According to an embodiment, the trigger 150 can be a switch. When the switch is triggered to open, the trigger 150 issues a trigger command to the recognition processor 130 to activate the image extractor 110 and the illuminator 120. Otherwise, when the switch is off, the switch does not issue a trigger command to the recognition processor 130, and the sensor 140 is activated, so that the input device 100 with the barcode recognition function maintains the original operation mode, for example, the mouse mode. .

The trigger 150 is, for example, a gravity detector, an angular acceleration detector, an acceleration detector, or the like. The trigger 150 continuously outputs a detection value to the recognition processor 130. And when the detected value exceeds a threshold, the recognition processor 130 activates the image extractor 110 and the illuminator 120. For example, when the input device 100 having the barcode recognition function is picked up by a user from the desktop and exceeds a predetermined angle, the threshold value is reached, and the recognition processor 130 will display the image capture device 110 and the illumination. The device 120 starts up. In addition, when the detected value does not exceed the threshold value, the recognition processor 130 does not activate the image extractor 110 and the illuminator 120, but activates the sensor 140, so that the input device 100 having the barcode recognition function remains original.

Please refer to FIG. 2, which is a flowchart of an embodiment of the barcode identification method according to the present disclosure. The barcode identification method may include the following steps. Identification processor 130 It is judged whether or not the trigger 150 is triggered (step S220). When the trigger 150 is triggered, the image capturer 110 captures the barcode image of the cue pattern (step S240). The recognition processor 130 recognizes the barcode image and obtains identification information of the barcode image (step S250). When the trigger 150 is not triggered, the sensor 140 senses the displacement operation of the input device 100 having the barcode recognition function to generate the displacement operation information (step S260). And the transmitter 160 outputs the identification information or the displacement operation information (step S270).

In step S240, the image capturing device 110 extracts a barcode image from the image capturing range of the illuminator 120. Then, in step S250, the recognition processor 130 identifies and processes the barcode image captured by the image capture device 110 to obtain the identification information included in the barcode image. In step S260, the sensor 140 senses the displacement operation of the input device 100 having the barcode recognition function, and generates displacement operation information according to the sensing result of the sensor 140.

Finally, after the recognition processor 130 recognizes the barcode image in step S270 and obtains the identification information included in the barcode image, the identification processor 130 transmits the obtained identification information to a computer of a personal computer (PC) through the transmitter. On the screen of the screen or the laptop, the identification information obtained by the recognition processor 130 is displayed for viewing and understanding by the user. The object transmitted by the transmitter 160 can be any screen of a system with display identification information, and is not limited to a computer screen of a personal computer or a screen of a notebook computer.

In another embodiment, the image capture device 110 captures the barcode image and transmits it to the recognition processor 130. The recognition processor 130 does not process the barcode image, but directly delivers the barcode image to the transmitter 160 for transmission to the computer. After receiving the barcode image, the computer performs identification processing and obtains identification information of the barcode image. After the computer obtains the identification information of the barcode image, it will be directly displayed on the screen for the user to view and understand the content.

Please continue to refer to FIG. 3, which is a flowchart of another embodiment of the barcode identification method according to the present disclosure. In the embodiment of FIG. 3, steps S220, S240, S250, S260, and S270 can be referred to the embodiment of FIG. 2, and thus will not be described again.

Before step S240, the image capturing device 110 may first obtain a bar from the prompt pattern. The position of the code image (step S230). Before the image capturing device 110 extracts the barcode image from the image capturing range of the illuminator 120, the image capturing device 110 obtains the position of the barcode image from the image capturing range of the illuminator 120. The bar code image will be in the positioning frame or the positioning area of the illuminator 120, or the illuminator 120 will place the positioning point on the bar code image. The image capture device 110 first learns the location of the barcode image. By adding this step, the success rate of the bar code image in the cue pattern in step S240 can be increased and the time taken can be reduced.

Please refer to FIG. 4 again, which is a flowchart of another embodiment of the barcode identification method according to the present disclosure. In the embodiment of FIG. 4, steps S220, S230, S240, S250, S260, and S270 can refer to the embodiments of FIG. 2 and FIG. 3, and thus will not be described again.

After step S220, and before step S260, the following steps may also be included. The recognition processor 130 activates the sensor 140 (step S215) without activating the illuminator 120 and the image capturer 110. In addition, after step S220, and before step S230, the following steps may also be included. The recognition processor 130 activates the image capturer 110 and the illuminator 120 (step S225).

That is to say, before the position where the illuminator 120 starts to start and locate the barcode image and the image capturing device 110 starts to capture the barcode image according to the position of the barcode image, both of them are in an unactivated state. It is determined by the recognition processor 130 whether the trigger 150 is triggered to determine the operation mode of the input device 100 having the barcode recognition function.

If the flip-flop 150 is triggered, the flip-flop 150 with the switch will issue a trigger command to cause the recognition processor 130 to cause the image picker 110 and the illuminator 120 to be activated. The flip-flop 150 with the gravity detector, the angular acceleration detector, the acceleration detector, and the like continuously generates the detection value to the identification processor 130. When the input device 100 having the barcode recognition function is picked up by a user from the desktop and the angle with the desktop continues to increase, the detected value of the trigger 150 also reacts and changes the value. Moreover, when the detected value reaches a predetermined threshold, the recognition processor 130 knows that the trigger 150 has been triggered, and activates the image extractor 110 and the illuminator 120. On the other hand, when the detected value generated by the flip-flop 150 does not reach the preset threshold, the recognition processor 130 activates the sensor 140 without activating the image extractor 110 and the illuminator 120.

According to this embodiment, the preset states of the image extractor 110 and the illuminator 120 are all in an unactivated state. When the trigger 150 is judged to be triggered in step S220, the flip-flop 150 having the switch issues a trigger command to the recognition processor 130. After the recognition processor 130 receives the trigger command, the image extractor 110 and the illuminator 120 are activated and proceeds to step S230. The trigger 150 normally sends a detection value to the recognition processor 130 continuously.

When the input device 100 having the barcode recognition function is picked up by the user from the desktop and the angle with the desktop continues to increase, the detected value generated by the trigger 150 is also changed. Therefore, the recognition processor 130 receiving the detection value greater than the threshold value knows that the trigger 150 has been triggered, and the recognition processor 130 activates the image capturer 110 and the illuminator 120 (step S225) and enters Step S230. On the other hand, when the trigger 150 is not triggered, the recognition processor 130 activates the sensor 140 and proceeds to step S215, and keeps the image extractor 110 and the illuminator 120 in an unactivated state.
