An integrated video/data information system for use on-board a commercial vehicle comprises a digital integrated data bus for conveying among bus compatible camera and display modules coupled to the bus video and data information in a digital format based on a predetermined bus protocol. Each camera module is operative to transmit, upon command, over the bus the image data in a digital format compatible with the predetermined bus protocol. Each display module is operative to receive from the bus, upon command, image data originating from a selected camera module, and to display the image data on a display monitor thereof. The system includes a bus master module coupled to the integrated data bus for transmitting commands over the bus to the camera and display modules. Such commands comprise a first command for directing a selected camera module to transmit image data thereof over the bus, and a second command for directing a selected display module to receive image data corresponding to the selected camera module from the bus and to display the received image data on the display monitor thereof. The first and second commands may be transmitted based on the operational status of the vehicle.

Systems and methods for receiving infrared data with a camera designed to detect images based on visible light are provided. A system can include a camera and image processing circuitry electrically coupled to the camera. The image processing circuitry can determine whether each image detected by the camera includes an infrared signal with encoded data. If the image processing circuitry determines that an image includes an infrared signal with encoded data, the circuitry may route at least a portion of the image (e.g., the infrared signal) to circuitry operative to decode the encoded data. If the image processing circuitry determines that an image does not include an infrared signal with encoded data, the circuitry may route the image to a display or storage. Images routed to the display or storage can then be used as individual pictures or frames in a video because those images do not include any effects of infrared light communications.

A motion-capture system is provided. The motion-capture system includes a host computing system and a plurality of motion-capture cameras that are operatively coupled with the host computing system. Each of the motion-capture cameras is disposed in a different location and orientation relative to a motion-capture space and includes a marker-tracking optical filter to provide a marker-tracking mode and thereby relatively enhance light from markers on a moving body in the motion-capture space. One or more of the motion-capture cameras is remotely controllable to selectively interchange the marker-tracking optical filter with a scene-view optical component, so as to selectively transition the motion-capture camera between the marker-tracking mode and a scene mode, in which light from the markers is less enhanced than in the marker-tracking mode.

An inkjet nozzle includes a first wafer having active drive circuitry together with an ink jet print nozzle formed therein; a second wafer having an ink channel formed therein; and a paddle layer sandwiched between the first and second wafers in a chamber complementarily defined by the wafers. The paddle layer is in signal communication with the active drive circuitry so that ink supplied via the ink channel is ejected via the print nozzle upon actuation of the paddle layer by the circuitry. The first wafer includes a silicon wafer upon which is fabricated an epitaxial boron doped layer, an epitaxial silicon layer, drive transistors and distribution circuitry forming a CMOS logic and drive transistor level, and a silicon nitride layer.

An adapter includes: a first mount section that is detachably attached to a camera body; a second mount section that is provided separately from the first mount section and is detachably attached to an interchangeable lens; and an adapter control section that is capable of communicating between the camera body mounted on the first mount section and the interchangeable lens mounted on the second mount section. The adapter control section provides body transmission lens information for transmission to the camera body, on the basis of lens information requested from the camera body and lens information received from the interchangeable lens, through mutually different methods according to types of the lens information.

A digital camera comprises an interchangeable lens unit and a camera body. The interchangeable lens unit is provided to form an optical image of a subject. A flash memory is configured to hold a correction coefficient table used to electrically correct distortion produced by the optical system. The camera body has a CCD image sensor, a correction coefficient acquisition part, an operation part, and a correction processor. The correction coefficient acquisition part is configured to acquire the correction coefficient table held in the flash memory. The operation part is configured to produce correction data by performing an interpolation operation or an extrapolation operation on the information obtained from the correction coefficient table. The correction processor is configured to correct distortion in the image data on the basis of information produced by the operation part.

In the case of printing while a digital camera is directly connected to a printer, it has been impossible to determine to what extent image blurring affects a print image. In an imaging device, a detection section ( 17 A) detects blurring. An image blurring compensation section ( 15 A) compensates image blurring. A compensation amount detection section ( 16 ) detects an image blurring compensation amount. A calculation section ( 19 A) calculates a residual blurring amount by subtracting the image blurring compensation amount from an image blurring amount. An image recording section ( 12 ) records an image signal, as a shot image, together with the residual blurring amount. A print size specification section ( 91 ) specifies a print size of the shot image and stores a tolerance (β) of the residual blurring amount with respect to the print size. And, a determination section ( 80 ) determines whether or not the residual blurring amount is equal to or greater than the tolerance with respect to a predetermined print size, and issues a warning to a photographer or the like in the case where the residual blurring amount is greater than the tolerance.

A lens position calculator is provided that determines a phase of a driving signal as a reference position of an imaging lens when an output value of a position detection sensor reaches a threshold value. The lens position calculator determines a position obtained by performing addition or subtraction on the reference position read out from a reference position storage as a judgment position, detects an output value of the position detection sensor at a timing in synchronization with the driving signal that drives a driver and at the judgment position, and judges whether the output value of the position detection sensor at the judgment position reaches the threshold value or not, so as to determine the reference position again.

A camera system that can maintain a good focus state regardless of the speed of zooming during variable proportion zooming is provided. The camera system has a control portion that, based on information on the speed of the change in the focal length, determines whether to control a focus lens drive portion in either a first control mode or a second control mode. If it determines that control is to be performed in the first control mode, then the control portion controls the focus lens drive portion so that it drives a focus lens in the direction that brings a predetermined captured object into focus based on estimated values for auto focusing that have been calculated from the image data at various positions by controlling the focus lens drive portion so that the captured object distance is moved forward and backward in the optical axis direction. If the control portion determines that control is to be performed in the second control mode, then the control portion controls the focus lens drive portion based on a tracking table.

A camera body (3) has a cross-shaped operation key (27) and a body microcomputer (10). The body microcomputer (10) can obtain lens information on an interchangeable lens unit (2) from the lens unit (2). The body microcomputer (10) determines, based on the lens information, whether the interchangeable lens unit (2) is compatible with an electric zoom operation. Further, based on the result of the determination, the body microcomputer (10) enables zoom operation by the cross-shaped operation key (27).
