PURPOSE:To make it possible to designate image concn. with an oblique line and to display the image concn. on the designated oblique line in a short time by using a means designating a straight line on a monitor screen, judging the slope of said straight line and displaying the characteristic value of the endoscope image corresponding to the position of the straight line in the horizontal or the vertical direction. CONSTITUTION:When a treatment of profile graph display is started, a short cross- cursor 74 is displayed and after it is moved to an arbitrary position, a mouse is clicked and a starting point is determined. Then the end point is determined by moving and clicking the cursor 74 to obtain a straight line 73. Then the angle of inclination alphaof the straight line is calculated and it is easily obtd. by the ratio of the horizontal distance and the vertical distance between the starting point and the end point. A judgement on whether this angle alpha is smaller than 45 deg. is performed and if the value is 45 deg. or larger, the concn. level of an image data on the straight line 73 is set on an abscissa axis and a profile graph 75a is displayed in such a way that the concn. level is projected on the horizontal axis direction. On the other hand, the angle alphais smaller than 45 deg., the concn. level of an image data on the straight line 73 is set on an ordinate axis and the profile graph 75b is displayed in such a way that the concn. level is projected on the vertical axis direction. |
