确定光照条件改变引起的需要改变像素密度要求的方法和设备
摘要：
本发明提供一种确定光照条件改变引起的需要改变像素密度要求的方法和设备。所述像素密度要求限定能使摄像机拍摄的图像中的目标被识别的像素密度。该方法包括：接收并且监控摄像机设置(S02)，所述摄像机设置表示所述摄像机经受的光照条件并且影响所述摄像机拍摄的图像的质量；以及在检测到所述摄像机设置改变时(S04)，确定需要改变像素密度要求(S06)。所述摄像机设置包括所述摄像机拍摄图像时使用的增益和曝光时间中的至少一个。本发明能够确定光照条件改变引起的改变像素密度要求的需要。
摘要（英）：

There is provided a method for determining a need for a change in a pixel density requirement due to changing light conditions. The pixel density requirement specifies a pixel density which enables identification of an object in images captured by a camera. The method comprises receiving and monitoring (S02) a camera setting which is indicative of a light condition to which the camera is subjected and which affects the quality of images captured by the camera, and determining (S06) that there is a need for a change in the pixel density requirement upon detection (S04) of a change in the camera setting. The camera setting includes at least one of a gain and an exposure time used by the camera when capturing images.
