Abstract

The invention discloses an image photographing parameter adjusting method and device. The method comprises the steps that a vibration signal generated by a user through tapping a mobile terminal is acquired in image photographing; the vibration signal is matched with a preset signal sample; entering a corresponding adjusting mode is performed when consistency of the vibration signal and the preset signal sample is determined; and an image photographing area is zoomed or reduced based on the adjusting mode. When the user performs image photographing, the action of tapping the mobile phone of the user is identified by the vibration signal so that the image photographing area is zoomed or reduced according to the vibration signal without using physical buttons, adjusting operation is simplified for the user, adjustment of the image photographing area is easier and more convenient in the image photographing process in comparison with the methods in the prior art, and thus operation efficiency and operation flexibility of adjustment can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for adjusting camera parameters. Background technique [0002] With the rapid development of mobile communication technology, mobile terminals (such as mobile phones, tablet computers, etc.) have more and more functions; for example, users can use mobile terminals to take pictures. [0003] During the shooting process, due to the different needs of each person, the camera parameters (such as resolution, focal length, white balance, etc.) automatically adjusted by the mobile terminal may not meet the individual needs of the user, so the user can adjust the camera parameters according to the needs. For adjustment, for example, if the user needs to zoom in or out of the object being photographed, that is, when the object being photographed is zoomed in or out, a physical button for volume adjustment is required or the user needs to use screen ...
