距離画像生成装置
Document Type and Number:
Japanese Patent JP5190721
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a distance image generation apparatus capable of generating a distance image with high accuracy.SOLUTION: A distance image generation apparatus comprises: a light-emitting source for radiating modulated light; an image pick-up element including a plurality of photoelectric conversion elements that receive light reflected by an object and convert the light into electric charges, a plurality of charge accumulating sections provided for the respective photoelectric conversion elements, and means that distributes the electric charges converted by the photoelectric conversion elements to the plurality of charge accumulating sections; a distance image generating section for performing predetermined operations based on the electric charges to generate a distance image whose pixel value is a distance value; light quantity adjusting means for adjusting light quantity; calculation means for calculating an amplitude value of a component of the light reflected by the object based on the electric charges; and counting means for counting the number of the photoelectric conversion elements. The light quantity adjusting means performs adjustment so as to reduce the quantity of modulated light from the light-emitting source when the number of the photoelectric conversion elements counted by the counting means exceeds a predetermined number.
