Abstract

The embodiment of the invention provides a method for automatically switching a focus mode of a terminal and the terminal, relating to the field of the terminals, and aiming at determining the focus mode of the terminal more effectively. The method comprises the following steps: acquiring an image data frame; and switching the focus mode of the terminal according to a brightness value of a photometric area of the image data frame. The terminal comprises a sensor unit, an imaging unit and a display unit, wherein the imaging unit comprises a data frame acquisition module that is used for acquiring the image data frame, and an automatic focus control switching module that is used for switching the focus mode of the terminal according to the brightness value of the photometric area of the image data frame.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a method for automatically switching terminal focusing modes and a terminal. Background technique [0002] The working mode of modern camera autofocus system is mainly divided into single autofocus, continuous autofocus and intelligent autofocus. [0003] The working process of one-shot AF is started by half-pressing the shutter, and the focusing process continues until the focus is not accurate. Once the processor thinks that the focus is accurate, as long as the shutter is fully pressed, a shooting process is completed, and the autofocus system stops working at the same time. If the subject or the camera moves before the shutter button is fully pressed after the focus completes the beep. Since it is "single-shot" autofocus, you may see an unclear picture after fully pressing the shutter. Due to the characteristics of single-shot autofocus, it is the most suitable choice when...
