  • Publication number: 20100209009
    Abstract: A digital camera carries out the following steps. The digital camera acquires one image photographed with a high sensitivity for subject-blur suppression, four images of a first group consecutive in a time series photographed with an ordinary exposure time, and four images of a second group consecutive in a time series photographed with an exposure time shorter than the ordinary exposure time for multiplane addition. Then, the digital camera extracts, from among the images photographed with the ordinary exposure time, an image for which blur caused by hand movement is minimum, and if no image blur has occurred and if blur caused by hand movement is less than a predetermined value, selects the image. The digital camera selects the image for subject-blur suppression if image blur has occurred for the extracted image. Also, the digital camera generates a new image by carrying out multiplane addition of images for multiplane addition if blur caused by hand movement has occurred for the extracted image.

  • Publication number: 20090284609
    Abstract: An image capture apparatus shifts an image sensor at each shooting initiation time in the continuous-shoot mode in the event of a camera-shake in response to a control signal which reflects an offset signal indicating pixel shifting information in a compensating signal indicating shake compensating information. Thereby, a change in the shooting range of the image sensor due to the camera-shake is mostly compensated for and the shooting range is changed by one pixel at each shooting. Thus, even in the event of a camera-shake, the distance between a feature portion of a main subject and a fixed pattern noise can be made different for each of continuously shot images. As a result, even in the event of the camera-shake, a composite image having fixed pattern noises scattered can be obtained by combining continuously shot images with reference to the feature portion.
