Abstract: A multi-viewpoint image which has been captured with respect to an object from a plurality of viewpoints is coded by setting a base viewpoint among the plurality of viewpoints. An image captured from a viewpoint that is not the base viewpoint is then coded using a reference image selected based on imaging parameters and a parallax.

Abstract: This invention decreases the count of access to a memory which stores image data regarding orthogonal transform, and quickly generates orthogonal transform coefficients. An apparatus includes a storage unit which stores image data, a memory controller which reads each block from the storage unit, a first transforming unit which receives and orthogonally transforms the input block, and calculates only one DC component, a selector which selects and outputs one of the block read out via the memory controller, and data of DC components from the first transforming unit that are equal in number to pixels included in the block, a second transforming unit which orthogonally transforms data that have been output from the selector and are equal in number to pixels included in the block, and outputs either one DC component or a plurality of AC components, and a controller which controls the memory controller, selector, and second transforming unit.

Abstract: This invention enables parallelly sorting data in substantially M blocks though statistical information is updated. In the first scan conversion, (15) input transform coefficients of a two-dimensional array are read out and output in accordance with scan order information ScanOrder[ ], thereby outputting sorted one-dimensional array data. At this time, a significant coefficient detection unit determines whether the sorted data is a significant coefficient. Upon receiving a notification that the sorted data is a significant coefficient, a statistical information update unit updates statistical information ScanTotals[x] at a corresponding position. When the relationship between statistical information ScanTotals[x] and immediately preceding statistical information ScanTotals[x?1] is an ascending order, ScanOrder[x?1] and ScanOrder[x], and ScanTotals[x?1] and ScanTotals[x] are swapped respectively.
