摘要： Various image capture control methods and apparatuses are disclosed. An image sensing unit can be inclined relative to an initial normal line, to change a ratio of pixels distributed along two directions in an effective region of the image sensing unit in which light through a lens that is in an imaging system and corresponds to the image sensing unit is imaged on the image sensing unit. The two directions are perpendicular to the initial normal line and orthogonal to each other, the image sensing unit comprises pixels distributed in array, and the pixels are used for recording multidirectional view information of a same object of a scene. An image of the scene is captured using the imaging system. Proportions of parallax information actually recorded by the image sensing unit in the two directions can be changed, and differential capture of view information in different directions can be implemented.

摘要： An imaging adjustment apparatus includes: an imaging analysis module, used to determine whether a current image of an object is deformed relative to an original image of the object, and when the current image is deformed, generate imaging correction information corresponding to the deformation; an imaging lens group, used to image the object, and including a plurality of subregions having adjustable imaging parameters; and a lens adjustment module, used to adjust an imaging parameter of a corresponding subregion of the imaging lens group according to the imaging correction information. An object can be imaged by using an imaging lens in which each subregion has adjustable imaging parameters, so as to adjust the imaging parameters for each subregion separately, thereby adjusting and correcting a perspective deformation that occurs on the object, preventing a perspective deformation from occurring on an image of the object acquired by a user, and improving user experience.
