Abstract
Disclosed are an apparatus and a method of preventing image degradation due to shaking of an image photographing device. An apparatus for preventing image degradation due to shaking of an image photographing device according to an aspect of the present invention includes an image acquiring unit to acquire a plurality of images of a predetermined subject using a second exposure time shorter than a first exposure time, a scale adjusting unit to adjust scales of the plurality of acquired images, and an image restoring unit to restore images of the subject using the plurality of images whose scales are adjusted.
Claims14
An apparatus for preventing image degradation due to shaking of an image photographing device, the apparatus comprising:
- an image acquiring unit to acquire a plurality of images of a predetermined subject using a second exposure time shorter than a first exposure time;
- a scale adjusting unit to decrease a data size of acquired images by reducing scales of the plurality of acquired images;
- and
- an image restoring unit to restore images of the subject using the plurality of images whose scales have been reduced,
- wherein the scale adjusting unit reduces the scales of the acquired images using an average value among a predetermined number of pixel values in the acquired images and a ratio between the first exposure time and the second exposure time.
A method of preventing image degradation due to shaking of an image photographing device, the method comprising:
- acquiring a plurality of images of a predetermined subject using a second exposure time shorter than a first exposure time;
- reducing data size of acquired images by reducing scales of the plurality of acquired images;
- and
- restoring images of the subject using the plurality of images whose scales have been reduced,
- wherein the reducing of the scales comprises reducing the scales of the acquired images using an average value among a predetermined number of pixel values in the acquired images and a ratio between the first exposure time and the second exposure time.
