Video Formats and Modes
IIDC 1.31 defines several video formats which determine the video data output from the camera. An overview of
those formats is:
Format 0: Video formats up to VGA (640 x 480) resolution.
Format 1: Video formats for SVGA (800 x 600) and XGA (1024x768) resolution.
Format 2 : Video Formats for SXGA or higher resolutions ( 1280 x 960 and 1600 x 1200 )
Format 6 : Still Images
Format 7 : Scalable images sized ( User defined size and position )
Format 0 / Format 1 / Format 2
In these formats, the frame rates are pre-defined for each video mode as per the IIDC specification.
There are several defined modes for each format where a mode specifies the size and color information of the
pixels. By reading the inquiry register of the camera, the user may determine which frame rates are supported by
the camera. Please refer to the IIDC specification for the details.
Format 7
Format modes 0, 1, & 2 were defined at the early stage of the design and development of digital industrial
cameras; where cameras supported these common VESA compliant resolutions. Because the user required a flexible
and definable format; camera manufacturers utilized the user definable Format 7 to meet this demand. Format 7
is extremely flexible and allows the user to define the width, height, position and pixel format of the video data
where separate sets of control registers exists for each Format 7 mode.
The cameras support Format 7 modes 0,1,2 with the following base address:
Format 7 Mode 0 : F1F00000h Format 7 Mode 1 : F1F00100h Format 7 Mode 0 : F1F00200h
