hi, Alex
thanks for reply. i am a ISP algorithm engineer. i use libraw for read dng and cr2 files for algorithm tunning.
usually sensor will output raw data in some bit width, such as 10bit, 12bit 14bit in mipi interface. which bit information will be used in my c-model.
as you mentioned, Libraw provides maximum value in imgdata.color.maximum. for 14bit sensor output, i see the maximum value will be 0x3f60, which is less than 0x3fff. so may i need write some codes to detect the highest non-zero bit so that i can know the real bits (14 in this case)in 16 bit data.
anyway, thanks for you reply. libraw is really helpful for me. thanks verymuch
