AIE Adaptive Image Enhancer Series
AIE:
Adaptive Image Enhancer
(Image processing technology based on ROHM hardware)
BU1570KN, BU1571KN
No.09060EBT01
●Description
BU1570KN/BU1571KN is AIE : Adaptive Image Enhancer (image processing technology by ROHM’s hardware).
Provides unprecedented visibility under severe conditions, such as darkness or extreme backlighting.
●Features
1) UXGA size (16001200) for input of image data up to 7.5 fps, SXGA size (12801024) for input of image data up to
15 fps and VGA size (640480) for input of image data up to 30 fps.
2) Input data format for YUV=4:2:2 8bit. Order of components may be adjusted by the register.
3) Operation modes are image enhance mode, through mode, and sleep mode.
4) Strength of image correction can be set to linear.
5) Able to read out brightness for the entire area for motion detection *1
6) Register can be set up with a 2-line serial interface.
*Extra document is prepared separately about each register setup. Please refer to the Development Scheme on page 6.
*1 : BU1570KN Only
