The MODE structure contains information about the operation mode of the frame grabber. The
settings that are controlled by MODE cannot be changed on a frame to frame basis.
format
Defines the format of the video signal:
FORMAT_NTSC – NTSC (60Hz) video;
FORMAT_PAL – PAL or SECAM (50Hz) video.
bmpflip
Uncompressed bitmap lines order:
FLIP_OFF – bitmap is stored in memory in “natural” lines order (top line first). If displayed
by Windows API functions, the image will look upside down.
FLIP_ON – bitmap is stored in memory in Windows lines order (bottom line first).
bmpcolor
Color format of the uncompressed bitmap:
COLOR_MONO – monochrome, 1 byte per pixel;
COLOR_RGB – color, 3 bytes per pixel;
COLOR_YCRCB – color, 2 bytes per pixel, YCrCb (byte sequence: CbYCrY…);
COLOR_YCRCB_BS – color, 2 bytes per pixel, YCrCb (byte sequence: YCbYCr…).
bmpsize
Uncompressed bitmap size:
BMP_SIZE_LRG – large bitmap (256x192);
BMP_SIZE_SML – small bitmap (128x96).
jpgsize
Compressed (JPEG) image size:
JPG_SIZE_FULL - full size JPEG, 704x480 (NTSC) or 704x576 (PAL);
JPG_SIZE_FULL_C – clipped full size JPEG, 640x480 (NTSC), not valid for PAL;
JPG_SIZE_HALF - half size JPEG, 352x240 (NTSC) or 352x288 (PAL);
JPG_SIZE_HALF_C – clipped half size JPEG, 320x240 (NTSC), not valid for PAL;
captionformat
Caption window format:
