Title: IMAGE COLLECTION METHOD AND DEVICE
Abstract:
Disclosed are an image collection method and device for quickly collecting different biological feature image information by means of an easily integrated device. The method in the embodiments of the present invention is applied to an image collection device. The method comprises: when it is detected by means of a distance sensor that an object is within a first collection distance, turning on a first light-compensation light source, wherein the first light-compensation light source is a light source for compensating light for a first biological feature; acquiring first biological feature image information by means of an imaging element; when it is detected by means of the distance sensor that an object is within a second collection distance, turning on the second light-compensation light source, wherein the second light-compensation light source is a light source for compensating a second biological feature; and acquiring second biological feature image information by means of the imaging element. The imaging element cooperates with a corresponding light-compensation light source when acquiring an image so as to acquire biological feature image information of high quality, and the image collection device uses one image element, thus reducing use of a plurality of imaging elements and facilitating integration of devices.
