  • Patent number: 9483813
    Abstract: An image processing apparatus that can be connected to a display device and removes blurring from a first-order image is provided. The image processing apparatus includes a generation unit, a display control unit, and a selection reception unit. The generation unit generates multiple I-th order intermediate images by performing blur correction in multiple blur directions on an I-th order image. The display control unit causes the multiple I-th order intermediate images to be displayed on the display device. The selection reception unit allows the user to select an (I+1)-th order image from among the displayed multiple I-th order intermediate images as a corrected image whose blurring has been reduced more than in the I-th order image. The generation unit, the display control unit, and the selection reception unit execute the above processing in order with respect to I=1, 2, . . . , K (K being a natural number).

  • Patent number: 9395887
    Abstract: An image processing apparatus for removing noise from a frame group on a timeline is provided. This image processing apparatus includes a judgment unit, a division unit, and a removal unit. The judgment unit judges whether changing points where there is a large change between adjacent frames included in the frame group appear at roughly the same interval along the timeline. The division unit, in a case where it is judged that the changing points appear at roughly the same interval, divides the frame group into a plurality of groupings along the timeline in accordance with the interval. The removal unit removes noise from the frame group in units of the groupings.
