Publication number: 20170129402Abstract: A camera suitable for use on an automated vehicle includes an imager-device, a lens-module, and an array of light-guides. The imager-device is operable to determine an image and includes a plurality of light-detecting pixels. Each pixel is overlaid with a micro-lens. The lens-module directs light from a field-of-view of the camera toward the imager-device. The array of light-guides is interposed between the lens-module and the imager-device, and is arranged so each instance of light-guide is aligned with a corresponding instance of micro-lens. Each light-guide is defined by a lens-end and an imager-end. The lens-end of each of the light-guides cooperates to define a planar-surface of the array, and imager-end of the light-guide is characterized by an angle selected to direct light within the light-guide toward the corresponding instance of the micro-lens. The angle is determined based on a chief-ray-angle (CRA) of light from the lens-module impinging on the lens-end.Type: ApplicationFiled: November 5, 2015Publication date: May 11, 2017Inventors: YEW KWANG LOW, KOK WEE YEO, CHEE KENG YEO

Each visible-light pixel is characterized by a first-area. The device also includes an arrangement of infrared pixels interleaved with the visible-light pixels. Each infrared pixel is characterized by a second-area greater than the first-area. The visible-light pixels are alternatively characterized by a first-resolution, so the infrared pixels are characterized by a second-resolution less than the first-resolution. The device also defines a plurality of pixel-cells. Each pixel-cell includes a visible-light pixel and a portion of an infrared pixel that is part of an adjacent pixel-cell.Type: ApplicationFiled: October 28, 2015Publication date: May 4, 2017Inventors: YEW KWANG LOW, KOK WEE YEO, CHEE KENG YEO

Patent number: 9042717Abstract: An image system configured to record a scanned image of an area. The system includes a single two-dimensional (2D) imager and a rotatable mirror. The 2D imager is formed of a two-dimensional (2D) array of light detectors. The 2D imager is operable in a line-scan mode effective to individually sequence an activated line of light detectors at a time. The rotatable mirror is configured to rotate about an axis parallel to a plane defined by the rotatable mirror. The rotation is effective to vary an angle of the rotatable mirror to pan a projected image of the area across the 2D imager. The angle of the rotatable mirror and the activated line of the 2D imager are synchronized such that the scanned image recorded by the 2D imager is inverted with respect to the projected image.Type: GrantFiled: July 31, 2013Date of Patent: May 26, 2015Assignee: Delphi Technologies, Inc.Inventors: Yew Kwang Low, Kok Wee Yeo, Chee Keng Yeo, Ronald M. Taylor, Ward K. Everly, William Garrison Shogren

Publication number: 20140355974Abstract: A multi-view image system that includes a single camera configured to capture an image, and a transreflective device. The transreflective device is operable to a transparent-state where light passes through the transreflective device to provide the camera a first image of an area from a first perspective. The transreflective device is also operable to a reflective-state where light is reflected by the transreflective device to provide the camera a second image of the area from a second perspective distinct from the first perspective. The system may also include a minor arrangement that cooperates with the transreflective device to provide the camera the first image when the transreflective device is in the transparent-state, and the second image when the transreflective device in in the reflective-state.Type: ApplicationFiled: June 4, 2013Publication date: December 4, 2014Inventors: YEW KWANG LOW, KOK WEE YEO, CHEE KENG YEO, RONALD M.
