Abstract

The invention provides a focusing system of a digital camera. The system comprises a receiving module, a focusing module, a judging module and a selection module, wherein the receiving module is used for receiving a focusing mode selected by a user; the focusing module is used for focusing when the user semi-presses a shutter according to the focusing mode selected by the user; the judging module is used for judging whether the focusing is successful; the selection module is used for automatically reselecting the most proper focusing mode when the focusing is failed; and the focusing module is also used for completing the focusing according to the selected most proper focusing mode when the focusing is failed. The invention also provides a method for focusing the digital camera. The focusing system can automatically and accurately select the most proper focusing mode for focusing under the condition that the user improperly selects the focusing mode.

Description

technical field [0001] The invention relates to a digital camera focusing system and method. Background technique [0002] The focus of a digital camera refers to controlling the sharpness of the object image when shooting by moving the lens according to the optical principle. [0003] At present, most digital cameras use three Focus Modes: Auto Mode (automatic mode), Macro Mode (short distance mode) and Infinity Mode (long distance mode). Each of these focusing modes corresponds to a range of lens movement. After the user selects a focus mode, the lens only moves within the range corresponding to the focus mode, thereby shortening the focus time of the digital camera during shooting. [0004] In this way, the user needs to select a Focus Mode from the above-mentioned focus modes before each shooting, but some users often fail to focus and take pictures unclearly due to improper selection of the Focus Mode. Contents of the invention [0005] In view of the above, it is ...
