Figure 2 is a block diagram showing another preferred embodiment of the image pickup apparatus of the present invention.

3 is a flow chart of a preferred embodiment of a method for adjusting an imaging angle of an image pickup apparatus of the present invention.

Referring to FIG. 1 , a preferred embodiment of the camera device of the present invention includes a camera unit 10 , a data processing unit 11 , a selection unit 12 , a microprocessor 13 , a memory unit 14 , a gravity sensor 15 , and a The transmitting unit 16 and an adjusting device 17. The photographing unit 10 includes a plurality of imaging lenses (not shown) and a charge coupled device (CCD) (not shown). The adjusting 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.

The camera 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 can have a value range of 0 degrees < α < 360 degrees or -180 degrees < α < 180 degrees. When the range of the adjustment signal is a positive real number set, the deflection angle θ of the camera relative to the gravity field to the right ranges from 0 degrees < θ < 180 degrees, and the camera device is leftward relative to the gravity field. The deflection angle θ ranges from 180 degrees < θ < 60 degrees; when the range of the adjustment signal is the whole real number set, the deflection angle θ of the camera relative to the gravity field to the right ranges from 0 degrees. <θ<180 degrees, the deflection angle θ of the imaging device to the left with respect to the gravity field ranges from -180 degrees < θ < 0 degrees.

The memory 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 value of the adjustment signal is a whole real number set, the standard value is 0 degrees, 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 mode can be changed according to actual needs. The sign of the adjustment value represents the direction of deflection of the camera relative to the gravitational field. For example, if the range of the adjustment signal is a positive real number set, and the standard value is 180 degrees, when the camera device is deflected to the right with respect to the gravity field, the deflection angle θ is less than 180 degrees, and the adjustment value is It is a negative angle value; when the camera device is deflected to the left with respect to the gravity field, the deflection angle θ is greater than 180 degrees, and the adjustment value 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 imaging device needs to be adjusted by the magnitude of the adjustment value. For example, when the standard value is 180 degrees and the adjustment value is obtained by subtracting the standard value from the adjustment signal, only when the deflection angle θ of the imaging device to the right with respect to the gravity field is 0 degrees or 360 degrees, that is, the adjustment When the value is -180 degrees or 180 degrees, the imaging angle of the camera does not need to be adjusted.

The selection unit 12 is for selecting an imaging angle adjustment mode. In the present embodiment, the selection unit 12 is a switching device, and the microprocessor 13 is selectively electrically connected to the adjustment device 17 or the data processing unit 11 through the selection unit 12. When the operator selects the microprocessor 13 to connect to the data processing unit 11 (hereinafter referred to as a first imaging angle adjustment mode), the microprocessor 13 inputs the adjustment value to the data processing unit 11, and the data processing unit 11 Adjusting the image according to the adjustment value to obtain a correct image frame; when the operator selects the microprocessor 13 to connect the adjustment device 17 (hereinafter referred to as a second imaging angle adjustment mode), the microprocessor 13 The adjustment value is input to the adjustment device 17, and the adjustment device 17 adjusts the photographing angle of the photographing unit 10 according to the adjustment value to prevent the photographing unit 10 from being deflected with respect to the gravity field, thereby obtaining a correct image frame. The unadjusted image and the adjustment value may also be sent to the external device connected to the camera through the transmitting unit 16, such as a personal computer, and the image processing software in the external device processes the image by using the adjustment value. .

Referring to FIG. 2, in another preferred embodiment of the camera device of the present invention, 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. The selection unit 12 can adopt various logic circuits. For example, when the selection unit 12 outputs a high level, the microprocessor 13 inputs the adjustment value to the data processing unit 11, and the first imaging angle adjustment is selected. In this manner, the data processing unit 11 will adjust the image according to the adjustment value; when the selection unit 12 outputs a low level, the microprocessor 13 inputs the adjustment value to the adjustment device 17, and then selects the first In the second imaging angle adjustment mode, the adjusting device 17 adjusts the shooting angle of the photographing unit 10 according to the adjustment value. The above adjustment values and standard values are not only angle values, but may be changed to other methods according to the needs of the designer.

In 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, when the selection unit 12 selects the second imaging. In the angle adjustment mode, step S37 is performed.

In step S36, the microprocessor 13 transmits 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.
