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.

Claims

1. A medical image processing apparatus comprising:

an image displaying device;

a system for processing medical images and for outputting the images to the image displaying device;

said processing system causing white and black background bars to be displayed in parallel on a display screen of said image displaying device when said medical image processing apparatus is turned on, said processing system having an arithmetic and control circuit which causes first and second density bars each serving as a display adjusting image to be displayed within said white and black background bars respectively; and

said processing system instructing said arithmetic and control circuit to generate said first density bar in which a density gradually varies from pale to deep from one area to another area of said first density bar and said second density bar in which a density gradually varies from pale to deep in a direction opposite to that of said first density bar.

2. A medical image processing apparatus according to claim 1, wherein said density bars are monochromes.

3. A medical image processing apparatus according to claim 2, wherein said density bars each comprises a plurality of adjacent squares of which densities are different from each other and a medical image is set to be displayed on said display screen without distortion when vertical and horizontal sizes of each of said squares are equal to each other.

4. A medical image processing apparatus according to claim 2, wherein said density bars each comprises a plurality of adjacent rectangles of which densities are different from each other.

5. A medical image processing apparatus according to claim 4, wherein said rectangles are formed with a longer vertical dimension than horizontal dimension in order to easily distinguish the density.

6. A medical image processing apparatus according to claim 1, wherein said density bars each comprises a plurality of adjacent squares of which densities are different from each other and a medical image is set to be displayed on said display screen without distortion when vertical and horizontal sizes of each of said squares are equal to each other.

7. A medical image processing apparatus according to claim 1, wherein said density bars each comprises a plurality of adjacent rectangles of which densities are different from each other.

8. A medical image processing apparatus according to claim 7, wherein said rectangles are formed with a longer vertical dimension than horizontal dimension in order to easily distinguish the density.
