PROBLEM TO BE SOLVED: To reduce a manufacturing cost of a ranging device by increasing the number of total segments of an optical sensor array. SOLUTION: An imaging light flux by a pair of imaging lenses L and R is imaged on the optical sensor arrays 102L and 102R respectively. A calculation part 104 calculates by reading an imaging state by each imaging lens L and R from the output signals of the optical sensor arrays 102L and 102R to calculate a distance from an object to be measured. The imaging lenses L and R are droplets of liquid-like lenses. The liquid-like lens can moves each imaging lens L and R in a vertical direction to directions of optical axes SL and SR of each imaging lens L and R. COPYRIGHT: (C)2007,JPO&INPIT |
