c++ - （C ++）奇怪的位图问题 - 灰度颜色

我在C ++中创建一个Bitmap有一个奇怪的问题。我正在使用BITMAPFILEHEADER和BITMAPINFOHEADER结构来创建8位灰度图像。位图数据来自相机通过DMA，因为unsigned char与预期的长度完全相同。将图像保存为开头，它包含颜色？！

它应该是这样的：http://www.freeimagehosting.net/qd1ku
方式如下：http://www.freeimagehosting.net/83r1s

你有什么想法可以从中得到什么？

位图的标题是：

42 4D 36 00 04 00 00 00 00 00 36 00 00 00 28 00 00 00 00 02 00 00 00 02 00 00 01 00 08 00 00 00 00 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

    Info-Header:
    42 4D           Its a Bitmap
    36 00 04 00     Size of Bitmap = 0x04 00 36 - Header-Size = 512x512
    00 00 00 00     Reserved
    36 00 00 00     Offset = Sizeof(Bitmapinfoheader);
    28 00 00 00     Sizeof(Bitmapinfoheader);
    00 02 00 00     =0x200 = 512 px.
    00 02 00 00     same
    01 00           = 1 - Standard. Not used anymore.
    08 00           Color dept = 8 bit.
    00 00 00 00     Compression: 0 = none.
    00 00 00 00     Filesize or zero
    00 00 00 00     X-Dot-Per-Meter, may be left 0
    00 00 00 00     y-Dot-Per-Meter, may be left 0
    00 00 00 00     If zero, all 255 colors are used
    00 00 00 00     If zero, no color table values are used

你有什么想法来自哪里？
