1. An image processing apparatus comprising circuitry configured to: detect a degree of blur of an input image on the basis of the input image; select any of a plurality of image processing operations for subjecting the input image to processing by reducing an information amount of information included in the input image on the basis of a detection result of the degree of blur, wherein if a value indicating the degree of blur is equal to or larger than a predetermined threshold, the selection is made from a first group of determined image processing operations, and if the value is smaller than the threshold, the selection is made from a second group of predetermined image processing operations; and perform the selected image processing operation on the input image.
