A depth image conversion unit moves an edge location in an input depth image towards a background. A pixel shift unit generates an image from a different viewpoint by horizontally shifting coordinates of each pixel in an image based on a converted depth image. A pixel interpolation unit interpolates a missing pixel region yielded by pixel shifting.

Image processing device, image processing method, program, and integrated circuit

An image processing device () includes: a representative pixel value storage unit () which selects one of plural sub-pixels as a representative sub-pixel, and store, into a representative pixel value storage area, a representative pixel value which is a pixel value of the representative sub-pixel; and a sub-pixel value storage unit () which stores, into a sub-pixel value storage area, pixel values of sub-pixels other than the representative sub-pixel, wherein the sub-pixel value storage area stores one or more sets corresponding to N number of pixels, the one or more sets each including a pixel position and a pixel value of each sub-pixel other than the representative sub-pixel of a pixel at the pixel position, N being a natural number smaller than a total number of the plural pixels in the unit of processing for an edge determination unit ().

A plasma display system restricts peak data traffic when a shared memory is used. In the plasma display system, a control unit prohibits a moving picture decoder from accessing a shared memory while an SF reading unit is reading, from the shared memory, SF pixel data which is information about respective cells to be lit in a plurality of subfields. On the other hand, the control unit permits the moving picture decoder to access the shared memory while the SF reading unit is not reading the SF pixel data from the shared memory during a sustain discharge period.
