An electronic camera system includes a programmable transmission capability for selectively transmitting electronic image data to a plurality of remote base units. In one embodiment, a camera module is detachably coupled to a portable computer including a display screen and a data entry device. The electronic image data generated by the camera module is supplied to the portable computer for display on the display screen. The data entry device is used by an operator to select which of the plurality of base units are to receive the digital image data. The digital image data is supplied by the portable computer to a radio-frequency transmitter module for transmission to the selected base units. The radio-frequency transmitter module is formed either integral with the portable computer or, like the camera module, is detachably coupled to the portable computer. In a further embodiment, a combined telephone/camera unit is provided that includes a camera module for generating electronic image data representative of a scene to be imaged, a memory unit for storing the electronic image data generated by the camera module, a display screen for displaying the electronic image data stored in the memory unit, a mechanism for selecting which of the plurality of base units is to receive the digital image data, and a cellular transceiver for transmitting the digital image data to the base units selected by the selection mechanism.

An integrated Internet camera includes, as embedded components contained within the camera body and controlled by a microcontroller, at least a network interface device for connecting to the Internet, a transport control device for packetizing according to Internet protocols, a file transfer device for communicating with a destination user directory on the Internet, and a transmission initiating device for initiating the connection and transfer operations of the file transfer device and transport control device. The network interface device may be a modem, network adapter, or adapter for connection to the Internet. Upon capturing the digital image, the camera initiates a connection to the Internet, connects to the destination user directory, and uploads the digital images. Thereafter, the digital images are available to authorized (or any) user having access to the Internet.

This invention provides an image capturing lens assembly in order from an object side to an image side comprising: a first lens group has only one first lens element with a positive refractive power, and a second lens group in order from the object side to the image side comprising: a second lens element with a negative refractive power, a third lens element, a fourth lens element and a fifth lens element; while a distance between an imaged object and the image capturing lens assembly changes from far to near, focusing is performed by moving the first lens group along the optical axis and a distance between the first lens group and an image plane changes from near to far. By such arrangement and focusing adjustment method, good image quality is achieved and less power is consumed.

An apparatus, system and method for providing a photographic image of a target region within an intravascular environment. The apparatus has a plurality of different embodiments, each of which reduces the ambient 'noise' detected along with the light reflected from the target region in order to increase the signal/noise ratio, thereby to enhance the quality of the image produced.

Apparatus, method and system for intravascular photographic imaging

PROBLEM TO BE SOLVED: To provide an electronic image pickup device in which a lens system can easily be exchanged to a different image pickup element and can easily deal with model change is good without the fear of wasting an expensive beam splitter and an image pickup element when the image pickup lens system breaks down. SOLUTION: The beam splitter 27 and the image pickup element 33 are incorporated in an optical finder unit with optical parts for optical finder. The optical finder unit is constituted of a finder case storing the optical parts for finder and a holding member holding the beam splitter 27 and the image pickup element 33. The image pickup face of the image pickup element 33 is slantingly arranged against the incident luminous flux of the beam splitter 27. Incident luminous flux to the image pickup element 33 is reflected twice in the beam splitter and the incident luminous flux of a finder optical system 35 to the finder passes through the beam splitter 27 without reflection.
