Abstract:
1. An image processing apparatus for decoding a coded stream and outputting a decoded stream, comprising: a plurality of decoding means, for each frame divided into a plurality of predetermined regions equal to the number of decoding means each decoding means performing decoding processing on one predetermined region of each divided frame forming the coded stream; and output means for receiving a plurality of pixel data obtained as a result of the decoding processing performed by the plurality of decoding means and combining the plurality of pixel data into decoded image data and for outputting the decoded image data, wherein, among the plurality of decoding means, one decoding means supplies, among pixel data obtained as a result of the decoding processing performed by said one decoding means, pixel data necessary for a future decoding processing performed by another decoding means to said another decoding means, and also obtains, among pixel data obtained as a result of the decoding processing performed by said another decoding means, pixel data necessary for a future decoding processing performed by said one decoding means from said another decoding means, and said one decoding means performs the decoding processing by referring to the pixel data obtained as a result of the decoding processing perform by said one decoding means and the pixel data obtained in advance from said another decoding means, wherein boundary areas of adjacent predetermined regions are decoded before non-boundary areas of the adjacent predetermined regions such that each decoding means first performs decoding processing for a boundary area of the predetermined region with the adjacent predetermined region which is to be supplied to another decoding means before finishing decoding processing on a remaining area of the predetermined region such that some of the decoding means decode the predetermined region from a top of the predetermined region to a bottom and remaining decoding means decode the bottom of the predetermined region before the top.
