Video data processing device and video data display device having a CPU which selectively controls each of first and second scaling units

摘要

A video data processing device which includes a bus, a central processing unit (CPU), a first scaling unit which is coupled to the bus and has an input unit for inputting image data from an external device, and a second scaling unit which is coupled to the bus. The CPU selectively controls the first scaling unit to convert the image data when an amount of the image data is decreased by a conversion performed by the first scaling unit, and selectively controls the second scaling unit to convert the image data when an amount of the image data is increased by the conversion performed by the first scaling unit.
