Abstract

Provided are a method for automatically switching a terminal focusing mode and a terminal, which relate to the field of terminals, and can more effectively determine a focusing mode of a terminal. The method comprises: acquiring an image data frame; and according to a brightness value of a photometric region of the image data frame, switching a focusing mode of the terminal. The terminal comprises a sensor unit, an imaging unit and a display unit, wherein the imaging unit comprises a data frame acquisition module which is used for acquiring an image data frame, and an automatic focusing control switching module which is used for switching a focusing mode of the terminal according to a brightness value of a photometric region 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...
