Abstract
Embodiments of the present application disclose various light field display control methods and apparatus, and various light field display devices. One of the methods comprises: determining a first display region of a display of a light field display device according to target vision adjustment range information; adjusting display pixel density distribution of the display, to cause that display pixel density distribution of the first display region in the display after the adjustment is different from that of another display region of the display; performing sampling processing on a first light field image according to location information of display pixels of the display after the adjustment, the first light field image being corresponding to vision information in the target vision adjustment range and related to a source image; and displaying, by the light field display device after the adjustment, the first light field image undergone the sampling processing. The embodiments of the present application improve a vision correction precision of viewing an image by naked eyes for users having different vision information in a target vision adjustment range.
