invention may include an electro-optical system (100), a periscope (200), and a combat system (300).

[0055] The above combat system (300) may include a video distribution device (310), a video distribution recording device 1 (320), a video distribution recording device 2 (330), and a multi-functional console (340).

[0056] The video distribution device (310) may include a converter (311) and a video switch (312), and the multifunction console (340) may include a display processing device (341).

[0057] The above image distribution recording device 1 (320) may include a processing device (321) and a storage device (322), and the above image distribution recording device 2 (330) may include a processing device (331) and a storage device (332).

[0058] Each of the above-mentioned multiple optical sensors, i.e., the electro-optical system (100) shown in FIG. 2, for example, TV, IR, and the periscope (200), for example, LLLTV, generates an analog image and transmits each generated analog image to the video distribution device (300) of the combat system (300).

[0059] The video distribution device (310) converts each analog signal transmitted from the electro-optical system (100) and the periscope (200) into a digital signal, and distributes and transmits each converted digital video signal to the video distribution recording devices 1 and 2 (320, 330) and the multi-function console (340), respectively.

[0060] That is, the converter (311) of the video distribution device (310) converts each analog signal transmitted from the electro-optical system (100) and the periscope (200) into a digital signal, and then provides each converted digital signal to the video switch (312).

[0061] The above video switch (312) provides each digital signal converted through the converter (311) to the display processing unit (341) of the multi-functional console (340) via a single digital video line, and at the same time transmits each converted digital signal to the redundant video distribution recording devices 1 and 2 (320, 330) respectively via their respective digital video lines. Here, the reason for duplicating the video distribution recording devices is to enable compressed video processing by switching in the event of a malfunction in one video distribution recording device or a physical problem with the video line.

[0062] Each processing device (321, 331) of the above-mentioned video distribution recording devices 1 and 2 (320, 330) compresses each received digital video signal and then stores each compressed video in each storage device (322, 332).

[0063] Meanwhile, each processing unit (321, 331) of the above-mentioned video distribution recording devices 1 and 2 (320, 33) provides each compressed video signal to the display processing unit (341) of the multi-functional console (340) through the combat system network.

[0064] When the display processing device (341) of the multi-functional console (340) receives an uncompressed digital image transmitted through a digital image line from the video distribution device (310), it displays the received uncompressed digital image on the display device, and also when it receives a compressed image transmitted through a combat system network from the video distribution recording devices 1 and 2 (320, 330), it displays the received compressed image on the display device.

[0065] Here, the display processing device (341) of the multi-functional console (340) processes the uncompressed digital video received from the video distribution device (310) as a first priority, and if the uncompressed digital video transmitted from the video distribution device (310) has a problem such as a physical problem of the digital video line or a signal delay, the compressed video transmitted from the video distribution recording device 1, 2 (320, 330) among the compressed videos transmitted from the video distribution recording device initially set by the operator is decompressed, and then the decompressed video is displayed on the display device.

[0066] That is, the display processing unit (341) of the multi-functional console (340) displays the uncompressed video transmitted from the video distribution unit (310) as the first priority to minimize delay time among the videos transmitted from the video distribution unit (310) and the redundant video distribution recording units 1 and 2 (320, 330), and if a problem occurs with receiving the uncompressed video, displays the compressed video received from the video distribution recording unit selected by the operator among the video distribution recording units 1 and 2 (320, 330) as the second priority to the display unit.

[0068] The operation of the image distribution multiplexing processing device for an optical sensor image according to the present invention configured as described above, and the corresponding image distribution multiplexing processing method for an optical sensor image according to the present invention, will be explained step-by-step with reference to the attached Fig. 3.

[0069] FIG. 3 is a diagram showing an operation flowchart for an image distribution multiplexing processing method for an optical sensor image according to the present invention.

[0070] Referring to FIG. 3, each of the plurality of optical sensors, namely the electro-optical system (e.g., TV, IR) and the periscope (e.g., LLLTV), generates an analog image and transmits each generated analog image to the video distribution device (300) of the combat system (300).

[0071] The video distribution device (310) receives each analog signal transmitted from the electro-optical system (100) and the periscope (200) (S310).

[0072] Next, the received analog video signal is converted into a digital signal (S320).

[0073] Next, each of the converted uncompressed digital video signals is transmitted to a multi-functional console and a redundant video distribution recording device (S330).

[0074] That is, the video distribution device converts each analog signal transmitted from the electro-optical system and the periscope into a digital signal, and then provides each converted digital signal to a multi-function console via a single digital video line, while simultaneously transmitting each converted digital signal to a redundant video distribution recording device via a respective digital video line. Here, the reason for duplicating the video distribution recording device is to enable compressed video processing by switching in the event of a malfunction in one of the video distribution recording devices or a physical problem with the video line.

[0075] Next, each of the redundant video distribution recording devices compresses each received digital video signal, stores each compressed video in each storage device, and simultaneously transmits each compressed video signal to each multi-functional console through the combat system network (S340).

[0076] Next, the multifunction console receives an uncompressed digital video transmitted from the video distribution device through a digital video line and displays the received uncompressed digital video on a display device (S350).

[0077] Next, while displaying the uncompressed digital image on the display device, it is determined whether a problem has occurred with the uncompressed digital image (S360). That is, it is determined whether problems such as image delay or image interruption occur due to a physical problem with the digital image line.

[0078] If, as a result of the judgment, no problem occurs with the uncompressed digital video signal, the above step S350 is continuously performed, and if a problem occurs with the uncompressed digital video signal, the compressed video transmitted from the video distribution recording device set by the initial operator among the redundant video distribution recording devices is decompressed, and the decompressed video is displayed on the display device (S370).

[0079] To explain the above S370 step in more detail, the multifunction console processes the display of uncompressed digital video received from the video distribution device with first priority. If a problem such as a physical issue with the digital video line or a signal delay occurs with the uncompressed digital video transmitted from the video distribution device, the console decompresses the compressed video transmitted from the video distribution recording device initially set by the operator among the compressed videos transmitted from the redundant video distribution recording devices, and then displays the decompressed video on the display device.

[0080] That is, the multi-functional console displays the uncompressed video transmitted from the video distribution device as the first priority on the display device to minimize latency among the videos transmitted from the video distribution device and the redundant video distribution recording device, and if a problem occurs with the reception of the uncompressed video, displays the compressed video received from the video distribution recording device selected by the operator among the redundant video distribution recording devices as the second priority on the display device.

[0082] The image distribution multiplexing processing method for an optical sensor image according to one embodiment of the present invention described above may be implemented as a program (or application) and stored on a medium to be executed in combination with a computer, which is hardware.

[0083] The aforementioned program may include code encoded in computer languages ​​such as C, C++, JAVA, Ruby, and machine language, which can be read by the computer's processor (CPU) through the computer's device interface, in order for the computer to read the program and execute the methods implemented in the program.

In addition, if the processor of the computer needs to communicate with any other computer or server located remotely in order to execute the above functions, the code may further include communication-related code regarding how to communicate with any other computer or server located remotely using the communication module of the computer, and what information or media to transmit or receive during communication.

[0084] The above-mentioned storage medium refers to a medium that stores data semi-permanently and is readable by a device, rather than a medium that stores data for a short period of time, such as a register, cache, or memory. Specifically, examples of the above-mentioned storage medium include, but are not limited to, ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage device.
