    Signal Vin LED Vin Imager Pixel Clock (PCLK) Electrical Interface Considerations When designing the host system circuitry with a switched V into the imager I/O lines. Leakage back into the imager I/O causes the imager V pull-ups, protection diodes, and parasitic FET diodes. This results in unwanted current draw and causes the imager's power up reset system to fail.

  • Page 14: Vertical

    Vertical The vertical timing is configured with the active row start value (reg 0x15, 0x14) where the last 485 active rows, or lines of video, of a 525 row frame are output immediately after the leading edge of the vertical signal, and the first five rows appear at the end of the frame.

  • Page 15: Changes In Exposure Value Vs. Frame Height

    Changes in Exposure Value vs. Frame Height The time (measured in frames) for a new exposure to fully take effect is dependent on the absolute value of the change in exposure (in rows) as it relates to the difference of the frame height (FH) minus the last active video row (LAVR). An exposure change that is greater than the frame height/last active row difference requires two frames before the new exposure takes full effect.

  • Page 16: The Effects Of Timing On Noise

    Initial Configuration (FPGA, ASIC) The register settings of the initial Hand Held Products configuration are shown in the following table. The configuration generates timing signals that create data acquisition windows for frame (vertical) and horizontal (row, line) data valid regions. The timing is based on the IC Media default frame height and line width that provide a frame rate of 30 fps.

    Note the row/line data relationship within each frame. The data presented within each line is the data from that line.

    Image Acquisition Timeline The following is graphical timing reference of the image acquisition for the IT4X00 Series engines using the Hand Held Products windowed acquisition configuration. The figure shows details of the I2C and line data events which are required by the hardware and image acquisition software layers.
  • Page 27 Using this method, the host system can be placed to sleep for greater periods of time early in the acquisition. The back end method also requires that a minimum of 5 LDEs occur between the mid point of the frame capture and the vertical interrupt. The image acquisition layer requires this from the host system for proper re-allocation of the frame buffers and to prepare to write the next exposure values.

  • Page 37: Chapter 4 - Optics And Illumination

    Optics and Illumination Window Placement Distance from Window The window should be mounted close to the front of the image engine (parallel, no tilt). The maximum distance is measured from the front of the imager housing to the farthest surface of the window. Since unwanted reflections can occur at either surface and the window thickness can vary, the further side is the worst case.

  • Page 38: Code Presentation Angle

    Window Size Diagram Units = Inches [mm] Code Presentation Angle Codes printed on glossy or laminated paper are best read at angles greater than 5° in relation to the scanner. This prevents bright illumination reflections from being returned to the scanner. Ambient Light The IT4X00 Series engine performs best in the presence of at least 50fc (535 lux) of ambient light.

  • Page 39: Eye Safety Standard For It4000/It4100 Series Engines

    LEDs The IT4000 and IT4100 engines have no lasers. The IT4000 and IT4100 engines have light emitting diodes (LEDs) that create the aimer line and illumination. These LEDs are bright, but testing has been done to demonstrate that the engine is safe for its intended application under normal usage conditions.
  • Page 40 The IT4000 and IT4100 engines are certified as Class 1, the safest level. This level includes relatively dim indicator LEDs and other sources that are brighter than the IT4000 and IT4100 engines. This means the engine is safe under reasonably foreseeable conditions of operation .

    FIFO Depth Based on System Assessment The depth of the FIFO for the image capture system with DMA to main system memory is dependent on many factors that govern the system performance, and may be different for every design. FIFO depth must equal the number of memory bytes needed to store all image data acquired during the longest system delay (latency) that restricts DMA access to the bus, based on an image acquisition rate of 13.5MB/s.
