Patent number: 7239342Abstract: An object of the present invention is to generate an image which is prevented from being influenced by a movement while suppressing increase in noise components. When a movement is detected during exposure of an image capturing device to light, an image capturing apparatus stops the exposure of the image capturing device and amplifies an image signal obtained with the exposure, thereby compensating exposure shortage. Luminance information is extracted from a captured image, and color information is extracted from a live view image obtained at a timing different from a timing at which the captured image is obtained. By synthesizing the luminance information of the captured image and the color information of the live view image, noise components included in color information are reduced.Type: GrantFiled: May 28, 2003Date of Patent: July 3, 2007Assignee: Minolta Co., Ltd.Inventors: Yasuhiro Kingetsu, Kenji Nakamura
