No special PC requirements
The only prerequisite to use the FG-34 is a PC-System with PCI bus. We recommend use of graphic boards with Direct X support and modern operating systems such as Windows XP, 2000 or Windows 98. Direct Draw capabilities under Windows 95 & NT are used, if installed. For DOS and Windows 3.x a full-color moving online display of a video source is possible, if a special supported VGA adapter is used. Setup is easy, because the FG3x-CD handles Microsoft Windows-XP/2000/NT and Windows 98/95 systems automatically. If software is installed first - no hardware configuration is required.
Signal sources and Color processing
Video signals in PAL-, SECAM- or NTSC-Standard can be digitized by the HaSoTec Frame Grabber FG-34. Cameras, video recorder, SVHS, Hi8 or Y/C sources, as well as any other devices with video standard outputs can be connected to 6 inputs selectable by means of software. The FG-34 uses the 4:2:2 broadcast standard in conjunction with a complete digital signal path. FG-34 provides double color resolution in time and chrominance steps resulting in a remarkably better color quality than 4:1:1 standard solutions.
Precision pixels
Square pixels have advantages for many applications. The FG-34 digitizes square pixels for all TV standards. This provides true-to-scale pictures without distortion and without scalings that impair quality. These formats have better resolutions in each line, e.g. 768 instead of 752 or 720 pixels. YUV and RGB modes allow color depths of up to 24 bits/pixel. HaSoTec guarantees full use of 8 bits in each of the 3 color channels. Automatic gain control and black- level reference ensure reproducible accuracy as is needed for measurements. The Frame Grabber FG-34 has, in addition, a manual gain-control mode, which has advantages for many image-processing applications.
High resolution
FG-34 can work with variable resolutions based on a fixed grid of 768x576 pixels for European standards and 640x480 pixels for US standard. On-board video RAM is organized to supply 1024Kx8 bits, 512Kx16 bits or 256Kx32 bits, as required by the respective mode. Programmable hardware can pass a cropped window on to this RAM, which is scaled 1:1 or 1:2 in relation to the basic grid.
Grey-scale images
A special mode allows the efficient capture of grey-scale images. Four pixel with 256 grey values can be transferred by a single CPU read cycle without wait states. This allows a variety of real-time applications.
Variable memory access
To use the full performance of modern PCs for image processing, image data has often to be transferred into the PC memory. Due to the pipelined data transfer. FG-34 is able to supply image data at high speeds. After the first line is digitized, an image can be transferred into RAM simultaneously to further digitizing. It is not required to buffer the image again in PC's memory, the data stream can directly be processed in analysis loops. FG-34 has a built-in 8-bit-CPU to configure the card. Its BIOS-Chip is in a socket, so the firmware of the card can be upgradet.

Software für Win XP/2000/NT, WinMe/98/95,3.x, OS/2 und Dos
The application FG3xCLIP in its 16- and 32-bit versions works under MS-Windows XP/2000/NT, Windows Me/98/95/3.x. Image files can be loaded and saved in most commonly used formats (BMP, TIF, PCX, GIF ...). Images and parts of images can be copied into other programs by using the clipboard. Thanks to error diffusion dithering and optimized palettes, image monitoring is possible on all graphic boards, even in 16- and 256-color modes. Independent of display capabilities, all operations use a memory-based image with full pixel depth (16.7 mio colors / 256 grey levels). Numerous useful functions are built in, such as capturing frames with averaging or with look-up-table manipulations...
FG3xCAP allows one to capture AVI sequences both compressed and uncompressed into RAM or to hard disk. Time-lapse records are possible. The FG-34 software also includes a 16-bit and a 32-bit driver for the image-processing development package "Ad Oculos" and a Twain driver. The program FG30VGA, running under Dos, captures grey scale and color images using any VGA board. Many image file formats are implemented. SVGA chip sets are supported by an additional Dos program.
Writing own programs...
At no additional charge, each package contains a toolbox with programming examples in source code and language-specific libraries for MS-Windows XP/2000/NT, Windows Me/98/95/3.x, Dos and OS/2. The sample application FGIMAGE has 6 dialog boxes for making all manner of adjustments. Furthermore it displays the video source in a dialog box and shows in source code how to capture and display images in a Window. FGIMAGE is included in 9 versions for 32- and 16-bit-compilers, see the table below.
