Abstract
Embodiments of the present application disclose various methods and an apparatus for controlling light field capture. One method for controlling light field capture comprises: determining, at least according to at least one sub-lens that affects imaging of a first region in a sub-lens array of a light field camera, at least one first sub-lens to be adjusted, the first region being a part of a scene to be shot; determining an object refocusing accuracy of a light field image section captured by the first sub-lens in a light field image of the scene to be shot; adjusting, according to the object refocusing accuracy, a light field capture parameter of the first sub-lens; and performing, based on the light field camera after being adjusted, light field capture on the scene to be shot. The solution can achieve differentiated distribution of refocusing accuracies of various light field image sections that correspond to different regions of the scene to be shot, thereby better satisfying a user's actual application demands.
