Abstract: an apparatus configured to perform focus tracking on an object within a detection area to detect a defocus amount within an imaging angle of view includes a memory storing instructions, and a processor configured to execute the instructions to perform focus tracking determination to determine whether or not the focus tracking is to be performed using information about the defocus amount, and acquire information about a shield against the object from image data generated by imaging. the processor is configured to perform the focus tracking determination using information about the shield acquired in the detection area.

IPC Code(s): H04N25/68, H04N25/77
Abstract: an imaging device includes a photoelectric device in which a plurality of pixels containing a photoelectric element including an avalanche photodiode are arranged in a two-dimensional array, and a processor that processes output signals of the plurality of pixels. the plurality of pixels includes a first pixel unit having imaging pixels, and a second pixel unit having at least one set of pixels including an aperture pixel and light shielded pixels that surround at least a part of the aperture pixel, and the processor uses output signals of the aperture pixel and the light shielded pixels of the set of the pixels to generate a correction pattern for correcting output signals of the imaging pixels, the correction pattern corresponding to an output pattern of the set of the aperture pixel and the light shielded pixels.

IPC Code(s): H04N25/704, G02B7/04, H04N25/78
Abstract: an apparatus is provided with a sensor including a plurality of pixels that are arrayed two-dimensionally, at least a part of the plurality of pixels being a phase-difference detection pixel that include a first conversion unit and a second conversion unit for performing phase-difference af. a driving mechanism changes an angle of an image plane of the sensor relative to a main plane of an optical system. a readout unit reads out signals obtained in the first conversion unit and the second conversion unit in an order corresponding to the angle.

IPC Code(s): H04W74/08, H04W72/566
Abstract: in 802.11ax networks with access points, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access points. to make more effective the usage of the network, the access point may design the trigger frame to force the nodes to send some categories of data. resource units may be defined in trigger frames to be dedicated to small packets or to some access category data. adjusting the time length of the resource units helps restricting the type of data that can be conveyed by the resource units. also, using various frequency widths for resource units in the same trigger frame helps reducing padding in the resource units when various traffic types coexist.
