The invention provides a shooting method and a mobile terminal, which solves the problem that the current lifting camera is difficult to automatically track images. The shooting method of the present invention includes: detecting that the viewfinder lens protrudes from the casing through the opening, determining the object to be photographed; acquiring the position and image of the object to be photographed within a preset time period before the target moment The target angle between the preset positions of the sensor, the target moment is the moment when each image frame is generated according to the subject; when the target angle is different from the preset angle, by controlling the rotation of the viewfinder lens, the The target angle is adjusted to the preset angle; the subject is photographed to generate the image frame. In the embodiment of the present invention, by rotating the viewfinder lens, when shooting each image frame, the target angle between the position of the subject and the preset position of the image sensor can be guaranteed to be a preset angle, so as to realize real-time tracking of the subject.
Description
technical field [0001] The present invention relates to the technical field of communication applications, in particular to a photographing method and a mobile terminal. Background technique [0002] With the development and progress of smart phones, mobile phones have more and more functions. With the diversification of mobile phone functions, users have higher and higher requirements for the size of the mobile phone display; the increase in the size of the display screen has led to an increase in the size of the mobile phone, which has reached the limit size of the hand, and the shape will be enlarged The size will affect the user experience. Therefore, on the basis of a certain size, increasing the proportion of the display screen has become the development trend of increasing the display size. [0003] Among the various functions of mobile phones, the camera function is used very frequently. In order to realize the selfie function, a camera shooting window must be lef...
