The touch surveillance video recording device 100 includes: a first video input interface 110, a second video input interface 120, the touch screen 130, an image processing unit 140, and a control unit 150.
5 The image processing unit 140 is electrically connected between the first video input interface 110, the second video input interface 120, and the touch screen 130. The control unit 150 is electrically connected to the touch screen 130 and the image processing unit 140.
The first video input interface 110 is used to receive a first video signal 410 from the 10 camera 200, and output the first video signal 410 to the image processing unit 140. The second video input interface 120 is used to receive a second video signal 420 from the host 300, and output the second video signal 420 to the image processing unit 140. The touch screen 130 detects a touched position to obtain a first coordinate in a display range of the touch screen 130.
15 Please refer to FIG. 1 and FIG. 2, in which the image processing unit 140 outputs an integrated video signal 430 to the touch screen 130 according to the first video signal 410 and the second video signal 420, and in a display split mode displays a first image corresponding to the first video signal 410 in a first sub display area 501 of the touch screen 130 and displays a second image corresponding to the second video signal 420 in a second 20 sub display area 502 of the touch screen 130. When a first coordinate 510 is located in the second sub display area 502, the control unit 150 converts the first coordinate 510 into a second coordinate 520 relative to the whole touch screen 130 according to a relative position of the first coordinate 510 located in the second sub display area 502, and transmits the second coordinate 520 to the host 300. In other words, the control unit 150 may 25 translate the first coordinate 510 into the second coordinate 520 according to a proportional relationship between the second sub display area 502 and the whole screen.

As shown in FIG. 1, the touch screen 130 includes a touch panel 131 and a display screen 133. The touch panel 131 includes elements (no shown), such as a touch sensing module and a touch unit. The touch sensing module detects a touched position. The touch unit converts one or more touched positions into a coordinate. Therefore, the 5 control unit 150 may obtain the coordinate (the first coordinate 510), of the touched position on the touch screen 130. The structure and operating principles of the touch panel 131 are well known by persons skilled in the art, and are therefore not repeated herein. It should be noted that the display range of the touch screen 130 is equivalent to a display range of the display screen 133. The control unit 150 may be a Central Processing Unit 10 (CPU), a Micro Processor Unit (MPU), a Digital Signal Processor (DSP), a Micro Control Unit (MCU), and an image/sound codec chip, or a combination thereof.
FIG. 2 illustrates a 2-split display split mode, in which the display range of the touch screen 130 is split into two parts, for example, a left half and a right half. The left half includes the first sub display area 501. The right half includes the second sub display area 15 502. In order to maintain aspect ratios of the first image and the second image, the first sub display area 501 may occupy only a part of the left half of the touch screen 130. Similarly, the second sub display area 502 may occupy only a part of the right half of the touch screen 130. Alternatively, in order to maintain the aspect ratios of the first image and the second image, the first sub display area 501 may be processed by being rotated 20 counterclockwise by 90 degrees or clockwise by 90 degrees, so as to occupy the left half of the substantially whole touch screen 130. Similarly, the second sub display area 502 may be processed by being rotated counterclockwise by 90 degrees or clockwise by 90 degrees, so as to occupy the right half of the substantially whole touch screen 130. Alternatively, the aspect ratios of the first image and the second image may not be maintained, and the 25 first image is stretched and displayed in the left half of the whole touch screen 130. Similarly, the second image is stretched and displayed in the right half of the whole touch screen 130.
In some embodiments, the control unit 150 may provide a graphic user interface, so
5
that a split manner may be selected for the display split mode, so as to determine respective pixel areas of the first sub display area 501 and the second sub display area 502 on the touch screen 130. Further, the control unit 150 transmits the determined pixel areas to the image processing unit 140, so that the image processing unit 140 embeds the first image in 5 the first sub display area 501, and embeds the second image in the second sub display area 502. The operating principles of embedding and displaying the video images in specific pixel areas of the screen are well known by persons skilled in the art, and are therefore not repeated herein.

