Video Accessory IC Series

For portable image equipment

Upscaler IC

BU1521GVW

●

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.
