To all m5603c users
This summer I have worked again on the m5603c.
I finally figured out the huffman tables for the jpeg. The tables below
give the same decoding tables that are in the windows drivers. Decoding
tables in the windows driver are mincode, maxcode and valptr (Figure
F.15 page 108 TO81e.doc). The DC is non standard. It does not have the
"1" as category value. The AC tables is standard. Tables are used as far
as I see for Y, Cb and CR.
I test it with the test-pattern from the mt9v011 sensor. I have a user
space program with reads the data from the usbfs system. Works just as
fast as the kernel driver.
There is still something wrong with the quality tables and maybe the
header settings. I am producing both 4:2:2 as well as 4:1:1 jpeg raw
data files.
DC table
unsigned char dht1[] =
{ 0xff,0xc4,0x00,0x1f, 0x00};
unsigned char bitsYDC[] =
{0, 1, 5, 1, 1, 1, 1 , 1, 1, 0, 0, 0, 0, 0, 0, 0, 0};
unsigned char valYDC[] = {0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};
AC table
unsigned char dht2[] =
{ 0xff,0xc4,0x00,0xb5, 0x10};
unsigned char bitsYAC[] =
{0, 2, 1, 3, 3, 2, 4, 3, 5, 5, 4, 4, 0, 0, 1, 0x7d};
unsigned char valYAC[] =
{ 0x01, 0x02, 0x03, 0x00, 0x04, 0x11, 0x05, 0x12,
