    Capture Mode Capture Mode Definition: Capture Mode relates to the way that images are captured and processed. Serial Cmd: <K241,capture mode,number of captures,rapid capture mode,pre-processing> Default: Continuous Capture Options: 0 = Rapid Capture 1 = Continuous Capture Rapid Capture Definition: In a rapid capture mode, one or multiple captures (as many as 32) can be taken at an interval specified by the time-between-captures parameter.
  • Page 141 Read Cycle Number of Captures Usage: Number of Captures is used to specify the number of captures to be processed in Rapid Capture Mode. Definition: Sets the total number of captures that are processed during a read cycle in Rapid Capture Mode. This feature is used in conjunction with Capture Timing parameters to specify the capture sequence of a rapid capture read cycle.

  • Page 142: Timed Capture

    Capture Mode Timed Capture Usage: Timed Rapid Capture is useful in fast-moving applications in which symbols are only in the field of view for a short time and precise timing is required. Definition: In Timed Rapid Capture, decoding occurs independent of and simultaneous with capturing, thus allowing precise timing or no delay at all between captures.

  • Page 143: Triggered Capture

    Read Cycle Triggered Capture Usage: Useful in applications where each decode must be treated as a discrete event, regardless of symbol data. Definition: The first trigger event starts the read cycle, and subsequent triggers will continue until the predetermined Number of Captures is met, or until the predetermined End of Read Cycle condition is met-- whichever occurs first.
  • Page 144 Pre-Processing Definition: When enabled, this feature reduces the time between image capture and decode by beginning the processing task while an image is being captured. Serial Cmd: <K241,capture mode,number of captures,rapid capture mode,pre-processing> Default: Enabled Options: 0 = Disabled 1 = Enabled Disabled When Pre-Processing is disabled, the imager can process previously captured images while image capture events are taking place.

  • Page 145: Capture Timing

    Read Cycle Capture Timing Note: Capture Timing applies only to Rapid Capture Mode. Time Before First Capture Usage: In almost any moving line application, a time delay is needed to ensure that a symbol will be in the imager’s field of view at the beginning of the capture sequence.

  • Page 146: Time Between Captures

    Capture Timing Time Between Captures Usage: This is useful in applications where more than one symbol can appear during a single read cycle (multisymbol), or where line speeds are slow enough that captured frames might overlap or miss a symbol. Definition: A time delay can be inserted between individual frame captures in Rapid Capture Mode.

  • Page 147: Image Storage

    Read Cycle Image Storage Image Storage Type Definition: Allows the user to store images from separate read cycles and to retrieve them later. The number of available slots for storage depends on the mode of operation. If the imager is in Rapid Capture Mode, the number of images that can be stored is equivalent to the maximum number of the rapid count (the current rapid count setting).
