METHOD AND APPARATUS FOR DETERMINING PHASE DIFFERENCE

A method and apparatus for determining a phase difference. The method comprises: acquiring a first image shot by a camera at a first position, and acquiring a second image shot by the camera at a second position (S102); and determining a phase difference between the first image and the second image according to first pixel information about the first image and second pixel information about the second image (S104). The problems in the relevant technology that it is necessary to sacrifice an original pixel of an image sensor or an additional camera needs to be added when a camera acquires phase information are solved, so that the camera can not only complete phase focus, but also ensure the imaging quality, without an additional camera. L'invention concerne un procédé et un appareil de détermination d'une différence de phase. Le procédé consiste : à acquérir une première image prise par une caméra dans une première position et à acquérir une seconde image prise par la caméra dans une seconde position (S102) ;
