Image processing apparatus and method and program

An image processing method comprising:

• an image pickup step of picking up an image by controlling an image pickup device;
• a vibration amount output step of detecting exerted vibration and outputting a vibration amount indicating a size of the vibration;
• a calculation step of calculating a first correction amount for reducing influence of the vibration to the image from the vibration amount output in the vibration amount output step;
• a determination step of determining whether or not a zoom magnification ratio at a time that the image is picked up in the image pickup step is equal to or higher than a predetermined threshold;
• a generation step of generating a second correction amount based on the first correction amount when the zoom magnification ratio is determined to be equal to or higher than the threshold value in the determination step;
• and
• a correction step of correcting the image picked up in the image pickup step based on the first correction amount or the second correction amount.
