Embodiment Construction

[0050] In order to have a better understanding of the above and other aspects of the present invention, preferred embodiments will be described in detail below together with the accompanying drawings.

[0051] Please refer to figure 1 , which is a flow chart of a control method of a camera device according to an embodiment of the present invention. This control method includes several steps. In step S110, the camera device enters into a preset automatic camera mode. In step S120, a shutter speed is determined by the camera device according to the moving speed of an object in a preview window of the camera device. In step S130, the camera device determines an aperture according to a depth of field of the object in the shooting direction of the camera device. In step S140, the camera device determines whether the exposure amount corresponding to the camera device is sufficient under the combination of shutter speed and aperture. In step S150 , when the exposure amount is suf...

Abstract

The invention discloses a photographic device and a control method thereof. The control method comprises the following steps that the photographic device is enabled to enter a preset automatic photographic mode; the photographic device determines a shutter speed according to the moving speed of an object in a preview window of the photographic device; the photographic device determines an aperture according to a field depth of the object in the shooting direction of the photographic device; the photographic device judges whether exposure corresponding to the photographic device under the combination of the shutter speed and the aperture is enough or not; and if the exposure is enough, the photographic device makes a response to a shooting command to conduct shooting according to the shutter speed and the aperture. In order to taking pictures with a field depth effect, various shooting parameters such as the shutter speed and the aperture can be respectively determined in the preset automatic photographic mode. Therefore, the photographic device is simple and convenient to use by a user and the quality of taken pictures can be improved through the proper shutter speed and the proper aperture.

Description

technical field [0001] The present invention relates to an electronic device and its control method, and in particular to a camera device and its control method. Background technique [0002] The camera focuses the external image on the film or image sensor chip through the lens, so that the image can be stored permanently. In the development process of cameras, they are divided into consumer cameras and single-eye cameras. The difference between the two lies in the setting of some shooting parameters, such as aperture or shutter speed. [0003] Generally speaking, by manually setting these shooting parameters, the quality of the image captured by the monocular camera can be improved. However, based on the principle of camera imaging, the setting of shooting parameters is quite complicated. For users who are generally not professionals, the setting of these shooting parameters often causes troubles for users. For example, in order to produce a photo with a depth-of-field e...
