<p>PURPOSE:To display or extract a signal due to object to be observed with a high resolution by multiplying a signal to show a region with high likelihood of existence of the object to be observed with the observation data, or a signal due to the object observed obtained through calculating on the basis of this data. CONSTITUTION:Data given by an adding device 22 is assumed as a signal representing a region with high likelihood of existence of the object to be observed, and is left out of service as it is, and the signal value given by this adding device to a memory 24 is multiplied by a multiplier 25 with a signal fed to an auto signal emphasizing device 2 via an input terminal 2d, and the result therefrom is emitted from the output terminal 2e of the emphasizing device 2. As data showing high resolution, in this manner, multiplication 25 is made with the observation data obtained from the latest run of observation, or a signal due to the object observed obtained through calculation on the basis of this observation data, and only the real region where the object observes exists, is emphasized. Thus bleeding on the display screen is removed, signal due to object observed can be caught with high resolution highly reliably.</p> |
