Digital Camera 1.1. Cleaning the sensor IDT recommends that the sensor NOT be manipulated in any fashion. Clean the optical surfaces with filtered, compressed air and glass cleaner or distilled water. Use a cotton swab or lens paper. Do not use alcohol or other solvents as these may damage the optical coating and cements.
IDT, Inc. provides warrants to the original purchaser that, from the date of delivery, the hardware components of the sharpVISION™ Digital Camera (the “Product”) will be in good working condition for a period of one (1) year on all parts. Should any of the components of this Product fail to be in good working order at any time during this warranty period, IDT, Inc.
Digital Camera 3.1. Introduction to the sharpVISION™ Camera The sharpVISION™ digital cameras are high-resolution, high-performance cameras to be used in industrial and scientific applications that include machine vision, microscopy and Particle Image Velocimetry (PIV). The sharpVISION™ cameras are built around the scientific grade SONY ICX sensors.
API supplied by IDT. 3.2. Note on cross-platform manual The cross-platform manual provides instructions on using the sharpVISION digital camera on the Windows and MAC OS/X platforms. The Windows and MAC icons below denote differences in setup, procedures and commands between Windows and MAC users.
Digital Camera 3.3. Software Development Kit Upon the installation of the sharpVISION software package several options are available to the user. These options are easily accessed via the Program menu under the Windows Start button. The programs and associated files are organized under the IDT/sharpVISION folder.
Digital Camera This section specifies the minimum recommended computer requirements and gives the procedures needed to install the Camera Head, Camera Cable, Power Supply, I/O Cable, and software. 4.1. Minimum computer requirements Operating System Windows 2000, Windows XP Processor Pentium III or equivalent with 500 MHz processor.
Digital Camera 4.3. Software Installation Windows 2000/XP Before installing the software make sure that the computer has Windows 2000 or Windows XP installed as operating system. 1. Log into Windows with a username and password that has ADMINISTRATIVE PRIVILEGES.
Digital Camera 4.4. Hardware installation The camera gets the necessary power from the computer via the fire-wire cable. If the power provided by the PC is not enough an additional power supply unit is included with the camera system package. The external power supply is only required when a laptop and/or a 6 to 4 pin cable is used.
Digital Camera Power Connector 4.5. Camera lens adapter The camera is supplied with a standard C-mount. Alternatively, a C to F mount adapter is available to interface with F-mount (Nikon type) lenses. Use Nikon lenses with a tilt/shift capability when imaging at an angle. As an option, mounting hardware for tilt/shift lenses by Canon is also available.
Digital Camera ™ ™ 5.1. Overview This application allows the user to acquire, save/play-back image records, and control the camera in Single or Double Exposure modes. The GUI for the application is shown below. Using the Camera Control dialog box, the user may interactively select the camera operating modes as well as other parameters like exposure, binning, and so on.
Digital Camera 5.2. sharpVISION™ menu structure The X-Vision main menu bar contains the following options: File Camera View Help 5.3. File Menu The File menu contains the following options: • Save on the hard disk Images • Close the program and exit.
Digital Camera 5.4. Save images Each acquired sequence may be opened and saved in a different format. 1. From the main menu select File > Save Images… or 2. Click the Save Images button on the toolbar. 3. Click Browse... if you want to change the acquisitions directory.
Digital Camera 5.5. Camera Menu The camera menu on the main menu offers an alternative to using the buttons provided by the main toolbar, including the following options: 1. Record a sequence. 2. Stop play of images or Snap a single image.
Digital Camera 5.6. Camera Control The camera configuration parameters may be interactively changed by opening the camera settings dialog box. The user may set the camera in play mode and adjust the parameters. Exposure Time Use the f-stop buttons to select a new exposure value. The value is in microseconds Rate The current camera rate is updated any time a parameter changes.
Page 19
Digital Camera This parameter controls the speed at which the image data is read from the CCD. The supported values are: 20 MHz, 10 MHz, 5 MHz and 2MHz. Exposure Mode Use the drop-down list to select either Single or Double exposure mode.
Digital Camera 5.6.1. Set a region of interest (ROI) The sharpVISION camera has a Partial Windowing capability that can be selected and set via the software interface. Using this setting a region of interest for the image that is less than the total available area of the sensor may be selected.
Digital Camera 5.7. Record Settings The Record Settings dialog box allows the user to select the recording parameters. The images may be acquired directly to RAM or to the selected directory on the hard disk. When images are recorded they are streamed to HOST RAM. The maximum number of images that can be streamed at the video rate to HOST memory depends on the maximum system capacity and the number that the user allows.

Digital Camera Enable automatic save… If this option is selected, the program stores the images to the hard disk immediately after the acquisition. Acquisition folder Name The parameter indicates the directory in the hard disk where the acquired images will be stored.
Digital Camera 5.8. View Menu Use the View menu to magnify the image, restore the original size (100% zoom) or compute a zoom factor that fits in the window 5.9. Help Menu This menu contains support options and information including: e-mail tech support and software and manual updates.
Digital Camera Some common troubleshooting scenarios are listed in the table below: Symptom Camera LED not ON Cannot control camera through IEEE-1394 port Image occasionally goes bright on one side or stays dark on one side Hazy image or poor contrast.

Digital Camera 7.2. Spectral Sensitivity NOTE: optional cooling reduces the thermal noise at long exposures. The dark current is reduced. 7.3. Lenses and mounts C–mount or F–mount lenses can be readily interfaced to the cameras. The standard lens is Nikon 50 mm.
Digital Camera 7.4. Trigger connector The camera generates image data that is sent to the host interface via the IEEE-1394 cable. The camera can be controlled from the host computer via this cable. The auxiliary power supply provides power in those cases where power is unavailable from the host computer.
Digital Camera 7.5. Cables Included with the camera there are two cables: IEEE 1394 Data Cable Trigger Cable This is a IEEE-1394 6-pin interface cable. This cable can be plugged into either of the available ports at the back of the camera and it provides the connection with the 6-pin IEEE1394 port in the host computer.
Digital Camera sharpVISION supports the image formats listed in the table below: Format Tagged Image File Format - TIFF™ Windows™ Bitmap Portable network Graphics – PNG Multi-Page TIFF Multi-page Raw Multi-page Compressed Audio Video Interleaved (AVI) Apple Quick Time (MOV)
Digital Camera 8.1.3. PNG Format PNG is an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and true-color images are supported, plus an optional alpha channel.
Digital Camera 8.1.8. Multi-page Raw Format (MRF) Multi-page Raw Format (MRF) is an uncompressed IDT proprietary file format. Multiple raster images are stored in a single file. The format is described below. Each MRF file contains a file header, an image header and an array of bytes that defines the image data bits.
Digital Camera nWidth: width of each image in pixels. nHeight: height of each image in pixels. nBPP: number of bits per pixels (8, 10 or12) userData: an array of 64 unsigned long that may be user by the user to store other information.
Digital Camera typedef struct _RCIMG_HEADER unsigned long nSize; unsigned long nPages; unsigned long nWidth; unsigned long nHeight; unsigned long nBPP; unsigned long userData[64]; } RCIMG_HEADER, *PRCIMG_HEADER; Members nSize: size of the structure in bytes. It should be 84. nPages: number of images contained in the file nWidth: width of each image in pixels.
