<P>PROBLEM TO BE SOLVED: To improve the precision of visibility of an operator to execute a calibration more precisely by the visual observation of the operator. <P>SOLUTION: When a control section 11 makes a display section 13 display N-pieces test patterns, it makes one pattern to be switched and displayed on one screen respectively. Also, the control section changes the size of each display region which forms the test pattern corresponding to the size of the display screen so that the ratio of an area of the display region in which the driving level divided into N-pieces equal parts is set to an area of the other display region is 7:3, that is, the area of the display region displayed with the low intensity level becomes larger, and makes the test pattern with the changed size display on the whole display screen of the display section 13. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
