1. A device for processing a camera image, the device comprising:
an image capture device configured to obtain an image; and
a processor configured to linearly control a first noise removal intensity according to an amount of sensor gain amplification in the image in a low-illumination environment,
wherein, based on recognizing an object in the image, the processor is configured to dynamically control a noise removal intensity between the first noise removal intensity and a second noise removal intensity lower than the first noise removal intensity according to a moving speed of the object.
