<P>PROBLEM TO BE SOLVED: To achieve both improvements in visibility of through-image and in operability. <P>SOLUTION: A through-image is displayed on an LCD monitor 36 by an LCD driver 34 after being processed at a preprocessing circuit 22 and a post-processing circuit 30. An icon is displayed on the LCD monitor 36 by a graphic generator 32 and the LCD driver 34. A CPU 44 repeatedly determines whether or not a finger of an operator is near a screen of the LCD monitor 36, in association with display processing of the through-image. The CPU 44 displays the icon based on a positive determination result, but it stops displaying the icon based on a negative determination result. The CPU also accepts touching operation for the displayed icon and changes a zoom magnification in a manner following the touch operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
