A reduced area imaging device is provided for use in medical or dental instruments
such as an endoscope. In a first embodiment of the endoscope, connections between
imaging device elements and between a video display is achieved by hard-wired connections.
In a second embodiment of the endoscope, wireless transmission is used for communications
between imaging device components, and/or for transferring video ready signals
to a video display. In one configuration of the imaging device, the image sensor
is placed remote from the remaining circuitry. In another configuration, all of
the circuitry to include the image sensor is placed in a stacked fashion at the
same location. The entire imaging device can be placed at the distal tip of an
endoscope. Alternatively, the image sensor can be placed remote from the remaining
circuitry according to the first configuration, and control box is used which communicates
with the image sensor and is placed remotely from the endoscope. Further alternatively,
the imaging device can be incorporated in the housing of a standard medical camera
which is adapted for use with traditional rod lens endoscopes. In any of the configurations
or arrangements, the image sensor may be placed alone on a first circuit board,
or timing and control circuits may be included on the first circuit board containing
the image sensor. The timing and control circuits and one or more video processing
boards can be placed adjacent the image sensor in a tubular portion of the endoscope,
in other areas within the endoscope, in the control box, or in combinations of
these location.
