REDUCING BLUR BASED ON A KERNEL ESTIMATION OF AN IMAGING DEVICE

A kernel estimation section (222) of an image processing device of the present invention is configured such that, when performing estimation of a blur kernel based on a contracted degraded image that has a first resolution, the kernel estimation section performs the estimation based on an initial value of a blur kernel that has a resolution corresponding to the first resolution. Thereafter, when performing estimation of a blur kernel based on a contracted degraded image that has a second resolution that is higher than the first resolution, the kernel estimation section performs the estimation based on an initial value of a blur kernel that has a resolution corresponding to the second resolution. The kernel enlargement section (223) extracts interest points of a blur kernel received from the kernel estimation section 222 (S16), performs an enlargement transformation on coordinates of the interest points (S18), and connects new interest points obtained by performing the enlargement transformation on the coordinates of the interest points (S20), thereby generating an initial value of a blur kernel that has an increased resolution (S22).
