PROBLEM TO BE SOLVED: To easily and surely specify an area suspected of an abnormal tissue on a normal color endoscopic picture. SOLUTION: When judging an abnormal pixel, an abnormality judgment circuit 51 outputs an abnormality judgment signal, takes pictures in a synchronization memory F24d, a synchronization memory G24e and a synchronization memory R24f at the time into a temporary memory 53, and controls an abnormal position display circuit 52. Thus, the abnormal position display circuit 52 superimposes and displays a mark showing a position of the abnormal pixel on the picture taken into the temporary memory 53, and outputs still picture data of a normal picture superimposed with the mark and stored in the temporary memory 53 to D/A conversion circuits 27a to 27c to thumbnail-display it on a monitor 4.
