摘要： A method of controlling a digital photographing apparatus successively photographs one short exposure image and a plurality of long exposure images. A global motion of each of the long exposure images is compensated based on the one short exposure image. A Point Spread Function (PSF) of each of the one short exposure image and the long exposure images are extracted. A shake correction image is extracted through a repeat estimation by determining an initial value of the repeat estimation based on the one short exposure image and the long exposure images and using each PSF.

摘要： An image processing method and image processing apparatus for removing noise from an image. The image processing method includes: dividing an input image into a high frequency component and a low frequency component; removing noise from the high frequency component; and combining the low frequency component and the high frequency component from which noise is removed to form an output image. Accordingly, an image in which edge components are well preserved and a degree of color noise is reduced may be generated not only in a general environment but also in a low light level and highly sensitive environment having strong noise.
