some questions about how to use DCC tuning tools

Peter Fan62

hi,

There are some questions about DCC, as follow:

(1) I get the information as that there is no header and foot in the data of YUV format save from DCC and the data is saved as YUV420SP(YYYY…UVUV…). However I can't show the right grayscale images when I get the first 1920*1080 data as Y from the *.yuv file.(PS: my picture is 1920*1080) I read the each data as uint8. I want to know whethet there are some wrong steps I take which lead me to get wrong image.

(2) the other question is about the exposure stepsize. I want to know the reason that we need to use 500,000 not other values in the following code.

What is the size in bytes of the YUV file?

I have read the yuv file. The count of the data as uint8 is 3,110,400(420SP:1920×1080×1.5). However, I read the Y is 1984×1096. Could you tell me the reason for that the count of Y is 1984×1096 and the UV just (1920×1080×1.5 - 1984×1096)?
