DIGITAL CAMERA, ELECTRONIC DEVICE EQUIPPED WITH DIGITAL CAMERA, IMAGING METHOD FOR DIGITAL CAMERA AND STORAGE MEDIUM PROVIDED WITH PROGRAM OF DIGITAL CAMERA
First Claim
1. A digital camera comprising:
- a body;
a storage unit;
an image pickup unit for picking up an image of an object at regular intervals in a preview mode, and outputting a signal indicative of the image, the image taken by the image pickup unit being stored in the storage unit; and
a control unit or a control unit and a direction monitoring unit provided with a function for changing a gain value of the signal outputted from the image pickup unit and a function for determining whether or not an entirety of the image, a specific object in the image or the body stops moving in the preview mode, whereinthe control unit sets the gain value of the signal to a designed value when the object is larger in illuminance than a predetermined value, or not moving with respect to the body, and increases the gain value of the signal when the object is lower in illuminance than the predetermined value, and moving with respect to the body.

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.

6. An image pickup method of a digital camera provided with an image pickup unit for picking up an image of an object and a control unit for controlling an image constructed by a signal outputted from the image pickup unit comprising:
-
an illuminance determining step in which the control unit determines whether or not the illuminance at the time of picking up the image of the object at the image pickup unit during the preview is lower than a predetermined value; an object determining step in which the control unit determines whether or not any one or more selected out of an entirety of the image, a specific object in the image or a body stops moving in a case where the control unit determines that the illuminance is lower than the predetermined value at the illuminance determining step; and a step in which the control unit increases a gain value to a value larger than a designed value for the photography during the preview in a case where the control unit determines that any one or more selected out of the entirety of the image, the specific object in the image or the body does not stop moving at the object determining step. - View Dependent Claims (7, 8, 9, 10, 11, 12)
