ABSTRACT:
A medical image processing apparatus includes a color video monitor (image displaying device) 3 and an arithmetic and control circuit 4. When the apparatus is supplied with electric power and begins to operate, the arithmetic and control circuit 4 causes a color density bar 32 and a color density bar 42 to be displayed in parallel on a display screen 3a l of the color video monitor 3. The color density bars 32, 42 each serve as a display adjusting image. The color density bar 32 is formed such that a density gradually becomes deep from an end of the bar 32 to the other end of the same. In the color density bar 42, it is deepened in a direction opposite to that of the color density bar 32.
