Abstract
PURPOSE: To make it possible to attain measurements with extremely high precision and high accuracy by making registration at the optimum cursor brightness, by automatically or manually varying the brightness of the cursor corresponding to the contrast of a detected-body image.
CONSTITUTION: Outputs 103 and 104 of pulse generators MV1 and MV2 cause pulse generators MV3 and MV4 using monostable multivibrators to operate to generates outputs 106 and 107, whose pulse width corresponds to the bright-line width of cursors 3 and 4, and they are mixed MX1 and then outputted to gate GT2. The output of this gate GT2 is supplied to inversion circuit IV2, which outputs signal 112 of the opposite polarity to cursor signal 111, and potentiometer R3 outputs final cursor signal 113. Namely, the cursor brightness is varied manually or automatically corresponding to the contrast of a detected body and the registration is done at the optimum cursor brightness, so that measurements can be done with extremely high precision and high accuracy.
