PROBLEM TO BE SOLVED: To provide an image acquiring means, etc., capable of accurately acquiring distance information to an object by eliminating factors of errors caused by the inclination of the surface of the object, etc. SOLUTION: The object is irradiated with light from three optically different irradiation locations or more. The reflected light from the object by the light shone from the three irradiation locations or more is each picked up. By computing the distance information on the basis of the picked-up reflected light, it is possible to eliminate factors of errors caused by the inclination of the surface of the object, etc., and to accurately acquire the distance information to the object, etc. By making different the waveform of the light shone from the three irradiation locations or more, it is possible to simultaneously perform irradiation and image pickup and accurately acquire the distance information, etc., on a moving object. By arranging the three irradiation locations in a straight line and making the image pickup location equal to any irradiation location, it is also possible to acquire the distance information, etc., on the object.
