The invention relates to the technical field of intelligent terminals, and provides a light source position adjusting device and an adjusting method. The light source position adjusting device is usedfor adjusting the position of a light source and comprises a connecting assembly and a correcting assembly, the connecting assembly is used for being connected with the light source, the correcting assembly is used for generating lasers, the correcting assembly is connected with the connecting assembly, and a laser direction of the correcting assembly is consistent with the direction of a centerlight ray of the light source. The light source position adjusting device can be used for assisting in adjusting the position of the light source, so that the center light ray of the light source canbe emitted to a light sensor according to preset requirements, so that the position of the light source can be adjusted to meet the requirements, adjusting precision of the light source is greatly improved, and then correcting precision of the light sensor is greatly improved. The light source position adjusting device has the advantages of being simple in structure, small in size, convenient to carry, capable of being quickly and conveniently transferred to a needing field, effectively expanding the application field thereof, and at the same time being simple in application methods, convenient in operation, and convenient to popularize on a large scale.
