The present application provides a face image acquisition device and method, wherein the device includes: an image sensor, a light fill device, a filter assembly and an image processor. The image sensor generates and outputs a first image signal and a second image signal through multiple exposures, and the first light supplement device included in the light supplement device performs near-infrared supplementary light, and performs near-infrared supplementary light at least within the exposure time period of the first preset exposure. Infrared supplementary light, no near-infrared supplementary light is performed within the exposure time period of the second preset exposure; the first filter included in the filter assembly allows visible light and part of near-infrared light to pass through; the image processor is used to process the first image signal and performing image processing and face detection with the second image signal to obtain a face image. In this technical solution, only one image sensor is needed to obtain visible light images and infrared light images, which not only reduces the cost, but also improves the quality of human face images.
Description
technical field [0001] The present application relates to the field of information processing technology, and in particular to a face image acquisition device and method. Background technique [0002] With the rapid development of science and technology, the application of safety protection products has been applied to various fields, such as government departments, large enterprises, communities and families. Among them, the monitoring system is an important part of security protection products, and image acquisition can provide a source for subsequent data analysis to meet the different needs of various application scenarios. [0003] If the face recognition camera is used to obtain the face image detected by the monitoring system. Specifically, the image acquisition circuit in the face recognition camera first collects visible light images and infrared light images through two image sensors, secondly performs fusion processing on the visible light images and infrared lig...
