Abstract

本申请提供了一种双光图像自动曝光方法、装置、双光图像相机及机器存储介质，涉及相机技术领域，该方法应用双光图像相机，双光图像相机包括依次连接的图像传感器和处理器，其中，图像传感器的数量为一个，且双光图像相机还配置有红外截止滤镜；该方法由处理器执行，该方法包括：获取图像传感器采集的原始图像；对原始图像进行逻辑分光处理，得到红外图像和可见光图像；判断当前是否使用红外截止滤镜；如果使用红外截止滤镜，采用单光曝光算法对可见光图像进行曝光处理，以得到符合目标曝光效果的可见光图像；如果不使用红外截止滤镜，采用双光曝光算法对红外图像和可见光图像进行曝光处理，以得到符合第一曝光效果的可见光图像和符合第二曝光效果的红外图像；其中，第一曝光效果和目标曝光效果相同或不同。本申请可以为单传感器双光相机提供一种有效的曝光控制方式。
