An image processing device which generates an image where a target object can be discriminated from an object other than the target object. An image processor 15, for echo signals read from a sweep memory 14, calculates a ratio of echo signals indicating a predetermined level or higher among the echo signals of a predetermined number of samples, and generates image data having a display element according to the calculated ratio. This ratio indicates a lower value as it indicates an object more isolated, such as a ship, and a higher value as it indicates an object existing as a larger mass, such as inland. The image processor 15 acquires color values (values of R, G and B) according to the calculated ratio. Since the target object, such as a ship, is an isolated object and the ratio becomes low, the color values indicate red, and since inland is an object existing as a large mass and the ratio becomes high, the color values indicate green. |
