Abstract
A bidirectional screen alternately switches between a display mode showing conventional graphics and a capture mode in which the LCD backlight is disabled and the LCD displays a pinhole array or a tiled-broadband code. A large-format image sensor is placed behind the liquid crystal layer. Together, the image sensor and LCD function as a mask-based light field camera, capturing an array of images equivalent to that produced by an array of cameras spanning the display surface. The recovered multi-view orthographic imagery is used to passively estimate the depth of scene points from focus.
