 Maximum frame rate is up to 30fps@1920x1080③

 Bit rate supported is from 10Kbps to 20Mbps

1.2.7 JPEG CODEC

 JPEG decoder

 Input JPEG file : YCbCr 4:0:0, 4:2:0, 4:2:2, 4:4:0, 4:1:1 and 4:4:4 sampling

formats

 Output raw image : YCbCr 4:0:0, 4:2:0, 4:2:2, 4:4:0, 4:1:1 and 4:4:4

semi-planar

 Decoder size is from 48x48 to 8176x8176(66.8Mpixels)

 Maximum data rate is up to 76million pixels per second

 JPEG encoder

 Input raw image :

 YCbCr 4:2:0 planar

 YCbCr 4:2:0 semi-planar

 YCbYCr 4:2:2

 CbYCrY 4:2:2 interleaved

 RGB444 and BGR444

 RGB555 and BGR555

 RGB565 and BGR565

 RGB888 and BRG888

 RGB101010 and BRG101010

 Output JPEG file : JFIF file format 1.02 or Non-progressive JPEG

 Encoder image size up to 8192x8192(64million pixels) from 96x32

 Maximum data rate④ up to 90million pixels per second

1.2.8 Image Enhancement(inside video encoder/decoder in ON2)

 Image pre-processor(embedded inside video encoder)

 Only used together with HD video encoder inside RK3026 , not support stand-alone

mode

 Provides RGB to YCbCr 4:2:0 color space conversion, compatible with BT.601 ,

BT.709 or user defined coefficients

 Provides YCbCr4:2:2 to YCbCr4:2:0 color space conversion

 Support cropping operation from 8192x8192 to any supported encoding size

 Support rotation with 90 or 270 degrees

 Video stabilization(embedded inside video encoder)

 Work in combined mode with HD video encoder inside RK30xx and stand-alone

mode

 Adaptive motion compensation filter

 Support scene detection from video sequence, encodes key frame when scene

change noticed

 Image post-processor(embedded inside video decoder)

 Combined with HD video decoder and JPEG decoder, post-processor can read input

data directly from decoder output to reduce bus bandwidth
