AIE Adaptive Image Enhancer Series
Real Time
Video Processor ICs
BU1572GUW, BU1573KV, BU1574KU
●Description
BU1572GUW/BU1573KV/BU1574KU is AIE : Adaptive Image Enhancer (image processing technology by ROHM’s
hardware). Camera video images are optimized for maximum visibility.
●Features
1) Compatible with image data from QCIF size (176 144) up to WVGA+ size (864 480)
2) Compatible with 80-system CPU bus interface and RGB interface.(BU1572GUW/BU1573KV)
3) Compatible with Input/Output data formats with RGB 5:6:5 and 6:6:6.(BU1572GUW/BU1573KV)
4) Multiple operation modes: Image Enhance, Analysis, Through and Sleep. *1
5) Two selectable register settings: indirect addressing through the 80-system CPU bus interface
or the 2-wire serial interface (I
2
C) *2
6) PWM output for image adjustment LCD backlight control.
7) Built-in edge-enhancement and gamma filters.
*1: BU1574KU is an analysis mode setting interdiction.
*2: BU1574KU becomes only the register set by the two-wire system serial interface.
＊ Extra document is prepared separately about each register setup. Please refer to the Development Scheme on page 10.
●Application
Portable media player, Mobile phone, car display, Car navigation system, and portable DVD etc.

●Absolute maximum ratings (Ta=25℃) ●Recommended operating range
*In the case exceeding 25ºC, 3.1mW should be reduced at the rating 1ºC.
(BU1573KV: 7.5mW / BU1574KU: 7mW should be reduced at the rating.)
*1: BU1573KV is 750mW, and BU1574KU is 700mW.
