Abstract
A display timing setting unit determines the timing of rendering an image by raster scanning. A pixel reading unit reads a pixel according to timing information output from the display timing setting unit. An area of interest information input unit enters information for identifying an arbitrary area of interest within an image. An area of interest identifying unit determines whether the pixel is included in the area of interest based on the timing information output by the display timing setting unit. A finite-bit generation unit generates a finite bit series by subjecting information on the pixel to mapping transformation when the pixel is included in the area of interest.
