To color images obtained by means of laser radar equipment.

Laser power sources 11-13 for red, blue, green, and blue colors respectively emit red, green, and blue laser light rays 41-43 and a solid-state image pickup device 14 with amplifier performs photoelectric conversion on the reflected laser light rays 44 of the light rays 41-43 from an object 5 to be measured into electric signals corresponding to the red, green, and blue colors. An image processing section 23 generates a colored radar image by synthesizing the electric signals and displays the image on a monitor 3. In addition, a laser power source controller 21 causes the object 5 to be displayed in its original color by preventing the object 5 from being displayed in a reddish or bluish color by the influence of the moisture or contaminants in the measurement environment by controlling the intensities of the power sources 11-13 in accordance with the measurement environment.
