No special PC requirements
The only prerequisite for using the FG-31 is a PC-System with PCI bus and VGA- graphics. We recommend use of graphic boards with Direct X support and modern operating systems such as Windows Vista, XP, 2000 or Windows 98. Accelerated by special FG-31 driver functions a full-color moving online display of a video source is possible. For older operating systems such as Dos or Windows 3.x a moving online display requires one of the special supported VGA adapters.
Signal sources
Videosignals in PAL-, SECAM- or NTSC-Standard can be digitized by the HaSoTec Frame Grabber FG-31. Cameras, video recorders, SVHS, Hi8 or Y/C sources, as well as any other devices with video standard outputs can be connected to 3 inputs selectable by means of software.
Color quality
Working at 4:2:2 broadcast standard in conjunction with a complete digital signal path FG-31 provides double color resolution in time and chrominance steps resulting in a remarkably better color quality than standard solutions.
Precision pixels
Square pixels have advantages for many applications. The FG-31 digitizes square pixels for all TV standards. This provides true-to-scale pictures without distortion and without scalings that impair quality. Six modes allow color depths up to 24 bit/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.
High resolution
FG-31 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 960Kx9 bits, 480Kx18 bits or 240Kx36 bits, according to the selected mode. A programmable hardware can pass to this RAM a cropped window 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.
Quick memory access
To use the full performance of modern PCs for image processing, image data often has to be transferred into the PC memory. Due to the pipelined data transfer even fastest PCs don't need wait states. After the 1st line is digitized, an image can be transferred into RAM simultaneously to further digitizing.
Software for Win Vista/XP/2000/NT/Me/98/95/3.x, Dos and OS/2 (supplied with all cards)
The program FG32VGA, running under DOS, captures grey scale and color images using any VGA board. Many image file formats are implemented. HiCOLOR graphic boards with ET4000 chipset are supported by an additional DOS program. The application FG32CLIP in its 16- and 32-bit versions works under MS-Windows 3.x/'95/NT and OS/2. 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). The FG-31 board and software furthermore includes a 16-bit and a 32-bit driver for the image processing development package "Ad Oculos".
Nothing is easier than to write own programs
Add no additional charge each package contains a toolbox with programming examples in source code and laguage-specific libraries for DOS, MS-Windows 3.x, MS-Windows 95/ NT and OS/2. The sample application FGIMAGE has 6 dialog boxes for making all manner 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 16-bit-compilers: Microsoft C/C++ 7.0 - C example, Microsoft C/C++ 7.0 C++ example running both in all Visual C Versions up to V.1.52, Borland C++ 3.1/4.0 - C example, Microsoft Visual Basic examples (1.0-3.0 and 4.0-5.0), Turbo Pascal 7.0 example, Delphi 1.0 example, IBM C/2 (OS/2) example, Borland C++ 2.0 (OS/2) example. DOS examples for Borland C, Microsoft C, Turbo Pascal and 2x Quick Basic complete the package. A 32-bit-OCX Control to work under MS-Windows 95 and NT comes with source code examples for MS Visual C++ 4.x, Delphi 2.0, Visual Basic 4.0 and is usable under MS-Access 95/97 and Visual Foxpro 3.x.
