Abstract: PURPOSE:To stabilize a floating position and to obtain a stable observation image by detecting the displacement position of deflection of an insert part which is floating with the thrust of the jet injection of liquid and controlling the displacement position to zero. CONSTITUTION:A deflection detecting means which detects the deflection displacement position of the tip-side part of the insert part in the floating state is incorporated in an endoscope, and an image of a visual field A observed through an objective optical system 5 is photographed by an image pickup means 24 such as a TV camera mounted on the ocular part of the endoscope and observed on a TV monitor. The position of a reference point P in the image when the reference point P is set to a set point in the screen is denoted as (X0,Y0) and regarded as a target value (set point on the monitor image screen). The difference between a current position (X,Y) and the target value (X0,Y0) is calculated to find the deviation (DELTAX,DELTAY) as a movement quantity on the monitor screen and the manipulated variable of an injection direction control is so performed to control the displacement position to zero. Consequently, the floating position of the insert part can be stabilized. Thus, a stable observation image is obtained.

Filed: 1988-04-28
Abstract: PURPOSE:To execute a color measurement without generating the overflow of a register by providing a photoelectric converting part, an A/D converting part, a prescribed value discriminating means and a photoelectric conversion output adjusting means. CONSTITUTION:In a photoelectric converting part 1, a reflected light from a sample which has been irradiated by a light source is resolved into fundamental color components, and each component light is brought to photoelectric conversion. Subsequently, the light quantity is converted to a digital value by an A/D converter 4 and color information is obtained. Depending on a characteristic of a sample S, sometimes a peak P is generated in a light receiving angle and a reflected light luminance distribution and a register for converting to a digital value overflows. In this case, a CPU 5 compares an output of the A/D converter 4 with a prescribed value by utilizing a ROM 6 and a RAM 7, and when said output exceeds the prescribed value, an output signal of the converter 4 is decreased by adjusting an optical output of a light source Xe. According to such constitution, there is no fear of an overflow of the register, and the color measurement can be executed.
