The blur kernel determination unit changes the size of the blur kernel according to the exposure time during photographing.

The blur kernel deciding unit is operative to change the blur kernel size on the basis of information, such as the zoom scaling factor of the optical system (20), which has some effects on the degree of the image blur.

A method of reducing blurring in an image of size greater than M columns by N rows of pixels, comprises deriving a blur kernel k representing the blur in the image, and deriving an inverse blur kernel k-1.

The size of the lactone ring may be varied by either increasing or decreasing the ring size.

The image (75) can then be deblurred by deconvolution (79) with the derived blur kernel.

The construction prevents degradation of image blur correction performance of the image blur correction device and contributes to downsizing of the device.

In this way, as the amount of blur changes, the filter size changes appropriately.

In this way, as the amount of blur changes, the filter size changes appropriately.

Next, the defocus blur kernel size (520) can be estimated from the averaged autocorrelation matrix (572).

A blur kernel is then derived by extracting (78A) the identified specular highlight as foreground from the image (75) and using the extracted foreground as the blur kernel (78C).

A non-stationary blurring kernel may also be convolved at a plane closest to the detector face to generate a projection incorporating shift-variant blurring.

A method for reducing core size and core loss of the inductor is also provided.
