1. An information reproduction apparatus comprising:
- a graphics processing unit to execute graphics processing including blend processing of superimposing respective planes of at least video data, picture data and graphics data to generate a graphics screen image; and
a partial blend control section to control the graphics processing unit to assure that data in a region except a specific region surrounding the graphics data is not used for the blend processing but data in the specific region is used for the blend processing, when the graphics data varies with time and occupies only a part of the entire plane.

Abstract
According to one embodiment, there is provided an information reproduction method that includes executing graphics processing including blend processing of superimposing respective planes of at least video data, picture data and graphics data, and performing control to assure that data in a region except a specific region surrounding a part superimposed on the video data or the picture data in the graphics data is not used for the blend processing but data in the specific region is used for the blend processing when the video data and the picture data vary with time and the graphics data does not vary with time.
