1. An apparatus to compress a dynamic range of an image, the apparatus comprising: a periphery value production unit to calculate periphery information about peripheral pixels on a polyhedron-by-polyhedron basis using summed area tables produced from an analog pixel stream of a previous frame of the image, multiply the periphery information by predetermined weight values, sum results of the multiplications, and output the sum as a periphery value; and a pixel value correction unit to correct a pixel value of a target pixel that is included in an analog pixel stream of a current frame using the periphery value, and output a result of the correction; wherein the peripheral pixels are located around the target pixel and included in the previous frame, and a kernel distribution expressed in a kernel function, which is a distribution of weight values which depend on locations of pixels included in the image, is approximated to a sum of the polyhedrons.
