Abstract: An apparatus for monitoring an object in a low light environment includes an image capturing unit, a vehicle speed unit, an image recognizing unit, and an object determining unit. The image capturing unit continuously captures and outputs time-sliced images. The vehicle speed unit detects and outputs current vehicle speed information. The image recognizing unit recognizes a region having pixel brightness higher than a threshold in each of the time-sliced images and marks the region as a high brightness block. The object determining unit selects at least two successive time-sliced images having high brightness blocks in a continuous corresponding variation relationship from the time-sliced images, generates and outputs estimated speed information, and when the estimated speed information is different from the current vehicle speed information, determines that the high brightness block is a moving object block and monitors the moving object block.
