Abstract: Time-of-flight cameras may be synchronized where the fields of view of the time-of-flight cameras overlap. The time-of-flight cameras may be programmed within intervals of time for illuminating their respective fields of view that do not conflict with one another. When a first time-of-flight camera illuminates a first field of view that overlaps with a second field of view of a second time-of-flight camera, and the second time-of-flight camera detects reflected light from the illumination, the second time-of-flight camera may determine a time to illuminate the second field of view based on the reflected light. A time-of-flight camera may include an image sensor modified to include one or more modulated light sensors among an array of photoreceptors. A modulation frequency or illumination interval may be selected for the time-of-flight camera based on modulation frequencies or illumination intervals of other cameras, as determined based on data captured by the modulated light sensors.

Abstract: An image pickup apparatus, image processing apparatus and corresponding program and method are disclosed. In one example, a second captured image acquired from another apparatus is aligned with a first captured image. Image stabilization is carried out in response to a positional relation between the captured images. For example, when overlapping between the captured images is equal to or smaller than an image stabilization limitation threshold value, the image stabilization is stopped or a correction range is limited for at least one of the captured images. When the amount of overlapping is larger than the image stabilization limitation threshold value, the image stabilization for both of the captured images is carried out without limitation. The captured images are aligned with each other by using the captured image with limited image stabilization, or both captured images where stabilization is carried out without limitation, thereby producing a panoramic image.

Abstract: A quick release assembly for use in mounting a display system to a fixture. The system includes an attachment assembly on a back side of the display system that receives pins from a mounting bracket into openings of lock modules that include a latch that holds at least one pin in place. The latch is held in the lock position by spring bias. An actuator wire made of a shape memory alloy contracts when an electrical current is applied. The contraction of the wire overcomes the spring bias to move the latch from the lock position to an unlocked position to allow the display system to be removed from the pin.
