An image capturing device includes a photographing unit and a data processing unit, wherein the photographing unit is configured to acquire an image and transmit the image to the data processing unit, the image capturing device further comprising an adjusting device, a microprocessor, and a memory a unit and a gravity sensor for sensing a relative position between the camera and the gravity field and outputting an adjustment signal, wherein the memory unit is configured to store a standard angle value, and the microprocessor transmits the comparison The adjustment signal and the standard angle value output an adjustment value, and the microprocessor outputs the adjustment value to the adjustment device, and the adjustment device adjusts the photographing angle of the photographing unit according to the adjustment value. An image capturing device includes a photographing unit and a data processing unit, wherein the photographing unit is configured to acquire an image and transmit the image to the data processing unit, the camera device further comprising a microprocessor, a memory unit and a gravity a sensor for sensing a relative position between the camera and the gravity field and outputting an adjustment signal, the memory unit is configured to store a standard angle value, and the microprocessor transmits the adjustment signal to 098110127 Form number Α0101 Page 5 of 17 0982016672-0 201036430 Standard angle value to output an adjustment value, the microprocessor outputs the adjustment value to the data processing unit and the data processing unit adjusts the adjustment value according to the adjustment value image. [0008] Through the camera device, when the image is rotated by the deflection of the camera device, the microprocessor obtains the adjustment value by using the adjustment signal and the standard value, and automatically adjusts the imaging angle by the data processing unit or the photographing unit, which is convenient Operation, and high precision. Embodiments of the present invention include a camera unit 10, a data processing unit 11, a selection unit 12, a microprocessor 13, a memory unit 14, and a camera unit. A gravity sensor 15, a transfer unit 16, and an adjustment device 17. The photographing unit 10 includes a plurality of imaging lenses (not shown) and a charge coupled device (CCD) (not shown). The adjustment device 17 can be a motor and a motor driver. The motor driver drives the motor to adjust the imaging lens and the CCD to achieve adjustment of the photographing angle of the photographing unit 10. [0010] The photographing unit 10 is configured to acquire an image and transmit the image to the data processing unit 11. The gravity sensor 15 is configured to sense a relative position between the camera and the gravity field and output an adjustment signal. The adjustment signal is the deflection angle α of the photographing unit 10 with respect to the gravitational field. The adjustment signal may have a value range of 0 degrees <α < 360 degrees or -180 degrees < α < 180 degrees. When the value range of the adjustment signal is a positive real number set, the deflection angle 0 of the camera relative to the right of the gravity field ranges from 0 degrees to 0 degrees < 0 < 180 degrees, and the camera device is oriented relative to the gravitational field. The left deflection angle 0 ranges from 180 degrees <0<6〇; when the adjustment signal has a value range of 098110127, form number Α0101, page 6 of 17 pages 0982016672-0, the whole set, the camera The deflection angle of the device to the right relative to the gravity field is in the range of 0 degrees < 0 < 18 degrees, and the deflection angle of the camera relative to the gravity field to the left ranges from -180 degrees <; 0 < 0 degrees 〇 亥 3 3 recall unit 14 is used to store a standard value. When the value of the adjustment signal is a positive real number set, the standard value is 180 degrees; when the range of the adjustment signal is a whole real number set, the standard value is a degree, that is, the camera device and the gravity field are Vertical, at this time, the camera does not have any deflection. The microprocessor 13 outputs an adjustment value by comparing the adjustment signal and the standard value. The adjustment value is obtained by subtracting the adjustment signal from the standard value. In other embodiments, the comparison method can be changed according to actual needs. The sign of the adjustment value represents the deflection direction of the camera relative to the gravitational field. If the range of the adjustment signal is a positive real number set, the standard value is 180 degrees when the camera is relative to the gravitational field. When deflecting to the right, the deflection angle 0 is less than 180 degrees, and the adjustment value is a negative angle value; when the camera is deflected to the left with respect to the gravity field, the deflection angle 0 is greater than 180 degrees, and the adjustment value is Is a positive angle value. Therefore, the image before the rotation can be restored by the adjustment value. The microprocessor 13 also determines whether the imaging angle of the camera device needs to be adjusted by the magnitude of the adjustment value. For example, when the standard value is 18 degrees and the adjustment value is obtained by subtracting the standard value from the adjustment signal, only when the camera is deflected to the right with respect to the gravity field (9 is 0 degrees or 360 degrees, ie When the adjustment value is -180 degrees or 180 degrees, the imaging angle of the camera device does not need to be adjusted. The selection unit 12 is configured to select an imaging angle adjustment mode. In the embodiment, the selection unit 12 is a switching device, and the micro processing The unit 13 selectively communicates with the adjusting device 17 or the data processing unit 11 through the form numbering surface i page 7 / page 17364364. When the operator selects the microprocessor 13 to connect the data processing unit 11 At the time (hereinafter referred to as the first imaging angle adjustment mode), the microprocessor 13 inputs the adjustment value to the data processing unit 11, and the data processing unit 11 adjusts the image according to the adjustment value to obtain a correct image frame. When the operator selects the microprocessor 13 to connect to the adjusting device 17 (hereinafter referred to as a second imaging angle adjusting mode), the microprocessor 13 inputs the adjustment value to the adjusting device 17, which The adjustment device 17 adjusts the photographing angle of the photographing unit 10 according to the adjustment value, so as to prevent the photographing unit 10 from deflecting relative to the gravity field, thereby obtaining a correct image frame. The unadjusted image and the adjustment value can also pass through the adjustment image. The transmitting unit 16 is sent to an external device connected to the camera device, such as a personal computer, and the image processing software in the external device processes the image by using the adjustment value. [0014] Referring to FIG. 2, another camera device of the present invention is used. In a preferred embodiment, the selection unit 12 can also be connected only to the microprocessor 13 and not to the data processing unit 11 and the adjustment device 17.

Referring to FIG. 3, a preferred embodiment of the method for adjusting the imaging angle of the camera device of the present invention comprises the following steps: Step S31, storing a standard value into the memory unit 14. In step S32, the gravity sensor 15 senses the relative position between the camera and the gravity field and outputs an adjustment signal. In step S33, the microprocessor 13 outputs an adjustment value after comparing the adjustment signal with the standard value. In step S34, the microprocessor 13 determines whether the imaging angle of the imaging device needs to be adjusted by using the magnitude of the adjustment value. If the imaging angle of the imaging device needs to be adjusted, step S35 is performed; otherwise, the process returns to step S32, step S35. The microprocessor 13 determines the imaging angle adjustment mode selected by the selection unit 12. When the selection unit 12 selects the first imaging angle adjustment mode, step S36 is performed, and the selection unit 12 selects the second imaging angle adjustment. In the case, step S37 is performed. In step S36, the microprocessor 13 transmits the adjustment value to the data processing list form number Α0101, page 9 / page 17 0982016672-0 201036430, and the data processing unit 11 adjusts the image according to the adjustment value to obtain the correct value.

The photographing angle of the photographing unit 10 is such that the photographing unit 10 does not deflect relative to the gravitational field, thereby obtaining a correct image plane. The camera device can be applied to various electronic devices such as personal computers, mobile phones, cameras, and cameras. When the image is rotated by the deflection of the camera device, the gravity sensor 15 outputs an adjustment signal, and the microprocessor 13 obtains the adjustment value by using the adjustment signal and the standard value in the memory unit 14, and transmits the adjustment value through the adjustment device. 17 or the data processing unit 11 correspondingly adjusts the imaging angle of the photographing unit 10 or the obtained image, which is not only easy to operate but also has high precision.
