  • Patent number: 8305480
    Abstract: Algorithms and methods for performing electronic image formation and refinement from overlapping measurement vignettes captured by an array of image sensors and associated micro-optics are presented. The invention is directed to a new type of image formation system that combines readily-fabricated micro-optical structures, a two-dimensional image sensor array with electronic or digital image processing to actually construct the image. Image formation is performed without a conventional large shared lens and associated separation distance between lens and image sensor, resulting in a “lensless camera.” In an application, a readily fabricatable LED array is used as a light-field sensor. In an application, the LED array further serves as a color “lensless camera.” In an application, the LED array also serves as an image display. In an application, the LED array further serves as a color image display. In an embodiment, one or more synergistic features of an integrated camera/display surface are realized.

  • Publication number: 20120267512
    Abstract: Methods of implementing light field sensors for lensless synthetic imaging is provided. Relatively tall and short structures are fabricated, wherein the short structures comprise light sensing capabilities. The tall structures and short structures are arranged in an array to create an array of vignetted light sensors that partition an incoming light field into a plurality of vignetted light fields, each uniquely associated with a particular light sensor. Each light sensor generates a measurable electrical quantity responsive to the associated vignetted light field, and the collective measurable electrical quantities are responsive to incoming light field. The short structures can comprise photodiodes, LEDs, or OLEDs, and the resulting light field sensor can respond to color. Tall structures can comprise electronic components, LEDs, OLEDS, or OLETs.

  • Publication number: 20120006978
    Abstract: A system for implementing a display which also serves as one or more of a tactile user interface touchscreen, light field sensor, proximate hand gesture sensor, and lensless imaging camera. In an implementation, an OLED array can be used for light sensing as well as light emission functions. In one implementation a single OLED array is used as the only optoelectronic user interface element in the system. In another implementation two OLED arrays are used, each performing and/or optimized from different functions. In another implementation, an LCD and an OLED array are used in various configurations. The resulting arrangements allow for sharing of both optoelectric devices as well as associated electronics and computational processors, and are accordingly advantageous for use in handheld devices such as cellphone, smartphones, PDAs, tablet computers, and other such devices.
