A divided-area-based rendering device includes: a table generating unit that calculates, for each unit polygon, a first area including the unit polygon, using screen coordinates, determines, from among divided areas obtained by dividing a rendering region, a divided area including at least part of the first area, and generates an area-by-polygon table that is a table in which, for each unit polygon, the divided area including the at least part of the first area including the unit polygon is associated with the unit polygon; a determining unit that determines a rendering unit polygon that is one of the unit polygons which is associated with the divided area, by referring to the area-by-polygon table; and an area rendering unit that performs, for each divided area, vertex processing and rasterization on the rendering unit polygon. |