The display range of the touch screen 130 is split into a first sub display area 501, a second sub display area 502, a third sub display area 503, and a fourth sub display area 504. If in addition to being 15 connected to the camera 200 and the host 300, the touch surveillance video recording device 100 is further connected to another camera 200 and another host 300, or other electronic apparatuses having a video output function, the third sub display area 503 and the fourth sub display area 504 may be used to display output images thereof.
As shown in FIG. 4, a 6-split display split mode is illustrated. In addition to the first 20 to fourth sub display areas, the display range of the touch screen 130 is further split into a fifth sub display area 505 and a sixth sub display area 506 capable of displaying output images of other electronic apparatuses.
FIG. 2 to FIG. 4 are only exemplary, and the present invention is not limited thereto. The display range of the touch screen 130 may be split into parts, the number of which may 25 be adjusted according to needs or the number of external devices connected to the touch surveillance video recording device 100. Further, the position, proportion, and size of each sub display area may be adjusted according to needs, and the total range of all the sub
6
display areas may be smaller than or equal to the display range of the touch screen 130.
In some embodiments, the touch surveillance video recording device 100 may include a plurality of communication interfaces 170, so that when the touch surveillance video recording device 100 is connected to a plurality of hosts 300, all the hosts 300 may be 5 operated correspondingly through the sub display areas on the touch screen 130.
As shown in FIG. 1, in some embodiments, the touch surveillance video recording device 100 further includes a storage unit 160. The storage unit 160 is electrically connected to the control unit 150, and used to store the first video signal 410 as an image file, which is used as a video record. The storage unit 160 may be a hard disk, a flash 10 memory, or a memory card, but the present invention is not limited thereto.
As shown in FIG. 1, in some embodiments, the touch surveillance video recording device 100 further includes a communication interface 170. The communication interface 170 is electrically connected to the control unit 150, through which the control unit 150 transmits the second coordinate 520 to the host 300. The communication interface 170 15 may be a Universal Serial Bus (USB) interface.
In some embodiments, the touch panel 131 may be a resistive touch panel, a capacitive touch panel, an infrared ray touch panel, an ultrasonic touch panel, or a surface acoustic wave touch panel.
In some embodiments, the first video input interface 110 may be a Video Graphics 20 Array (VGA) interface, a composite video interface, a Digital Visual Interface (DVI) interface, a High-Definition Multimedia Interface (HDMI) interface, a DisplayPort interface, or a High Definition Serial Digital Input/Output (HD-SDI) interface.
In some embodiments, the second video input interface 120 may be a VGA interface, a composite video interface, a DVI interface, an HDMI interface, a DisplayPort interface, or 25 an HD-SDI interface.

FIG. 5 is a schematic block diagram of a touch surveillance video recording device 100 according to a second embodiment of the present invention.
As shown in FIG. 5 substantially the same as FIG. 1, the touch surveillance video recording device 100 further includes a changeover switch 180. The changeover switch 5 180 is electrically connected between the touch screen 130, the control unit 150, and the communication interface 170. In an exclusive display mode, the display screen 133 only displays a video signal transmitted by one of the camera 200 and the host 300. When a first image is displayed on the whole touch screen 130, the changeover switch 180 enables electrical connection between the control unit 150 and the touch screen 130, so that a first 10 coordinate 510 is transmitted to the control unit 150. When a second image is displayed on the whole touch screen 130, the changeover switch 180 enables electrical connection between the communication interface 170 and the touch screen 130, so that a first coordinate 510 is transmitted to the host 300. Therefore, the touch surveillance video recording device 100 may transmit a coordinate of a touched position to the corresponding 15 host or the control unit 150 thereof according to the image displayed by the touch screen 130.
FIG. 6 is a flow chart of a touch surveillance video recording device 100 transmitting a second coordinate 520 to a host 300 according to an embodiment of the present invention.
Please refer to FIG. 1 and FIG. 6, in which the control unit 150 of the touch 20 surveillance video recording device 100 initializes peripheral elements such as the touch panel 131 (Step S601). The control unit 150 displays a graphic user interface on the touch screen 130, so as to show display mode options to be selected by a user (Step S602). Then, the control unit 150 may reposition a touch coordinate according to the display mode (for example, a display split mode or an exclusive display mode), selected by the user, so as to 25 make a pixel area covered by a second image correspond to the touch coordinate on the touch panel 131 (Step S603). When a single-point or multi-point touch event occurs, a first coordinate 510 representing a touched position is translated into a second coordinate
8
520 by interpolation (Step S604). Finally, the second coordinate 520 is output to the host 300 (Step S605).
In view of the above, when the touch surveillance video recording device according to the present invention is applied to a computer and surveillance video recording system, the 5 touch screen can be used efficiently, and the space for placing the devices may be saved.
