Claim:
1. A method for controlling shutter speed and digital gain of a digital camera, comprising: detecting, by a luminance sensor of the digital camera, a luminance level of light entering the digital camera; determining if the luminance level is below a predefined luminance threshold; responsive to determining that the luminance level is below the predefined luminance threshold, detecting if motion meeting a predefined motion criteria is present in image frames captured by the digital camera; responsive to determining that the luminance level is not below the predefined luminance threshold or determining that the motion meeting the predefined motion criteria is not present in the image frames, controlling the digital camera to operate with a default shutter speed and a default digital gain; responsive to detecting that the motion meeting the one or more predefined motion criteria is present in the images frames captured by the digital camera, controlling the digital camera to operate with an adjusted shutter speed and an adjusted digital gain, the adjusted shutter speed and the adjusted digital gain resulting in a same exposure value as the default shutter speed and the default digital gain.
