CPC Class H04N

A method and apparatus for enhancing the signal to noise ratio performance of a depth camera system are described. In one embodiment, the method includes exposing a portion of a pixel array of a rolling camera sensor, and activating a portion of a rolling projector to generate a portion of a projection pattern during the exposure of the portion of the pixel array. The method may also include capturing image data for the generated portion of the projection pattern with the exposed portion of the pixel array of the rolling camera sensor. Furthermore, the method may include performing depth reconstruction based, at least in part, on the captured image data.

In a distance measuring device, a pixel G includes sub pixels Po and Pe in a row direction. Floating diffusion parts Fd1 to Fd4 detect charge quantities relating to reflected modulated light Lb in four terms which are delayed in start by every ¼ of a period of emitted modulated light La in order. A binning group Gv is configured by an array part that the two sub pixels Po and the two sub pixels Pe are adjacent to each other in a row direction.

A danger monitoring system is disclosed. A danger monitoring device comprises a microphone configured to continuously digitize environmental sound, a first memory, a first processor configured to determine whether a stored interval meets a threshold criteria for a dangerous event, and a first network interface configured to send a danger observation data to a server. The danger monitoring server comprises a second memory, a second processor configured to verify the dangerous event digitized by the danger monitoring device and determine an event location of the verified dangerous event, and a second network interface configured to send a danger alert. A danger mitigation device comprises a third network interface configured to receive the danger alert, a GPS receiver, a screen, a third memory comprising map data, and a third processor configured to render a map indicating at least a current location of the danger mitigation device, and the event location.
