Photographing device and method

The invention relates to a photographing device and method.

With the continuous development of electronic technology, more and more electronic devices can be used for photographing, such as mobile phones, digital cameras, PDAs, etc. However, when users use these camera devices to take photos, the following two problems occur in the photos taken. : (1) The photographs taken are blurred and unclear; (2) the photographs taken are not particularly correct, and are even significantly skewed.

The above two problems are important factors affecting the visual effect of the whole photo. The main reason for the problem (1) is that when the user clicks the camera button of the camera device to take a photo, the camera device will be shaken, resulting in a blurred photo. To solve this problem, you can use the method of time-lapse photographing, that is, not taking pictures immediately after clicking the photo button, but taking a photo after a few seconds. The main reason for the problem (2) is that the photo device is deflected left and right during the photographing process, which causes the photographed photograph to be skewed, and the photo blurring problem is solved by the time-lapse photographing method, but it cannot Solve the problem of skewed photos.

In view of the above, it is necessary to provide a photographing device that prevents the photograph taken by the photographing device from being skewed.

It is also necessary to provide a photographing method which can prevent the photo taken by the photographing device Skewed.

The photographing method is applied to the photographing device, and comprises the steps of: (a1) detecting the angle of the left and right deflection of the photographing device when the photographing device performs photographing in the anti-skew photographing mode; (a2) when the photographing device takes a photo When the button is pressed, the timer for starting the photographing device starts counting; (a3) determining whether the deflection angle of the photographing device to the left or the right is greater than the left and right deflection allowed by the photographing device to take a photograph in the anti-skew photographing mode. If the maximum angle value is greater than, the step (a5) is performed; otherwise, the step (a4) is performed; (a4) determining whether the timer time of the timer reaches the photographing delay time of the photographing device, and if so, executing the step ( A6), otherwise, returning to step (a3); (a5) clearing the timer value of the timer, terminating the photographing, and ending the flow; (a6) the photographing device performs photographing.

Compared with the prior art, the photographing device and method can be provided to a user to take a photograph in an anti-skew photographing mode by using the photographing device, thereby preventing photographs taken due to the left and right deflection of the photographing device during photographing.
