Field of the Invention The present invention relates to the field of imaging, and more particularly to an image pickup apparatus and an image automatic erect method thereof. [Prior Art] In today's information age, various camera devices, such as digital cameras, digital cameras, and mobile phones with camera functions, are increasingly favored by consumers, and the functions of camera devices are increasing. When a conventional camera device is used for shooting, the camera device is generally fixed by a hand or a tripod. The camera may be tilted due to the possibility of jitter or uneven placement of the tripod during shooting, causing the subject to be in the subject. The imaging on the camera is tilted. Thus, directly storing the image of the subject is obviously not conducive to viewing in the future. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an image pickup apparatus capable of automatically erecting an image of an object which is tilted at the time of shooting, and an image automatic erect method. A camera device includes a sensor, an image sensor, an image processing unit, and a memory. The sensor, the image sensor, and the memory are electrically connected to the image processing unit, respectively. The image sensor is used to acquire an image of a subject. The sensor is configured to sense an inclination of the image capturing device to acquire an image of a subject. The image processing unit corrects the subject image to an image of the subject that is erected according to the tilt. The memory is used to store an image of the corrected subject. 6 200913685 An image auto-aligning method for a camera device, comprising the steps of: acquiring an image of a subject, and sensing tilt information when the camera device acquires an image of the subject; according to the tilt of the camera device Degree information, correcting the image of the subject to obtain a picture with an erect object image; and storing the picture with the erect object image. The camera device obtains the tilt information at the same time as the image of the subject, and then corrects the image of the tilted object by the tilt information to obtain an erect object image, and then Store it again for later viewing. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. FIG. 1 is a functional block diagram of a camera device 100 according to an embodiment of the present invention. The camera device 100 includes a sensor 10, an image sensor 20, an image processing unit 30, a memory 40, and a display 50. The sensor 10, the image sensor 20, the memory 40, and a display 50 are electrically connected to the image processing unit 30, respectively. The camera device 100 may specifically be a digital camera, a digital camera, a mobile phone having an imaging function, or the like. When the image pickup apparatus 100 is in an ideal photographing state, the axis is generally perpendicular to the horizontal plane to capture an erect image. However, in actual shooting, the camera device 100 tends to be inclined, that is, the axis thereof often has a certain angle with the normal of the horizontal plane, and the image of the object obtained by the camera device 1 tends to be inclined. image. The image sensor 20 is configured to acquire an image of the object and convert the optical signal from the object of the 200913685 into an electrical signal corresponding to the image of the object. When the tilt occurs when the image pickup apparatus 100 is photographed, the image of the subject on the image sensor 20 is also tilted to obtain the first picture 101 as shown in FIG. In general, the tilt angle of the camera is set to be the same as the tilt angle and direction of the image on the image sensor 2 . In the present embodiment, the subject is a tree. Since the camera 1 is tilted at the time of shooting, the tree appears tilted in the first picture 1〇1. The sensor 10 is configured to sense the slope of the camera of the camera device 1 , that is, the refresh angle between the axis of the camera device 1 and the normal of the horizontal plane. A signal reflecting the inclination of the imaging device 100 is emitted. The normal line of the good plane is the same as the direction of the gravitational acceleration. By the angle between the central axis of the sensing image f and the gravitational acceleration, it can be known that the image is between the central axis of the 100 and the normal of the horizontal plane. The angle is obtained to obtain the inclination of the image capturing device 100 when the image is captured. The angle between the sensing camera line and the gravitational acceleration can be easily realized, such as an h-spin or a multi-axis sensing element. The image processing unit 3 is configured to correct the image of the object captured by the image sensor 2 to an image of the object that is erect. Please refer to FIG. 2 = FIG. 4 'specifically' the image processing unit 3 得到 according to the inclination signal of the imaging device 1 GG of the sensor i 1 , and obtain the inclination angle of the image of the object 2: The tilt angle of the subject image on the picture 101. By rotating the first picture (10), the angle of the tilting angle of the camera is the same as the angle of the opposite direction, and the image is transmitted to the second picture. The subject image is positive in the 8th 200913685 2 picture 102. Standing. However, the second picture 102 is not an erect rectangle. Preferably, the second picture 102 is clipped to obtain an erect third picture 103. Since the imaging device 100 is often tilted when actually shooting, the smaller tilt does not affect the viewing effect of the formed picture. Therefore, preferably, the image processing unit 30 sets a field value. When it is detected that the inclination of the imaging apparatus 100 is greater than the threshold value, the subject image is corrected, otherwise the correction is not performed. The memory 40 is used for storage after being processed by the image processing unit 30. A picture, such as the third picture 103. The display 50 can be used to preview a subject image during shooting of the image pickup apparatus 100, and can also be used to view a picture stored in the memory 40 during non-shooting. In addition, an embodiment of the present invention further provides an image auto-aligning method of the image capturing apparatus 100. It includes the following steps, please refer to Figure 5. Step S11: Acquire an image of a subject to obtain an original picture having an image of the subject, and sense the inclination of the image capturing device 1 to acquire the image of the subject. The inclination of the image pickup device 1 specifically reflects the angle between the axis of the image pickup device 100 and the normal to the horizontal plane. The tilt of the camera device 100 can be sensed by a sensor 10 fixed to the camera device 100. The sensor 10 can be a gyroscope. Step S13: Correcting the image of the subject according to the tilt information of the image capturing apparatus 1 (8) to obtain a picture 9 200913685 having an image of the object being erected. In step S13, a determining step may be further included to determine whether the tilt of the camera is greater than a set value, and if it is greater than, the subject image is corrected, otherwise the correction is not performed. Step S15: storing the picture having the erect object image. The camera device obtains the tilt information at the same time as the image of the subject, and then corrects the image of the tilted object by the tilt information to obtain an erect object image, and then Store it again for later viewing.

However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
