## Abstract

A video camera, a setting method and an adjusting method thereof are provided. The adjusting method of the video camera is for adjusting an installation position of the video camera on a stand. The adjusting method comprises following steps: A first vector set of a gravity acceleration on three coordinate axes pre-stored in the video camera is obtained. An angle, a direction or a position of the video camera is adjusted. A second vector set of the gravity acceleration of the video camera on the coordinate axes is obtained by an accelerometer. Whether the second vector set is substantially the same as the first vector set is determined. When the second vector set is substantially the same as the first vector set, it is concluded that an installation position of the video camera on the stand is completely adjusted.

## Claims

### Claim 1

An adjusting method of a video camera for adjusting an installation position of the video camera on a stand, wherein the adjusting method comprises:
obtaining an identification code of the stand;
obtaining a first vector set of a gravity acceleration on three coordinate axes pre-stored in the video camera, wherein in the step of obtaining the first vector set, the first vector set is obtained according to a correspondence relationship between the first vector set of the gravity acceleration and the identification code;
adjusting an angle, a direction or a position of the video camera;
obtaining a second vector set of the gravity acceleration of the video camera on the coordinate axes by an accelerometer in response to an adjustment of the angle, the direction or the position of the video camera;
determining whether the second vector set is the same as the first vector set; and
concluding that the installation position of the video camera on the stand is adjusted completely when the second vector set is the same as the first vector set.

### Claim 2 (depends on 1)

The adjusting method of the video camera according to claim 1, further comprising:
obtaining a setting value of a parameter pre-stored in the video camera;
adjusting a value of the parameter of the video camera;
obtaining an adjusted value of the parameter of the video camera in response to an adjustment of the value of the parameter of the video camera;
determining whether the setting value is the same as the adjusted value; and
concluding that the value of the parameter of the video camera is adjusted completely when the setting value is the same as the adjusted value.

### Claim 3 (depends on 1)

The adjusting method of the video camera according to claim 1, further comprising:
sending a prompting message according to a result of whether the second vector set is the same as the second vector set.

### Claim 4 (depends on 3)

The adjusting method of the video camera according to claim 3, wherein when the second vector set is different from the first vector set, the prompting message contains a message of rotation direction or a message of rotation angle, which are related to a difference between the second vector set and the first vector set.

### Claim 5

A video camera rotatably disposed on a stand, wherein the video camera comprises:
a body;
a communication unit for obtaining an identification code of the stand;
a storage unit for storing a first vector set of a gravity acceleration of the video camera on three coordinate axes;
an accelerometer for sensing a second vector set of the gravity acceleration of the video camera on the coordinate axes; and
a processing unit for obtaining the first vector set from the storage unit according to a correspondence relationship between the first vector set of the gravity acceleration and the identification code and determining whether the second vector set is the same as the first vector set, wherein when the second vector set is the same as the first vector set, the processing unit concludes that an installation position of the video camera on the stand is completely adjusted.

### Claim 6 (depends on 5)

The video camera according to claim 5, further comprising:
a connecting plate having a recess, wherein the stand has a bearing plate having a protrusion engaged in the recess, such that the connecting plate is rotatably disposed on the bearing plate.

### Claim 7 (depends on 6)

The video camera according to claim 6, wherein one of the connecting plate and the bearing plate is formed of a ferromagnetic material, and the other one of the connecting plate and the bearing plate is formed of a ferromagnetic material or a paramagnetic material.

### Claim 8 (depends on 5)

The video camera according to claim 5, further comprising:
a prompting unit for sending a prompting message according to a result of whether the second vector set is the same as the first vector set.

### Claim 9 (depends on 8)

The video camera according to claim 8, wherein the prompting unit is a ring light.

### Claim 10 (depends on 8)

The video camera according to claim 8, wherein when the second vector set is different from the first vector set, the prompting message contains a message of rotation direction or a message of rotation angle, which are related to a difference between the second vector set and the first vector set.

### Claim 11 (depends on 5)

The video camera according to claim 5, further comprising:
a motor for rotating the video camera; and
a driver for driving the motor, wherein a driving direction and a driving time of the motor are related to a difference between the second vector set and the first vector set.
