A method for computing a depth map of a scene in a structured light imaging system including a time-of-flight (TOF) sensor and a projector is provided that includes capturing a plurality of high frequency phase-shifted structured light images of the scene using a camera in the structured light imaging system, generating, concurrently with the capturing of the plurality of high frequency phase-shifted structured light images, a time-of-flight (TOF) depth image of the scene using the TOF sensor, and computing the depth map from the plurality of high frequency phase-shifted structured light images wherein the TOF depth image is used for phase unwrapping.

Time-of-flight (TOF) assisted structured light imaging

Provided is a camera system to obtain high resolution imagery on multiple regions of interest even when the regions of interest are ate different focal depths and in different viewing directions. Embodiments include a high speed camera that operates by reflecting a beam of interest corresponding to a scene of interest into a high-speed passive sensor from a dynamic optical modulator. Embodiments described herein provide a foveating camera design that distributes resolution onto regions of interest by imaging reflections off a scanning micro-electromechanical system (MEMS) mirror. MEMS mirrors are used herein to modulate viewing direction. Embodiments include a camera capturing reflections off of a tiny, fast moving mirror.

Fast foveation camera and controlling algorithms

Methods and apparatuses for enlarging the optical scan angle of imaging probes are provided. The optical scan angle of endoscopic probes can be increased by employing the 'Snell's Window' effect. An endoscopic probe can include an endoscope shell, a device for capturing electromagnetic radiation, and a liquid or gel provided between the device for capturing electromagnetic radiation and the endoscope shell. The endoscope probe can further include a first mirror placed such that electromagnetic radiation entering through the endoscope shell can bounce off the first mirror and enter the device for capturing electromagnetic radiation. The first mirror can be a microelectromechanical systems (MEMS) mirror.

Endoscopic OCT probes with immersed MEMS mirrors

Provided are methods, apparatuses, and systems for tracking a pupil of an eye of a user with degraded iris authentication accuracy. In certain examples, an eye tracking device includes a camera adapted to capture an eye image of at least one eye of a user. The eye tracking device further includes an image processor adapted to defocus the eye image in order to generate a defocused eye image. The defocused eye image comprises reduced iris authentication accuracy. The eye tracking device further includes a tracking processor configured to detect a pupil in the defocused eye image and determine a gaze direction of the user based at least in part on one or more of the defocused eye image and the pupil.

Eye tracking apparatuses configured for degrading iris authentication

Embodiments are directed to an optical privatizing device (), system and methods of use. The device includes a removable frame () removably attachable to a sensor housing (A). A device includes a blurring lens () coupled to the removable frame () and configured to optically modify light passing to a depth sensor wherein the optical modified light has a privatizing blur level to neutralize a profile of an object sensed by the depth sensor within a working volume of the depth sensor to an unidentifiable state while maintaining a depth parameter sensed by the depth sensor.

Optical privatizing device, system and method of use

A method of controlling image focus in a digital imaging system is provided that includes receiving a depth-scene image pair generated by a depth-scene image sensor pair comprised in the digital imaging system, aligning the depth image with the scene image wherein each pixel in the scene image has a corresponding depth in the aligned depth image, detecting a user gesture associated with a focus effect, and blurring, responsive to the user gesture, at least a portion of the scene image according to the focus effect, wherein the blurring is based on depths in the depth image.

Controlling image focus in real-time using gestures and depth sensor data

A method of improving depth sensor data in real-time based on scene sensor data is provided that includes aligning depth images of depth-scene image pairs generated by a depth-scene image sensor pair with corresponding scene images wherein, for each depth-scene image pair, the depth image is warped such that locations of depths in the depth image are aligned with locations of corresponding pixels in the scene image, and improving at least some of the aligned depth images based on image data from one or more of the scene images.
