Abstract

The invention is suitable for the computer field, and provides a lens focal length adjusting method and a lens focal length adjusting device, which are used for an intelligent terminal. The intelligent terminal comprises a pressure touch control module disposed on a frame. The lens focal length adjusting method comprises steps that touch control operation input by a user via the pressure touch control module is received; a lens focal length adjusting rule corresponding to the touch control operation is acquired according to a corresponding relation between the preset touch control operation and the lens focal length adjusting rule; the focal length of the lens is adjusted according to the acquired lens focal length adjusting rule. The intelligent terminal is used to receive the touch control operation input by the user via the pressure touch control module disposed on the frame, and the lens focal length adjusting rule corresponding to the touch control operation is acquired according to a corresponding relation between the preset touch control operation and the lens focal length adjusting rule, and is used to adjust the lens focal lens, and therefore the user can simply and conveniently adjust the focal length of the lens by making the touch control operation via a single hand, an adjusting process is humanized, and problems of conventional intelligent terminal lens focal length adjustment such as requirement on both-hand operation of user, tedious operation, and poor user experience are solved.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a method and a device for adjusting the focal length of a lens. Background technique [0002] With the development of science and the improvement of people's living standards, smart terminals with cameras such as mobile phones and tablet computers are widely used in people's daily life. Di, especially the Selfie function brought by the front camera is deeply loved by the majority of users, especially female users who love beauty. [0003] When the smart terminal takes pictures and videos, the focal length of the lens is closely related to the imaging effect, and a suitable focal length means a clearer and satisfactory imaging effect. Therefore, the adjustment of the focal length of the lens of the smart terminal is indispensable. [0004] However, in the current smart terminal, it is difficult to adjust the focal length of the lens with one hand. It is necessary for the user...
