Multiframe reconstruction combines a set of acquired images into a reconstructed image. Here, which images to acquire are selected based at least in part on the content of previously acquired images. In one approach, a set of at least three images of an object are acquired at different acquisition settings. For at least one of the images in the set, the acquisition setting for the image is determined based at least in part on the content of previously acquired images. Multiframe image reconstruction, preferably via a multi-focal display, is applied to the set of acquired images to synthesize a reconstructed image of the object.

Adaptive image acquisition and display using multi-focal display

A multi-focal display represents a 3-dimensional scene by a series of 2-dimensional images located at different focal planes. The locations of the focal planes are selected based on an analysis of the three-dimensional scene to be rendered by the multi-focal display.

Content-adaptive multi-focal display

A multifocal display for rendering a 3D scene as a series of 2D images. In one aspect, the multifocal display includes a display, an optical imaging system, a refractive focus actuator and a controller. The display renders the 2D images. The optical imaging system is image-side telecentric and creates an image of the display. The refractive focus actuator is positioned at the pupil of the optical imaging system. Thus, adjusting the refractive focus actuator alters a location of the image of the display but does not significantly alter a size of the image. The controller coordinates adjustment of the refractive focus actuator with rendering of the 2D images on the display. The waveform driving the focus actuator is preferably designed to reduce ringing and jitter effects.
