Abstract: Provided is a digital camera which can display an image quickly following a change in a position of an object with a small-sized, inexpensive construction at the time of picking up the image of the object in a low brightness. The digital camera is provided with an image pickup unit (110) for picking up an image of an object, a storage unit (130) for storing the image constructed by a signal outputted from the image pickup unit (110) and a control unit (150), which, in a case where the illuminance is less than a predetermined value when the image pickup unit (110) picks up the image of the object during the preview at a display unit (120) and also it is detected that any one of an entirety of the image, a specific object in the image or a digital camera body moves, sets each of a gain value and a frame rate to a value larger than a designed value for photography.
