An image processing apparatus includes a plurality of addition means and an image processing means. The addition means performs addition processing of adding pixels of a differential image at a second resolution representing a difference between an inputted image at a first resolution and an image at the second resolution higher than the first resolution as pixels of an inputted image at the second resolution. The image processing means is configured to perform second and subsequent addition processing, and generate an image of the second resolution as a processing result by performing the addition processing for a predetermined number of times. The addition processing is performed with inputs of an image at the first resolution and an image at the second resolution obtained by an immediately preceding addition processing, which are different from each other.

Image processing apparatus, image processing method and program

A parallel array architecture for a graphics processor includes a multithreaded core array including a plurality of processing clusters, each processing cluster including at least one processing core operable to execute a pixel shader program that generates pixel data from coverage data; a rasterizer configured to generate coverage data for each of a plurality of pixels; and pixel distribution logic configured to deliver the coverage data from the rasterizer to one of the processing clusters in the multithreaded core array. The pixel distribution logic selects one of the processing clusters to which the coverage data for a first pixel is delivered based at least in part on a location of the first pixel within an image area. The processing clusters can be mapped directly to the frame buffer partitions without a crossbar so that pixel data is delivered directly from the processing cluster to the appropriate frame buffer partitions. Alternatively, a crossbar coupled to each of the processing clusters is configured to deliver pixel data from the processing clusters to a frame buffer having a plurality of partitions. The crossbar is configured such that pixel data generated by any one of the processing clusters is deliverable to any one of the frame buffer partitions.

A system and method are disclosed for combining interactive gaming aspects into a linear story. A user may interact with the linear story via a NUI system to alter the story and the images that are presented to the user. In an example, a user may alter the story by performing a predefined exploration gesture. This gesture brings the user into the 3-D world of the displayed image. In particular, the image displayed on the screen changes to create the impression that a user is stepping into the 3-D virtual world to allow a user to examine virtual objects from different perspectives or to peer around virtual objects.

A multi-pass method of generating an image frame of a 3D scene, using a parallel graphics processing system having a plurality of graphics processing pipelines (GPPLs), including a primary GPPL. In the system, each GPPL includes a color frame buffer and Z depth buffer, and the GPPLs support an object-division based parallel graphics rendering process, in which the 3D scene is decomposed into objects that are assigned to particular GPPLs for processing. The multi-pass method involves, during a first pass, providing a Global Data Map (GDM) to the Z depth buffer of each GPPL. This step involves the transmission of graphics commands and data for all objects in the frame, to all GPPLs to be rendered. Then, during subsequent passes, a complementary-type partial image is generated within the color buffer of each GPPL using the GDM and a Z test filter supported by the Z depth buffer, and transmitting graphics commands and data of objects in the image frame, to only assigned GPPLs. After subsequent passes are performed, a complete color image is recomposited within the primary GPPL, using the complementary-type partial images stored in the color buffers of the GPPLs, without comparing depth values in the Z depth buffers.
