Patent number: 10216263Abstract: A display system includes a display alignment tracker configured track the position of a first signal in a first waveguide and the position of a second signal in a second waveguide. The display alignment tracker optically multiplexes a portion of a first signal and a portion of the second signal into a combined optical signal and measures a differential between the first signal and the second signal. The differential is used to adjust the position, dimensions, or a color attribute of the first signal relative to the second signal.Type: GrantFiled: September 12, 2016Date of Patent: February 26, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Steven John Robbins, Drew Edward Steedly, Michael Edward Samples, Zhiqiang Liu, Andrew K.

Patent number: 10178374Abstract: Examples are disclosed herein that are related to depth imaging of a 360-degree field of view. One example provides a depth imaging system comprising an image sensor, a reflector subsystem comprising one or more reflectors arranged to reflect a radial field of view of a surrounding environment toward the image sensor, a projector configured to project light onto the reflector subsystem for reflection into the surrounding environment, and a computing device comprising a logic subsystem and a storage subsystem comprising instructions executable by the logic subsystem to receive image data from the image sensor, and output a depth image based upon the image data.Type: GrantFiled: April 3, 2015Date of Patent: January 8, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Joshua Mark Hudman, Marshall T. DePue, Andrew K. Juenger

Publication number: 20150200220Abstract: Embodiments are disclosed that relate to image sensing systems configured to sense visible and infrared light. For example, one disclosed embodiment provides an image sensing system comprising an image sensor comprising a plurality of pixels, an optical path extending from an exterior of the image sensing system to the image sensor, and an infrared filter array positioned along the optical path. The infrared filter array is configured to transmit the infrared light to a first subset of pixels of the image sensor, and to filter at least a portion of the infrared light to reduce an amount of infrared light reaching a second subset of pixels of the image sensor relative to an amount of infrared light reaching the first subset of pixels.Type: ApplicationFiled: January 14, 2014Publication date: July 16, 2015Applicant: Microsoft CorporationInventors: Andrew K. Juenger, Prafulla Masalkar

Patent number: 5778106Abstract: A method and apparatus for processing an image captured by an image acquisition device having a two-dimensional matrix of non-square pixels with a first aspect ratio. In one aspect of the method, the image is sampled in a color sub-sampled manner such that fewer than three color measurements are known for each pixel location. A processed image is then constructed by processing the fewer than three color measurements known for each pixel to generate one or more interpolated color values at each of the pixel locations. A processed image is then created for rendering on an output device having a square raster with a second aspect ratio which differs from the first aspect ratio. The processed image is processed such that an aspect ratio of the original image captured on the non-square pixels is maintained on the output device.Type: GrantFiled: March 14, 1996Date of Patent: July 7, 1998Assignee: Polaroid CorporationInventors: Andrew K. Juenger, Werner Metz

Patent number: 5724456Abstract: A system and method for processing a digital image signal which represents an image can be made to optimally map luminance values versus a tonal reproduction capability of a destination application. Specifically, the system includes a device for partitioning the image into blocks, then combining certain blocks into sectors. An average luminance block value is determined for each block and a difference is determined between the maximum and minimum average luminance block values for each sector. If the difference exceeds a predetermined threshold value, then the sector is labeled as an active sector and an average luminance sector value is obtained from maximum and minimum average luminance block values.Type: GrantFiled: March 31, 1995Date of Patent: March 3, 1998Assignee: Polaroid CorporationInventors: James R. Boyack, Andrew K. Juenger

Patent number: 5449586Abstract: A novel method and apparatus is disclosed for electronically sensing a negative and a positive in a novel integral film structure of the instant development type using light of different wavelengths so as to produce reflected light from the negative and the positive which are indicative of the luminance characteristics and the chrominance characteristics of the image. The novel integral film structure has a filter which allows the negative to be scanned. Specifically, the filter transmits incident infrared radiation to which silver halide emulsion layers are sensitive and blocks the transmission of radiation in the range of wavelengths to which the silver halide emulsion layers are sensitive.Type: GrantFiled: November 8, 1994Date of Patent: September 12, 1995Assignee: Polaroid CorporationInventors: F. Richard Cottrell, Andrew K. Juenger, Hugh R. Mackenzie, William J. McCune, Jr., William T. Plummer

The novel integral film structure has a filter which allows the negative to be scanned. Specifically, the filter transmits incident radiation in the range of wavelengths other than a select range of wavelengths to which silver halide emulsion layers are sensitive and blocks the transmission of radiation in the range of wavelengths to which the silver halide emulsion layers are sensitive.Type: GrantFiled: July 15, 1992Date of Patent: April 18, 1995Assignee: Polaroid CorporationInventors: F.

Patent number: 5170261Abstract: Printing apparatus and method particularly suited to provide a hardcopy of an image which is produced by medical imaging equipment or the like. The method produces an area modulation hardcopy having a large number of gray levels per area modulation cell (pixel) and a strong density sensitivity preferably by pulse width modulating two different sized printing radiation beams.Type: GrantFiled: November 21, 1990Date of Patent: December 8, 1992Assignee: Polaroid CorporationInventors: Ellen B. Cargill, Fawwaz N. Habbal, Andrew K. Juenger
