PROBLEM TO BE SOLVED: To confirm whether a signal component to be recognized exists in a part to become the background part of an image or not without complicated operation. SOLUTION: The image analyzing device is provided with a color conversion table 82 for storing color data showing a color corresponding to each of densities of pixels, a color conversion table generating/updating part 84 for determining the starting point and ending point of the density in order to specify a concerned area showing the pixel to be displayed, applying the color data according to prescribed gradations to the respective densities between these points and writing the color data into the color conversion table corresponding to the respective densities and a display image generating part 72 for generating display image data composed of the color data by specifying the color data based on each of densities of respective pixels while referring to the color conversion table. The color conversion table generating/updating part 84 determines second starting and ending points concerning the densities of pixels in the background area of an area except for the concerned area, applies color data according to the other prescribed gradations to the respective densities between the second starting point and the second ending point and writes the relevant color data in to the color conversion table corresponding to the respective densities. |
