A portable video and imaging system includes a camera for capturing video of an event, and a video recording device for recording the captured video of the event. The camera is housed in a first housing, the recording device is housed in a second housing, and the first and second housings are physically separate. Various embodiments provide for the system to be mounted to a user's body, an article of clothing, such as a shirt or a hat, to a vehicle, or to an ancillary component carried by the user, such as a firearm.

A lens unit L100 is removably mounted on an image pickup apparatus generating control information used for a vibration control that vibrates a correction lens L105 and moves a vibration center of the correction lens L105, includes an image pickup optical system including a magnification varying lens L102 and the correction lens L105, a storage unit storing first information indicating a relation between positions of the magnification varying lens L102 and the correction lens L105, and a lens controller performing a predetermined control in which the correction lens L105 moves in accordance with the movement of the magnification varying lens L102, and the lens controller sends information relating to the magnification varying operation to the image pickup apparatus, and overlaps the vibration control of the correction lens L105 based on the control information in accordance with the information relating to the magnification varying operation with the predetermined control.

A camera system, a camera body, and a communication method capable of satisfactorily acquiring lens information necessary for image processing or the like for a frame of a video from an interchangeable lens are provided. Three-wire serial communication is performed in which a request signal is transmitted to the interchangeable lens in synchronization with a synchronization signal (VSYNC) of an imaging element in a video recording mode, and a response signal is received from the interchangeable lens. In a communication mode in the video recording mode, the number of transmissions of a first request signal relating to acquisition of lens information such as a focus position, a diaphragm value, and a zoom position is limited. Accordingly, communication other than communication relating to acquisition of lens information can be performed in a period of one frame.

This application describes techniques for controlling an apparatus that includes a camera both locally and remotely. The camera apparatuses described herein may include obfuscation components that function to selectively obfuscate a view of the camera at the request of a user. For instance, one particular camera apparatus may include a lens cap and an actuator to move the lens cap from a position in which the lens cap at least partially obfuscates the view of the camera to a position in which the lens cap does not (and vice versa). The camera apparatus may include a physical control to allow a user to locally request to open or close the lens cap, and may also include a network interface to communicate with a user device, thus allowing a user to remotely request to open or close the lens cap.

The present invention is capable of spontaneously providing a status notification to an external device in an appropriate manner. To achieve this aim, the external device, upon establishing communication with a communication apparatus, makes a status notification request to the communication apparatus, the status notification request being a request for a response that, when a change occurs in an internal status of the communication apparatus, indicates the change. Also, upon making a request to serve as a remote camera to the communication apparatus via a user interface, the external device makes a status notification request to the communication apparatus, regardless of whether or not a response has been made to the first request.

To display an image and the back side image in an overlapped state on a screen, with good visibility and see-through capability. The screen scanned with an image light from the projector has an optical layer and a plurality of control electrodes which are arranged side by side along the optical layer. The synchronous controller applies a voltage to the plurality of control electrodes, and, in a scanning period T of the image light, switches the optical state of the screen by the unit of the segmented region, between the visual state and the nonvisual state. The synchronous controller, in the period T, switches the optical state of a plurality of segmented regions 22 in synchronous with the scanning period of the image light, maintains the optical state of a projected region of the screen in the visual state by a voltage with two or more amplitudes.

An imaging system includes a flash device that can automatically drive a movable unit provided with a light emitting unit to change an irradiating direction of the light emitting unit, and an imaging device. The imaging system includes a first distance measuring unit that measures a distance to an object, a correcting unit that corrects first distance information obtained by the first distance measuring unit performing measurement, and a calculating unit that calculates the irradiating direction of the light emitting unit based on the corrected first distance information, wherein the correcting unit corrects the first distance information in a direction in which the irradiating direction calculated by the calculating unit separates away from the object.

In an example implementation according to aspects of the present disclosure, a method may include capturing data entered on a touch sensitive mat or on an object physically disposed on the touch sensitive mat. The method further includes extracting the data from the captured image, and developing contextual information from the data extracted from the captured image. The method further includes projecting the contextual information onto the touch sensitive mat or onto the object.

The accessory apparatus includes an accessory communicator providing a notification channel, a first data communication channel and a second data communication channel. The accessory controller transmits, in response to receiving a transmission request from an image-capturing apparatus through the notification channel, accessory data to the image-capturing apparatus through the first data communication channel and receives camera data transmitted from the image-capturing apparatus through the second data communication channel. The accessory controller has a function of detecting a camera communication error in the camera data and is configured to, when detecting the camera communication error, transmit accessory error information to the image-capturing apparatus and erase the accessory data stored in an accessory data buffer.

The present disclosure relates to a computer implemented method and system for coordinating taking of a picture using a camera and initiation of a flash pulse of at least one flash device. The method is adapted for a system including a first device and at least one remote device. The method comprises the steps of obtaining a time base for a processor element of the first device, estimating a time base for a processor element of each at least one remote device in relation to the time base of the processor element of the first device, scheduling a timing for initiation of the flash pulse of the respective at least one flash device and/or a timing for taking a picture using the camera in the time base of the first device so that the coordination with the timing for taking the picture is obtained, and obtaining at the respective remote device of the system the scheduled timing of initiation of the remote device in the time base of that device.
