In addition, the material of one of the bonding pad 120 and the carrier disk 940 is a ferromagnetic substance (for example, a magnet), and the other material of the bonding pad 120 and the carrier disk 940 is a ferromagnetic substance (for example, a magnet). Or a paramagnetic substance (for example iron). In this way, when the user approaches the camera 100 to the stand 900, the camera 100 can be magnetically attracted to the stand 900; and when the user wants to remove the camera 100, the camera can be separated by gently applying force. 100 with bracket 900.

The user can set up multiple racks 900 at home or in the workplace and move the camera 100 to a different rack 900 depending on the needs of the use. When the rotation angles of the first axial direction L1 and the second axial direction L2 of the bracket 900 are fixed, after the user sets the camera 100 on the bracket 900, only the camera 100 needs to adjust the third axial direction L3 as the axis. The angle of rotation enables the camera 100 to capture a Region of Interest (ROI).

Please refer to FIG. 5, which shows a block diagram of the camera 100. apart from In addition to the body 110 and the splice tray 120, the camera 100 further includes an accelerometer 130, a storage unit 140, a processing unit 150, a prompting unit 160, and a communication unit 170.

Please refer to FIG. 6, which is a flow chart showing a method for setting the camera 100 according to an embodiment of the present invention. When the user uses the camera 100, the user can transmit the image or the image to the user device 700 of the user through the communication unit 170. The user can see the image or picture currently captured by the camera 100 on the user interface of the user device 700. When the camera 100 is installed for the first time, the user can view the captured image or screen to confirm whether the camera 100 is rotated to the correct position, and confirm the set parameters (such as brightness value, chroma value, focal length value, and focus). Location) is correct. Through the setting method of FIG. 6, the rotational position and parameters of the camera 100 can be recorded to facilitate the installation of the camera 100 again. Actions.

First, in step S110, the processing unit 150 obtains an identification code ID1 of one of the racks 900. In this step, the identification code ID1 can be obtained through the user interface of the user device 700. That is, the user can operate the user interface to inform the processing unit 150 which bracket 900 is to be set now. Alternatively, in another embodiment, a radio frequency identification tag (Radio Frequency Identification tag) may be separately disposed on each of the brackets 900. When the camera 100 is attached to the bracket 900, the radio frequency identification tag of the bracket 900 may be sensed. Knowledge ID ID1.

In step S111, the user adjusts the angle, orientation or position of the camera 100. As an example of FIGS. 3 to 4, for example, the camera 100 is rotated with the third axial direction L3 as an axis to enable the camera 100 to capture a region of interest (ROI). After the camera 100 is mounted to the user, the user interface can be operated to send a trigger signal S1 to the communication unit 170, and then the communication unit 170 transmits the trigger signal S1 to the processing unit 150. In another embodiment, the camera 100 can also be provided with a trigger button, and the user can press the trigger button to send the trigger signal S1 to the processing unit 150.

Next, in step S120, the processing unit 150 determines whether the trigger signal S1 is received. If the trigger signal S1 is received, it indicates that the user has completed installation, so the process directly proceeds to step S130. If the trigger signal S1 is not received, it indicates that the user has not completed installation, so step S111 is repeatedly executed to wait for the user to complete the installation.

Next, in step S130, the acceleration gauge 130 is used to obtain a gravity. The first component of the acceleration is one of the three coordinate axes (for example, the X axis, the Y axis, and the Z axis that are perpendicular to each other).

Then, in step S140, the first component combination G1 is stored in the storage unit 140 for use when the camera 100 is mounted again.

Next, in step S150, a correspondence relationship R1 of the first component combination G1 and the identification code ID1 is stored. The correspondence R1 is, for example, a look-up table for use when the camera 100 is mounted again.

Through the above setting method, the first component combination G1 and its corresponding relationship R1 with the identification code ID1 are stored in the storage unit 140, so that when the user installs the camera 100 again, the user can automatically determine the camera without continuously checking the screen. Is the rotation position of 100 correct?

The adjustment method when the user moves the camera 100 to a certain bracket 900 will be further described below. Please refer to FIG. 7, which illustrates a flow chart of a method for adjusting the camera 100 according to an embodiment of the present invention. First, in step S210, the processing unit 150 obtains the identification code ID1 of the cradle 900. In this step, the identification code ID1 can be obtained through the user interface of the user device 700. That is, the user can operate the user interface to inform the processing unit 150 which rack 900 to install now. Alternatively, in another embodiment, a radio frequency identification tag may be separately disposed on each of the brackets 900. When the camera 100 is attached to the bracket 900, the radio frequency identification tag of the bracket 900 may be sensed to obtain the identification code ID1.

In step S220, the processing unit 150 obtains the first component combination G1 pre-stored in the gravity acceleration of the camera 100 on the above three coordinate axes. At this step In the step, the processing unit 150 searches for the first component combination G1 in the storage unit 140 according to the corresponding relationship R1.

