Hi, I am Chae.
I am reading the sample_camera code of Intel Media SDK sample.
I want to operate vignette correction of Raw Accelerator.
but when I use vignette correction of sample_camera.cpp, VignetteMaskFile is required for using the correction.
So, I want to know what is Foramt of VignetteMaskFile and receive the sample MaskFile.
thank u.
FILE *maskFile; /* Load vignette mask from file */ MSDK_FOPEN(maskFile, pParams->strVignetteMaskFile, MSDK_STRING("rb"));

Hi Chae,
I checked the samples and document and I didn't find anywhere it specify this file and I will ask.
In the meantime, you can check the following code to reverse engineer the file format, it should be simple and I think it should use the common Vignette Mask file by the popular photo tools.
At the line 1078 the function CCameraPipeline::AllocAndInitVignetteCorrection() is the Vignette Mask file parsing logic.

Hi, Liu.
Thank u for your answer.
I have to create mask file myself?

Hi Chae,
I think you have to create your own, but I can ask.
Here is the file format I got:
For sample_camera input is bayer format (rg16, bg16, ..), output is .bmp (by default)
Let me know if you have questions.

Hi Liu.
Vignette correction mask must have 4channel(R, Gr, Gb, B) and 2Bytes(integer, mantissa) each channel..
So mask file is RAW format?
