Abstract
A method, system and computer readable medium for controlling a digital camera including setting a shutter speed; receiving a light flux from an object to be photographed to form an image thereof at the set shutter speed; converting the received light flux into an image signal; amplifying the image signal with a variable gain; judging whether or not the shutter speed is set slower than a predetermined blur avoiding speed; and increasing the variable gain to a predetermined value when the shutter speed is set slower than the predetermined blur avoiding speed. Another embodiment includes a method, system and computer readable medium for controlling a digital camera including setting a shutter speed; receiving a light flux from an object to be photographed to form an image thereof at the set shutter speed; converting the received light flux into an image signal; amplifying the image signal with a variable gain; judging whether or not the shutter speed is set slower than a predetermined blur avoiding speed; selectively setting a photographing mode to one of: a blur avoiding photographing mode in which the variable gain is increased to a predetermined value when the shutter speed is set slower than the predetermined blur avoiding speed, and a normal photographing mode in which the variable gain is not increased even when the shutter speed is set slower than the predetermined blur avoiding speed; and increasing the variable gain to a predetermined value when the blur avoiding photographing mode is set and when the shutter speed is set slower than the predetermined blur avoiding speed.
