Abstract:
A digital camera, comprising:means for setting a shutter speed; an optical system; an imaging device which receives a light flux from an object to be photographed, the light flux being passed through the optical system to form an image of the object to be photographed, at the shutter speed set by the shutter speed setting means, and converts the received light flux into an image signal; a variable gain amplifier that amplifies the image signal output by the imaging device with a variable gain; means for judging whether the shutter speed set by the shutter speed setting means is slower than a predetermined blur avoiding speed; means for increasing the gain of the variable gain amplifier to a predetermined value when the judging means judges that the shutter speed set by the shutter speed setting means is slower than the predetermined blur avoiding speed; and means for manually setting a value as the predetermined value for the gain of the variable gain amplifier.
