  • Publication number: 20120287295
    Abstract: An image pickup apparatus capable of reducing camera-shake blur and rolling-caused distortion of image data obtained by shooting without including invalid data. An object obtained by shooting is stored in a memory area as first image data, and data having a smaller data size than the first image data is acquired as second image data by clipping from the memory area. A clipping position which enables correction of camera-shake blur is calculated according to an amount of movement due to a camera shake. Range information indicative of a range in the memory area and shift amounts used for correcting rolling-caused distortion are calculated. Rolling-caused distortion of the second image data is corrected based on the calculated shift amounts.

  • Patent number: 8189066
    Abstract: An image processing apparatus includes an evaluation value calculation unit configured to acquire an evaluation value from image data, a reduction coefficient calculation unit configured to calculate a reduction coefficient based on the evaluation value, a reduction unit configured to subject the image data to image processing to reduce color bleeding in a target area in the image data based on the reduction coefficient, and a size change unit configured to change the size of the image data. The reduction coefficient calculation unit calculates the reduction coefficient to reduce the color bleeding in a target area in the image data when the evaluation value exceeds a threshold.
