PicPort®-Mono-PMC, PicPort®-Stereo-PMC for monochrome analog inputs make up a comprehensive range of OEM monochrome framegrabbers. Video Image formats supported include analog CCIR, RS170 or nonstandard (incl. high resolution, high speed or dual-channel). The boards offer various real-time image conditioning functions, different synchronization modes, asynchronous acquisition, simultaneous capture, and more. The conditioned image is sent by fast DMA transfer directly to VGA and/or main memory.
The PMC version of PicPort®-Mono/Stereo series is compatible with our LVmPC® embedded vision system.
Besides the PMC module version, standard PCI bus version as well as CompactPCI version of the PicPort®-Mono/Stereo series is also available.
PicPort®-Mono-PMC and PicPort®-Stereo-PMC monochrome framegrabbers are designed for:
All the PicPort® models are based on similar architecture.
The PicPort® I/O interface generally comprises video input connectors, synchronization and opto-isolated trigger inputs and outputs. The exact physical hardware interface is model-specific.
The analog PicPort®-Mono-PMC cards feature one, PicPort®-Stereo-PMC models two digitizer channels, handling up to 4 video inputs. Besides the A/D converter, each digitizer channel contains additional circuits for image conditioning.
The Pixel Stream Manager is the real heart of every PicPort®. It consists of two data paths (DMA channels) with different features (see the figure). Data path A features the following circuits: High Performance Scaler for fine interpolating, detail-preserving, image scaling down to approx. 40 ¡Ñ 40 pixels with horizontal plus vertical mirroring, Lock Mask Control for text or graphics overlay on the top of the live image and Pixel Packer and Color Space Converter to perform conversion to a desired color format.
The second data path B contains only the Binary Ratio Scaler. Both data paths contain FIFO buffers for proper synchronizing the DMA transfers.
All boards utilize an on-board controller to guarantee performance of real time critical tasks independent of host processor or operating system.
Each PicPort® board contains a firmware EEPROM that is updated automatically by driver software en-suring compatibility between hardware and software releases. In addition two bytes of the EEPROM are available to OEM’s for use as a Software Dongle.
In general PicPort® boards accept video resolutions up to 2048 ¡Ñ 2048, 2:1 interlaced or non-interlaced mode, pixel shape in accordance with CCIR601 or square.
PicPort®-Mono/Stereo models accept video sources compliant with CCIR or RS170 video standards. In addition many non-standard cameras, i.e. progressive scan, can also be interfaced by utilizing an easy to use Camera Editor.
For PicPort®-Mono/Stereo an 8 bit, 20MHz, A-to-D is used to digitize the video input. A programmable Input LUT can be used for real-time manipulation of brightness, contrast, gain and offset.
Image scaling and mirroring are operations performed by the Pixel Stream Manager with a range of functionality dependent on the data path (DMA channel) used. DMA channel A with its High Performance Scaler uses a mathematical interpolation method independently along both x and y axes, resulting in an image free from any significant loss of detail. Alternatively, when the simpler DMA channel B is used, only vertical mirroring and binary downscaling is available.
By means of a Lock Mask feature, unique to PicPort®, image data flowing through DMA channel A can be overlaid by a 1-bit mask created as a compressed bitmap within Windows in the form of text or graphics.
By utilizing the Pixel Packer and Color Space Converter the data on DMA channel A can be converted to monochrome or RGB with predefined color and bit depths.

The digitized and conditioned data is transferred using two independent DMA channels directly to the CPU and/or video memory without on board intermediate storage and with minimal CPU intervention. The board acts as a PCI bus master allowing transfers at peak rates of up to 132 MB/s i.e. real time transfer for all acquisition modes.
The two independent DMA channels provide many modes of operation including:
Simultaneous transfer of video data from a single image source to main memory for processing and to video memory for display.
A dual channel camera, that outputs two fields of the same frame simultaneously, can be combined to build up a complete image in real time. Transfer of images from two synchronized cameras to two independent memory windows.
With PicPort®-Mono and PicPort®-Stereo models the following modes are possible:
In this mode the necessary horizontal and vertical synchronizing information is decoded from the camera’s composite CVBS video signal input. CVBS is the simplest possible synchronization mode.
In addition to the video signal, the PicPort®-Mono/Stereo models accept horizontal synchronizing pulses (line valid) and vertical synchronizing pulses (field/frame valid) from the camera or other external device.
This mode ensures 100% compatibility between the timing of both the camera and board and results in the precise mapping of each pixel to the same storage location every time. This technique results in a high quality noiseless image suitable for measurement applications.
Because the board is matching the rigid geometry of the camera only a single camera may be attached in this mode.
In this mode the PicPort®-Mono/Stereo generates H & V sync signals to control the attached camera(s). When several cameras are synchronized by a single PicPort®-Mono/Stereo a user application can switch between them during vertical retrace (blanking) without any image loss.
In Pixel Synchronized mode the PicPort® generates both H & V sync and pixel clock signals for single or multiple cameras.
The trigger input on the PicPort®-Mono/Stereo can be used with asynchronous reset cameras to initiate a new frame. Similarly output signals from the PicPort® can be used to control strobe lighting etc. Application note «External trigger and flash» gives good overview of applications involving external devices such as trigger and flash.
Leutron Vision provides PicPort®-Mono/Stereo-PMC boards with a variety of connector configurations to accommodate many special application requirements as briefly described below. Detailed pin-outs and descriptions of all the multi-connectors are available at the chapter Connector description below.
The universal camera connector comes in 25-pin D-sub female format. For older PicPort®-Mono/Stereo-PMC series, however, a 44-pin D-sub female connector was used.
In general, the connector provides connections for 4 video inputs, synchronization + clock I/O and a 12 volt camera power supply. Range of specific cables to interface various camera types are available.
For synchronization of events like start/stop, trigger, good/bad, input/output etc. PicPort® boards offer digital inputs and outputs, which can be controlled by software. For use in industrial environment, the signals are isolated by the use of optocouplers. To take full profit of this signal isolation, you have to connect the optocoupler to an external power supply.
The optocoupler input is prepared for input signals from 5 V to 24 V with the appropriate onboard serial resistors. The optooupler output is prepared for external voltage from 5 V to 24 V.
See also the following examples of optocoupler output. In industrial environment, signal levels of 24 V are usually needed.
Application note «External trigger and flash» gives good overview of applications involving external devices such as trigger and flash.
Based on the PCI bus Revision 2.1 specification PicPort® framegrabbers are available to suit a variety of different host buses.
PicPort®-Mono/Stereo series is currently available as PMC module as well as in standard PCI bus version and in CompactPCI bus version.
Leutron Vision Software Development Suite, LV-SDS, is a software development package (Windows, Linux, VxWorks) that allows full control of all PicPort® and PicProdigy® products. The suite consists of Daisy - the basic software interface for PicPort®/PicProdigy® cards, Camera Editor - easy interactive setup of standard and non-standard cameras, DRAL - a library for handling specific time-critical tasks, Orchid - high level library (DLL or OCX) for quick and easy design of PicPort®/PicProdigy® applications, TWAIN Driver and Video for Windows - provide a simple interface between Leutron Vision hardware and other office and image manipulation programs (e.g. MS Office, CorelDRAW, etc.).
The software products come complete with a set of demo programs and additional examples with source code as a guide to the programmer in developing particular applications. To obtain more comprehensive information please download the LV-SDS manual.
