Abstract: An image capture device includes a frame buffer, a processor, a shutter, an actuator, a three-axis optical motion sensor and an image sensor. The image sensor defines an optical axis. The three-axis optical motion sensor provides information concerning rotational movement of the camera about each of a roll axis, a yaw axis and a pitch axis. The roll axis is parallel to the optical axis. The yaw axis and the pitch axis are orthogonal to one another and orthogonal to the roll axis. The actuator rotates the image sensor in response to the rotational movement of the device about the optical axis. The processor generates first and second offsets responsive to the rotational motion about the yaw axis and the pitch axis. The processor shifts each line of image information in a frame in accordance with the first and second offsets.

Abstract: A method and apparatus for correcting for a distortion in a mammogram. The method comprises classifying pixels as either likely fat or likely not-fat. The method further comprises identifying a candidate distortion and calculating a histogram of the likely fat and the likely not-fat pixels at the candidate distortion. The method further comprises evaluating a quality of the candidate distortion based on features of the histograms of pixel values in the fat and dense tissue classes. The distortion may be a two dimensional tilt of the plates or a three dimensional deformation of the plates as in a bend.
