Method for realizing shift photography and three-dimensional multi-region automatic focusing through touch screen operation

Abstract

The invention discloses a method for realizing shift photography and three-dimensional multi-region automatic focusing through touch screen operation. The method for realizing the shift photography and the three-dimensional multi-region automatic focusing through the touch screen operation includes the following steps: A, using a camera lens to gather an image of a shot object, converting into an electric signal through an image sensor, and displaying on a touch display screen; B, enabling an operator to choose a focus point through the touch screen; C, enabling the camera lens to automatically choose an offset direction, or enabling the operator finger to slide on the touch screen to indicate a camera lens deflecting direction; D, automatically focusing in Z-axis; E, automatically focusing in Rx-axis and Ry-axis. Through operating on the touchpad, the method for realizing the shift photography and the three-dimensional multi-region automatic focusing realizes the three-dimensional automatic focusing in different depths of fields selected by the operator on the touch screen through controlling the move of the camera lens according to the chose interested object region, and moreover, the method realizes the automatic focusing for the interested object region through choosing on the touch screen, and the focusing is more convenient to realize, is more precise, does not need training, and is more interesting and so on.

Description

technical field [0001] The invention discloses a lens focusing method, in particular a method for realizing axis-shifting photography and 3-dimensional multi-zone automatic focusing through touch screen operation. Background technique [0002] With the development of micro-cameras and the emergence of highly integrated micro-OIS technology, the realization of micro-cameras with a pixel resolution of 5 million and higher on touch-screen mobile phones, tablet computers and other portable devices has made the camera effect of mobile phones more and more effective. The closer it is to a digital camera, the closer it is to the function of a large camera device, such as optical image stabilization (OIS) through translation or rotation of the lens, etc. (see patent: PCT / CN2008 / 072680). Many internationally renowned micro-integrated camera manufacturers have successively launched cameras with optical image stabilization focusing motors based on lens rotation, and have gradually ...

Problems solved by technology

[0004] Aiming at the above-mentioned shortcoming that the micro-camera in the prior art cannot achieve multi-point simultaneous focusing, the present invention provides a smart phone or a portable tablet equipped with a micro-integrated camera with a touch-screen operation interface and a lens rotation optical anti-shake function. On such devices, the method of manipulating the lens by operating the touch screen interface to obtain clear focus or obtain other special oblique photography effects at the same time when shooting several objects of interest with different distances in a frame, which is combined with lens rotation optics The micro-integrated camera with anti-shake function and the touch-screen technology commonly used in smart phones and tablet computers at present, use the touch-screen interface to operate the micro-integrated camera with lens rotation function to achieve multi-point simultaneous focusing
