Abstract: An imaging system includes first camera; second camera, second field of view of second camera being wider than first field of view of first camera, wherein first field of view overlaps with portion of second field of view; and processor(s) configured to: capture first images and second images, wherein overlapping image segment and non-overlapping image segment of second image correspond to said portion and remaining portion of second field of view; determine blurred region(s) (B1, B2) of first image; and generate output image in manner that: inner image segment of output image is generated from: region(s) of overlapping image segment that corresponds to blurred region(s) of first image, and remaining region of first image that is not blurred, and peripheral image segment of output image is generated from non-overlapping image segment.

Abstract: A tracking system includes light sources arranged spatially around user-interaction controller(s) of head-mounted device; a controller-pose-tracking means is arranged in the user-interaction controller(s); an HMD-pose-tracking means and camera(s) arranged on a portion of HMD that faces a real-world environment. Processor(s) are configured to estimate a relative pose of the controller(s) with respect to the HMD, determine current value and/or pulse width modulation (PWM) value to be employed for controlling brightness of light source(s) from amongst the light sources, generate control signal for setting current value and/or PWM value for light source(s), and send a control signal to controller(s). The process image(s) captured by camera(s) identify blob(s) representing light source(s) and correct estimated relative pose, based on at least one of: position, orientation, brightness, size, shape, of the blob(s).
