Description of the Invention: [Technical Field] The present invention is directed to a crane image method, which is a dynamic image capturing method. [Prior Art] Since the conventional camera is shooting, in order to obtain better image quality for the captured image, the system needs to adjust the aperture, shutter, etc. of the conventional camera in accordance with the shooting environment to adjust the exposure time. To shoot images without problems such as underexposure or overexposure. • Since the traditional camera needs to adjust the aperture and shutter with the shooting environment, the user can't adjust the shooting environment (4) aperture and shutter parameters, which causes many problems. With the rise of digital devices, digital cameras have gradually replaced mobile phones in the market due to the portability of digital cameras. When the user causes the position camera to take a moving object, the digital camera's built-in _ state detection function will take the method of taking the ISO value or reducing the exposure time after the _ to the moving object. Avoid problems such as blurring or image sticking of the image of the subject. However, the higher the value of the sensitivity (Intemati()nalIZationforStodardizati〇n, ISO), the more the noise of the resulting object image becomes more serious, which causes the user to increase the IS threshold to avoid image sticking. But sacrificed the image of the captured image f. On the other hand, the use of speeding up the door speed and shouting less exposure when the method of f is used in a dim environment, when the exposure is reduced, the brightness of the environment is too dark to be properly exposed, instead the image is taken because Underexposure reduces image quality. 201103314 SUMMARY OF THE INVENTION The present invention provides a dynamic image capturing method for avoiding blurring of an image of a captured object by adopting a method of increasing the sensitivity (International Organization for Standardization) or reducing the exposure time. Problems such as afterimages have caused serious problems with image noise and underexposure. The motion picture capturing method according to the present invention can be applied to an image pickup apparatus. First, 'detect the subject system as dynamic. Next, calculate the moving speed of the subject. Then, the ratio of the moving speed to the threshold value is used to start the flash of the camera. The threshold value can be preset and stored in the camera. In this case, when the camera detects that the subject is dynamic, it can also perform a tuning for capturing the image of the subject, and when the moving speed is greater than the threshold, the camera is accommodating the image. _ At the same time, the age of the lights to assist in the filming of gifts. Where 'the camera parameters can include aperture value, sensitivity and exposure time. The step of calculating the moving speed of the object may be to calculate an average value of the speed of the object. The comparison movement speed and the door record (4) can be compared with the average value of the moving speed and the threshold value. According to the illuminating exposure, the image capturing method should be on the camera. When the gamma camera is used to compose an object, the scale camera will check to see if the body is dynamic. When it is confirmed that the subject is dynamic, the camera is flexed and the moving speed of the subject is different. Next, the camera will set the camera's Wei speed and _image device according to the 201103314 and set the camera to __, which is based on the county's flash. The dynamic image capturing method disclosed in the present invention can pass the flash = lamp to avoid sacrificing the shooting 4 because the value of IS0 is increased. At the same time, it is possible to reduce the exposure time by starting the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Regarding the features and implementations of the present invention, the preferred embodiment of the present invention is described in detail below. [Embodiment] "First FIG. 1" is a schematic diagram of a photographic image of a photographic image according to the present invention; and "2nd drawing" is an imaging device of the moving image method of the present invention. Please refer to "Fig. 1" and "Fig. 2", and the dynamic image capturing method according to the present invention can be applied to the image pickup apparatus 100. In this embodiment, the motion picture capture includes: First, 'detecting the subject as dynamic (step 21). Next, the moving speed of the subject is calculated (step 22). Then, the moving speed and the homing value are compared (step (1). Finally, the camera light is activated according to the comparison result of the moving speed and the threshold value (step 24). The threshold value can be preset and stored in the camera unit 〇 Please refer to "Fig. 2". The imaging device 100 may include a processing module 2, a storage unit 30, a camera module 40, and a flash unit 5. 201103314 When the user uses the camera device (such as a digital camera) An electronic device having a camera function such as a digital camera. When an object of a dynamic (such as a movement with a vector shift such as moving, rotating, shaking, etc.) is to be photographed, the shirt directly causes the automatic mode of the video device 100 (Aut() M (Xle) to capture the image of the subject. However, the automatic mode of the camera sets the values of the imaging parameters such as aperture, hiccup and sensation, and the miscellaneous causes (4) when the dynamic crane object is shot due to insufficient exposure or If the sensitivity is too low, the image of the crane object that is left behind may have poor image quality, etc. On the other hand, if the user wants to take a secondary subject, When the camera is dynamically adjusted to the dynamic mode (coffee. _. &), this action may cause the user to miss the optimal shooting opportunity. Therefore, according to the moving image capturing method of the present invention, when the user uses the camera When the device 100 is to capture a moving subject, the user can first focus on the subject through the camera module 40 of the imaging device, and the function of the dynamic _ (MGtiGn DeteetiGn) just built in the imaging device is used. Whether the forehead object is dynamic (such as movement, rotation, shaking, etc. with vector displacement) (step 21). When the dynamic side function built in the camera device 100 determines that the subject system is in the dynamic state, then, The processing module 2 in the imaging device should calculate the moving speed or moving speed of the subject based on the subject image continuously captured by the imaging module 40 of the imaging device (step 22). The processing module in 100 calculates the average value of the moving speed or moving speed of the object, and then the processing module '2() according to the calculated object The average silk image of the crane speed difference is set and stored in the storage unit to compare the values (step 23). 201103314 Finally, the paving catch and the Η槛 are worth more than the county, when the moving speed is greater than the = value The flash 50 of the camera device 100 is activated. When the moving speed is less than the threshold value, the flashing of the flashing camera 5 is not performed (step 24). The dynamic image capturing method of the embodiment further includes: After detecting that the subject is dynamic (step 21), adjust the imaging parameters of the camera (step 25), for example: the value of the International Organization for standardization (ISO), reduce the exposure time, or switch to a large aperture. . In other words, when the dynamic function built in the imaging device 100 determines that the subject system is dynamic, that is, when the imaging device 100 is to perform dynamic photography, the processing module 20 within the imaging device automatically adjusts the imaging parameters of the imaging device 1〇〇. (such as: increase the shame value, reduce the exposure time or switch to a large aperture, etc.) to reduce the image of the captured subject due to the movement of the subject, and blur or afterimages occur. The imaging parameters may include: an IS threshold, an aperture value, and an exposure time. Therefore, the motion picture capturing method of the present invention can be built in the storage unit 3 of the image capturing apparatus 100 through a software or a firmware program, and then implemented by the software or the physical program of the image processing. The silk image capturing method of the present invention. In this embodiment, when the user uses the image pickup device 1 to photograph an object, the image pickup device 1GG at this time first confirms that the subject is in a state in which S is dynamic. When it is confirmed that the subject is dynamic, the processing module 2 within the imaging device 1 automatically adjusts the parameters of the imaging device 100 to increase the ISO value, switch to a large aperture, and reduce the exposure time. At the same time, the camera unit 1 is made to calculate the moving speed of the subject. Next, the imaging apparatus 100 performs a comparison based on the calculated moving speed of the subject and a threshold value set in advance and stored in the imaging apparatus 100. When the comparison speed is higher than the threshold value, the camera device 100 activates the flashing light of the camera device 100 while adjusting the imaging parameters (wherein, the flash is illuminated by the flash 5 On the object, the effect of suppressing the image sticking is achieved by increasing the IS threshold and reducing the exposure time. The dynamic image capturing method according to the present invention is applied to the image capturing device, so that the camera device can determine the timing of turning on the flash to avoid improvement.
