For portable image equipment
Upscaler IC
BU1521GVW
No.09069EAT02
● Description
BU1521GVW upscales and interpolates images when upconverting to the HDTV (Maximum 1080P) format from the usual SDTV
(NTSC/PAL) format.
High quality IP change・up scale management is realized by the frame memory less operate.
It is the LSI which is the most suitable for the compact system of the mobile.
