Wireless transfer system

In a transmission device used in a wireless video transmission system in which a medical image is transmitted and received by radio communication, a transmission unit is capable of performing radio communication with a plurality of receiving devices connected to a plurality of display apparatuses. A control unit acquires an identifier for identifying a receiving device connected to a selected single display apparatus when an instruction is received to select one display apparatus on which the medical image is to be displayed from among the display apparatuses, and controls the transmission unit such that the identifier will be used when the medical image is transmitted.

Wireless video transmission system and transmission device

In a processor of a wireless image transmission system that transmits, by radio communication, an image signal obtained by converting an image obtained by an endoscope apparatus, a communication state detection unit monitors a communication state of radio communication. An editing unit edits the image signal according to a mode in which the endoscope apparatus obtains an image when the deterioration of a communication state is detected by the communication state detection unit. A transmission unit transmits the image signal output from the editing unit to a receiver.

To provide an image pickup system having CCDsdriven at different frequencies respectively which can drive each CCDwith a predetermined frequency if a detachable camera head (or electronic endoscope)is used and also can process a signal processing clock of a video processing circuitwith one type of clock. A drive signal of the predetermined frequency supplied to the CCD is produced via a generating circuit CXOin the video processing circuit, a frequency dividing circuitand a timing generator (T.G.). A CCD signal outputted from the CCDis inputted to a line memoryin a floating circuit. As a writing clock (WCK) of the line memory, the one which is divided in the frequency dividing circuitto a frequency in accordance with the CCDto be used is used, and as a reading clock (RCK), the one of one type of frequency is used without regard to the CCDto be used. Hence, it is possible to perform the signal processing of a secondary circuitof the line memoryand following ones always with a common generating clock.

Image pickup system

A camera control unit for processing a signal output from an imaging device incorporated in an endoscope is provided with an analog video signal output terminal through which a video signal is output to a monitor, and a digital video signal output terminal to which a still image-specific or motion picture-specific expansion unit is coupled in a freely detachable manner. By handling a release switch, a still image or motion picture can be recorded digitally. Even when the recorded image data is edited or subjected to any other processing, deterioration of image quality can be prevented. An imaging system having these advantages can be realized on a small scale.

Endoscopic imaging system in which still image-specific or motion picture-specific expansion unit can be coupled to digital video output terminal in freely uncoupled manner

When an endoscopic imaging system is employed in, for example, the department of otorhinology, a color processing expansion substrate, a still image production expansion substrate, and a still image compression/recording substrate are stacked on an expansion connector formed on a main substrate and are thus connected to the main substrate. A data bus and an address bus extending from a control unit mounted on the main substrate are linked to the expansion substrates. A sync signal generator outputs various kinds of sync signals including a clock signal CLK, a horizontal sync signal HD, a vertical sync signal VD, a field identification signal FLD, and a composite sync signal CSYNC to the expansion substrates.

Image processing unit with expandable signal processing capability and endoscopic imaging systems

An imaging apparatus having an imaging device for imaging an object in cooperation with an endoscope is connected to a video processing unit for producing a standard video signal so that it can be disconnected freely. A signal delay occurs over a signal line linking the imaging device and the video processing unit. For this reason, a timing generator and a phase adjustment circuit are incorporated in the imaging apparatus. The timing generator generates driving signals used to drive the imaging device, and the phase adjustment circuit adjusts the phases of the driving signals so that an output signal of the imaging device will be input to the video processing unit according to predetermined timing. Even when the signal line has a different length from any other or the imaging device offers a different number of pixels from any other, the difference can be readily coped with owing to the imaging apparatus. This leads to alleviation of a load incurred by the video processing unit.

Endoscopic imaging system and endoscope system

In an endoscopic imaging system, a signal representing an object image produced by a scope and projected by a camera head is processed by a CCU and displayed as an endoscopic image on a TV monitor. The object image is stored as digital image data on a memory in the CCU, read as image data of a still image, and recorded on a PC card mounted in a PC card slot. The PC card slot is formed in the front panel or the like of the CCU. A lid member or the like functioning as an anti-liquid invasion member and shield can be located at an opening of the slot.

One expansion substrate or a plurality of expansion substrates that realize different facilities can be connected to a main substrate that realizes basic processing to be performed by a CCU. Based on an ID number produced by an ID generation unit mounted on a connected expansion substrate, a CPU incorporated in the CCU identifies the facility realized with the expansion substrate. A menu screen image presents item BOD Control under which the facilities are presented. When item BOD Control is designated, a BOD Control screen image that lists control items indicating the facilities realized with all the expansion substrates that are connected to the main substrate is displayed. When a concrete facility such as a P-in-P facility realized with an expansion substrate is selected or designated in the BOD Control screen image, a screen image concerning the designated P-in-P facility is displayed. Thus, the details of a facility that is realized with a connected expansion substrate can be set easily.
