摘要： The present invention is an imaging element assembly unit in which it can easily be promoted to make the diameter of the tip portion of an endoscope thinner by changing the configuration of a circuit board in relation to an image element. In this assembly unit, an imaging element body formed while holding a lead portion between an electrode of a CCD and a cover glass is produced, for example, on the TAB system, and this imaging element body is connected to a circuit board having a storing groove. Then, the width in the electrode arranging direction of this circuit board is formed shorter than the width in the electrode arranging direction of the CCD, and at a position where both ends of this circuit board retreat from both ends of the CCD, these are connected by a lead portion. By doing so, the diameter of the tip portion can be made thinner since the sides of both ends of the circuit board arranged on the side of the inside peripheral surface of a tip portion holding barrel retreat inside.

摘要： This endoscope apparatus utilizes a phenomenon called “curvature of field” of a lens to satisfactorily bring a shape, into focus, of an object to be observed such as unevenness especially during enlargement in accordance with a shape of unevenness or the like of the object. For example, there is provided an objective lens group having two movable lenses, and variable-power is performed and field curvature characteristics are changed by moving these movable lenses. This change in the field curvature characteristics is performed by operating an image surface curving switch and driving the movable lenses through the use of an actuator or the like. Also, information on differences in height on the image central part to the peripheral part is operated from the amount of field curvature changed by the objective lens group to display the information on differences in height on the monitor. Further, the image information on the divided areas are compared, and when the entire image is in focus, a static image is formed and the information on differences in height is displayed.

摘要： The present invention provides an electronic endoscope apparatus which prevents a picked up image from being blurred utilizing an optical magnification change mechanism. A viewing distance is changed by moving a movable lens with an actuator, magnification changing location of the movable lens is detected with an encoder and a shutter speed for a CCD which is shorter than an exposure time while the optical magnification changing mechanism is not operating is set with a CPU dependently on the magnification changing location. It is possible to prevent an image from being blurred, for example, by storing various patterns which provide higher electronic shutter speeds as an image magnification ratio is enhanced in a ROM and controlling an electronic shutter speed with these patterns. Furthermore, a variable width of a stop is limited to a predetermined width as the electronic shutter speed is enhanced and a gain of a video signal is enhanced with an AGC circuit when image brightness is insufficient due to limitation of a variable width of the stop. When an electronic magnification changing circuit is provided, a displacement speed of optical magnification change is detected on the basis of magnification changing data detected with the encoder, and control is performed at the same speed as this speed so that a shift is made to an electronic magnification changing operation.

摘要： The circuit according to the present invention is a signal transmission circuit for a solid-state image pickup device which performs favorable signal transmission by suppressing heat production around an image pickup device to a minimum level. This circuit is used for transmitting video signals output from a CCD to a signal processor of a processing unit by way of a transmission line, and comprises, at a stage subsequent to the CCD, a complementary circuit composed of two current controlling diodes, a first transistor, a second transistor and a plurality of resistors. This complementary circuit operates the first transistor and the second transistor alternately, thereby outputting video signals from the CCD as positive and negative signals taking 10 V, for example, as standard. Such an operation of class B eliminates a necessity to supply a bias current, thereby preventing heat production from the transistors and resistors due to application of a bias current.

摘要： The present application relates to an electronic endoscope apparatus for forming a preferable static image by controlling blurring of an image at the time of picking up the image by using a variable-power mechanism. This endoscope emits stroboscopic light by a stroboscopic light emission circuit when a freeze button is pressed and sets a high shutter speed shorter than an exposure time for a dynamic image by an electronic shutter circuit. Moreover, observation distances can be changed by moving a movable lens through a variable-power motor section and a linear transmission member in accordance with operation of a variable-power switch. Therefore, a static image is formed trough short-time image pickup by strong illumination light and image blurring is eliminated which becomes remarkable in particular when the image is enlarged through variable-power operation.