Next, in step S221, the user adjusts the angle, orientation or position of the camera 100. As an example of FIGS. 3 to 4, for example, the camera 100 is rotated about the third axial direction L3.

In step S230, the acceleration gauge 130 is used for instantaneous measurement to instantly obtain the gravity acceleration of the camera 100 on one of the three coordinate axes, the second component combination G2. As the camera 100 rotates, the second component combination G2 will constantly change.

Then, in step S250, the processing unit 150 determines whether the second component combination G2 is substantially identical to the first component combination G1. The term "substantially" as used in the disclosure refers to various reasonable errors resulting from component measurement and calculation. When the second component combination G2 is substantially the same as the first component combination G1, the process proceeds to step S260; if the second component combination G2 is substantially different from the first component combination G1, the process proceeds to step S280.

In step S260, the processing unit 150 determines that the position at which the camera 100 is mounted on the stand 900 has been adjusted.

Next, in step S270, the processing unit 150 controls the prompting unit 160 to issue a prompt message M1 according to the result that it is determined that the second component combination G2 is substantially the same as the first component combination G1. As shown in FIG. 1, the prompting unit 160 may be a ring type lamp. The prompting unit 160 can emit a green light prompt message M1 indicating that the position of the camera 100 mounted on the bracket 900 has been adjusted.

In step S280, the processing unit 150 determines that the position at which the camera 100 is mounted on the stand 900 has not been adjusted.

Next, in step S290, the processing unit 150 controls the prompting unit 160 to issue another prompt message M2 according to the result that it is determined that the second component combination G2 is substantially different from the first component combination G1. As shown in FIG. 1, the prompting unit 160 may be a ring type lamp. The prompting unit 160 can emit a red light prompt message M2 indicating that the position of the camera 100 mounted on the bracket 900 has not been adjusted.

That is to say, the user only needs to rotate the camera 100 to see if the color of the prompting unit 160 is changed from red light to green light, and it can be known whether the position of the camera 100 mounted on the bracket 900 has been adjusted. This embodiment is described by taking an example in which the illuminating color of the prompting unit 160 is switched between green light and red light, but the illuminating color of the prompting unit 160 is not limited thereto. In other words, the illuminating color of the prompting unit 160 will be based on design considerations or requirements, and other colors that are useful for the user to clearly recognize.

In an embodiment, the prompt message M2 sent by the prompting unit 160 may include a direction of rotation information. The direction of rotation information is, for example, to inform the user to turn clockwise or counterclockwise. The direction of rotation information is related to the difference between the second component combination G2 and the first component combination G1. For example, the clockwise horoscope can be used to inform the user to rotate clockwise, and the counterclockwise horoscope can be used to inform the user to rotate counterclockwise.

In an embodiment, the prompt message M2 sent by the prompting unit 160 may include a rotation angle information. The rotation angle information is related to the second component group The difference between G2 and the first component combination G1. For example, the faster the flashing speed of the marquee, the greater the angle at which the rotation needs to be continued.

Through the above setting method and adjustment method, when the user moves the camera 100 to a certain bracket 900, the user can be automatically reminded whether the position of the camera 100 on the bracket 900 has been adjusted without continuously checking the screen.

Please refer to FIG. 8 to FIG. 8 . FIG. 8 is a block diagram of a camera 200 according to another embodiment. FIG. 9 is a flow chart of a method for adjusting the camera 200 according to another embodiment. In another embodiment, the camera 200 further includes a driver 280 and a motor 290. The camera 200 can be rotated by the motor 290 without the need for the user to manually. After the second component combination G2 is obtained in step S230, step S240 is further performed. In step S240, the processing unit 150 controls the driver 280 to drive the motor 290 to rotate the camera 290 to the camera 200.

In this step, the driving direction of one of the motors 290 may be related to the difference between the second component combination G2 and the first component combination G1. For example, the processing unit 150 can directly analyze whether the driving direction should be clockwise or counterclockwise according to the difference between the second component combination G2 and the first component combination G1.

In addition, in this step, one of the driving times of the motor 290 is more related to the difference between the second component combination G2 and the first component combination G1. For example, the processing unit 150 can directly analyze the length of the driving time according to the difference between the second component combination G2 and the first component combination G1 to directly rotate the camera 290 to the correct rotational position.

Automatically remind users through the above setting methods and adjustment methods Whether the position of the camera 100 on the stand 900 has been adjusted. In another embodiment, the following setting methods and adjustment methods can also be used to automatically remind the user whether the parameter settings of the camera 100 have been adjusted. Please refer to FIG. 10, which is a flow chart showing a method of setting the camera 100 according to another embodiment of the present invention. The setting method of the camera 100 of Fig. 10 is different from the setting method of the camera 100 of Fig. 6 in steps S111', S130', S140', and S150'.

In step S111', the user further adjusts one of the first brightness value, a first color value, a first focus value, and a first focus position of the camera 100. When the user adjusts the position of the camera 100 and the above various parameters, the trigger signal S1 can be issued.
