BRIEF

RK3026

 Also work as a stand-alone mode, its input data is from a camera interface or other

image data stored in external memory

 Input data format :

 any format generated by video decoder in combined mode

 YCbCr 4:2:0 semi-planar

 YCbCr 4:2:0 planar

 YCbYCr 4:2:2

 YCrYCb 4:2:2

 CbYCrY 4:2:2

 CrYCbY 4:2:2

 Ouput data format:

 YCbCr 4:2:0 semi-planar

 YCbYCr 4:2:2

 YCrYCb 4:2:2

 CbYCrY 4:2:2

 CrYCbY 4:2:2

 Fully configurable ARGB channel lengths and locations inside 32bits, such as

ARGB8888,RGB565,ARGB4444 etc.

 Input image size:

 Combined mode : from 48x48 to 8176x8176 (66.8Mpixels)

 Stand-alone mode : width from 48 to 8176,height from 48 to 8176, and

maximum size limited to 16.7Mpixels

 Step size is 16 pixels

 Output image size: from 16x16 to 1920x1088 (horizontal step size 8,vertical step

size 2)

 Support image up-scaling :

 Bicubic polynomial interpolation with a four-tap horizontal kernel and a

two-tap vertical kernel

 Arbitrary non-integer scaling ratio separately for both dimensions

 Maximum output width is 3x input width

 Maximum output height is 3x input height

 Support image down-scaling:

 Arbitrary non-integer scaling ratio separately for both dimensions

 Unlimited down-scaling ratio

 Support YUV to RGB color conversioin, compatible with BT.601-5, BT.709 and user

definable conversion coefficient

 Support dithering (2x2 ordered spatial dithering for 4,5,6bit RGB channel precision

 Support programmable alpha channel and alpha blending operation with the

following overlay input formats:

 8bit alpha +YUV444, big endian channel order with AYUV8888

 8bit alpha +24bit RGB, big endian channel order with ARGB8888

 Support deinterlacing with conditional spatial deinterlace filtering, only compatible

with YUV420 input format

 Support RGB image contrast / brightness / color saturation adjustment

 Support image cropping & digital zoom only for JPEG or stand-alone mode

 Support picture in pcture

 Support image rotation (horizontal flip, vertical flip, rotation 90,180 or 270

degrees)

1.2.9 Image Enhancement(New IEP lite module)

 Image formatsupport

 Input data: XRGB/RGB565/YUV420/YUV422

 Output data: ARGB/RGB565/YUV420/YUV422

 ARGB/XRGB/RGB565/YUV swap

 UV SP/P
