Patent attributes
Embodiments of the present invention disclose an image capturing method and device, so as to capture different types of biometric characteristic image information rapidly by using a device that can be integrated easily. The method according to the embodiment of the present invention is applied to an image capturing device, and the method includes: turning on a first supplementary lighting source when it is detected through a range sensor that there is an object in a first capturing distance, the first supplementary lighting source being a light source for supplementarily lighting a first biometric characteristic; acquiring first biometric characteristic image information through an imaging element; turning on a second supplementary lighting source when it is detected through the range sensor that there is an object in a second capturing distance, the second supplementary lighting source being a light source for supplementarily lighting a second biometric characteristic; and acquiring second biometric characteristic image information through the imaging element. When acquiring an image, the imaging element cooperates with a corresponding supplementary lighting source, so as to acquire high-quality biometric characteristic image information. Moreover, the image capturing device uses one imaging element and avoids using multiple imaging elements, thus facilitating integration of the device.
