DM6446 resizer output data loss

Hi All,

We are using DM6446 for our camera.

Camera captures XGA (1024x768) YUV 4:2:2 data.

As DM6446 supports max D1 at 30 FPS, we resize this XGA data to D1 (720x480) using resizer of DM6446.

But what we see is, right bottom portion of the XGA image is cropped in resizer.

I have placed XGA.yuv (capture image) and D1.yuv (resized image) for your reference.

I have done mask on (974, 718) to (1015, 745) pixel with gray color.

We can clearly see the difference in size of this mask region in both the image as well as difference in position of the mask.

Here are my coefficients for resizer :

short gRDRV_1024x768to720x480H[] =
{ 25, 206, 25, 0, 12, 200, 44, 0, 5, 183, 68, 0, 1, 157, 98, 0, 0, 128, 128,
0, 0, 98, 157, 1, 0, 68, 183, 5, 0, 44, 200, 12
};

short gRDRV_1024x768to720x480V[] =
{ 31, 194, 31, 0, 17, 190, 49, 0, 9, 174, 73, 0, 3, 154, 99, 0, 1, 127, 127,
1, 0, 99, 154, 3, 0, 73, 174, 9, 0, 49, 190, 17
};

Please let me know your inputs, if we are missing something.

Appreciate your time and help.

Thanks,

Nishant
