Patent number: 11009715Abstract: Systems and methods for fitting a wearable heads-up display (WHUD) to a subject are described. Imaging data representative of at least a portion of the subject's head with one or more gaze positions of the eyes is obtained from a plurality of cameras. One or more models representative of the subject's head are generated and a set of features is recognized in the one or more models. One or more models of the WHUD are also obtained based on WHUD data stored in memory. One or more simulations are performed positioning one or more WHUD models in proximity to at least one subject model based at least in part on the set of features recognized in the subject model. A fit of a WHUD to the subject is evaluated based at least in part on a determination regarding whether the simulation satisfies one or more of a set of criteria.Type: GrantFiled: September 11, 2019Date of Patent: May 18, 2021Assignee: Google LLCInventors: Samuel Jewell Lochner, Sui Tong Tang, Kevin R.

Patent number: 10547793Abstract: A camera unit and method of control are described. The camera unit has a camera flash sub-unit configurable to emit flash light having an adjustable characteristic. A camera sensor sub-unit generates raw color data when exposed to light for processing into a digital image. The camera unit also includes a camera controller for coordinating operation of the camera flash sub-unit and the camera sensor sub-unit. The camera controller monitors one or more ambient light characteristics in a vicinity of the camera unit. Prior to receiving a command instructing the camera unit to generate the digital image, the camera controller repeatedly configures the camera flash sub-unit based on the monitored ambient light characteristics to adjust the characteristics of the emitted flash light. Once the camera controller receives the command, the camera sensor sub-unit is instructed to expose an image sensor using the pre-adjusted camera flash light to increase illumination.Type: GrantFiled: May 4, 2017Date of Patent: January 28, 2020Assignee: BlackBerry LimitedInventors: Qian Wang, Yun Seok Choi, Graham Charles Townsend, Sui Tong Tang

Publication number: 20180103193Abstract: Image capture systems, devices, and methods that automatically focus on objects in the user's field of view based on where the user is looking/gazing are described. The image capture system includes an eye tracker subsystem in communication with an autofocus camera to facilitate effortless and precise focusing of the autofocus camera on objects of interest to the user. The autofocus camera automatically focuses on what the user is looking at based on gaze direction determined by the eye tracker subsystem and one or more focus property(ies) of the object, such as its physical distance or light characteristics such as contrast and/or phase. The image capture system is particularly well-suited for use in a wearable heads-up display to capture focused images of objects in the user's field of view with minimal intervention from the user.Type: ApplicationFiled: December 12, 2017Publication date: April 12, 2018Inventor: Sui Tong Tang

Patent number: 8717464Abstract: A camera unit generates a processed digital image by augmenting color image data with infrared image data according to the level of ambient light exposure. The camera has an ambient light sensor that detects the level of ambient light in the camera unit and an image sensor that provides image data. One or more quantum dot layers may be included in the image sensor. A camera controller adapts the camera unit for operation in different modes that are selectable based on the levels of detected ambient light. The image data is processed into a digital image, according to the selected mode of operation for the camera unit, using color image data only when the level of ambient light is high, but augmenting the color image data with infrared image data when the level of ambient light is low to increase the color luminance of the final processed digital image.Type: GrantFiled: February 6, 2012Date of Patent: May 6, 2014Assignee: BlackBerry LimitedInventor: Sui Tong Tang

Patent number: 8687882Abstract: An apparatus, and an associated method, facilitates selection of white balancing to adjust the color cast of a captured image. A quantum dot element is positioned to receive incident light associated with a scene forming an image that is to be captured. Incident light upon the quantum dot element causes photonic emissions that are detected and converted into electrical form. The electrical representations of the photonic images are used to measure or determine a color ratio. The value of the color ratio is utilized to select white balancing of a captured image, captured either prior to, concurrent with, or subsequent to, the color-ratio determination.Type: GrantFiled: December 23, 2011Date of Patent: April 1, 2014Assignee: BlackBerry LimitedInventor: Sui Tong Tang
