Embodiment Construction

[0043] like figure 1 As shown, the present embodiment utilizes the existing hardware structure. During the shooting process of the rear camera 04, the front camera 05 continuously collects the center of the pupil when the mobile phone holder is watching the focus of vision in the display screen. The central processor 07 converts the coordinates of the pupil center position into the position coordinates of the visual focus in the frame of reference of the rear camera 04, and the central processor 07 sends corresponding zooming to the rear camera 04 according to the change of the coordinates of the visual focus position The control signal continuously changes the focus position of the rear camera 04.

[0044] The physical structure of the mobile phone must determine the relative positional relationship of the display screen 03, the front camera 05, and the rear camera 04, so that the display frame of reference, the front camera frame of reference, and the rear camera frame of re...

Abstract

The invention provides a mobile phone shooting focusing method, which is executed in a smart mobile phone with a front camera and a back camera. In the back-camera shooting process, the method comprises the following steps that 1, the position coordinates of pupil centers in a front camera reference system when a mobile phone holder watches a visual focus in a display screen are collected through the front camera; 2, a central processing unit converts the position coordinates of the pupil centers into the position coordinates of the visual focus in a back camera reference system; 3, the central processing unit sends corresponding zooming control signals to the back camera according to the change of the position coordinates of the visual focus, and the focusing positions of the back camera are changed; the operation is repeated from the first step to the third step. The focusing imaging quality of the smart mobile phone is greatly improved. Meanwhile, the vibration influence of the manual focusing on the shutter response is avoided.

Description

technical field [0001] The present invention relates to a focusing method of photographic equipment, in particular to a focusing method of photographic equipment utilizing physiological characteristics. Background technique [0002] Nowadays, smart phones are used more and more widely, and the functions included are becoming more and more intelligent. It can be predicted that intelligent operations will receive more and more attention on mobile phones. [0003] The combination of camera and mobile phone has become commonplace and has been optimized more and more over the past period of time. However, the relatively intelligent functions are still limited and cannot meet the needs of users. For mobile phones with forward-facing lenses and rear-facing lenses, the use of hardware devices has not been effectively developed, and is limited to the usual calls of limited software, and the devices are mostly in an idle state. [0004] When using a smartphone to take pictures, the...
