Disclosed herein is a memory access control circuit including: a determination section adapted to determine whether a target requested by a first wraparound memory access request from a processor is stored in a prefetch buffer; a request generation section adapted to generate a second wraparound memory access request including the target if it is determined that the target is not stored in the prefetch buffer; and an address conversion section adapted to convert the start address of the first wraparound memory access request according to predetermined rules for use as a start address of the second wraparound memory access request.

There is provided a three-dimensional image reconstructing apparatus for reconstructing a three-dimensional image of an object. The three-dimensional image reconstructing apparatus includes an image-capturing section that captures a plurality of transmission-type images each of which is represented by densities of different levels, a characteristic region selecting section that selects a plurality of characteristic regions in each of the transmission-type images, a characteristic region distribution calculating section that calculates a spatial distribution of the characteristic regions based on respective positions of the characteristic regions, in each of the transmission-type images, and a three-dimensional image reconstructing section that, when reconstructing the three-dimensional image which shows the three-dimensional structure of the object and in which the densities of different levels are allocated to the whole object by integrating the transmission-type images, allocates the densities of different levels of the transmission-type images to respective positions, in the three-dimensional image, of the characteristic regions based on the spatial distribution of the characteristic regions, so as to reconstruct the three-dimensional image in which a three-dimensional structure in each of the characteristic regions is shown.
