Image stabilizing apparatus, image pick-up apparatus and image stabilizing method

An image stabilizing method comprising:

• calculating a motion vector between a plurality of images including a displacement caused by a motion of an image-pickup apparatus;
• receiving the motion vector as input to calculate a shake correction amount;
• and
• performing geometric transformation of an image in accordance with the shake correction amount,
• wherein receiving the motion vector includes:
• calculating accumulated variation amounts from an initial image of a sequence of images, the accumulated variation amounts being calculated based on image variation amounts calculated between a current image and a past image and between past images at different points of time;
• and
• calculating the shake correction amount based on the accumulated variation amounts, and
• wherein calculating the shake correction amount includes:
• transforming the accumulated variation amounts into at least one of components of horizontal translation, vertical translation, in plane rotation, horizontal foreshortening, and vertical foreshortening.

A non-transitory storage medium storing a computer program which, when executed by a computer, causes the computer to perform an image stabilizing method comprising:

• calculating a motion vector between a plurality of images including a displacement caused by a motion of an image-pickup apparatus;
• receiving the motion vector as an input to calculate a shake correction amount;
• and
• performing geometric transformation of an image in accordance with the shake correction amount,
• wherein receiving the motion vector includes:
• calculating accumulated variation amounts from an initial image of a sequence of images, the accumulated variation amounts being calculated based on image variation amounts calculated between a current image and a past image and between past images at different points of time;
• and
• calculating the shake correction amount based on the accumulated variation amounts, and
• wherein calculating the shake correction amount includes:
• transforming the accumulated variation amounts into at least one of components of horizontal translation, vertical translation, in-plane rotation, horizontal foreshortening, and vertical foreshortening.
