Patent number: 9851245Abstract: Embodiments related to accumulating charge during multiple exposure periods in a time-of-flight depth camera are disclosed. For example, one embodiment provides a method including accumulating a first charge on a photodetector during a first exposure period for a first light pulse, transferring the first charge to a charge storage mechanism, accumulating a second charge during a second exposure period for the first light pulse, and transferring the second charge to the charge storage mechanism. The method further includes accumulating an additional first charge during a first exposure period for a second light pulse, adding the additional first charge to the first charge to form an updated first charge, accumulating an additional second charge on the photodetector for a second exposure period for the second light pulse, and adding the additional second charge to the second charge to form an updated second charge.Type: GrantFiled: November 6, 2012Date of Patent: December 26, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: David Cohen, Shlomo Felzeshtein, Eli Larry

Patent number: 8717469Abstract: An embodiment of the invention provides a camera comprising a photosurface that is electronically turned on and off to respectively initiate and terminate an exposure period of the camera at a frequency sufficiently high so that the camera can be used to determine distances to a scene that it images without use of an external fast shutter. In an embodiment, the photosurface comprises pixels formed on a substrate and the photosurface is turned on and turned off by controlling voltage to the substrate. In an embodiment, the substrate pixels comprise light sensitive pixels, also referred to as “photopixels”, in which light incident on the photosurface generates photocharge, and storage pixels that are insensitive to light that generates photocharge in the photopixels. In an embodiment, the photosurface is controlled so that the storage pixels accumulate and store photocharge substantially upon its generation during an exposure period of the photosurface.Type: GrantFiled: February 3, 2010Date of Patent: May 6, 2014Assignee: Microsoft CorporationInventors: Shlomo Felzenshtein, Giora Yahav, Eli Larry

Publication number: 20120154535Abstract: A photosensitive surface of an image sensor, hereafter a photosurface, of a gated 3D camera is controlled to acquire both gated and ungated light in the same frame on different areas of its surface. One image capture area of the photosurface acquires gated light during a gated period while another image capture area is OFF for image data capture purposes. During an ungated period, the other image capture area of the same photosurface captures ungated light as image data. Typically, the gated and ungated periods are interleaved during the same frame period.Type: ApplicationFiled: December 15, 2010Publication date: June 21, 2012Applicant: MICROSOFT CORPORATIONInventors: Giora Yahav, Shlomo Felzenshtein, Eli Larry
