I have configured all parameters according to the adv212 user_manual and adv202_hipimode_still_image technical paper,All thing seem work well,but the compressed image (exported j2c fifle) from the encode system doesn't match the original image.
In fact, the contour of the compressed image (j2c fifle) agree with the original image , but pixels' values flippe, originally the high pixel values in compressed image display as black.
The exact parameters are configured as follows.
1)Encode Parameters
PLL_HI: 0008H
PLL_LO: 0006H
BUSMODE: 0025H(16 bit)
MMODE: 0005H(16 bit)
-----Configure Encode Parameters----------------
0402H
0503H
0300H
0000H
0100H
0888H
0000H
0001H
------------------------------------------------
PMODE1: 0418H
XTOT: 0080H(128)
YTOT: 0100H(256)
F0_START: 0001H
VMODE: 0012H
EIRQIR: 0400H
EDMOD0: 0110H
EDMOD0: 0111H
EDMOD1: 0112H
EDMOD1: 0113H
3)I use ADV212 with MCLK=20MHz
4)I input 128*256 16bit single component raw data (actually 14 bit，use hdata[13:0],hdata[15:14]=0)to encode ADV212 by hipi mode
5) I use kdu soft and matlab imread function to decode j2c file,they display the same
By now, I don't know how to deal with this problem,Could you give me some advice? I'm eager for your help. Thanks a lot.
