A system includes at least two capture devices, each switchable from a respective idle mode to a respective recording mode upon receipt of a trigger signal from a trigger via a network. A controller saves data packets generated by the capture devices during the respective idle modes to a short-term memory, and saves data packets generated during the respective recording modes to a long-term memory such that the data packets form respective saved data streams. The synchronizer sends a sync signal to the capture devices via the network. The compensator determines respective delay periods between sending of the sync signal by the synchronizer and receipt of the sync signal by each of the capture devices, and transfers from the short-term memory to the long-term memory any data packets generated during the respective delay period.

Provided is an image sensor configured to function as a synchronous master that controls synchronous imaging performed by a plurality of image sensors. In a case where a stop request is acquired, the image sensor stops imaging operation on the basis of the stop request, and does not transmit, to a different image sensor functioning as a synchronous slave that performs imaging under control by the synchronous master, a synchronous slave synchronous signal for controlling imaging timing of an image sensor functioning as the synchronous slave on the basis of the stop request.

A head-mounted display (HMD) is configured to capture images and/or video of a local area. The HMD includes an imaging assembly and a controller. The imaging assembly includes a plurality of cameras positioned at different locations on the HMD and oriented to capture images of different portions of a local area surrounding the HMD. The controller generates imaging instructions for each camera using image information. The imaging instructions cause respective midpoints of exposure times for each camera to occur at a same time value for each of the captured images. The cameras capture images of the local area in accordance with the imaging instructions. The controller determines a location of the HMD in the local area using the captured images and updates a model that represents a mapping function of the depth and exposure settings of the local area.

The present technology relates to an imaging device, an imaging control method, and a program that enable a plurality of imaging devices to be synchronized with each other, without connection by a cable. The imaging device includes a rolling shutter type imaging element; an analysis unit analyzing a light reception distribution to be a distribution of a light reception amount of a pixel column direction of the imaging element for pulsed light of a predetermined frequency; and an imaging control unit adjusting an imaging timing of the imaging element, on the basis of the light reception distribution. The present technology can be applied to an imaging device including a rolling shutter type CMOS image sensor, for example.

Multiple image capture devices may individually generate time information and capture images. Individual image captures devices may receive time information of other image capture device(s). Individual image capture devices may transmit its time information to other image capture device(s) independent of reception of the time information of other image capture device(s). Individual image capture devices may generate time synchronization information for the captured images based on its time information and the received time information of other image capture device(s). Images captured by different image capture devices may be time-synchronized based on at least one of generated time-synchronization information.

An initialization method for initializing a transfer of a recording image data stream from an image sensor of an image recording apparatus to a display unit, wherein initially a display image data stream in the form of a test image is transferred from an image processing apparatus to the display unit and a recording image data stream is transferred from an image recording apparatus to the image processing apparatus. A changeover of a reproduction on the display unit to the recording image data stream is preceded by a correction value being calculated for a phase shift between the display image data stream and the recording image data stream and being transferred to the image recording apparatus, and the recording image data stream is phase-shifted by the correction value. Subsequently the display image data stream is changed over to the recording image data stream (21) and the image recorded by the image sensor or the sequence of images is reproduced with the display unit.

The present invention relates to a method for generating control signals for an image capture device, the method being performed in a communication device comprising a first slave time generator and a second slave time generator, the communication device being connected to a first remote time server and a second remote time server, the method comprising: synchronizing the first slave time generator with the first remote time server; synchronizing the second slave time generator with the second remote time server; generating a first control signal based on the first clock, and sending the first control signal to the image capture device; and upon detecting a loss of synchronization between the first slave time generator and the first remote time server, generating a second control signal based on the second clock, and sending the second control signal to the image capture device.

A display system includes a controller and an image display panel. The controller includes a signal transmitter configured to output at least a vertical synchronization signal to a plurality of image-capturing apparatuses; and a synthesizer configured to provide synthesized image signals in units of lines obtained by synthesizing, in units of lines, image signals in units of lines output from the respective image-capturing apparatuses at a timing corresponding to a horizontal synchronization signal formed in a predetermined cycle based on an output timing of the vertical synchronization signal. The image display panel is configured to display sequentially, in units of lines, the synthesized image signals in units of lines.

Systems and methods of multiplexing information from a plurality of monochrome sensors/cameras is provided. The systems and methods provided can be useful to achieve pixel-level time synchronization between information acquired by different monochrome sensors/cameras that are configured to view a scene from different viewing directions.

An apparatus and method are provided for viewing panoramic images and videos through the selection of a particular viewing angle and window (zoom) within that panorama while allowing the viewer to simultaneously implement temporal transport control, allowing the video to be in a state of pause, play, fast forward, fast rewind, slow forward, slow rewind, or frame-by-frame. This capability may be used on video that is residing in memory on the viewer's viewing system, in a hard disk local to the viewer or in a shared location, or on a live buffered feed of video. A second capability of this apparatus and method relates to the use of a plurality of panoramic video or images from multiple synchronized cameras. In those cases, all panoramic video feeds are synchronized so that as a viewer pauses, rewinds, forwards a video in one panorama, all panoramas are time synchronized and go through the same states as the panorama being viewed. When the user selects a different panorama for viewing from a different camera, this panorama comes up in the same state as the panorama previously being viewed.
